WateReuse Submits Letter on U.S. EPA’s PFAS Regulatory Determinations

The WateReuse Association submitted a letter in response to the U.S. Environmental Protection Agency’s (EPA) determination to regulate certain Per- and Poly-fluoroalkyl Substances (PFAS) in drinking water. WateReuse supports the timely establishment of a federal Maximum Contaminant Level (MCL) for perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) in accordance with the established regulatory process under the Safe Drinking Water Act, and asks that regulatory decisions be based on science, tied to public health and environmental risk, and informed by an understanding of treatment technologies. The letter urges EPA to consider the guiding principles developed by WateReuse in the fall 2019.

California: WateReuse California and CASA Urge Increased Funding for CA CWSRF

Last week, WateReuse California and the California Association of Sanitation Agencies submitted a letter to the State Water Resources Control Board (SWB) urging increased funding for the California Clean Water State Revolving Fund (CWSRF). In a comment letter on the Intended Use Plan for the CWSRF, the two organization asked for a funding a level commensurate with California’s economic standing and significant need for infrastructure, job creation, and water supply investment. Over the last three years, the amount of funding has steadily declined, to a low of around $200 million in FY 2019-2020. Read More.

California: San Diego Water Board Unanimously Approves Potable Reuse Permit

The City of San Diego can now add purified water to the Miramar Reservoir for Phase 1 of the Pure Water San Diego program. The San Diego Water Board unanimously adopted an order that grants a National Pollutant Discharge Elimination System (NPDES) permit. The permit is the first of its kind in California, and contains limits on what can be discharged, monitoring, and reporting requirements to ensure water quality and public health. Read more about the Phase 1 project.

California: South County Ag Program to Provide Recycled Water for Agriculture

WateReuse Association member Regional San has selected a team of Brown and Caldwell and Carollo Engineers to develop a program to irrigate crops with recycled water instead of groundwater. The $375 million South Sacramento County Agriculture & Habitat Lands Recycled Water Program is one of the largest agricultural reuse projects in the country. It will irrigate up to 16,000 acres of permanent agriculture and habitat conservation land with up to 50,000 acre-feet per year of water. This massive reuse will lessen the dependence on the over drafted groundwater in the southern part of Sacramento County. Read More.

Florida: Crystal River Looks to Increase Recycled Water Sent to Duke Energy

To minimize the impact of wastewater discharges on the local watershed, the City of Crystal River is looking to increase the amount of reclaimed water that it sends to two Duke Energy coal facilities. The city currently provides about 750,000 to 800,000 gallons a day of reclaimed water to the coal plants, which decreases Duke Energy’s reliance on groundwater and gives the city a needed end use for its reclaimed water. The city is negotiating an offer to send additional reclaimed water to the company’s Citrus Combined-Cycle Natural Gas Plant. Read More.

Research Update

Researchers Find Current Practices in Water Treatment Protect Public Health in the Age of COVID-19

Do our existing water systems adequately protect public health in the age of COVID-19? An editorial by Brian Pecson of Trussell Technologies, Daniel Gerrity of the Southern Nevada Water Authority, and others in Environmental Science: Water Research & Technology provides perspective on what is known and what is being learned through current research. The 15 contributing scientists and engineers recommend that the industry leverage past findings on similar coronaviruses and the growing body of research on SARS-CoV-2 to estimate its impact on our water systems. To date, the preliminary findings provide reassurance that SARS-CoV-2 is unlikely to reset the requirements for public health protection in the water industry. Current requirements for robust, multiple-barrier treatment systems appears to be a solid foundation for the control of emerging and future pathogens as well. Read More.

NACWA White Paper Offers Funding, Financing Options to Address COVID-19 Economic Challenges

In a newly released white paper, the National Association of Clean Water Agencies (NACWA) estimates that the clean water sector could face an economic impact of approximately $16 billion from the coronavirus pandemic. The white paper outlines various funding and financing options the federal government could take to help municipal clean water utilities cope. Without direct federal funding, NACWA asserts that clean water agencies will see significant revenue challenges from the economic disruption that will exacerbate existing affordability challenges and affect future investments.

Process Interrupted: Using BOR Funded Desalination Research to Evaluate an Innovative Process Train to Halt the Salt Accumulation in a Sewer-shed from Cooling Towers while also Promoting a Circular Economy.

Presenters

  • Eric Dole, PE, PSAP, Garver USA
  • Michael Watts, PhD, Garver USA
  • Yuliana Porras-Mendoza, US Bureau of Reclamation

The Southwest U.S. is challenged by freshwater scarcity and salt accumulation in its watersheds. A significant contributor to salt loading in urban sewer-sheds are the many industrial and commercial cooling towers that dot the landscape. These towers are very effective at cooling in arid environments; however, they use scarce freshwater resources to absorb heat through evaporation while accumulating the salts and minerals that must be discharged as blowdown.

Garver was selected by the Bureau of Reclamation’s Desalination and Water Purification Research Program Pitch to Pilot to research a novel treatment train that will reduce the amount of salt discharged from industrial cooling tower blowdown.

Garver’s zero liquid discharge, membrane desalination treatment train is estimated to remove more than two tons of salt from the 600 ton cooling tower blowdown and saved approximately 200,000 gallons of make-up water from the potable water supply over the eight-month field-testing portion of the pilot study.  The reduction of salt discharged to the sewer will benefit the local wastewater treatment plants and the local watershed, while also improving the water quality of the cooling towers with a low energy intensity treatment train.

This presentation will address the BOR Desalination Pitch to Pilot Program, the thought process behind the EC, UF, GAC, RO with VAED concentrate management treatment train and report on commissioning efforts to date.

In this webcast, our presenters will introduce how digital platforms that include artificial intelligence (AI) and machine learning (ML) can be used to improve asset management strategies and operational efficiencies, as well as enhance source control, validate unit process performance, predict product water quality and make sound decisions for assessing suitability of product water for human consumption.

The data collected from pilot and full-scale potable reuse treatment trains have been used to develop artificial neuron networks as part of an ML platform. The platform clearly demonstrates that ML can be used to predict, for example, the product water total organic carbon (TOC) concentration of a pilot advanced treatment facility and the specific fluxes on the third stage of a full-scale advanced treatment facility as the feed quality and operating conditions are changed.

The methodology used and model outputs will be discussed during the webcast. The presenters will also examine how we can couple AI/ML concepts with the Internet of Things (IoT) and next generation of the SCADA systems to operate and maintain assets efficiently while significantly enhancing public and regulatory confidence in potable reuse projects.
