The Proposed 2018 Budget Cuts Require Water Systems to Practice Capital Efficiency

In recent years, water systems have been faced with challenges that are unique to modern times. Our nation’s buried infrastructure is reaching a critical juncture in that it is nearing or has reached the end of its useful life, or is in dire need of replacement due to the presence of lead. At the same time, climate change is affecting supplies, while a burgeoning population is creating a larger demand. And as we increase our knowledge about the dangers of additional contaminants in our drinking water, utilities are saddled with increased regulations that require strict compliance by specific deadlines. Obtaining compliance often requires extensive upgrades or completely new infrastructure, all of which come with a high price tag.

And therein lies the problem. While water systems are facing such a complex set of challenges that require significant expenditure, available capital is quickly drying up. Water systems are seeing their budgets slashed while operations and maintenance costs soar. In addition, funding sources have been dwindling, and President Trump’s 2018 budget aims to slash them even further. In fact, Trump’s proposed 2018 budget completely eliminates the United States Department of Agriculture (USDA) Rural Development Water and Waste Disposal Loan and Grant Program. This 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 rural areas who are not otherwise able to obtain commercial credit on reasonable terms.”1 In other words, lower income rural communities who fully rely on USDA Rural Development grants to fund their water system improvements will no longer have a source of federal funding.

The proposed 2018 budget also budget cuts the Environmental Protection Agency (EPA) by 31%, or $5.7 billion. The EPA provides funding to water systems through its Drinking Water State Revolving Fund (DWSRF) and Clean Water State Revolving Fund (CWSRF) programs, both of which “provide communities a permanent, independent source of low-cost financing for a wide range of water quality infrastructure projects.”2 Considering that almost all spending on critical infrastructure such as drinking water, wastewater, and transportation is provided by the public sector, these cuts are expected to make a huge impact on available funding for critical water infrastructure projects.

Because working capital is becoming so scarce, it is critical that water systems manage their assets with an eye on efficiency and systematic planning. Asset management is arguably one of the most important strategies for effectively maintaining utilities today and critical to the health and maintenance of water systems. Key components of a utility asset management plan include performing an inventory and condition assessment of the system’s assets, defining level of service goals, identifying critical assets, establishing life cycle costs, and developing a long-term funding strategy. In other words, a successful asset management plan requires a thoughtful, systematic approach that provides for the rehabilitation and replacement of assets over time, while also maintaining an acceptable level of service for existing assets.

Advanced condition assessment for pipeline rehabilitation provides insight into the quality and reliability of a water distribution system.

Today’s stringent budgets demand precise efficiency and cost-effectiveness, and determining which assets should be prioritized can be a challenge. It is no longer economically feasible to create an asset replacement schedule based solely on life cycle and critical components; rather, utilities today must pinpoint assets that are most in need of repair or replacement in order to stretch existing capital and justify new budget requests.

Capital efficiency planning helps to do just that.  Our proprietary Capital Efficiency Plan™ (CEP) methodology combines the concepts of asset management, hydraulic modeling, and system criticality into a customized, comprehensive report that provides utilities with a roadmap for future repair and replacement. The report includes database and GIS representation for each pipe segment within their underground piping system, prioritizes water distribution system piping improvements, and provides estimated costs for water main replacement and rehabilitation. Because each water system has unique characteristics and challenges, our CEP includes a workshop with knowledgeable field staff and managers for each project that helps to fill in data gaps, correct incorrect records, and identify specific issues and critical components that are custom to the system. The results of the workshop provide significant value by improving the quality of the asset data and the accuracy of the hydraulic model. Because the CEP utilizes a highly structured, detailed, and targeted approach, utilities can confidently justify the costs of repairing or replacing those assets most in need of repair or replacement when preparing annual budgets. Our CEPs have assisted numerous utilities throughout New England by providing a practical and easily understandable plan to critical asset repair and replacement, as well as an advantage when it comes to procuring funding.  The same approach can be applied to above ground assets as well as wastewater and stormwater systems.

Land that was once covered by water from the lake is now exposed.

Increasing regulations, climate change, shrinking budgets, dwindling supply, and population growth — these are all challenges that affect the financial capacity of today’s utilities. And with the proposed budget cuts under the Trump administration, water systems will feel even greater fiscal pressure. Competition for SRF funding will intensify, and utilities will be required to definitively justify the reason for their funding request. By combining asset management with hydraulic modeling and system criticality, our Capital Efficiency Plans™ can help utilities to maintain the health and viability of their water systems today so that they can continue to provide safe, clean drinking water tomorrow, and well into the future.

