Infrastructure Week 2019

From May 13-20, the seventh annual Infrastructure Week is taking place with the support of hundreds of affiliates across the country. Infrastructure Week was created to help raise awareness for our country’s growing infrastructure needs and stress the message that we must #BuildForTomorrow. Led by a coalition of businesses, labor organizations and policy organizations, this week will unite the public and private sector to send this important message to leaders in Washington and beyond.

No matter where you live, your age, your education, if you drive a car or a truck or take the bus or a bicycle, infrastructure has a profound impact on your daily life. We all have to get around. We all need lights to come on and water to come out of the tap.

Consequently, too much of our nation’s infrastructure is under-maintained, too old, and over capacity. When it comes to water infrastructure alone, we are dealing with a massive network of pipes that are well over 100 years old. In short, droughts in western states have caused wells and reservoirs to fall dangerously low; saltwater intrusion of Florida’s drinking water infrastructure, and dam and levee failures in California, South Carolina, and Louisiana have caused evacuations and put hundreds of thousands of people and homes at risk.

The High Cost of Water Infrastructure

And this is just the tip of the iceberg. A study conducted by the American Water Works Association revealed that the cost to replace our nation’s water infrastructures would cost more than one trillion dollars over the next 25 years.

No state, city, or county alone can tackle the growing backlog of projects of regional and national importance, and Americans get it: more than 79 percent of voters think it is extremely important for Congress and the White House to work together to invest in infrastructure.

For years, near-unanimous, bipartisan support for infrastructure investment has been steadily increasing. Leaders and voters have been rolling up their sleeves to spark efforts in the rebuilding and modernizing of transportation, water, and energy systems. Certainly, large strides have been made as a country, but there is still a lot to be done.

Every four years, the American Society of Civil Engineers (ASCE) publishes The Report Card for America’s Infrastructure, which grades the current state of the nation’s infrastructure on a scale between A and F. The last survey from 2017 gave tremendous insight into the state of our infrastructure surrounding drinking water, dams, and wastewater.

Drinking Water Infrastructure

The drinking water that we get in our homes and businesses all comes from about one million miles of pipes across the country. While the majority of those pipes were laid in the early to mid-20th century, many are showing signs of deterioration. There are many reasons for a water main to break including localized influences such as aggressive soil and weather conditions, as well as poor design/construction. Approximately 240,000 occur each year, consequently resulting in the waste of two trillion gallons of treated drinking water. Drinking Water received a grade of D.

Dams

The average age of the 90,000+ dams in the United States is 56.  Nearly 16,000 (~17%) have been classified as high-hazard potential. Dam failures not only risk public safety, they also can cost our economy millions of dollars in damages as well as the impairment of many other infrastructure systems, such as roads, bridges, and water systems. As a result, emergency action plans (EAPs) for use in the event of a dam failure or other uncontrolled release of water are vital. As of 2015, 77% of dams have EAPs – up from 66% in the last 2013 Report Card. Dams received a grade of D.

Wastewater

There are approximately 15,000 wastewater treatment plants across the U.S that are critical for protecting public health and the environment. In the next 15 years, it is expected that there will be 56 million new users connected to the centralized treatment system. This need comes with an estimated $271 billion cost. Maintaining our nation’s wastewater infrastructure is imperative for the health and well being of the 76% of the country that rely on these plants for sanitary water. Wastewater received a grade of D+.

In the water sector alone, it’s clear how heavily we rely on solid infrastructure. If the issues in our nation’s water infrastructure are not addressed, millions of people as well as our environment will be at risk. Many communities around the country are working hard to deliver projects to solve these problems – but there is always more to be done. Reversing the trajectory after decades of under-investment requires transformative action from Congress, states, infrastructure owners, and the American people. Join us this week to help spotlight the continued advocacy and education of infrastructure needs. Afterall, this is the true foundation that connects our country’s communities, businesses, and people.

 

Michael F. Knox Joins T&H as Client Service Specialist

Water and Wastewater Professional Mike Knox to Run Emergency Response Training Programs

Tata & Howard, Inc., a leading innovator in water, wastewater, and stormwater engineering solutions, is pleased to announce that Michael F. Knox, has joined the firm as a Client Service Specialist. In this newly created role, Mr. Knox will concentrate on developing Emergency Response Training Programs to be offered starting this fall.

