AWE Survey on Member Research Priorities
The Alliance for Water Efficiency is surveying its membership to identify and prioritize research interests and needs. The results of this survey will be utilized by AWE’s Water Efficiency Research Committee to direct its efforts. Please participate and help AWE better serve its members. We estimate it will take less than 5 minutes to complete. The survey will be live through Friday, September 20. Take the survey here.
AWE Advocacy Efforts
AWE continues to work on federal issues related to funding the WaterSense program and getting water efficiency and green infrastructure rebates to be tax exempt.
WaterSense: Congress is back in session and working on appropriations. It now appears quite likely, if not certain, that they will not complete action on all 12 appropriations bills by the upcoming Sept. 30 deadline (the end of the federal fiscal year). While the House has passed all 12 bills, including the spending bill for Interior/EPA containing instructions to continue WaterSense, the Senate has passed no spending bills. In fact, the Senate Appropriations Committee will this week mark up the first four appropriations bills (the FY 2020 spending bills for the Department of Defense; Energy and Water Development; State and Foreign Operations; and Labor, Health and Human Services and Education). No word yet on when they will get to Interior/EPA.
Even if the Senate moves promptly on a bunch of appropriations bills, their versions will be significantly different from the House bills. So there will likely be extensive conference committee deliberations to get things in line. It seems now likely that bipartisan leadership will agree on a continuing resolution that extends the deadline for new spending measures until Thanksgiving. We will continue to monitor any committee reports to ensure that instructions regarding WaterSense remain intact. Even though we were successful in getting WaterSense authorized, getting actual money into that line item has proved to be more difficult than we expected.
Tax-exemption for rebates: AWE sent a support letter signed by 75 organizations to support HR 2321, a bill to make water efficiency and green infrastructure rebates tax exempt. Unfortunately, there does not appear to be any movement in the House on a “green” tax bill that might include the provisions of HR 2321. The only environment-related tax bill given any chance this year is a proposal to expand the tax credits for electric vehicles. House leaders will likely try to include a tax-extenders bill as part of year-end spending bills, but that would not at this time include any tax-law changes—just renewal of several provisions that have expired or are about to expire.
AWE will continue to push this issue and we will keep you all informed.
National Academies of Sciences, Engineering, and Medicine release Management of Legionella in Water Systems
New reports of Legionella seem to pop up nearly every day. Indeed, research shows that instances of Legionella increased more than five-fold from 2000 to 2017. As Legionella is waterborne, water industry professionals have an indispensable role to play in the safe management of water systems and must stay apprised of developments regarding Legionella. To this end, the National Academies of Sciences, Engineering, and Medicine recently released a comprehensive report which surveys the “state of the science” on the biology of Legionella, the role of water systems in its transmission, quantifying illness cases, strategies for preventing and controlling the spread of Legionella, and policy issues relating to the management of this multidimensional issue. A webinar launching the report can be found here. This report has crucial takeaways for the water industry.
Threshold of Legionella concentration: The report authors recommend establishing an “action level,” or a threshold of Legionella concentration that triggers action to remediate the system, of 5 x 10^4 Colony Forming Units (CFU)/Liter. At this level of concentration, “serious concern” is warranted. For facilities such as hospitals and skilled nursing facilities where users may be more susceptible to Legionella, the action level may be reduced.
Water temperature: Legionella grows optimally at water temperatures between 25° and 43°C. The report authors recommend that buildings maintain hot water heater temperatures above 60°C, with water temperature to distal points above 55°C.
Unintended consequences of water and energy conservation measures: The report authors identify the fact that water and energy conservation measures may have unintended consequences that may contribute to Legionella growth. These unintended consequences may include increased water age, less effective scouring of pipes, and water temperatures too low to effectively combat Legionella growth. In addition to recommendations on water temperature, the report authors recommend disallowing low-flow water fixtures in facilities where users may be vulnerable to Legionella, including hospitals and skilled nursing facilities. They also recommend amending green codes and green certification criteria for buildings to account for the risk factors of Legionella outlined in the report. Further research is required, but the authors suggest that water and energy conservation are still possible as long as unintended consequences are addressed.
Cooling towers: The report authors recommend that facility managers ensure their existing cooling towers operate safely, with appropriate temperatures and disinfectants. Also recommended is further research into new cooling tower systems that operate at temperatures high enough to prevent growth of Legionella.
Policy recommendations: The report authors offer policy recommendations to help manage Legionella, including implementing required Legionella monitoring in facilities receiving funding from the Centers for Medicare & Medicaid Services, required registration of cooling towers, and required water management plans in public facilities.
The goals of safe management of Legionella and conservation are not mutually exclusive but, as this public health issue continues to develop, water industry professionals must remain abreast of the science and prepare to account for Legionella in their systems. AWE President and CEO Mary Ann Dickinson will be speaking at the 2019 Legionella Conference on Thursday, September 12th about AWE’s ongoing research into cooling technologies.

Energy and Water Research Integration Act of 2019 Passed in House and Referred to Senate Committee on Energy and Natural Resources
Research from the “DOE has found that 196 billion gallons of water per day are withdrawn for thermo-electric cooling to support power generation, in comparison to 44 billion gallons of water per day that are withdrawn for public supply.” In addition, River Network estimates in The Carbon Footprint of Water that an equivalent to 13 percent of the U.S. electricity consumption is water-related.
Despite these known and accepted connections between water and energy, work remains to be done to reduce the consumption of energy and water together. Occasional projects at the utility level have shown what can be done when these resources are considered together. AWE and the American Council for an Energy-Efficient Economy (ACEEE) awarded selected programs for exceptional efficiency programs that save both water and energy.
If passed, the Energy Water Integration Act of 2019 has the potential to advance water and energy efficiency through a joined approach to accelerate the rate at which we integrate the two efficiency fields. The bill calls for the Department of Energy to consider water in energy research, development, and demonstration programs by advancing energy and energy efficiency technologies with water conservation and efficiency in mind, considering the impact of climate change on water supplies and quality, and improving the understanding of the water-energy nexus. Read the bill language here.
While there are plenty of viable research options, AWE and ACEEE developed a white paper detailing recommendations for future research opportunities after analyzing what research already exists. For more information on this topic, check out these resources.