Infrastructure Week 2017 — #TimeToBuild

There are few – very few – issues that have as much bipartisan support today as investing in our nation’s infrastructure. We all have experienced dodging potholes while we drive, waiting for a bus that feels like it is never going to come, or being packed like sardines in an overcrowded airport for an interminable amount of time. We have all read the stories about the drinking water crisis in communities with neglected pipes, and seen the news coverage of gas pipeline explosions or levees that break during a flood. Infrastructure affects every single American. We all rely on it, and we all know it is time to build something better.

Roads, bridges, rails, ports, airports, pipes, the power grid, broadband — it is all infrastructure. It affects our daily commutes and our summer vacations. Infrastructure determines if we can drink water straight from our taps and flush our toilets. It brings electricity in to our homes and factories. For decades, the country let deferred maintenance bills pile up and looked the other way while other countries invested significantly more in everything from ports to airports, and from roads to rails. But there has been an awakening about the urgency of this issue, and more Americans support investing in our infrastructure than nearly any other issue right now. All we need is a little political courage out of Washington, D.C. to make this idea a reality.

That is why Tata & Howard is participating in Infrastructure Week 2017. We’re joining hundreds of organizations across the country this week, all raising awareness about this critical issue.

Every year America fails to adequately invest in our infrastructure, the United States becomes less competitive, our economy grows more slowly, and families and businesses lose valuable time and money. The goods we manufacture cost more when they get stuck on congested highways, rerouted around structurally deficient bridges, and stranded at outdated ports. World War II era radar technology and airports at capacity deter U.S. consumers from travelling, annually robbing the economy tens of billions of dollars.

Decades of underfunding and deferred maintenance have pushed our country to the brink of a national infrastructure crisis. We are desensitized to tragedies as though they are normal. Fatal mass transit accidents, toxic drinking water, bridges collapsing, and rivers contaminated with raw sewage are all actually completely preventable and we, as a nation, should declare them unacceptable.

It is time to say “enough.” We can build something better than this. There are examples around the country and the world that show us that it is entirely possible to build something better than this. During Infrastructure Week, we also want to recognize progress. We want to see more partnership and investment going forward. It is the only way to build us out of this hole.

Closing our country’s trillion-dollar infrastructure investment gap demands a strong federal partner to fund large and transformative projects. We are going to need collaboration between the public and private sectors to create innovative solutions. And leaders at all levels need to commit to building a long-term, sustainable plan to invest in America’s infrastructure.

Tata & Howard Celebrates Working Moms This Mother’s Day

Some of Tata & Howard’s working moms

Far more men than women traditionally pursue careers in STEM — science, technology, engineering, and math — and the field of engineering has long been male-dominated. In the early 1980s, only about 5% of engineers in the United States were women, and while that number has improved slightly, it still has a long way to go. Currently, about 14% of engineers and about 18% of engineering college students are women. And, according to the United States Census, those female engineers earn approximately 83% of what their male counterparts earn.

Not so at Tata & Howard. Since the firm’s inception in 1992, Tata & Howard has recognized and rewarded the value of female engineers. Nearly half of the firm’s initial 20 hires were female, and that trend has continued. Today, 34% of our engineering force is female, and about 20% of our total staff are working moms, including our two Co-Presidents, Karen Gracey, P.E. and Jenna Rzasa, P.E. In addition, we place great value on our support staff, many of whom are working moms. This Mother’s Day, we’d like to introduce you to our amazing working moms.

The High Cost of High-Hazard Dams

ASCE-report-cardIt is well known that our nation’s infrastructure is in desperate need of repair or replacement. In fact, the American Society of Civil Engineers (ACSE) 2017 Report Card has given our country’s infrastructure an overall grade of D+. Dams are a part of that critical infrastructure, and they have received an abysmal D grade from ASCE. We have over 90,000 dams in our country, and the average age of these dams is 56 years old. Considering that dams built 50 years ago were not designed for current standards and usually have inadequate spillway capacity, these numbers are concerning.

Even more alarming, America has nearly 15,500 high-hazard dams, with over 2,170 of these being deemed deficient. A dam is rated high-hazard when dam failure could result in the loss of human life, and deficient when it is at serious risk of failure. A deficient, high-hazard dam is a tragedy waiting to happen. Also, considering the estimated cost to repair these deficient, high-hazard dams is almost $45 billion, it is apparent that we have a dam crisis on our hands.

About Dams

Lake Mead, impounded by the Hoover Dam, is one of the most popular vacation spots in the country.