Prior to joining Tata & Howard, Mr. Knox worked as the Superintendent and Chief Operator for the Cherry Valley and Rochdale Water & Sewer District in Leicester, Massachusetts. He holds a 2C and 3T drinking water license and a 3M wastewater license, and he has a B.S. in Mechanical Engineering.

In addition, Mr. Knox served as a member of the Massachusetts Water and Wastewater Agency Responses Network (MAWARN) Steering Committee and was the MAWARN Chair from 2008 to 2011.  He is a member and Past President of the Massachusetts Water Works Association (MWWA).

“As a former Superintendent and Chief Operator of a Water & Sewer District, Mike brings a unique perspective to this position,” Paul B. Howard, P.E., T&H Senior Vice President stated. “Having worked with Mike in the past, we knew of his experience and expertise improving the safety and security of municipal assets and implementing emergency response programs.”

“We’re excited to have Mike on our team,” Karen L. Gracey, P.E., T&H Co-President said. “Mike’s knowledge and thorough understanding of critical emergency response methodologies and training skills will not only benefit municipal water operations but also help improve their service to the community water systems they manage.”

Emergency Response Plans (ERPs) are mandatory for all public water suppliers, and a minimum of 10 hours of Emergency Response Training is required.  ERP training is a process that helps water system managers and staff explore vulnerabilities, make improvements, and establish procedures to follow during an emergency. Preparing and practicing an ERP can save lives, prevent illness, enhance system security, minimize property damage, and lessen liability.

3 Sustainable Clean Water Ideas for a Warming World

Climate Change Brings New Innovation to the Water Environment

The summer of 2018 saw devastating fires blazing all over the world. Nearly 100 people died in raging fires across the southern coast of Greece. More than 50 wildfires scorched Sweden where the temperature north of the Arctic Circle soared into the 90’s causing drought conditions. Record breaking temperatures across the globe from Montreal to Great Britain topped 98 degrees this summer.  In Japan, 22,000 people were hospitalized when temps climbed to 106 degrees. And, in normally cool Oslo, the thermometer climbed to 86 degrees for 16 consecutive days. From Southern California and Arizona to India and Pakistan, withering heat reached a deadly 110 degrees that parched the environment.

ThermometerThe most alarming news is the hottest temperature ever reliably recorded reached 124.3 degrees in Algeria this July.

Fires, heat and drought of this scope and scale seem to be becoming the new normal. These extreme events point to a planet that is warming and perhaps faster than scientists have predicted.

Although the effects of climate change may vary widely in different geographic regions, those areas already hardest hit with drought and arid conditions may be in the most critical need of clean drinking water.

This crisis will only get worse as the earth’s population conceivably could grow exponentially in the next 50 years and adequate supplies of water become even more scarce. In addition to supplying all these thirsty people with clean water, the chilling paradox is the increased demand on already-scarce resources means there is a greater chance that existing water sources will become polluted by human waste, industrial toxins, and contaminated agricultural runoff.

It is human nature to postpone change and sacrifice as long as possible. But it is clear that public service announcements warning residents to save water, take shorter showers, plant resilient gardens, and conserve, is not going to be enough to help avoid a global water shortage.  Fortunately, scientists and researchers are working diligently to solve some very complex problems to provide innovative and sustainable clean water solutions for the future.

Here are three cutting edge ideas for sustainable water supplies that just may help a warming world.

Ancient Bacteria for Modern Water Purification

Anaerobic or oxygen-averse bacteria to treat wastewater is back in vogue… after a billion years. When the earth was a toxic primordial goo, anaerobic bacteria thrived in the oxygen deprived world forming the first signs of life.  Environmental engineers at Stamford University are now bringing back these ancient microorganisms as a more cost-effective wastewater treatment process.

Primordial-bacteriaWastewater treatment plants that use aerobic bacteria must provide oxygen with huge and costly electrically powered blowers for these microorganisms to survive. Anaerobic bacteria treatment processes do not need oxygen and use considerably less energy, making the wastewater treatment process more economical to operate. In addition to saving money, engineers believe these anaerobes can filter household and industrial chemicals better than conventional treatment plants.

Full-scale plants utilizing anaerobic bacteria may soon be capable of processing millions of gallons of wastewater per day into refreshing clean water.

