In celebration of Fun at Work Day, Tata & Howard employees took a break from lunch and competed in The Marshmallow Challenge!
Made popular by TED Talks’ Tom Wujec, The Marshmallow Challenge is simple – teams compete to build the tallest freestanding structure in 18 minutes using only 20 sticks of spaghetti, a yard of tape, a yard of string, and one marshmallow. The marshmallow needs to sit on top of the freestanding structure.
Did we mention the challenge is simple? Well…interestingly the challenge is not as simple as it seems – the marshmallow is pretty heavy! In addition, time ticks away very quickly!
While we were having some ‘Fun at Work’, The Marshmallow Challenge was also a terrific team building exercise and we did learn some valuable lessons.
Key lessons we learned from this challenge:
Teamwork is key. Every team member needed to contribute. Working well together was especially effective and efficient.
Testing: Working out theories and testing materials early in the challenge helped formulate the overall design. However, taking too long in the planning impacted the construction time.
Time Management. As we learned from the testing phase, time management turned out to be an equally important lesson. Teams needed to plan and manage enough time to build the structure.
Innovation: Creativity and originality was really the fun part of this challenge. All teams approached this challenge differently and every structure was unique.
Here’s a blow-by-blow account of the competing teams:
At our Marlborough office five teams competed:
Table 1 – Mike, Molly and Maya spent a good part of the time planning and testing. They also exercised good time management and built a very stable structure reaching 15 ½”.
Table 2 – Using all their materials, Katie, Jenna and Meghan built the tallest structure at 16 1/2”. Although not the prettiest to look at, it was very stable and even with vigorous table shaking the tower stood tall! Winning Team!!
Table 3 – Brian, Maria, and Derek had the sad misfortune of their structure collapsing shamelessly into a ½” pile of broken spaghetti!
Table 4 – Although, James, Mary and Karen’s structure measured 10 1/2” after partially collapsing, they finished with time to spare and managed to have some materials left over!
Table 5 – Adam, Matt and Jim ambitiously engineered a very tall structure, but it sadly collapsed under its own weight. Still, there were some measurable structural components and came in at 8” high.
At our Waterbury, CT office, two teams competed:
The Seniors (Sal, Bill, Dave and Nan) had an early lead and constructed a fairly stable structure of modest height with about 5 minutes left. However, their table was jarred, and the structure ended up toppling. They could not re-assemble before time ran out.
The Young professionals (Chelsea, Ryan, Kevin, Will, Natalia) used the early stages to plan the construction and had some good ideas, however, they were a little too ambitious with the final marshmallow top and their structure also collapsed. In fact, it never really stood at all. And, the final height of their marshmallow was below the table surface!
In less than an hour, the Marshmallow Challenge is a fun way to foster innovation and teamwork. If you’re interested, the challenge rules can be seen here [Marshmallow Challenge Instructions]. Hope you find time to have fun at work too!
Tata & Howard is a 100% employee-owned company, or ESOP. Being an ESOP is an integral part of our corporate culture, and we consistently strive to enhance our core values of teamwork, innovative solutions, positive attitude, efficiency, and integrity through teambuilding activities throughout the year. October is ESOP Month, celebrated by ESOP companies across the United States, and an excellent time for all of us at Tata & Howard to focus on the benefits of employee-ownership as well as the core values that have been with us since our inception in 1992.
Earlier in the month, we showcased how our four ESOP committees – Communications, Green, Philanthropy, and Wellness – planned a month of activities for the Tata & Howard team, Harry Potter style. The first half of the month saw a philanthropic initiative to raise funds for the Dana-Farber Cancer Institute, a community trash cleanup day, and a “Minute to Win It” challenge, as well as various food-themed events. The second half of ESOP Month was also filled with fun and festive activities, including the firm’s official 25th anniversary.
On October 19, Tata & Howard officially turned 25 years old. Founded on October 19, 1992, Tata & Howard has grown from a two-person startup to a thriving 70-person firm with nine offices in seven states as well as Ontario, Canada. On October 19, all offices were treated to a celebratory catered lunch, where Co-President Karen Gracey and Co-Founder and Senior Vice President Paul Howard spoke to the entire team about the history of the firm as well as goals for the future. After the speeches, everyone raised a champagne toast for 25 exceptional years in business — and for 25 more — after which we all received Tata & Howard branded fleece jackets.
On Saturday, October 21, we celebrated our 25th anniversary in style, beginning at the Boston Museum of Science, where 70 T&H employee-owners (EOs) and their guests participated in a Murder Mystery Scavenger Hunt throughout the museum. Broken into 10 teams, EOs received 24 clues and a coded sheet and were given two hours to complete their assignment. The hunt was highly entertaining while also providing EOs the chance to get to know their fellow EOs from other offices a bit better. Not surprisingly, six of the ten teams fully completed the challenge with all correct answers, so the winner was determined through some tie-breaking trivia questions about the museum. The winning team was Team 2 Beat, who were all smiles for the photo!
After completing the scavenger hunt, EOs headed over to the Union Oyster House, the oldest restaurant in the United States, where we enjoyed appetizers and drinks in a private room. Once everyone had arrived, a theater troupe from Monson, MA (one of our clients!) began their performance of Trial & Error, a hilarious interactive show that takes place in a courtroom. Each act was given between courses, and the laughter could be heard throughout the restaurant. At the end of the night, we cut into our special 25th anniversary cake and savored the sweet taste of success. The night was highly enjoyable and a true celebration of our firm’s incredible accomplishments.
Also during the second half of ESOP Month, EOs participated in a paper airplane contest. EOs in all offices had ten minutes to make paper airplanes out of standard copy paper. No glue, tape, paper clips, tearing, or puncturing of the paper were allowed. After the planes were built, it was time to test! Points were awarded on a basis of longest distance flown as well as longest air time. First, second, and third place winners in each category won points for their houses. Adam Carrier took top spot for distance with 37.3 feet flown, and James Hoyt won first place for airtime with 3.1 seconds. Jon Gregory and William Grant came in second and third, respectively, in both events, with distances of 37.2 feet and 36.7 feet, and airtimes of 2.65 seconds and 2.6 seconds.