Dams provide significant economic and social benefits to society, including flood control, water storage, irrigation, debris control, and navigation. In addition, around 3% of our nation’s dams provide hydroelectric power — a clean, renewable energy source — accounting for 35% of our country’s renewable energy and 10% of our total power needs. And, of course, the most frequent function of dams is recreation. Dams impound eight of the top ten most popular vacation lakes in the United States, accounting for millions of tourist dollars and some of our country’s most beautiful and enjoyable areas.

mill-river-dam-flood
The Mill River Dam collapse was the first manmade dam disaster and one of the worst of the 19th century. On May 16, 1874, the Mill River Dam in Williamsburg, MA failed, killing 139 people and wiping out four towns in western Massachusetts within one hour.

Catastrophic dam failures have occurred in the United States for well over a century, resulting in the deaths of thousands of people and causing millions of dollars in damages. This year, we narrowly avoided a disaster when California’s Oroville Dam stabilized after threatening to fail. During the crisis, over 188,000 people were displaced due to mandatory evacuations of the area. Although the Oroville Dam crisis thankfully ended without loss of life, the cost to repair the spillway is estimated to be $275 million. In 2003, the Silver Lake Dam in Michigan failed, causing approximately $100 million in property damages and putting over a thousand miners out of work. In 2004, the Big Bay Lake Dam in Mississippi failed, destroying 48 homes and seriously damaging 53 others. In 2006, the Ka Loko Dam in Hawaii failed, killing seven people and releasing nearly 400 million gallons of water, causing significant property and environmental damage.

High-hazard dams are cause for concern in every state in the nation. In Massachusetts, 1,453 dams are included in the National Inventory of Dams, 333 of which are high-hazard. Of those, about 50 are classified as “poor” or “unsatisfactory” and in urgent need of repair. If any of these dams were to fail, there is a high likelihood that there would be a loss of human life. Dam failure is most frequently caused by overtopping, accounting for 34% of all dam failures. Causes of overtopping include inadequate spillway design, blocked spillways, settlement of the dam crest, and floods exceeding dam capacity. Other causes of dam failure include foundation defects such as slope instability and settlement (30%); piping, resulting in internal erosion caused by seepage (20%); and other causes including structural failure of materials, settlement and resulting cracking, poor maintenance, and acts of sabotage (16%).

Safety Programs

oroville-dam-damage

The National Dam Safety Program (NDSP) was signed into law in 1996. NDSP was established to improve safety and security around dams by providing assistance grants to state dam safety agencies to assist them in improving their regulatory programs; funding research to enhance technical expertise as dams are built and rehabilitated; establishing training programs for dam safety inspectors; and creating a National Inventory of Dams. Every state in the nation excepting Alabama has a dam safety program, and 41 states also have Emergency Action Plan (EAP) requirements. A detailed and up-to-date EAP is critical to a successful dam safety program for high-hazard and significant-hazard dams. States without EAP requirements are Alabama, Georgia, Illinois, Iowa, Kentucky, North Carolina, Vermont, Wyoming, and — believe it or not — California.

Unfortunately, about one-third of our nation’s high-hazard dams lack an EAP. In addition, state dam safety programs are sorely underfunded and understaffed, and many of our nation’s deficient dams are not being repaired or rehabilitated in a timely manner. Why? State dam safety programs provide the inspection, permitting, recommendations, and enforcement authority for 80% of our nation’s dams, yet the average ratio of dams to dam safety inspectors is 207:1. Also, about two-thirds of our nation’s dams are privately-owned. Without enforcement of repair recommendations, some dam owners simply choose not to sink any money into their deficient dam.

kaloko-dam
The Ka Loko Dam breach in Hawaii resulted in the deaths of seven people, including a pregnant woman and a toddler.

For example, the Ka Loko Dam in Hawaii was privately-owned, and owner James Pflueger was sentenced to seven months in prison in exchange for a plea of no contest to reckless endangering. By entering the plea, prosecutors agreed to drop the seven counts of manslaughter. But admittedly, the dam failure was the result of a series of negligent events. The State of Hawaii, like most states in the nation, had a shortage of dam inspectors, and the Ka Loko Dam had not been adequately inspected. Also, Pflueger performed unpermitted construction activities at the dam, including grading and filling in the spillway. The County of Kauai ordered Pflueger to cease and desist all illegal grading operations, yet Pflueger ignored the order with help from then-Mayor Maryann Kusaka, who served as mayor of Kauai from 1997-2004. He also knew that there was seepage at the dam prior to the failure.

Key Issues 

The Wachusett Dam in Clinton, MA is a high-hazard dam, rated in satisfactory condition.

