The City of Roseville and Brown and Caldwell announced a $19 million project to reduce nitrate discharges to water bodies and generate a renewable energy resource at the Dry Creek Wastewater Treatment Plant (DCWWTP) has received a 2020 Construction Management Association of America (CMAA) Project Achievement Award.

CMAA’s Project Achievement Awards program highlights projects that serve as an example to the industry and are true pinnacles of excellence and innovation, according to the press release. This year’s winners, consisting of 14 projects across sectors including commercial/sports/entertainment/hospitality, education, government, healthcare, transportation, and water/wastewater/utility, were recognized virtually at CMAA2020 on Oct. 16.

In the water/wastewater/utility (construction value less than $50 million) category, the team of the City of Roseville (owner), Brown and Caldwell (construction manager and architect/engineer), and Auburn Constructors LLC (general contractor) were recognized for seamlessly constructing cogeneration facilities and nitrate reduction improvements at the DCWWTP. 

A key challenge of 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 respectively. Nitrate reductions were required to facilitate compliance with new final effluent limitations for nitrate plus nitrite (NO3 + NO2) stated 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. Upon completion, the new facility allowed the City to meet the increasingly stringent effluent discharge requirements while utilizing a valuable renewable energy resource.

“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. “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.”

The 2020 CMAA Project Achievement Award marks a continuation of the facility’s recognition by industry peers having received a CMAA Northern California Chapter 2020 Project Achievement Award (public works over $10 million).

“We applaud the City of Roseville for their continued commitment to improving environmental health and sustainably maintaining vital infrastructure,” said Tim Hansen, Brown and Caldwell’s construction manager. “We are honored to have had the opportunity to contribute to the success of this important project and are grateful for the collaboration, dedication, and professionalism of the project team.”