Another friendlier challenge was our thank you note challenge, sponsored by the Philanthropy Committee. EOs were asked to send thank you notes or emails to their fellow co-workers, and for every thank you they sent, the ESOP Committee would send $1.00 to DARE Family Services, with a three thank you note per EO cap. The day brought lots of smiles as people received special messages of appreciation, and we ended up collecting $108 to send to DARE. The event was well received and reminded everyone to show gratitude.
During the last week of ESOP Month, EOs participated in a step competition, sponsored by our Wellness Committee. The team with the highest total steps as well as the team with the most participation would receive points for their houses. Over half the company participated, and collectively we racked up an astounding 1,754,372 steps! That’s the equivalent of walking from Marlborough, Massachusetts to Cincinnati, Ohio.
To wrap up ESOP Month, EOs got together after work on Monday, October 30 to enjoy some home baked pumpkin treats and pumpkin beer while we decorated mini pumpkins. On Halloween, the house points were tallied, and we are happy to announce that Ravenclaw wins the House Cup! All in all, ESOP Month was another huge success, and we are already planning for next year.
As a 100% employee-owned company, Tata & Howard has a unique culture that celebrates teamwork, efficiency, integrity, positivity, philanthropy, sustainability, and yes, even fun. ESOP Month is celebrated by ESOP companies throughout the United States in October each year, and it serves as an excellent reminder of the many reasons why being part of an ESOP is such an exciting opportunity. Throughout the month, employee-owners (EOs) participate in challenges, activities, educational sessions, and philanthropic initiatives that embody the essence of ESOP culture and serve to remind EOs of the incredible benefits realized by being part of an ESOP company.
At Tata & Howard, our four ESOP committees – Communications, Green, Philanthropy, and Wellness – got together to plan a month’s worth of festivities. The month kicked off with cider donuts, cider, and coffee in all offices, after which EOs were sorted into houses, Harry Potter style. EOs will stay in their house for the month and houses will collect points based on participation and success in challenges. The house with the most points at the end of the month is declared the winner and receives the House Cup.
Our first challenge was a philanthropic initiative. EOs were asked to donate to Dana-Farber Cancer Institute, and the company offered to match all donations dollar for dollar. Both participation and total donation amounts were important; therefore, lots of pledging took place over the next week. The houses were evenly matched and only after some last minute pledging did Ravenclaw win for total donation, while Slytherin took home the participation prize. The most impressive statistic is that 80% of our EOs participated in this important event. The total tally after the company match was $6,650!
Also during week 1, EOs celebrated National Taco Day, which officially fell on October 4. Some offices had a taco potluck and others grabbed tacos from a local restaurant, but all offices enjoyed National Taco Day and spending some downtime together.
Week 2 brought on a whole new set of challenges. EOs participated in a “Minute to Win It” challenge that included building the tallest possible tower out of spaghetti and marshmallows in five minutes, and three one minute challenges including moving piles of index cards by sucking them up with a straw, moving marshmallows with chopsticks, and eating a cookie from one’s forehead without using hands. Needless to say, laughs abounded and we learned who eats a lot of ramen and who has experience with forehead cookie eating! Points were again awarded for both participation and winning challenges.
On Friday of Week 2, EOs headed outside at all offices to pick up trash in their local communities. It was a beautiful, sunny day and EOs were successful in cleaning up their areas while enjoying camaraderie. Only participation points were awarded since we couldn’t get any volunteers to weigh the trash collected. At the end of week 2, the standings were as follows:
Next week’s plans include a thank you note challenge and a paper airplane challenge, as well as our 25th anniversary celebration. Stay tuned for updates!
Site cleanup is well understood to be critical to the health of our planet. Since site contamination affects the quality of air, land, and water, it is clear that remediating contaminated sites is paramount to the environmental viability of the nation. However, site cleanup isn’t just about greening the nation; rather, site cleanup provides a myriad of environmental, health, and socioeconomic benefits, some of which may be surprising.
There are over 500,000 brownfields currently in the United States. A brownfield is defined as any land in the United States that is abandoned or underused because redevelopment of said site is complicated by environmental contamination. Brownfield sites are not to be confused with Superfund sites, of which there are over 1,300 in the United States. A Superfund site is a contaminated area of land that has been identified by the United States Environmental Protection Agency (EPA) as needing cleanup due to the risk it poses to environmental and/or human health. Superfund sites are placed on the National Priorities List (NPL) and are eligible for government funding through the Superfund program that was established as the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA). Unlike Superfund sites, brownfields generally do not pose an immediate or serious risk to the environment or human health, as they typically have a lesser degree of contamination. Brownfields do, however, compromise the economic and social viability of our nation by preventing development, which causes numerous problems.
Because site cleanup can be expensive, brownfields are often left in states of ruin and decay. Brownfields disallow redevelopment, forcing communities to find new areas to develop, contributing to the degradation of inner cities and increased urban sprawl. Since we now understand that new urbanism — or the planning and development of compact cities that are walkable with accessible shopping and public spaces — promotes healthier cities and lifestyles, urban sprawl is also understood to be detrimental to the health of both cities and the environment. Cleaning up and redeveloping brownfields is one of the most effective ways to limit urban sprawl and to promote new urbanism, and fortunately, funding is available for brownfield remediation.