Mega Scale Desalination

Desalination plants may not have been around as long as ancient bacteria, but this technology is not a new concept either.  What is news however, is the increasing role desalination will have in the future. Israel’s Sorek desalination plant is the largest seawater reverse osmosis (SWRO) desalination plant in the world providing 627,000 cubic meters per day (m3/d) or the equivalent to about 166,000,000 gallons of water per day (gpd) to Israelis.

desalination-plant

Desalination plants which were notoriously expensive energy hogs have become less energy-intensive as technologies have improved. Using renewable energy, such as solar, wind and geothermal along with advanced technologies including thin-film nanocomposite membranes, captive deionization (most suitable for brackish water), forward osmosis, and metal–organic framework (MOF) biological cell membranes that requires very little water pressure, water desalination is becoming more efficient and cost effective. The new cutting-edge membranes can even filter out precious metals such as lithium used in batteries.

Saudi Arabia, the largest producer of desalinated water in the world with its 32 desalination plants and growing, will soon be producing a historic 5 million m3/d or the equivalent of about 1,321,000,000 gpd, a global record of desalinated water. Benefiting from this leading-edge technology, Cape Town South Africa may have averted a catastrophic “Day Zero” when the City’s first desalination plant went online, preventing a water doomsday for its residents.With the world’s oceans holding about 96.5 percent of all Earth’s water and with more innovation, desalination may prove to be this thirsty world’s salvation.

 

Drinking Water from the Air

Another old idea that is gaining favor is converting fog into drinking water. Super-sized moisture collection systems could allow people living in coastal or mountainous areas to convert fog into safe drinking water. Collection traps are made from a 3D mesh that can withstand high wind speeds, while still retaining and accumulating water in storage tanks. With a variety of sizes available, these fog systems can be used for individual needs or supplying water for entire villages.

fog-nets
Super-sized fog nets can capture moisture in coastal or mountainous areas to convert fog into safe drinking water.

Combine this idea with giant Atmosphere Water Generators (AWG), which takes moisture or humidity directly out of the air and converts it into potable water.  Even in the driest of lands, the air is loaded with water molecules and enough drinking water converted from AWG’s could provide communities with a continuous and sustainable source of clean water.

On a large scale, the AWG units can be mounted on the roof-tops of commercial or residential buildings.  When powered by renewable energy, these systems can create safe local drinking water efficiently and economically. Water districts and municipalities managing these units, can provide as much as 55 m3 /d or about 14,500 gallons per day, enough to service each building independently with water.

AWG Towers
Large scale Atmosphere Water Generators can be installed on roof tops.

Collected water from both fog collection systems or AWG’s may seem farfetched. But consider this, 80 percent of California’s water goes to irrigate farms and the other 20 percent of water use goes to urban use. Collected water from the air could be used to irrigate crops or other commercial watering needs.

Water conservation and alternative technologies such as fog collection systems and AWG units can supplement our increasing demand for clean water and these ideas just might may make a difference.

 

The Future is for Innovation

Combating climate change and managing our depleting water resources is a reality we can’t ignore. The devasting fires, drought and heat from 2018, is a reminder that our actions today may help avert a global catastrophe in the future. These innovative ideas and others still in development are one step forward to a more sustainable world.

Our future depends on it!

Drinking Water That is Out of This World

Reclaiming Wastewater on the Space Station has an impact right here on Earth!

Water—it’s essential for all living beings… and water is essential to make life possible.   It’s an interesting paradox that has kept scientists searching for life in extreme places.

Outer spaceWhen NASA recently announced the discovery of liquid water flowing under an ice cap on Mars, it opened the exciting possibility that life may exist outside our earthly abode.  While it is conceivable scientists may eventually discover life somewhere in our galaxy, a reliable source of water outside earth is fundamental for the possibility of establishing a colony on Mars, exploring the universe and even visiting distant planets in search of life outside earth.

This is the stuff of science fiction…or is it?

Well, let’s get the stars out of our eyes and return to earth.  First, we need to get to Mars and therein lies the challenge. Top on the list is how to provide the essentials for life, such as water, air and the entire habitat for the astronauts to live in as they journey among the stars.

Getting to Space

Establishing a sustainable long-term flight program requires a base to launch manned operations in space. The International Space Station (ISS), which was put into orbit in 1998 and has been continuously occupied since 2000, currently provides a habitable place for astronauts to live and conduct scientific experiments.

