Technical Tour
Metropolitan Biosolids Center (MBC)Wednesday, August 4, 1:00 pm – 3:30 pm
This award-winning, energy self-sufficient $250 million City of San Diego facility opened in 1998, replacing the Fiesta Island Sludge Processing Center. It services 2.2 million customers and generates about 180 MGD of wastewater and 125 tons of de-watered bio-solids per day. Situated on 39-acres, the 8.4 MGD biosolids treatment facility was designed to thicken and stabilize primary and secondary sludge from the City's North City Water Reclamation Plan and Point Loma Wastewater Treatment Plant digested bio-solids, which are generating 180 MDG of wastewater flow. Once stabilized, the biosolids are trucked off site for use in soil amendment and to landfills for beneficial use and landfill. Methane from the adjacent Miramar Landfill and from MBC digesters fuel two power engines that provide all the facility's electricity, heating, and cooling needs. The facility has won awards for fiscal and energy effectiveness and aesthetic design.
Tour fee: $30. The tour fee includes a boxed lunch and bus transportation to and from the facility. Buses begin loading at 12:30 pm.