The EPA launched the Brownfields Program in 1995 to provide funding for brownfield remediation. The Brownfields Program includes the following grant programs:
Brownfields Assessment Grants: funding for Brownfields inventories, planning, environmental assessments, and community outreach
Brownfields Revolving Loan Fund Grants: funding to capitalize loans that are used to clean up brownfields
Brownfields Cleanup Grants: funding to carry out cleanup activities at brownfield sites owned by the applicant
Brownfields Area-Wide Planning Grants: funding to communities to research, plan, and develop implementation strategies for cleaning up and revitalizing a specific area affected by one or more brownfields sites
Brownfields Job Training Grants: funding for environmental training for residents of Brownfields communities
In 2002, the Program was expanded when Congress passed the Small Business Liability Relief and Brownfields Revitalization Act, more commonly known as the Brownfields Law. Since the enactment of the Brownfields Law, the EPA has awarded over 1,000 grants totaling over $200 million to public and private sector organizations.
Cleaning up brownfields not only promotes new urbanism by reducing urban sprawl and inner city decay, but also increases surrounding property values, resulting in an increased tax base. These cleaned up sites allow for the utilization of existing infrastructure and transit and therefore contribute to the economic health of cities by eliminating the need for additional municipal infrastructure. Site cleanup also helps to eliminate urban arson, vandalism, and the threat of injury from dilapidated structures and areas. Since site cleanup also reduces the need to develop open land, brownfield remediation contributes to the protection of our natural resources and environment while beautifying urban landscapes. In some instances, brownfield remediation even allows for the preservation of historical landmarks and architecture that would otherwise require demolition.
And let’s not forget about health. Site cleanup eliminates the contamination that threatens our environment. Our water, air, and soil is protected from the initial contamination as well as future contamination. Even when contamination is initially minimal, deteriorating buildings and abandoned property have the potential to increase contamination as degrading building components leach into the soil and water.
One thing to keep in mind is there is some potential risk associated with brownfield remediation. If not managed or handled properly, contaminated soil could potentially result in further contamination by migrating to surrounding land through groundwater or even runoff into surface water. To significantly reduce these risks, it is recommended and often required to utilize an environmental professional when cleaning up brownfields. In Massachusetts, for example, it is required to have a Licensed Site Professional provide evaluation both before and after cleanup to ensure that all regulations, technologies, and construction best practices were strictly followed and that the contamination has been successfully remediated.
Site cleanup clearly has significant value when it comes to the health of our nation’s environment, economy, and citizens. More and more, communities are seeking to implement new urbanism and the gentrification of cities, forcing developers to seek ways to redevelop previously unusable land. With smart city planning, the availability of brownfield grants, and the utilization of environmental professionals, site cleanup will continue to provide significant value to the economic, environmental, and physical health of communities throughout the country for years to come.
Municipal water treatment and distribution requires an exorbitant amount of resources, wreaking havoc on the environment and on budgets. And it’s getting worse. Over the past several years, operating costs have consistently been on the rise, while municipal budgets continue to shrink. In addition, regulatory requirements are increasing, forcing municipalities to upgrade treatment processes ahead of schedule. These changes result in limited unsustainable systems and utilities scrambling to find ways to manage their insufficient operational budgets while maintaining levels of service. The good news is that low-cost initiatives exist that can provide quick and significant cost and environmental savings and increase system sustainability.
When incorporating sustainability into water systems, utilities consistently rank capital cost, life-cycle costs, and service lifetime as the top three considerations, while climate change and habitat protection are the lowest ranked factors. These statistics highlight the extreme fiscal challenges facing utilities today. While environmental factors are certainly important, water systems simply do not have the luxury to place them above financial concerns, as budgets are reaching a critical juncture. In short, cost drives decision-making. Fortunately, energy efficiency and sustainability result in a healthier environment, even when implemented primarily for cost-savings.
There are many technologies and practices that water systems employ to increase sustainability and energy efficiency, the most common of which is reducing non-revenue water (NRW). NRW includes real losses, the majority of which is the result of leaks in the distribution system. In fact, the United States loses about seven billion gallons of water every day to leaking pipes — enough to supply the nation’s ten largest cities with water — and this lost water puts a strain on supply, budgets, and the environment. Reducing NRW is most easily accomplished with a water audit, which helps water systems identify the causes and true costs of water loss, and develop strategies to reduce water loss and recapture lost revenue. Water audits are often the most cost-effective and efficient solution to increasing demand, and the return on investment of a water audit is typically less than one year. Effective water loss control programs reduce the need for facility upgrades and expansions as well as the need to find additional sources, while the recovered water helps systems to generate revenue and meet demand. In addition, an effective water loss control program protects public health by identifying the leaks from which disease‐causing pathogens can enter the system.
Other technologies and practices include educating customers on water conservation, source water protection planning, automated meter reading, and trenchless pipe repair, as well as energy audits. When water utilities decide to integrate sustainability and efficiency into their operations and infrastructure, the best place to start is with water loss. Water loss reduction initiatives tend to have a quick return on investment while providing significant cost and environmental savings. Once the effects of these savings are realized, implementing other green initiatives becomes more appealing and justifiable to management and water boards.
For new treatment plants, incorporating sustainability and efficiency features into the initial design allows the plant to function at a superior efficiency level right from the start. As an example, Tata & Howard provided design, permitting, and construction services for the new Dissolved Air Flotation (DAF) Long Pond Water Treatment Plant in Falmouth, MA. The project consisted of the construction of a new 8.0 mgd water treatment plant (WTP) for the existing Long Pond surface water supply. The existing Long Pond Pump Station, constructed in the 1890s, operated under a Filtration Waiver issued by the Massachusetts Department of Environmental Protection and did not include filtration processes to remove algae, organics, or particulates from the water. The new WTP provides the Town with several key benefits:
Meets the current regulatory requirements of the Long Term 2 Enhanced Surface Water Treatment Rule;
Reduces disinfection by-products and organics;
Removes pathogens, taste, odor, and algae/algae toxins;
Produces stable water quality;
Provides the flexibility to meet uncertain future regulatory and water quality challenges.
