The Importance of Water & Wastewater Infrastructure Investment

As stated so eloquently by The Value of Water campaign, “…virtually all sectors of the economy rely on water.” In their report completed in 2017, water, wastewater and stormwater engineers associated with the campaign enumerated the vast number of business sectors that rely on sound water and wastewater infrastructure to successfully conduct and maintain their work, “from semiconductor manufacturing, to agriculture, to hotels and restaurants.”

But what happens when these profoundly significant resources begin to age and become unreliable, or even dangerous? What happens when the United States, and the world at large, does not allocate the proper amount of funds to crumbling water and wastewater infrastructures?

We are now seeing the consequences of poorly funded infrastructure due to our current unprecedented circumstances brought on by COVID-19. The Guardian cited a study in early March from the UN World Water Development report that expressed serious concern over “underfunding of water infrastructure around the world.” Such underfunding prevents access to clean water, which has become the first line of defense against COVID-19 as the CDC advises everyone to wash frequently with soap and water. However, even before and beyond the COVID-19 pandemic, underfunded water infrastructure has led many communities to suffer challenges related to poor drinking water quality and the unaffordability of access to clean water.

In her address to the Committee on Transportation and Infrastructure within the U.S. House of Representatives, Angela Lee, director of Charlotte Water in North Carolina, explores the economic strain non-federally funded water infrastructure can have on low-income families. When the federal government does not support infrastructure projects, water and sewer rates soar, making it increasingly difficult for ratepayers with lower incomes to keep up. Lee states, “In many communities [in the U.S.] the lowest 20 percent of earners pay almost one-fifth of their income towards their water bill.” Drawing from her own observations in Charlotte, NC, Lee reveals, “Charlotte Water serves just over 285,000 accounts but provided 58,636 payment arrangements in 2018. Public Utilities may be forced to delay much needed projects to avoid overburdening customers.”

Luckily, in late April, members of the U.S. Senate Committee on Environmental and Public Works (EPW) John Barrasso and Tom Carper, released two bills, the America’s Water Infrastructure Act of 2020 (AWIA 2020) and the Drinking Water Infrastructure Act of 2020 (DWIA 2020). The AWIA 2020, helpfully summed up here,

includes approximately $17 billion in new federal authorizations for infrastructure investments across the United States, which are intended to increase water storage, provide protection from floodwaters, deepen nationally significant ports, maintain the navigability of inland waterways across the country and repair aging wastewater and irrigation systems.

The DWIA 2020 includes an estimated $2.5 billion and, according to a memo released by the senate committee, seeks “to provide resources and technical assistance to communities facing drinking water emergencies that present substantial danger to health.” The bill will also provide “robust funding for grant programs to help water utilities invest in and deploy new and emerging, but proven, technology essential to improve water and energy efficiency, reduce emissions, and expand ratepayer affordability.”

The grant programs the DWIA 2020 could potentially support within New York State include the NYSEFC’s Drinking Water State Revolving Fund, which funds municipally and privately owned public water systems that provide drinking water; the Water Infrastructure Improvement Act (WIIA), which provides water quality protection across New York; the USDA’s Water and Waste Disposal, Rural Development Grant Program, a program that supports clean and reliable drinking water systems in rural areas; and the Community Development Block Grant, which funds water and sewer main improvements. Other funding programs available in NYS are the Engineering Planning Grant, which seeks to advance water quality projects to construction, and the Clean Water State Revolving Fund, which finances wastewater and water quality improvement projects to municipalities throughout New York State. Follow the embedded links for more information on the benefits each grant provides, and how to apply. You can also follow this link for a comprehensive list of other grants offered in New York State.

What funding has already been included in NYS’s 2020 budget? The Executive Budget, as formally announced by New York State, includes $2.5 billion for clean water infrastructure, “beginning with a new $500 million appropriation to support drinking water infrastructure, wastewater infrastructure, and water quality protection” and $300 million for the Environmental Protection Fund (EPF), which includes funds allocated to water quality improvement.

p+d continuously strives to remain aware of all funding opportunities and assist the communities we serve through obtaining and administering grant funding. We have worked on a wide variety of grant-funded projects. For example, p+d assisted the Village of Cornwall-on-Hudson with obtaining $1 million in WIIA/IMG grant funding for improvements to the Taylor Road Well Field; these improvements were needed in order to increase resiliency and add additional capacity to the Village’s water supply. We similarly assisted the Town of Gardiner in obtaining an Engineering Planning Grant for an I/I study of their collection system. We’ve also administered Environmental Facilities Corporation (EFC) funding for the Village of Suffern’s Phase 2 Sewer Abatement, which addressed areas in the Village’s collection system that were found to have elevated levels of infiltration and inflow (I/I). Lastly, p+d has worked on a variety of projects associated with the Town of Wallkill’s EFC grant funding, which they received specifically for the development of several new projects within their wastewater collection system. p+d was tasked with managing these funds for the Town while designing the upgrades.

Water & Wastewater Engineers Help in the Fight Against COVID-19

It is heartening to see so many in our field seeking innovative ways to help our country battle the coronavirus. Here are a few key ways water and wastewater engineers have pitched in to keep everyone safe and healthy:

Global technology company Xylem is repurposing water pumps in to ventilators. Aquatech reports that the water company has been utilizing their Jabsco flow control pumps, typically used “in the recreational boats and vehicles and food and pharmaceutical markets,” to create ventilators that will be delivered to several hospitals once the design has been approved.