SpaceX Docking in ISSBut hauling tons of supplies and materials to the International Space Station (ISS) is inefficient and extremely expensive. Sustaining a crew of four astronauts on the ISS with water, power and other supplies, costs nearly one million dollars a day.  Even with the reusable SpaceX rocket which regularly provides supplies to the ISS, it costs $2,500 per pound to launch into space. With four astronauts living on the ISS needing approximately 12 gallons of water a day, it is impractical to stock the ISS with the tons of water needed for long periods of time.

It’s no wonder then that rationing, and recycling is an essential part of daily life on the ISS.  The Space Station must provide not only clean water, but air to breath, power, and ideal atmospheric conditions to sustain life outside earth.

And every drop of liquid is important!

Reclaiming Water for Life Support

The Environmental Control and Life Support System (ECLSS) on the ISS is a life support system that provides atmospheric pressure, oxygen levels, waste management and water supply, and fire detection and suppression. The most important function for ECLSS is controlling the atmosphere for the crew, but the system also collects, processes, and stores waste and water produced by the crew…including the furry lab passengers too.

Yes, even mice waste is recycled.

mouse and waterIf the idea of drinking reclaimed water from mice urine and other waste sources sounds unappetizing, consider this, the water the astronauts drink is often cleaner that what many earthlings drink.  NASA regularly checks the water quality and it is monitored for bacteria, pollutants and proper pH (60 – 8.5).

This highly efficient reclamation system processes and recycles fluid from the sink, shower, toilet, sweat, and even condensation from the air. The ECLSS water recovery system on the ISS uses both physical and chemical processes to remove contaminants, as well as filtration and temperature sterilization to ensure the water is safe to drink.

More Innovation for the Future

Providing the astronauts with clean water from reclaimed wastewater at the Space Station is working fine for what they need right now, but it’s not perfect. The ISS system recovers water at a rate of approximately 74 percent. For longer missions to Mars and beyond, this rate must increase to at least 98 percent to sustain longer journeys into space. Scientists are continuously working on better and more efficient close-looped support systems to reduce water loss and improve ways to reclaim water from all waste products.

bacteriaRecently, NASA invested in a new, lower cost solution to biologically recycle and reuse water developed by Pancopia. Pancopia is a small environmental and energy engineering company located in Virginia that focuses on wastewater treatment and research and development projects. Engineers at the firm have discovered an innovative technology that makes use of a group of bacteria called anammox.  Anammox when combined with two other types of bacteria commonly used in conventional wastewater treatment (nitrifiers and denitrifiers), can remove high levels of organic carbon and nitrogen, the two primary pollutants in wastewater.

The combination of these three organisms naturally adjust to changes in the system and eliminates pollutants faster and more reliably than traditional wastewater treatment operations.  And, the cost is significantly less to operate than conventional systems, which requires a lot of energy and consumables to run. In addition, the stability of the anammox process reduces costs by requiring fewer manpower hours to monitor and operate.

Back on Earth

What does all this water and wastewater reclamation innovation mean for us on earth?

Desert in WaterPancopia is currently working on a similar system used on the ISS for municipal wastewater facilities. Using the technology developed for the Space Station, other areas in the world with limited access to clean drinking water, will soon be able to utilize this advanced water filtration and purification system.

This innovative water recycling system initially intended for the astronauts, now has the potential to cut treatment expenses to less than half the current costs for municipal customers, while providing sustainable crystal-clear drinking water especially in arid and drought-stricken communities across the globe.

Man’s search for extraterrestrial life and desire to travel through space may actually have its greatest impact right here on Earth—clean water!

State Revolving Fund Loan Program

The Massachusetts Department of Environmental Protection (MassDEP), is now accepting Project Evaluation Forms (PEFs) for new drinking water and wastewater projects seeking financial assistance in 2019 through the State Revolving Fund (SRF).  The SRF offers low interest loan options to Massachusetts cities and towns to help fund their drinking water and clean water projects. PEFs are due to the MassDEP Division of Municipal Services by August 24, 2018, 12:00 PM.

Water Main ReplacementFinancing for The Clean Water SRF Program helps municipalities with federal and state compliance water-quality requirements, focusing on stormwater and watershed management priorities, and green infrastructure. The Drinking Water SRF Program, provides low-interest loans to communities to improve their drinking water safety and water supply infrastructure.

This year, the MassDEP Division of Municipal Services (DMS) announced the following priorities for SRF proposals.

