WASD's Cogeneration Facility improvements win "Best Overall" award for DBIA Florida Region

MIAMI (October 22, 2015)

The Miami-Dade Water and Sewer Department’s (WASD) South District Wastewater Treatment Plant’s (SDWWTP) Cogeneration facility improvements won the Design Build Institute of America’s (DBIA) Best Overall award in the Water/Wastewater Category for the Florida Region Design-Build Awards.

The existing cogeneration facility at the SDWWTP was constructed by Poole & Kent in 1991 and generates electricity from digester gas produced on-site. Studies completed by the County indicated that methane gas produced at the nearby landfill could provide up to 30 percent of the energy used at the SDWWTP through additional cogeneration, thereby reducing the facility's reliance on fossil fuel-derived energy. It is anticipated that the project will have the potential to produce up to 63,800 kW per day.

“Using all biogas provides a cost savings of approximately $650,000 per year per 2 megawatt cogeneration unit operating on biogas and natural gas,” said WASD Director Lester Sola. “Not only would we be less dependent on purchasing electricity, thus realizing a cost-savings, but utilizing the methane gas in this method is also an environmental benefit.”

The awards were presented Oct. 8–9 during the 2015 DBIA Florida Region Annual Conference in Orlando, FL.

It is the priority of the Miami-Dade Water and Sewer Department to provide safe, reliable service to its customers. For additional information about Department services and programs, visit