Clearly, the Ka Loko Dam failure was due to gross negligence and was completely avoidable. To avoid similar tragedies in the future, all of the key issues facing our nation’s dams should be addressed. First and foremost, our country needs to invest in infrastructure and to prioritize funding of dam safety programs. It is imperative that dam safety agencies have adequate personnel and resources to enforce inspection, repair, and rehabilitation recommendations. Also, since two-thirds of our nation’s dams are privately-owned, lack of funding for private dam upgrades is a huge problem. Adequate maintenance and rehabilitation of dams is costly, ranging from thousands to millions of dollars, and many private owners simply cannot afford these costs. Because of the high risk of high-hazard dams, our nation must prioritize funding assistance and loan programs to both public and private owners. It is also crucial that high-hazard dams have an up-to-date EAP, including action plans as well as notification and evacuation procedures, so that authorities are prepared and residents living downstream of the dam are protected. And speaking of residents, public outreach and awareness may be the most critical component of dam safety and awareness. The typical American citizen has no understanding of the role that dams play in our lives, or of the devastation that could come about from a dam failure. Even developers and officials are often in the dark about dams in their own communities. And, of course, everyone needs to understand that all high-hazard dams, no matter how seemingly structurally sound, are potentially dangerous and that there is inherent risk living in a dam break flood-prone area. Also, many of the private dam owners in our country are largely unaware of both their responsibility toward residents and businesses located downstream of their dam and of proper dam maintenance and repair procedures.

In Conclusion

We must change the way we manage our nation’s dams in order to prevent future catastrophes. The recent Oroville Dam crisis should serve as a warning to residents and legislators. As our dams age and climate change increases severe weather events, we must invest in the oversight, funding, and awareness of this critical infrastructure. Until we do, events such as the Oroville Dam crisis and the Ka Loko Dam failure may occur with increasing frequency, resulting in loss of life, environmental damage, and economic disaster.

Earth Day 2017

earth-day-2017Earth Day is celebrated by over one billion people globally on April 22 each year. Credited as being the catalyst for the modern environmental movement, Earth Day was first celebrated in the United States in 1970. The Clean Air Act was passed later in 1970, the Clean Water Act in 1972, and the Endangered Species Act in 1973. Earth Day went global in 1990, and has since become the world’s largest global observance, celebrated in over 192 countries.

T&H employee-owners participated in the 17th Annual Earth Day Charles River Cleanup in 2016, and we will again be participating in 2017.

Earth Day serves as a reminder for all of us to make small changes in our daily lives to improve our environment. Whether eliminating disposable cup usage or practicing water conservation, simple changes can make a huge impact when implemented on a global scale. At Tata & Howard, we do our part by having a dedicated Green Committee that is focused on making our offices as environmentally friendly as possible through small changes, such as eliminating disposable flatware and cups and providing reusable water bottles to all employee-owners. We also actively participate in environmental events such as the Charles River Cleanup in Boston, MA, taking place this year on April 29.

Earth Day is also an opportune time to reflect on the impact of our work. Here at Tata & Howard, improving our environment is an integral part of virtually everything we do. Tata & Howard was founded in 1992 as a water engineering consulting firm, and providing innovative solutions for water supply, treatment, and distribution has been a primary focus since that time. Over the years, sustainability has also become of key importance, ensuring that our local communities have a safe, clean water supply for generations to come.

wastewater-treatment-plant
The design of the Canaan, VT/Stewartstown, NH wastewater treatment plant includes several green features.

In 1997, we started providing wastewater engineering consulting services as well. Since that time, wastewater treatment has changed and improved to the point that wastewater has even been utilized for direct potable reuse. Energy efficiency and sustainability in wastewater treatment operations are now paramount, as are green energy solutions. We are committed to incorporating options that are both efficient and environmentally friendly, as well as being cost-effective. We recently completed a wastewater treatment plant upgrade project in Vermont that included several green and sustainable features, including VFDs and solar panels, and the project won an ACEC/VT Excellence in Engineering Merit Award earlier this year.

T&H provides UST removal services.

In 2011, we added an environmental services division to Tata & Howard and have since worked on countless projects solely aimed at cleaning up our environment. In implementing these response actions, we also strive to eliminate or reduce total energy use, air pollutant emissions, greenhouse gases, water use, materials consumption, and ecosystem and water resources impacts. These projects include VOC removal, in-situ soil and groundwater treatment, offsite soil recycling and reuse, brownfield remediation, and underground storage tank (UST) closure and removal. Our remedial actions at these properties remove toxins from our soil and water, eliminate toxic vapors from affecting indoor air quality, and help to make our world a safer, greener place. We also provide stormwater services, including NPDES MS4 permit compliance as well as Low Impact Development and Best Management Practices. All our stormwater services help to reduce the harmful impact that stormwater runoff has on the environment.