In addition to providing a solution to the water challenges faced by the Town of Falmouth, the Long Pond WTP also provided more sustainable and efficient operations, saving the Town money while also protecting the environment. Some of these initiatives included the following:
Recycling spent backwash water to head of plant and back into the treatment process, after it passes through a plate settler to remove solids;
Recycling laboratory analyzer and filter influent piping gallery analyzer discharges back into the treatment process;
Using filter-to-waste water after a filter backwash sequence as supply water for the next backwash, instead of using finished water for backwashing;
Discharging cleaner supernatant water off the top of the lined lagoons to an unlined infiltration lagoon and back into the ground to minimize residuals;
Use of local/native plants for landscaping, including an irrigation system using collected rainwater from roof drainage;
Interior and exterior LED lighting fixtures; and
Variable Frequency Drives (VFDs) on HVAC equipment and process equipment motors.
Efficiency and sustainability are no longer considered luxuries for water systems. Rather, incorporating green initiatives into infrastructure design and operational standards has become crucial to the future sustainability of water systems. And while utilities today value cost-effectiveness over environmentalism due to the criticality of their budgets, there will likely be a shift in thinking as these systems ease the burden of their unsustainable operational costs through effective practices such as efficiency and water loss reduction.
Pollution Prevention Week takes place each year during the third week in September. This special week celebrates the passing of the Pollution Prevention Act in 1990, and serves as an opportunity for businesses, individuals, governments, organizations, and groups to focus on pollution prevention (P2) by celebrating their sustainability achievements, expanding current practices, and implementing new initiatives. In addition, P2 Week serves to remind individuals and organizations of the myriad ways that pollution can be prevented.
While many organizations and initiatives focus on recycling and mitigation, the most efficient and beneficial way to protect the environment is to avoid pollution in the first place. Once the environment has been compromised, it is much more labor intensive, energy intensive, and costly to return conditions to their natural state. For example, ensuring that double-walled Underground Storage Tanks (USTs) are maintained and in good condition is critical to the protection of groundwater and soil. When a UST leaks and contaminates the surrounding area, soil remediation is required, which in some cases can cost hundreds of thousands of dollars. In addition, any contaminated water will require a much more comprehensive treatment train, leading to expensive infrastructure projects and higher operational costs for water utilities. Preventing the leak in the first place requires simple maintenance and monitoring, such as regular testing of leak detection systems, maintaining accurate inventory records, and maintaining spill buckets, which comes at a small fraction of the cost of clean-up activities to both the wallet and the environment.
Pollution prevention is just as important on an individual level. While the actions of one person may seem insignificant, the collective action of millions of individuals is monumental. In celebration of P2 Week, we’ve assembled 20 simple tips that we can all implement to minimize our environmental footprint.
Make sure your home is well-insulated and has energy efficient windows.
Use water-based paints and be sure to rinse paint brushes in the sink, where the water will eventually make its way to a wastewater treatment plant, and not outdoors, where the paint will end up in the groundwater.
Utilize LED lights instead of fluorescents, which may contain mercury. When disposing of fluorescent bulbs, be sure to take them to a certified collection center.
Plant trees. They help to keep the air clean.
Utilize recycled content plastic lumber for decks. Plastic lumber lasts far longer than wood lumber and requires no painting.
Do you have any other easy tips to prevent pollution? If so, share them in the comments. As Vincent Van Gogh said, “Great things are done by a series of small things brought together.” At Tata & Howard, each of us looks forward to creating a greener, healthier future by doing our individual, small part to decrease pollution. Happy Pollution Prevention Week!
The term “Lean” has become widely used in the manufacturing sector since the late 1980s when it was first used by James P. Womack, Ph.D. of MIT’s International Motor Vehicle Program to describe Toyota’s highly successful manufacturing process and business model. While its core premise of eliminating waste is quite simple, identification of waste and implementation of best practices takes effort. Waste can be defined as any process or activity without value — such as overproduction, defects, and waiting — and accounts for up to 60% of a typical manufacturing company’s production activities.
But Lean isn’t just for manufacturing companies. In fact, most companies can benefit greatly from incorporating Lean techniques into their standard operating procedures. At its core, Lean enables a business to run more efficiently by improving quality and reducing costs, whether that company is a car manufacturer, a hospital, a retail operation — or even a water or wastewater utility.
Key Principles
The Lean Enterprise Institute (LEI), long considered the premier resource for lean theory and training, identifies the five key Lean principles as value, value stream, flow, pull, and perfection. Value is always defined through the customer, and addresses such issues as price point, delivery timelines, requirements, and expectations. Value to a water or wastewater utility may include price, quality of water or effluent, reliability of service, and meeting regulatory requirements.
Once value has been established, each and every step and process taken to meet that value is mapped as the value stream. These steps include not only manufacturing processes, but also contributing areas and departments including administrative, human resources, and customer service. By mapping every step in the process, identification of areas lacking value can be identified and addressed. Value streaming results in not only less waste, but also improved operational understanding.
Flow refers to process efficiency and is the next step after waste was been eliminated from the value stream. Often, creating true flow requires cross-functionality across departments, something that can be a challenge for companies to implement. However, this step also boasts some of the highest efficiency gains. For water and wastewater utilities, increasing flow may include moving towards transparent communication between operators and management and standardization and documentation of processes and effective practice guidelines. Ensuring that the remaining steps in the process occur smoothly and without interruption is key to the lean process.
Reducing waste in the value stream and improving flow enables a manufacturing company to shorten the manufacturing process and implement “just in time” delivery, or pull. In service operations such as water and wastewater systems, pull focuses on the people and refers to the way in which work is distributed and managed. In a traditional push system, all projects and tasks are distributed as a giant to-do list, which can lead to disorganization, diluted priorities, and employees feeling overwhelmed. In a pull system, workers are allowed to pull in tasks as they are ready, leading to a more focused approach to projects, better prioritization of key initiatives, and increased communication between workers at all levels. Organizations that utilize a pull system for work realize a significant reduction in wasted time resulting in far more efficient time utilization.
