The project will study the biological components of water in reclaimed water systems, or those where wastewater is treated and reused for a number of environmental purposes, such as irrigation and grounds maintenance.

“Water is a precious natural resource, and one that is essential to life,” says Mark LeChevallier, director of innovation and environmental stewardship at American Water. “Reclaimed water systems prevent pollution, enhance the environment and promote sustainability.” The American Water-WateReuse Foundation project will provide practical data for understanding how microbial regrowth in reclaimed distribution systems alters effluent microbial water quality - and how to control this regrowth.

The end report will document cost-effective strategies to reduce the risks of regrowth in reclaimed water systems throughout the country.