Earth Day is the perfect time to assess the impact of our personal habits on the environment, as it is also a time to think about the value of our profession. As our business continues to grow, we will enhance our capabilities with services that improve our environment and increase sustainability. At Tata & Howard, every day is Earth Day, and we are proud of the work that we do to protect our natural world.

Happy Earth Day!

Benefits of Unidirectional Flushing (UDF) Infographic

Unidirectional flushing (UDF) is a unique process utilized to maintain a distribution system as well as learn critical information about the system. An effective UDF program should be conducted annually, at a minimum. Check out our UDF infographic that shows the benefits of UDF over conventional flushing:

Climate Change and Stormwater: The Perfect Storm

stormwater-runoffStormwater runoff is a concern year-round, but even more so in the spring when snow is melting and rain is abundant, particularly in humid continental climates. Stormwater starts as precipitation such as snow, sleet, and rain, which lands on natural ground cover such as forests, grass, or gardens. In a natural environment, stormwater soaks into the ground and is filtered by layers of dirt and rock, then finds its way to our groundwater and drinking water supply. Due to urbanization, stormwater in developed areas does not land on natural ground cover but instead washes off roads, driveways, parking lots, rooftops, and other impervious surfaces, becoming stormwater runoff. Stormwater runoff picks up road salt, chemicals, oil, bacteria, sewage, sediment, and garbage, then washes these pollutants into ditches and storm drains, contaminating our streams, rivers, ponds, and lakes. To make matters worse, climate change exacerbates stormwater runoff and contributes greatly to the impairment of surface water supplies.

How Climate Change Exacerbates Stormwater Runoff

flash-flood-stormwater
Climate change will likely bring more intense storms to all areas of the country.

A study by scientists from the National Center for Atmospheric Research in Boulder, Colorado published in December 2016 indicates that climate change will likely bring more intense, frequent, damaging storms to all areas of the country, particularly to the Northeast and the Gulf Coast. In fact, studies show that storms in these areas could become up to five times as frequent and bring 70% more rain if greenhouse gas emissions are not reduced. Storms of this magnitude will likely cause flash floods, landslides, and an overabundance of stormwater runoff – far more than current municipal stormwater systems are designed to handle.

California has recently been experiencing severe drought combined with intense storms.

The study also indicated that regions such as the Pacific Northwest and central United States will likely become drier, but with more intense, extreme rainfall. We have already seen this in northern California, where the Oroville Dam suffered serious damage after drenching rains in February. Prior to these rains, the state had been plagued by severe drought. Rising temperatures increase atmospheric humidity, causing extreme precipitation and an increased risk of flash flooding. And while it may seem counterintuitive, drought only intensifies the problem. Drought leads to less vegetation and more firmly packed soil, both of which inhibit infiltration. When heavy rains follow drought, soil tends to erode, washing remaining plants away as well. Regular, gentle rain is the key to restoring soil, and without it, soil degradation will only intensify.

Managing Increased Stormwater Runoff

Unfortunately, the above-mentioned factors will likely lead to an increase in stormwater runoff and its accompanying problems. Municipal stormwater systems, already faced with increased nutrient regulations, will likely become overwhelmed, resulting in backups, localized flooding, and increased runoff of contaminants such as bacteria and nutrients into waterways.  Also, combined stormwater and wastewater systems overwhelmed by extreme precipitation will release more combined sewer overflows (CSOs) into our rivers, lakes, and streams, degrading water quality and affecting aquatic life. At the same time, drought exacerbates the problem by lowering water levels, leading to more concentrated levels of pollutants in our waterways. These combined factors cause water quality deterioration and create major problems for water treatment plants. Already facing dwindling budgets, municipalities will have difficulty meeting water quality standards if stormwater runoff continues to increase unabated.

Fortunately, successfully managing stormwater runoff is a realistic goal with proper planning and incorporation of best management practices (BMPs). Systems that proactively develop strategies to address stormwater runoff will find themselves far better prepared to manage both increased stormwater and more stringent regulations. Stormwater management strategies include the following:

  1. Rain gardens are a beautiful and sustainable way to manage stormwater.

    Increase the use of Low Impact Development. Low Impact Development (LID), also known as green infrastructure, is a stormwater management approach that maintains natural hydrology during site development. LID minimizes impervious surfaces and utilizes existing natural site features along with conservational controls to manage stormwater. Examples of LID design include bioretention basins, grassed swales, and rain gardens.