The final step may actually be the most important: perfection. Perfection refers to continuous improvement by incorporating Lean thinking into the very fabric of the corporate culture. Perfection acknowledges that true Lean requires constant effort and is never static.
Lean Implementation
Because the main goal of Lean is to create more value with fewer resources, a Lean company strives to create an organization that provides perfect value with zero waste. In addition to changing from silo to matrix management, implementing Lean follows four basic tenets, known as the four Ps of Lean thinking: purpose, process, people, and performance.
Purpose
Companies must first determine their essential purpose. For some companies, profit may be the driving motivation, while others may exist for philanthropic purposes. Water and wastewater utilities provide an essential service to customers. Besides the general purpose of the organization, a company must also determine its philosophical drivers. These can include core values, mission, and vision.
Process
Once purpose has been determined, a company must determine the process by which it reaches its customer and produces the product, whatever that product may be. Simply put, process refers to the way in which a business operates in relation to its customer and its internal operations. Most of the key principles of Lean thinking can be applied during the process step. Unfortunately, it is also the step at which many businesses become stuck if they lose focus or lack cooperation from employees or management.
People
People refers not only to those for whom the product or service is created, but also the people within the organization who create the product or service. In other words, people are customers and employees, as well as some consultants and suppliers. Developing employees, growing leaders, improving management, and showing respect at all levels are important facets of this critical step.
Performance
Performance is the final step of the Lean approach and is in line with the perfection principle. A company must assess any improvement in its ability to deliver its product or service, and identify any additional gaps. Lean implementation typically goes through many trials and iterations before truly successful performance is achieved. Again, it is critical to remember that Lean is a continuous process that requires vigilance and ongoing effort from an organization.
Lean Thinking in Water and Wastewater Operations
Because it is often referred to as lean manufacturing, there is a misconception that Lean is strictly for manufacturing organizations. In fact, Lean is not a set of tactics or a simple method of cost reduction; rather, Lean is a completely different way of thinking and operating on an organization-wide basis.
For water and wastewater, Tata & Howard’s proprietary Business Practice Evaluation (BPE) is a highly effective methodology that can assist utilities in becoming lean organizations. By definition, a BPE is a “process that assesses the health of a utility’s business practices with the goal of minimizing the total cost of managing, operating, and maintaining utility assets while delivering exceptional service to customers” — the core definition of lean thinking. A BPE accomplishes this by assessing all business practices, identifying opportunities for improvement, and implementing a framework for a structured approach to managing, operating, and maintaining a utility in the same manner as a profitable business, where focus is placed on management of resources, employee engagement, operational efficiency, and customer service. The finished product provides a utility with a clear understanding of baseline history and areas of opportunity for improvement. In addition, the utility receives a matrix of recommendations for each business practice they want to improve, along with the risk and consequence of inaction. Organizations that have conducted a BPE significantly improve the operational efficiency of their utility. A BPE is arguably one of the most important steps in a water or wastewater utility’s journey toward becoming a truly Lean organization.
In Conclusion
All types of businesses across all industries and service offerings are turning toward Lean thinking to remain competitive and profitable in today’s consistently changing corporate climate. Successful Lean organizations recognize that lean is not a one-time cost reduction program or a quick fix, but rather a completely different way of thinking and operating that constantly evolves. While true Lean transformation takes long-term vigilance and attention, the benefits of increased operational efficiency, exceptional customer satisfaction, and better profitability are well worth the effort.
World Water Week is an annual event organized by the Stockholm International Water Institute (SIWI) that focuses on global water issues, and this year’s theme is “Water and Waste: Reduce and Reuse.” The main event takes place in Stockholm, Sweden where experts, innovators, stakeholders, and young professionals from various sectors around the globe will come together to share ideas, foster relationships, and develop innovative solutions to the world’s most urgent water-related problems. In 2016, over 3,300 individuals and over 330 organizations from 130 countries around the world participated in World Water Week, and the expectation is that 2017 will see at least those numbers. Through this year’s theme, World Water Week is focusing on two targets addressed by the Sustainable Development Goals (SDGs) of the UN’s 2030 Agenda for Sustainable Development including improving water quality and reducing waste by 2030 in order to help achieve sustainable development in a rapidly changing world.
Sustainable Development
Sustainable development is most commonly defined as development that meets the needs of the present without compromising the ability of future generations to meet their own needs. This means that we cannot meet our current needs at the expense or depletion of our natural resources. Degradation of water quality not only has a negative environmental effect, but also limits the water supply available for human usage. Therefore, we must develop and implement innovative solutions to improving water quality if we are to plan for a sustainable future. Fortunately, there exist easily implementable methodologies for improving water quality throughout the water environment.
Utilize mores sustainable water treatment technologies that limit environmental impact
Chemical additives have a significant impact on the health of the environment and its inhabitants. Implementing alternative treatment methodologies such as ozonation, ultraviolet radiation, and biological media helps to minimize the impact that water treatment has on our natural world, and protect our water supply for the future.
Minimize, and eventually eliminate, using drinking quality water for non-potable purposes
Producing drinking quality water utilizes a significant amount of energy, resources, and treatment chemicals, all of which have a negative impact on the environment. Minimizing the use of potable drinking water for other functions, including agricultural, industrial, and non-potable residential, helps to ease the burden placed on resources, the environment, and budgets.
Reduce lost water in municipal distribution systems
Communities lose millions of gallons of water each year to leaks in the distribution system. While replacing compromised pipes seems like an easy solution, the problem is actually much more complicated. Municipalities do not have sufficient funds to implement large-scale replacement projects; therefore, many compromised pipes remain in use, contributing to distribution system water loss. This loss results in reduced supply, which in turn forces some systems to seek alternate sources at a cost to both the environment and their budgets.