  • Water main rehabilitation projects which include full lead service replacement (to the meter) – this is a high priority for eligibly enhanced subsidy under the Drinking Water SRF.
  • Reducing Per- and polyfluoroalkyl (PFAS) contaminants in drinking water.
  • Asset Management Planning to subsidize Clean Water programs.
  • Stormwater Management Planning for MS4 permit compliance and implementation.

PFAS – Emerging Contaminants in Drinking Water

Health Advisory Guidelines for Per- and polyfluoroalkyl Substances Detected in Public Water Systems

The Massachusetts Department of Environmental Protection (MassDEP) announced in early June, and through the Office of Research and Standards (ORS), its recommendations on the Unregulated Contaminant Monitoring Rule 3 (UCMR 3) for emerging contaminants-specifically Perflourinated Alkyl Substances (PFAS).

PFAS or Per- and polyfluoroalkyl substances are a group of man-made compounds that include perfluorooctane sulfonate (PFOS), perfluorooctanoic acid (PFOA), perffluorohexane sulfonate (PFHxS), perfluorononanoic acid (PFNA), perflouroheptanoic acid (PFHpA), and perfluorobutane sulfonate (PFBS).

US map of PFASAccording the Environmental Protection Agency (EPA), all these UCMR 3 PFAS compounds have been detected in public water supplies across the US. Since PFAS are considered emerging contaminants, there are currently no established regulatory limits for levels in drinking water. However, in 2016, the EPA set Health Advisory levels (HA) of 0.07 micrograms per liter (µg/L) or 70 parts per trillion (ppt) for the combined concentrations of two PFAS compounds, PFOS and PFOA.

MassDEP’s ORS established drinking water guidelines that follows the EPA’s recommendations for health advisory levels at 70 ppt, which applies to the sum total of five PFAS chemicals – PFOS, PFOA, PFNA, PFHXS, and PFHpA.  And, if the level of contamination poses unacceptable health risks to its customers, Public Water Systems (PWS) must take action to achieve safe levels. They also must provide public notice.

The EPA and MassDEP’s recommended guidelines for PFAS include:

  • Public Water Suppliers take immediate action to reduce levels of the five PFAS to be below 70 ppt for all consumers.
  • Susceptible health-risk groups (pregnant women, infants, and nursing mothers) should stop consuming water when the level is above 70 ppt.
  • Public Water Systems must provide a public Health Advisory notice.

Water testingThe EPA also recommends that treatment be implemented for all five PFAS when one or more of these compounds are present.

Although, PFAS are no longer manufactured in the United States, PFAS are still produced internationally and can be imported in to the country1.  PFAS have been in use since the 1940’s and are persistent chemicals that don’t breakdown, accumulate over time in the environment and in the human body.  Evidence shows that prolonged exposure PFAS can have adverse effects on human health and the ecology.

PFAS can be found in:

  • Agricultural products grown in PFAS-contaminated soil or water, and/or handled with PFAS-containing equipment and materials.
  • Drinking water contaminated from chemical groundwater pollution from stormwater runoff near landfills, wastewater treatment plants, and firefighter training facilities2.
  • Household products, including nonstick products (e.g., Teflon), polishes, waxes, paints, cleaning products, and stain and water-repellent fabrics.
  • Firefighting foams2, which is a major source of groundwater contamination at airports and military bases where firefighting training occurs.
  • Industrial facilities that manufactured chrome plating, electronics, and oil recovery that use PFAS.
  • Environmental contamination where PFAS have built-up and persisted over time – including in fish, animals and humans.

While most states are relying on the EPA’s Health Advisory levels (including Massachusetts), some, such as Connecticut, Minnesota, New Jersey, Arizona, and Colorado have addressed other UCMR 3 PFAS pollutants as well.

Boy drinking waterMost research on the effects of PFAS on human health is based on animal studies. And, although there is no conclusive evidence that PFAS cause cancer, animal studies have shown there are possible links. However, PFAS ill-health effects are associated with changes in thyroid, kidney and liver function, as well as affects to the immune system.  These chemicals have also caused fetal development effects during pregnancy and low birth weights.

PFAS are found at low levels throughout our environment—in foods we consume and in household products we use daily. PFAS in drinking water at levels higher than the EPA’s recommendations does not necessarily mean health risks are likely. Routine showering and bathing are not considered significant sources of exposure. And, while it is nearly impossible to eliminate all exposure to these chemicals, the risk for adverse health effects would likely be of concern if an individual continuously consumed higher levels of PFAS than the guidelines established by the EPA’s Health Advisory.