  2. Minimize impervious surfaces. Impervious surfaces such as roads, parking lots, and rooftops prevent infiltration. Install pervious pavements on driveways and walkways, stormwater bumpouts on streets, and tree boxes on sidewalks. Also, disconnect impervious surfaces by installing grass or gravel buffer zones. Lastly, plant green roofs and roof gardens to greatly reduce stormwater runoff while enhancing the environment.
  3. Protect and create wetlands. Wetlands are of great value due to their ability to retain water and recharge groundwater. Constructed wetlands provide the same benefit as natural wetlands and help to mitigate water pollution.
  4. White clover is native to New England, drought resistant, and soft under the feet.

    Landscape with native flora. Native trees and plants provide habitat for and attract birds, butterflies, and other beneficial local wildlife, and are acclimated to local rainfall amounts and climate. Unlike turf grass, native plants require very little maintenance because they are naturally resistant to local pests and disease. Because they do not need fertilizers, pesticides, or supplemental watering, they are easy and inexpensive to maintain and are environmentally friendly.

  5. Plant trees. Trees help to manage stormwater by reducing erosion and runoff along streams and waterways. They also help to cool urban areas and improve the air quality.
  6. Separate combined sewer overflows. By separating the collection of sewage and stormwater, overflow of sewer systems and treatment plants during rainy periods prevents the mixing of the surface runoff, which is lightly polluted, with municipal wastewater, which is highly polluted.


In Conclusion

Climate change and stormwater runoff together create the perfect storm for water quality degradation. We are already seeing the effects of climate change on our nation’s infrastructure, and unless we address these complications now, we will likely find ourselves increasingly burdened by boil water orders and expensive water treatment projects. Fortunately, by proactively making some simple and largely inexpensive environmental improvements, we can protect our nation’s water bodies for future generations.

Fix a Leak Week 2017

Fix-a-leak-week
The Facts on Leaks

March 19-25 is Fix a Leak Week 2017.

Fix a Leak Week is celebrated in March of each year as a time to remind Americans to check their household fixtures and irrigation systems for leaks. In addition, it is a good time to address the leaks that we cannot see — those in our underground infrastructure. By addressing leaks in our homes and in our water systems, we can help to save our world’s most precious resource.

Leaks in the Home

  • The average household’s leaks can account for more than 10,000 gallons of water wasted every year, or the amount of water needed to wash 270 loads of laundry.
  • Household leaks can waste more than one trillion gallons annually nationwide. That’s equal to the annual household water use of more than 11 million homes.
  • 10% of homes have leaks that waste 90 gallons or more per day.
  • Common types of leaks found in the home include worn toilet flappers, dripping faucets, and other leaking valves. All are easily correctable.
  • Fixing easily corrected household water leaks can save homeowners about 10%  on their water bills.
  • Keep your home leak-free by repairing dripping faucets, toilet flappers, and showerheads. In most cases, fixture replacement parts don’t require a major investment.
  • Most common leaks can be eliminated after retrofitting a household with new WaterSense labeled fixtures and other high-efficiency appliances.

  • fix-a-leak-week-2017A good method to check for leaks is to examine your winter water usage. It’s likely that a family of four has a serious leak problem if its winter water use exceeds 12,000 gallons per month.
  • Check your water meter before and after a two-hour period when no water is being used. If the meter does not read exactly the same, you probably have a leak.
  • One way to find out if you have a toilet leak is to place a drop of food coloring in the toilet tank. If the color shows up in the bowl within 10 minutes without flushing, you have a leak. Make sure to flush immediately after this experiment to avoid staining the tank.

Faucets and Showerheads:

  • leaking-faucetA leaky faucet that drips at the rate of one drip per second can waste more than 3,000 gallons per year. That’s the amount of water needed to take more than 180 showers!
  • Leaky faucets can be fixed by checking faucet washers and gaskets for wear and replacing them if necessary. If you are replacing a faucet, look for the WaterSense label.
  • A showerhead leaking at ten drips per minute wastes more than 500 gallons per year. That’s the amount of water it takes to wash 60 loads of dishes in your dishwasher.
  • Most leaky showerheads can be fixed by ensuring a tight connection using pipe tape and a wrench. If you are replacing a showerhead, look for one that has earned the WaterSense label.

Toilets:

  • If your toilet is leaking, the cause is often an old, faulty toilet flapper. Over time, this inexpensive rubber part decays, or minerals build up on it. It’s usually best to replace the whole rubber flapper—a relatively easy, inexpensive do-it-yourself project that pays for itself in no time.
  • If you do need to replace the entire toilet, look for a WaterSense labeled model. If the average family replaces its older, inefficient toilets with new WaterSense labeled ones, it could save 13,000 gallons per year. Retrofitting the house could save the family nearly $2,400 in water and wastewater bills over the lifetime of the toilets.

