ROSEVILLE, CALIF. — The California City of Roseville and the environmental engineering and construction firm Brown and Caldwell have announced that the city’s $19-million water treatment project has received a 2020 Construction Management Association of America (CMAA) Project Achievement Award.
The project saw Brown and Caldwell engineering a plan to reduce nitrate discharges to water bodies and generate a renewable energy resource at the Dry Creek Wastewater Treatment Plant (DCWWTP).
The CMAA’s Project Achievement Awards program honours projects that serve as examples of excellence and innovation, explained an Oct. 19 statement. This year’s winners were recognized virtually at the CMAA 2020 event on Oct. 16.
Roseville (owner), Brown and Caldwell (construction manager and architect/engineer) and Auburn Constructors LLC (general contractor) were recognized for the project. A key challenge for the team was to ensure continuous operation of the facility to maintain effluent quality discharged to Dry Creek where adult and young Chinook salmon migrate upstream and downstream, the release stated.
Nitrate reductions were required to achieve compliance with new final effluent limitations for nitrate required in the National Pollutant Discharge Elimination System Waste Discharge Requirements Order R5-2014-0049. The addition of cogeneration provides electrical power to the DCWWTP, offsetting utility usage and bills, and delivers heat for the plant’s digester tanks.
“Projects like these require tremendous tenacity, teamwork and constant collaboration of the project team,” said Ken Glotzbach, assistant wastewater utility director for the City of Roseville, in a statement. “We are proud of the hard work it took to make this project come to fruition. It truly is testimony of the team’s mission of creating conditions that help towards environmental stewardship and the protection of public health.”