MassDEP is continuing its research and testing for PFAS in Public Water Systems.  Large Public Drinking Water Systems have already been tested and sampling indicated that approximately 3% had levels of PFAS detected. MassDEP is currently working with smaller Public Water Systems to identify areas where PFAS may have been used or discharged to the environment.

As more information and regulations develop on this emerging contaminant, MassDEP will continue to communicate their findings. Tata & Howard is also available for any questions that may arise, as well as, assist with testing and recommend treatment options for our clients.

 

1 In 2006, the EPA and the PFA industry formed the PFOA Stewardship program to end the production of PFAs.

2 MassDEP in partnership with the Massachusetts Department of Fire Services (MassDFS), announced in May a take-back program to remove hazardous pre-2003 firefighting foam stockpiles and be neutralized. Manufacturers stopped making PFAS foam in 2002 and have since developed fluorine-free and more fluorine stable foams that are safer to the environment.

Please Do Not Flush

Please Do Not Flush

Even though a product may be small enough to flush, does not mean it should be. Flushing items down the toilet that are not meant to be flushed, including those labeled flushable, can lead to problems in the sewer system, at the wastewater treatment facility and for the environment.

This handy two-page infographic illustrates things never to flush!

Please Do Not Flush

An Indispensable Guide to Flushing

Here’s a problem that nobody wants to mess with, clogged toilets, backed up sewer systems, and the costly repairs to fix this stink.

ToiletWhile there are many obvious things not to flush down the toilet, an astonishing amount of non-flushable wipes, paper products, dental floss, and other dispensable hygiene products are flushed down toilets every day. This has contributed to cities and municipalities dealing with chronic clogged sewer systems and expensive wastewater treatment maintenance, not to mention homeowners who face the inconvenient problem of having a toilet back up in their home.

These raw sewage messes aren’t pretty and are not easy or inexpensive to fix.

Here’s the indispensable truth about what goes down the toilet.

manholeEven though many items can be flushed down the toilet, it’s misleading to believe that everything is ‘flushable’ and safe for our sewer systems and environment. The journey is just beginning when that swirling eddy of water makes everything in the toilet bowl disappear.

All the solids flushed down the toilet that don’t dissolve, eventually end up at a wastewater treatment facility. Traveling miles and miles through pipes underneath our streets and sidewalks, this raw sewage flows by gravity or with the help of pump stations towards a wastewater treatment facility. Most of this waste is taken care of, out of sight, by Municipalities who work every day to maintain this process.

However, the pump stations are periodically clogged by non-disposable waste that is flushed down the toilet. Products that are designated as ‘non-flushable’ are often made with plastic fibers and do not break down in wastewater systems. Even products that are labeled as ‘flushable’, do not easily disintegrate in water like toilet paper.

Wastewater Plant

For example, popular flushable personal care wipes (for both babies and adults) are marketed as a convenient, portable, and a hygienic way to keep clean. Manufacturers claim these flushable wipes are septic-safe or safe for sewer systems. The problem is these products take much longer to break down as compared to traditional toilet paper.

And, here’s the reason why.

A well-known manufacturer of flushable wipes claims their product passes what is called a ‘slosh’ distribution test. The wipes, which are made of ‘non-woven clothlike material’, must be strong enough to handle the manufacturing process, hold up while being used, and still be weak enough to break apart after being flushed down the toilet.

slosh test boxThe slosh test checks the potential for wipes to break down in water during agitating conditions. A box containing water and one or more wipes tips back and forth, slowly and repeatedly “sloshing” the wipes for three hours. All fibers from the test are strained from the slosh box and then poured through a 12½-millimeter sieve (consistent with industry guidelines) and rinsed for two minutes to measure the percentage of fiber material that passes through the sieve.

The problem is, unlike toilet paper that quickly disperses in circulating water, the tightly woven fabric of the wipes takes much longer to breakdown (as noted in the slosh test), and while these products may not clog pipes immediately, imagine everything flushed down the toilet snagging on it, expanding, and gathering together to clog pipes and sewage pumps.

Sewer workersPrivate and municipal sewer system operators end up sifting through what’s left in the wastewater to clear these obstructions—often costing millions of dollars to maintain and repair.

Sadly, many of these disposable products are regularly flushed down the toilet. In a recent study, more than 98 percent of what was found at a wastewater treatment plant was non-flushable personal care wipes, paper towels, dental floss, diapers, tampons, condoms, cleaning wipes and other ‘trash’ not intended to be flushed.