Outdoors:

  • leaking-hoseAn irrigation system should be checked each spring before use to make sure it was not damaged by frost or freezing.
  • An irrigation system that has a leak 1/32nd of an inch in diameter (about the thickness of a dime) can waste about 6,300 gallons of water per month.
  • To ensure that your in-ground irrigation system is not leaking water, consult with a WaterSense irrigation partner who has passed a certification program focused on water efficiency; look for a WaterSense irrigation partner.
  • Check your garden hose for leaks at its connection to the spigot. If it leaks while you run your hose, replace the nylon or rubber hose washer and ensure a tight connection to the spigot using pipe tape and a wrench.

About 20% of our nation’s drinking water is “lost” before it reaches the consumer, amounting to about seven billion gallons of clean, treated water lost in this way every day. Also called non-revenue water, this lost water would be enough to supply the ten largest cities in the United States for a full year. It also accounts for billions of dollars in lost revenue each year – funds that utilities desperately need to keep their systems running smoothly and safely. Most of this non-revenue water is the result of our nation’s leaking, aging pipes, which received a grade of D on the American Society for Civil Engineers (ASCE) 2017 Report Card.

Fixing our Nation’s Infrastructure:

  • Conduct water audits, which take into account both real and apparent losses and are the most efficient, cost-effective way to accurately assess non-revenue water.
  • Conduct Capital Efficiency Plans™, which pinpoint and prioritize areas in a system most in need of improvement.
  • Pass legislation that increases available funding for water systems.
  • Conduct Business Practice Evaluations to allow utilities to function more efficiently and to utilize their limited dollars more effectively.

During Fix a Leak Week, while we focus on leaks and repairs in our homes, let’s also give attention to our nation’s crumbling infrastructure. Through careful management and capital planning, efficient use of infrastructure budgets, and increased infrastructure funding, we can assure we have a sufficient, safe, sustainable water supply for generations to come.

PPCPs and EDCs in Drinking Water – Is There a Solution?

PPCPs-drinking-waterModern-day, developed nations use an exorbitant amount of chemicals for a variety of reasons. Some of these chemicals are used to prevent and treat illness, to reduce pain from injury or surgery, to treat mental health issues, and for hygiene, grooming, and cosmetic reasons. Commonly referred to as Pharmaceutical and Personal Care Products, or PPCPs, these products include prescription and over-the-counter medications, cosmetics, fragrances, face and body washes, sunscreens, insect repellants, and lotions.

In addition to PPCPs are endocrine disrupting compounds (EDCs). The endocrine system is an intricate network of glands including the thyroid, pituitary, adrenal, pancreas, thymus, and reproductive organs that release precise amounts of hormones into the bloodstream in order to regulate essential biological functions in humans and animals such as growth, development, reproduction, and metabolism. EDCs are any external natural or synthetic compounds capable of interfering with the body’s endocrine system by disrupting the synthesis, secretion, transport, bonding, or elimination of natural bodily hormones.

Effects of PPCPs and EDCs in Water

prescription-drugs-waterPPCPs and EDCs enter our waterways through sewage, leachate from landfills and septic systems, flushing of unused medications, and agricultural runoff, and they have the potential to cause a myriad of problems. While there has not yet been a truly significant amount of research completed on all of these products and chemicals, some facts are known. For example, excessive antibiotic use has led to the development of “superbugs,” or bacteria such as MRSA that are resistant to most antibiotics. Methadone reacts with chloramine, a chemical used to treat drinking water, to form N-nitrosodimethylamine (NDMA), a known carcinogen. EDCs interfere with the endocrine system, potentially causing reproductive, developmental, neurological, and immunologic problems in both humans and wildlife.

US-drug-useSome of the most common EDCs in drinking water include estrogen and progesterone from birth control pills, as well as anabolic steroids. These compounds interfere with the reproductive capabilities of aquatic wildlife. Examples include eggshell thinning and subsequent reproductive failure of waterfowl; reduced populations of Baltic seals due to lower fertility and increased miscarriage; development of male reproductive organs in female marine animals, such as snails; feminization and subsequent decreased populations of certain types of fish, including bass; and reduced or malformed frog populations.