Conducting water audits and pipe condition assessments should be the first step towards efficient, cost-effective pipe replacement programs. Water audits help to identify the causes of water loss while developing strategies to reduce this loss, while pipe condition assessments provide insight into the quality and reliability of water distribution systems. Drinking water infrastructure in the United States, particularly in the northeast, is typically many decades-old, and deteriorating distribution systems can be a significant source of water loss through leakage. Effective water loss control programs reduce the need for facility upgrades and expansions, and in many instances, can reduce the need to find additional sources. In addition, a water loss control program can help protect public health by reducing the number of entry points for disease‐causing pathogens.
Incorporate stormwater best management practices into the built environment
Stormwater management traditionally meant infrastructure such as catch basins. Modern day stormwater management takes a much more holistic approach and maximizes the use of both the natural and engineered landscape. Some examples include onsite catchment and use, reduction of impervious surfaces, stormwater engineering such as bumpouts and tree boxes, and stormwater landscaping such as rain gardens and grassed swales.
Minimize stormwater pollution
Stormwater pollution occurs when precipitation picks up debris, trash, fertilizers, animal waste, pesticides, and improperly discarded chemicals as it moves over the ground. Reducing fertilizer and pesticide usage, cleaning up after pets, and ensuring that trash and chemicals are disposed of properly help to reduce the amount of contamination entering our waterways.
Reuse wastewater
After adequate treatment of wastewater to remove all pollutants and pathogens, it should be reused as much as possible. Treated byproducts can be used for fertilizer and methane fuel, and highly treated water can be reused for aquifer recharging, and even for drinking water.
And of course – educate!
Promote conservation, efficiency, and innovation in water use by incentivizing water conservation, implementing public outreach and education, and encouraging the adoption of methodologies and the usage of products that utilize the latest in water-efficient technologies.
In Conclusion
Achieving sustainable development is only achievable if we focus on the protection of our natural resources at every level. From improving treatment plant efficiency to installing WaterSense fixtures in our homes, creating a truly water wise future requires involvement from governments to individuals on a global level. Since 1991, World Water Week has served as a forum for legislators, scientists, experts, and interested parties to form partnerships and alliances, and to collaboratively find solutions to today’s most urgent water-related issues.
As those in the industry well know, water and wastewater treatment plants use an exorbitant amount of energy. In fact, 30-40% of total municipal energy consumption is due to water and wastewater treatment plants. In addition, energy currently accounts for 40% of drinking water systems’ operational costs and is projected to jump to 60% within the next 15 years. This excessive energy consumption places financial burden on already stressed water and wastewater utilities struggling to keep up with ever-increasing regulations and demand.
The Electric Power Research Institute (EPRI) conducted studies on wastewater treatment plants and cautions that as treatment requirements increase, energy requirements will also increase. EPRI also projects that as treatment requirements increase, the energy required to treat wastewater utilizing conventional technologies will increase exponentially. For example, new membrane bioreactor (MBR) processes actually consume 30-50% more electricity than plants that utilize more advanced treatment with nitrification. Also, plants that incorporate nanofiltration or reverse osmosis to meet stringent effluent utilize nearly twice the energy. EPRI further projects that strict nitrogen and phosphorus removal will be increasingly required, necessitating the incorporation of these energy-intensive technologies.
And let’s not forget the environment. Drinking water and wastewater systems add over 45 million tons of greenhouse gases annually, contributing to the already problematic issue of climate change. Bringing the issue full circle, climate change directly affects both the availability and the quality of our drinking water supply. The importance of incorporating energy efficiency into water and wastewater operations is paramount to these systems’ future sustainability.
Case Studies
Canaan, VT and Stewartstown, NH Shared Wastewater Treatment Plant Upgrades
The Towns of Canaan, Vermont and Stewartstown, New Hampshire operate a shared wastewater treatment facility, which required significant upgrades. The existing facilities were 40 years old and although a few upgrades were performed in the 90s, the facilities were not performing well, did not meet Life Safety codes, and required significant maintenance.
One of the primary elements of the design was the consideration of the economics of energy reduction. The design incorporated insulated concrete form construction for the building walls with R-49 insulation rating in the ceilings. The design also included a wood pellet boiler with a pellet silo and hot water heating system, which allowed for reduction of explosion proof heaters in the headworks building. All of the windows were low-E and highly insulated, and an outer glassed-in entry way increased the solar gain retention of the building and reduced heat loss. The process headworks and operations buildings were constructed as single story structures, increasing operator safety. The lagoon aeration system is now a fine bubble, highly efficient process with additional mixing provided by solar powered mixers that help reduce aeration requirements, improve treatment, and allows for the addition of septage, all at no cost due to solar power.
The pump station upgrades were designed to eliminate daily confined space entry by the operator by the conversion to submersible pumps. For sludge removal, a unique and simple “Sludge Sled” system was incorporated, which allows the operators to easily remove the sludge at their convenience. Sludge treatment is accomplished with a geo-bag system that allows the sludge to be freeze dried, reducing the volume by almost 50% with no energy consumption. The influent pump station was designed with three pumps instead of the normal two-pump system in order to meet both present and future design flows, allow for lower horsepower pumps, improve flexibility, reduce replacement costs, and reduce energy costs. The other four deep dry pit pump stations were converted to wet wells and submersible pumps, eliminating confined spaces, and are equipped with emergency generators, eliminating the need for operator attention when power is lost.
The incorporation of highly energy efficient building components resulted in reducing annual operation and maintenance costs, which resulted in a more sustainable facility. All of the equipment and processes were thoughtfully selected to reduce both annual and future replacement costs.
The treatment system is a 3-cell aerated lagoon system, and the solar powered mixers were installed to enable reduction of the aeration needs and horsepower during the summer months when septage is added. The aeration blowers, which are housed in insulated enclosures, reduce noise and were sized to allow for the addition of septage to the lagoons, which is not common in Vermont. The aeration blowers are controlled with Variable Frequency Drives (VFDs), which allow for greater operator control of aeration and provide energy cost savings. The operation is simple and safe for operators and others who need to maintain the facility and equipment. The design has provided flexibility to the operators and has resulted in an energy efficient, sustainable solution for this community.