And there are many more flushing no-nos—seemingly harmless and not so harmless items regularly flushed down the toilet.

Here is a list of things never to flush:

Baby wipes and diapers (including types labeled ‘flushable’ or ‘disposable’): Diapers can take up to 500 years to degrade in a landfill. These highly absorbent synthetic materials are slow to breakdown and can block sewer systems.

Paper towels: Just like wipes, these common household items are designed to not breakdown when wet and absorb liquids.

Cotton balls, cosmetic pads and cotton swabs: These items tend to gather in pipe bends causing blockages.

Dental Floss:  This little string can cause havoc to plumbing and sewer systems.

Medications or Supplements: Wastewater treatment facilities are not designed to breakdown pharmaceuticals. While drugs may dilute in the waste stream, studies have shown the presence of medicines such as steroid hormones and antidepressants in wastewater effluent. The EPA1 refers to this as “Personal Care Products as Pollutants,” which also includes residues from cosmetics, agribusiness, and veterinary use.

Medical Supplies: Razors, bandages and hypodermic needles are often flushed, but quite simply, they don’t degrade. The razor blades and needles also present a danger to employees who need to remove the items that clog the system.

Rubber:  Items such as latex gloves and condoms, are made of a material that is not intended to breakdown in liquid.

Cat litter (including types labeled ‘flushable’): The absorbent properties of litter (generally clay and sand) are designed to ‘clump’ and will clog sewer systems.

Feminine Hygiene Products (sanitary napkins, tampons and applicators): Like cat litter, these products are designed to absorb liquids and swell in the process, clogging pipes, get stuck in bends and block sewer lines.

Fats, oil, and grease: Known in the wastewater industry as ‘FOG,’ are liquids that solidify when cooled, and this creates significant problems for public wastewater systems, as well as drains in your home.

Hair: Like dental floss, flushed hair can cause tangled blockages ensnaring everything that passes by.

Food products: banana peels, apple core, leftovers.  While these may degrade over time, food products simply do not disintegrate fast enough and can cause blockages throughout the system.

Trash of any kind: All this litter does not easily biodegrade.

  • Candy and other food wrappers
  • Cigarette butts
  • Rags
  • Plastic Bags

Chemicals: paint, automotive fluids, solvents, and poisons, are just terrible pollutants to flush. Just as wastewater treatment plants are not designed to screen out pharmaceuticals, these facilities are not designed to eliminate toxic chemicals.

Heavy Metals: These pollutants include, mercury, cadmium, arsenic, lithium (think batteries) and lead, etc. Please dispose of any of these toxins properly to prevent harm to the environment and the potential for serious health risks.

Flushable toilets and the wastewater facilities that treat our raw sewage are indispensable services in modern life.  It’s long time we take responsibility and think twice about what is flushed down the toilet—for the sake of our sewers systems and wastewater treatment processes, and our indispensable precious environment.

Tata & Howard to Conduct Water Asset Management Plan and Hydraulic Study

Turner Falls, MA benefits from $40,000 state grant to improve water system

Turner Fall MAMARLBOROUGH, MA, January 15, 2018Tata & Howard, Inc., a leading innovator in water, wastewater, stormwater, and environmental engineering solutions, was named the principal engineering firm to conduct a water asset management plan and hydraulic study for the water district in Turner Falls, MA.

Turner Falls will soon be able to assess their water inventory infrastructure after receiving a $40,000 grant from the Baker-Polito administration.  Turner Falls is one of ten communities in Massachusetts to receive a portion of $388,000 in grant monies from the state to improve the town’s drinking water systems or wastewater systems.

Tata and Howard, will assist the town in completing an asset management plan and hydraulic study, which will including above and below ground reviews.

Working with Mike Brown, superintendent for the water district, the study will include an inventory of water mains, age of pipes, past inspection reports, dates when wells were installed, and water quality tests.  “I was very excited to see we were qualified, said Mr. Brown.  “Some of our mains are 80-100 years old and could be corroded or built up with mineral deposits.”

According to Karen Gracey, co-president of Tata and Howard, “The grant is specifically for the funding of the plan and study. We are scheduled to begin in February and complete the report by May.”

From the information gathered and analyzed, Tata and Howard will make recommendations for water infrastructure improvements and replacements.
