"Technology plays a key role in nurturing a healthy urban living environment. The USDN workshop provided us the opportunity to share our experience deploying the New York City Registration Portal with participating governments and provided attendees with a roadmap for a successful program implementation," said Hrair Achkarian, president and CEO of GroveWare Technologies Inc., the software firm that developed New York City's cooling tower registration system.
Registries can also be a crucial tool to measure key sustainability performance indicators, aiding jurisdictions in evaluating the effectiveness of a building's water conservation plans and identifying areas for improved energy efficiency.
Cooling towers can be a significant source of water demand for a building, representing 20-50 percent of total water usage, according to the report, which added that poor management practices result in millions of wasted gallons of water per year in a single cooling tower. In Los Angeles alone, for example, it is estimated that more than two billion gallons of water per year are wasted, according to the report.
The report reflects information collected from participants in webinars on April 15, May 17 and July 16, 2019; as well as a two-day workshop conducted Sept. 9-10, 2019, at the annual Legionella Conference in Los Angeles co-hosted by NSF Health Sciences and the National Environmental Health Association. NSF and GroveWare also conducted interviews with several agencies participating in the USDN project to gain insight into what criteria and factors were critical to their public health and sustainability missions.
NSF Health Sciences is presenting the findings of the report at upcoming events, including the AWWA Sustainability Conference in March 2020 in Minneapolis, AWWA ACE in June 2020 in Orlando and the National Environmental Health Association annual meeting in July 2020 in New York City. Public agencies interested in receiving a training/workshop on cooling tower registration systems, Legionnaires' disease outbreak response investigations and/or sustainability strategies for cooling tower systems should contact NSF Health Sciences LLC's building water health team at 734-769-8010. The report with a full list of participant cities is available on the USDN and NSF websites.