Shrewsbury, MA Home Farm Water Treatment Plant Design
The Home Farm Water Treatment Plant (WTP) in Shrewsbury, Massachusetts was originally constructed in 1989. Although the WTP is still fully functional, its treatment capabilities are limited to chemical addition and air strippers for VOC removal, and the plant is capable of treating 6.0 million gallons per day (mgd). Manganese is present at all Home Farm wells, with widely varying levels from a low 0.03 parts per million (ppm) to a high 0.7 ppm. The existing treatment plant sequesters manganese, but does not have the ability to remove it from finished water.
Three treatment methodologies were piloted. The first two were greensand and pyrolucite, both commonly implemented catalytic media options for removing manganese and iron. The third was Mangazur®, a new technology. Mangazur® filter media contains the microscopic organism leptothrix ochracea, which consumes manganese and is naturally occurring in groundwater. Through consumption, the microbes oxidize the manganese to a state where it can precipitate onto the media. Unlike other media, Mangazur® does not require regeneration due to the continuous growth of microbes within the filter. Mangazur® technology also does not require chemical addition for pre-oxidation, minimizing the amount of chemical required for the plant.
Pilot testing for the biological treatment was performed over five one-week trials. Test parameters included a long shut-down on the filters, adding pre-oxidant, and adjusting pH or dissolved oxygen. The results of the testing indicated that although the Mangazur® does require a correct dissolved oxygen level and pH, it does not require a pre-oxidant, making the only chemical addition necessary for pretreatment potassium hydroxide for pH adjustment. Filter backwash efficiency is also a major benefit of the Mangazur® technology for the Home Farm application. With loading rates twice that of traditional catalytic media and filter runs exceeding 96 hours, the Town would only need to backwash the four filters once every four days rather than eight filters every day, saving a significant amount of water. The backwash flow rate and duration are also significantly lower for Mangazur® filters than for other traditional filter options. The results of the pilot tests indicated that all technologies were viable options to reduce manganese levels below 0.05 ppm; however, the biological treatment was the most efficient option.
Since the existing chemical feed equipment in the plant is aging and the existing building itself was also in need of rehabilitation, the decision was made to construct an entirely new standalone 7.0 mgd facility. The new facility will feature many energy efficient features including translucent panels for lighting efficiency, high efficiency water fixtures, high efficiency lighting, and stormwater bioretention areas for drainage. In addition, while the existing building will be demolished, the concrete slab slab will be kept for future installation of solar panels. The new facility also contains three deep bubble aerators for VOC removal. While Mangazur® technology has been approved in one other municipality in Massachusetts, there are few treatment plants in the northeast using this technology, and of those treatment plants, none have a design capacity above 5.0 mgd. Home Farm has a much higher design capacity and will be the largest Mangazur® water treatment plant in the northeast once completed. The Mangazur® filters at Home Farm will have the second highest design capacity in the country, after a 26.0 mgd treatment plant in Lake Havasu City, Arizona.
Tata & Howard provides on-call engineering services for water, wastewater, and energy related projects for the City of Flagstaff, Arizona. Several options for replacement of the blowers were evaluated and presented to the City in a report that recommended the installation of appropriately sized turbo blowers and upgrading the controls logic to automate dissolved oxygen controls.
The City had been experiencing long term maintenance issues with the existing biogas piping at the Wildcat Wastewater Reclamation Facility. The piping to the co-generator was not providing an adequate supply of gas from the digesters which, if operating, could save the City approximately $200,000 in annual power costs. The goals of this project were the restoration of the ability to run the generator on biogas, utilize the heat generated by the sludge digestion process to further reduce energy costs, reduce maintenance time to operate the biogas system, and have a positive impact on the environment, since methane is one of the most potent greenhouse gases.
In addition, Tata & Howard conducted an energy efficiency study on the aeration blowers and pumps at two treatment plants. Pumping systems had efficiencies as low as 20%. Pumps and blowers were oversized to meet peak and future demands but not efficient at low flows or off peak flows. The testing showed that modifications to these systems had the potential to save the City approximately $250,000 in annual electrical costs and $445,000 in APS rebate funds for the modifications.
While these three case studies are all extremely different projects, the goals are the same: increased energy efficiency, greener operations, and sustainability, all while meeting project objectives, budgets, and deadlines. Increasing energy efficiency in water and wastewater treatment is no longer optional; rather, it is a necessity to remain operational by meeting both budgetary and sustainability objectives. By incorporating innovative thinking and tailored methodologies into rehabilitation and repair projects, water and wastewater systems can ensure sustainable operations and a greener environment while protecting our world’s most precious resource for generations to come.
When communities grow and expand, utilities must do the same while keeping up with quality and regulatory requirements. With aging infrastructure and limited capital dollars, utilities must find alternative ways of funding crucial projects. Fortunately, several state and federal agencies realize this pressing issue and are collectively helping utilities and private organizations procure the resources they need. While making decisions on which projects and issues to be addressed first may be challenging, acquiring the capital to complete these projects is available – if you know where to look.
Drinking Water State Revolving Fund (DWSRF)
The EPA’s DWSRF can be used for infrastructure improvements in drinking water systems. The DWSRF emphasizes funding to small and economically disadvantaged communities, allowing them to finance improvements needed to comply with the Safe Drinking Water Act and to address the most serious risks to human health. The DWSRF authorizes the EPA to make grants to states each year to which each state must match 20% of its grant and develop intended use plans indicating how the allotted funds will be used. The six categories of projects that are eligible to receive DWSRF assistance include the following:
Treatment: Projects to install or upgrade facilities to improve drinking water quality to comply with SDWA regulations.
Transmission and Distribution: Rehabilitation, replacement, or installation of pipes to improve water pressure to safe levels or to prevent contamination caused by leaky or broken pipes.