Wastewater engineers have also been assisting with the testing of water samples from sewer systems. These tests can detect the spread of COVID-19. Bay Area researchers have been tracking their local wastewater treatment plants by testing the samples for “traces of genetic material from SARS-CoV-2, the virus that causes Covid-19.” This testing of the sewer systems could supplement the need for nation-wide COVID-19 testing of individuals. Some evidence suggests that when a person first contracts the virus, they can shed some of their viral load into their fecal matter. At the University of Michigan, associate professor Krista Wigginton is leading a team of civil and environmental engineers in similar testing, and her team is seeking to answer the question “Can we slow the spread through sewer surveillance?”

Following NY’s shelter-in-place order, it might also become imperative for environmental, water, and wastewater engineers to test water quality in buildings that have been on shut down for prolonged periods of time, as stagnant water could pose health risks. According to phys.org, “water left sitting for long periods of time could contain excessive amounts of heavy metals and pathogens concentrated in pipes nationwide.” Associate professor of civil and environmental engineering Andrew Whelton is conducting a study to determine how safe the water in shut-down buildings will be after the pandemic. Once results of the study are available, researchers will “advise public health officials, building owners and water utilities on how to safely recommission buildings with low or no occupancy due to the pandemic.”

We are so proud to belong to a field that can offer such profoundly versatile and flexible skills, especially in times of severe need such as these. While times seem uncertain, it is helpful to know that we are all putting our heads together in pursuit of a healthier future.

Changing Seasons & Changing Engineering

With the changing seasons comes changes in our methods of engineering. What does it mean for p+d when the trees start to bloom, the ground becomes a bit softer, and the air becomes a bit warmer?

The construction projects that we manage and oversee are largely affected by these changing weather conditions. Specifically in the spring and summertime, the increase of rainfall and moisture in the air can force us as consultants to alter the materials we had originally planned on using in some of our projects. Materials such as “wood, hot melt adhesives and paints” are very susceptible to warming temperatures and moisture in the air as they tend to become less adhesive to particular surfaces. Heat can also cause certain materials to expand, “lead[ing] to misaligned joins during construction.” Winter inevitably brings issues as well—when contractors are met with a frozen ground, it becomes quite difficult for them to conduct key construction tasks such as excavation. Another issue unique to winter-weather conditions is the potential freezing of concrete, which can become “weak, brittle and even flaky” during the pouring process.

Changing weather conditions are so important for engineering and construction firms to consider that the National Center for Atmospheric Research, based in Boulder, CO, created “a prototype web tool, Climate-i Construction […] that applies seasonal outlook data to construction risks.” This invaluable tool tracks weather patterns months in advance to help engineers and construction workers to determine potential weather-related issues that might impact significant construction activities such as pouring concrete or operating a crane. This month specifically, our projects may be impacted by muddier conditions and increased temperatures that may alter our chosen materials.

For us in the water and wastewater industry, we must also contend with changing temperatures and the effects this climate shift might have on the water that exists within the plants where we complete our work. Increased temperatures inevitably alter water chemistry, sometimes causing “higher electrical conductivity” in groundwater, a source from which some water treatment plants receive their supply. High conductivity means that the water contains a large amount of “mineral salts of elements like sodium, calcium and magnesium” and is thus “related to high TDS (total dissolved solids).” For p+d, this means our water treatment designs must place a heavier focus on reducing TDS during the treatment process. While developing designs for septic systems, we also must take in to consideration the best weather conditions under which to perform perc tests, which “measures the rate at which water is absorbed (percolates through) the soil.” The drier the soil, the more easily it will absorb moisture, leading to much better results. During winter and spring when the ground is typically saturated with either snow or rainfall, the perc test is less likely to be effective.

Many wastewater treatment plants have seasonal disinfection limits, meaning the wastewater effluent is not required to be disinfected during late fall, winter and early spring due to reduced microbial action brought on by low temperatures. Operators are now getting their disinfection systems in order for disinfection in the late spring, summer and early fall. WWTP operators also look forward to warmer weather because of the increased microbial action in the wastewater, making it easier to comply with ammonia, TKN and denitrification requirements.

Changes in temperature bring special challenges to our industry that we are always eager to anticipate and address. This season in particular always keeps us on our toes and allows us to use our problem-solving skills to constantly adjust to these changing conditions. We hope you all have a wonderful spring!

p+d Awarded Copper & Zinc Investigative Study

p+d has been collaborating with the Village of Suffern to study the Village’s wastewater system to identify the users, industries or other sources whose processes or systems could potentially release metal contaminants. This study will involve a volumetric comparison and evaluation of users’ waste stream characteristics to determine each user’s potential contribution of metals.

Our team has studied the Village’s water and sewer records and examined case studies and peer-reviewed articles regarding copper and zinc leaching. Using our research and intimate knowledge of the Village’s water and sewer systems, we have identified strategic sampling locations and frequencies to most efficiently evaluate the water treatment facilities’ source contributions of copper and zinc. Once sampling is complete, we will analyze the findings and prepare a lab report summary and evaluation and recommendation report. 

p+d Selected for the Complete Rehabilitation of and Permit Transfer for the Pike County Environmental Enterprises Wastewater Treatment Plant

p+d has been selected to provide engineering and consulting services for the complete rehabilitation of and permit transfer for the Pike County Environmental Enterprises Wastewater Treatment Plant (WWTP).

The facility was originally constructed in 1984, with the original Part II Permit issued in 1983. The plant, located outside Matamoras, PA in Westfall Township, Pike County, exclusively accepts and treats hauled waste (residential septage and municipal WWTP solids). A separate collection and conveyance system does not exist; all wastes are trucked in. The plant receives hauled waste from Pike County, PA; Sussex County, NJ; and Orange and Sullivan Counties, NY, and then it discharges treated effluent to the Delaware River under its National Pollutant Discharge Elimination System (NPDES) Permit. It is allowed to treat and discharge an annual average daily flow of 0.100 MGD, with an actual capacity of 0.149 MGD.
