American Water, MWH to Study Disinfection for Water Recycling

The WateReuse Foundation has awarded American Water Works Company, Inc., an investor-owned U.S. water and wastewater utility company, a research grant to examine disinfection guidelines for satellite water recycling facilities in a joint research project with MWH.

Joseph Jacangelo, Ph.D., of MWH is the project’s principal investigator and Mark LeChevallier, Ph.D., of American Water is the co-investigator.

The project, valued at $634,394, will examine disinfection requirements for water recycling systems against California standards. In 2004, the U.S. Environmental Protection Agency issued updated guideline recommendations for water reuse, and each state has adopted regulations and guidelines differently, with California (under Title 22) recognized as one of the states with the most comprehensive set of high effluent water treatment process requirements.

“It is important to evaluate satellite treatment technology in terms of California regulations and measure performance findings against requirements from other states to determine methods of disinfection suitable for nonpotable water,” said LeChevallier, director of Innovation and Environmental Stewardship. “The outcome of this research could reduce the size and cost of chlorine contact basins and allow the water industry to implement more environmentally friendly technologies.”

American Water employs more than 7,000 professionals who provide drinking water, wastewater and other related services to approximately 15 million people in 32 states and Ontario, Canada. MWH is a multi-disciplined global team of program managers, business consultants, engineers, geologists, operators, scientists, technologists and regulatory experts all contributing toward providing clients solid solutions that reflect best practices in wet infrastructure knowledge, experience and innovation.