Regulating PPCPs and EDCs in Drinking Water

feminization-fishCurrently, most PPCPs and EDCs are not regulated at either the state or federal level; however, they are being investigated by the Environmental Protection Agency (EPA) as Contaminants of Emerging Concern. Because PPCPs and EDCs appear to hinder reproduction in marine life, many state environmental organizations strongly support additional research and potential regulation on these compounds. In 2006, Massachusetts became the first state in the nation to set drinking water and cleanup standards for the known EDC perchlorate after it had been detected in the state’s drinking water, and many states have implemented public education campaigns on these compounds, their effects, and their proper disposal.

Treating PPCPs and EDCs in Drinking Water

Currently, there are no treatment processes specifically designed to remove PPCPs or EDCs from drinking water; however, research is currently underway at the national level to determine the effectiveness of existing drinking water treatment technologies, such as chlorination, carbon filtration, and ozonation, on the removal of PPCPs and EDCs. In addition, several new, innovative technologies that specifically target PPCPs and EDCs for removal have shown promise. One example utilizes a catalyst called TAML(r), which is iron plus tetra-amido macrocyclic ligand, to remove PPCPs and EDCs from wastewater, while another utilizes zeolite adsorption to remove PPCPs and EDCs from water.

How We All Can Help Reduce PPCPs and EDCs in the Environment

drug-take-back-stateOn an individual level, taking small, simple steps can have a large impact on the amount of PPCPs and EDCs in our water supply:

  • Ask your health care provider to prescribe no more than the sufficient, effective quantity of medication, or consider a trial prescription before filling the full 30- to 90-day supply;
  • Buy OTC medications in small enough quantities that can be used before the expiration date;
  • Return all unused medications to pharmaceutical take-back programs that allow the public to bring unused drugs to a central location for proper disposal;
  • If a community take-back location is unavailable, remove unused or expired prescription medications from their original containers and throw them in the trash – never flush! To discourage abuse of certain types of dangerous medications such as narcotics, crush the pills and mix them with old bacon grease or other food waste.

In Conclusion

The problem of PPCPs and EDCs in drinking water does not appear to be going away any time soon. In order to mitigate damage caused to both humanity and the environment, additional research and focus must be placed on these compounds. It is imperative that we implement additional regulations, engineer innovative and cost-effective treatment technologies, increase funding to upgrade infrastructure, and reduce our personal contributions of PPCPs and EDCs to the environment.

National Groundwater Awareness Week 2017

National Groundwater Awareness Week is an annual occurrence sponsored by the National Ground Water Association (NGWA). During National Groundwater Awareness Week, NGWA aims to educate the public on the importance of groundwater and of preserving this precious resource. Many companies in the water industry, including Tata & Howard, support NGWA to help spread the word about groundwater.

All About Groundwater

groundwater-awareness-week Life as we know it would be impossible without groundwater, or the water that fills cracks, voids, and other openings in soil, sand, and bedrock. About 99% of the available freshwater on Earth is groundwater. Because of this, it is the world’s most extracted natural resource, at the rate of about 259 trillion gallons per year, with about 60% of that withdrawal going towards agriculture. Groundwater also supports our world’s ecosystems. People with wells use groundwater for drinking water, and most groundwater flows directly into streams, rivers, and lakes from beneath.

Do Your Part!

  • groundwater-awarenessIf you own a private water well, have your water tested annually or if there is a change in the odor, taste, or smell.
  • Don’t overapply pesticides, herbicides, and fertilizers. Use them only in the lowest recommended amounts. Better yet, try organic gardening and lawn care.
  • Don’t dispose of any hazardous substances by dumping them on the ground, pouring them down the drain, or flushing them down the toilet.
  • Contact local waste authorities about proper disposal of hazardous substances such as pesticides, herbicides, paint and paint thinner, antifreeze, fertilizer, oil, PPCPs and EDCs, or other chemicals.
  • Only handle hazardous substances over cement or pavement to avoid groundwater infiltration or runoff into surface water from accidental spills.
  • If you own a septic tank, have it inspected and serviced regularly to ensure that it is functioning properly and to prevent a breakdown that could pollute groundwater.
  • Decommission abandoned wells on your property using a qualified water well contractor.
  • Fix or replace any leaking aboveground or underground tanks (USTs) storing hazardous substances.
  • Don’t wash your car at home where the contaminated water runs back into the ground; rather take it to a certified car wash where proper wastewater management is required.

In Conclusion

groundwater-awarenessGroundwater is essential to human life and a healthy environment. Not only is it imperative that we protect groundwater from contamination by chemicals and waste, but it is also important to remember to conserve water wherever we can. Groundwater sources are being withdrawn at a faster rate than they are being replenished, and we cannot continue to utilize our world’s most precious resource with such abandon. Help NGWA spread the word during National Groundwater Awareness Week to ensure we all remember to do our part.