Source: Rehabilitation of wells or development of eligible sources to replace contaminated sources
Storage: Installation or upgrade of finished water storage tanks to prevent microbiological contamination from entering the distribution system.
Consolidation: Interconnecting two or more water systems.
Creation of New Systems: Construction of a new system to serve homes with contaminated individual wells, or consolidation of existing systems into a new regional water system.
Public water systems are eligible to receive DWSRF assistance if they have the capacity to ensure compliance with the Safe Drinking Water Act or meet certain conditions to return to compliance. Systems owned by federal agencies are not eligible.
Clean Water State Revolving Fund (CWSRF)
The CWSRF program is a federal-state partnership with the EPA that provides communities a permanent, independent source of low-cost financing for a wide range of water quality infrastructure projects. The EPA provides grants to all 50 states plus Puerto Rico to capitalize state CWSRF loan programs. These programs function like environmental infrastructure banks by providing low interest loans to eligible recipients for high priority water quality activities. Projects that are eligible for DWSRF funding include the following:
CWSRF funding for public, private, and nonprofit entities:
National Estuary Program Projects: Development and implementation of a conservation and management plan
Nonpoint Source: Implementation of a state nonpoint source pollution management program
Stormwater: Measures to manage, reduce, treat, or recapture stormwater or subsurface drainage water
Decentralized Wastewater Treatment Systems: Construction, repair, or replacement of decentralized wastewater treatment systems that treat municipal wastewater or domestic sewage
Watershed Pilot Projects: Development and implementation of watershed projects
Security Measures at Publicly Owned Treatment Works: Measures to increase the security of publicly owned treatment works
Water Reuse: Projects for reusing or recycling wastewater, stormwater, or subsurface drainage water
CWSRF funding for municipalities, inter-municipal, interstate, or state agencies
Water Conservation, Efficiency, and Reuse: Measures to reduce the demand for publicly owned treatment works capacity through water conservation, efficiency, or reuse

Energy Efficiency: Measures to reduce the energy consumption needs for publicly owned treatment works
CWSRF funding for qualified nonprofit entities:
Technical Assistance: Provide technical assistance to owners and operators of small and medium sized publicly owned treatment works to plan, develop, and obtain financing for CWSRF eligible projects and to assist each treatment works in achieving compliance with the CWA.
Water and Environmental Programs (WEP)
USDA Rural Development provides funding for the construction of water and waste facilities in rural communities and also provides funding to organizations that provide technical assistance and training to rural communities in relation to their water and waste activities. WEP is the only Federal program exclusively focused on water and waste infrastructure needs of rural communities with populations of 10,000 or less. WEP is administered through National Office staff in Washington, DC, and a network of field staff in each State. Types of grants offered by WEP funding include the following.
Emergency Community Water Assistance Grants: Helps eligible communities prepare for, or recover from, an emergency that threatens the availability of safe, reliable drinking water for households and businesses. Emergencies include drought or flood; earthquake; tornado; hurricane; disease outbreak; chemical spill, leak, or seepage; or other disasters.
Water & Waste Disposal Loan & Grant Program: Provides funding for clean and reliable drinking water systems, sanitary sewage disposal, sanitary solid waste disposal, and stormwater drainage to households and businesses in eligible rural areas. This program assists qualified applicants that are not otherwise able to obtain commercial credit on reasonable terms.
Water & Waste Disposal Predevelopment Planning Grants: Assists low income communities with initial planning and development of an application for USDA Rural Development Water and Waste Disposal direct loan/grant and loan guarantee programs.
Community Development Block Grant (CBDG)
CDBG funds are generally used for long-term community needs, including mitigation. Beginning in 1974, the CDBG program is one of the longest continuously run programs at the Department of Housing and Urban Development (HUD). The CDBG program provides annual grants on a formula basis to 1209 general units of local government and States. Utilities can use these grants to buy, construct, or fix public facilities such as water and sewer systems. They can also match FEMA grants. Grantees may fund activities that meet urgent community development needs. CDBG funds may be allocated for many different activities including the following:
Construction or reconstruction of water and sewer facilities, streets, and other public works
Relocation and demolition
Rehabilitation of public and private buildings
Planning activities
Activities relating to energy conservation and renewable energy resources
Public Works Program
The U.S. Economic Development Administration’s (EDA) Public Works Program helps distressed communities revitalize, expand, and upgrade their physical infrastructure. This program enables communities to attract new industry, encourage business expansion, diversify local economies, and generate or retain long-term, private-sector jobs and investment through the acquisition or development of land and infrastructure improvements needed for the successful establishment or expansion of industrial or commercial enterprises. EDA invests in public works projects, including water and sewer systems improvements, that meet the following criteria:
The project’s demonstrated alignment with at least one of EDA’s current investment priorities
The project’s potential to promote job creation and private investment in the regional economy
The likelihood that the project will achieve its projected outcomes
Ability of the applicant to successfully implement the proposed project, including financial and management
OF NOTE: Funding Programs Targeted by Trump’s FY18 Budget
Trump’s proposed FY18 budget includes deep cuts to the nation’s major infrastructure programs. Both the DWSRF and CWSRF, funded by the EPA, are slated for drastic reduction under Trump’s budget, while the CBDG program is marked for elimination. In fact, Trump’s budget proposes to completely eliminate 66 federal programs including not only CBDG but also the United States Department of Agriculture’s Rural Water and Waste Disposal Program, and the Northern Border Regional Commission, which is a Federal-State partnership for economic and community development within the most distressed counties of Maine, New Hampshire, Vermont, and New York. Without these funding programs, some communities may not be able to implement needed system improvements.
In Conclusion
Utilities face an uphill battle when it comes to keeping their distribution systems up to date and running efficiently. Both public and private entities are seeing the increase in demand outpacing capital, threatening crucial projects. Fortunately, state and federal funding is available to help alleviate the financial burden facing many communities, while capital efficiency planning helps communities prioritize projects. Sufficient funding and planning today can assure efficiency and deliverability for future generations.
