EPA Opens Comment Period for Water Reuse Action Plan, WateReuse Initiates Member Survey

The U.S. Environmental Protection Agency (EPA) announced last week that it is seeking public input on the development of an action plan to accelerate water reuse nationwide. To facilitate input, EPA also released a Discussion Framework for Development of a Draft Water Reuse Action Plan, which provides background, context, and details on elements the Water Reuse Action Plan could address. EPA will accept public comments through July 1, 2019 online (search for Docket ID No. EPA-HQ-OW-2019-0174). The WateReuse Association is leading an effort to develop recommendations across water sector organizations, agriculture, industry and other stakeholder communities. To help guide our work, we invite members to provide responses to the WateReuse Survey for the EPA Action Plan. Please either submit your ideas directly to EPA and/or to WateReuse so that we can ensure their integration into our own comments. EPA will release a draft Water Reuse Action Plan for public comment in conjunction with the 34th Annual WateReuse Symposium in San Diego, California.

EPA Guidance Rejects the Need for Additional Permitting for Groundwater Recharge

Last week, EPA issued a guidance to clarify its interpretation of the Clean Water Act as it pertains to whether or not National Pollutant Discharge Elimination System (NPDES) permits are required for groundwater discharges. EPA’s conclusion is that the Clean Water Act does not require such permitting for releases into groundwater. The EPA guidance is relevant to an ongoing case taken up by the Supreme Court that could impact permitting requirements for recycled water groundwater recharge projects. In February 2018, the Ninth Circuit held that the County of Maui’s injection of highly treated effluent into an underground aquifer violated the CWA. The WateReuse Association joined with twelve other associations in submitting an Amicus Brief urging the Supreme Court to overturn the decision.

EPA to Hold Information Sessions on New Water Reuse Financing Opportunity

EPA is offering a series of information sessions for public and private borrowers interested in taking advantage of a new funding round through the Water Infrastructure Finance and Innovation Act (WIFIA) loan program. EPA estimates that the funding will create at least $6 billion in loan capital for water projects, including projects related to water recycling, which is one of three priority areas for the program in this round. The information sessions will include presentations from WateReuse members and provide information to prospective borrowers about the WIFIA program and this round of funding.

WateReuse Urges Revisions to Reuse Exemptions in “Waters of the U.S.” Rulemaking

The WateReuse Association last week submitted comments on the Administration’s proposed rule revising the definition of “Waters of the United States” and urged revisions to proposed exemptions for water recycling structures.    The revised definition includes several critical exemptions that WateReuse fought for during the initial 2014 rulemaking process, including exemptions for water recycling, wastewater treatment, and stormwater control activities from jurisdiction under the rule. However,  in our comment letter on the revised rule, WateReuse expressed serious concern over new language that limits these exemptions to upland applications and urged the Administration to remove this limitation. It is unclear when the Administration will release a final rule but WateReuse will track and report on developments as they occur.

Water Reuse in Bioenergy Production – A Pathway to Conservation and Resiliency (Webcast)
Join May Wu, Principal Environmental System Scientist with Argonne National Laboratory, for a webcast on the role of water reuse in bioenergy production. 11:00 am – 12:00 pm PT | 2:00 pm – 3:00 pm ET WateReuse Members: Free | Others: $49 Register Now! Production of bioenergy from a range of feedstocks and biorefining pathways requires a substantial amount of water for irrigation, conversion process, cooling, and steam generation. Because the feedstock varies with climate and soil regions, an increased production will have implications in the availability of regional and local freshwater resources across the U.S. It is critical to understand how fit-for-purpose water recycling can be used to conserve freshwater. This webcast presents findings from an Argonne National laboratory analyses of potential recycled water use to produce biofuels from conventional crops and algae and generate power by incorporating technology, climate, and geospatial-temporal components. Findings suggest a significant potential of producing advanced biofuel while doubling the amount of recycled water in use nationally. Results from this project support informed decision-making and strategic planning for water sustainable bioenergy development.

Presenter

May Wu is a principal environmental system scientist at Argonne National Laboratory. Her research interests are water resource use, water quality, and wastewater management in the production of biofuels and conventional energy.

The Southwest U.S. is challenged by freshwater scarcity and salt accumulation in its watersheds. A significant contributor to salt loading in urban sewersheds 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.

Presenter

Eric Dole is a senior project manager at Garver where he serves as the Water and Energy Practice Leader.  He specializes in delivering sustainable infrastructure solutions through optimized hydraulic systems and optimized treatment processes.  In 2019, Eric was selected for the Water Research Foundation’s 12-person Energy Advisory Committee where he advises the group on energy efficiency and process optimization projects.

Eric was one of the world’s first water professionals to be certified as a Pump Systems Assessment Professional (PSAP) through the Hydraulics Institute, which allows him to set the standard for pump systems assessments and optimization techniques, leading to energy efficient and reliable systems.  His process mechanical expertise can be seen in his patented designs for two zero liquid discharge brine management systems, of which one was awarded the 2011 AZ Water Reuse Project of the Year Award and the other was selected for RO concentrate treatment in the Bureau of Reclamation Desalination Pitch to Pilot Research Project that started in September 2020 and is scheduled for commissioning in May 2021.

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.
