Project Background In effectively "Transforming Wastewater to Resources," the District reduces local potable water demand via water recycling, generates onsite renewable energy via biogas utilization, and recovers valuable nutrients to improve soil health via land application and composting of biosolids. Biogas produced through anaerobic digestion of wastewater sludges is harnessed as the primary fuel source (60% biogas, 40% natural gas) for the 0.8 megawatt (MW) cogeneration system (i.e., one 1 MW internal combustion engine coupled with a 0.8 MW generator) at the onsite cogeneration system, which allows the District to meet approximately 50% of the WWTP power demand (85% with natural gas included). Waste heat from the engine is utilized on site to heat the anaerobic digesters to >98F. Because the existing cogeneration system, controls, and gas storage and conditioning system components are over 30 years old, the District's 5-year CIP includes the Project to replace the existing 0.8 MW cogeneration system and supporting biogas condition equipment and control systems. In February 2023, the District awarded a consulting services contract to Brown and Caldwell to provide engineering design services for the Project. Project design is currently underway with completion anticipated in summer 2024. This project is qualified for federal tax credits under the Inflation Reduction Action, which requires the project to be in construction by December 31, 2024. Project Description The project primarily involves renewing aging infrastructure in the District's cogeneration system to ensure continued effective and reliable conversion of biogas produced at the District' WWTP to electricity and useful heat for onsite use. Specific project tasks include: Demolition of existing gas treatment system, gas compressors and blowers, engine generator and ancillary equipment, HVAC fans, and electrical equipment Installation of new cogeneration system: internal combustion engine generator, auxiliary cogeneration heat recovery and wasting equipment, and engine exhaust emissions treatment equipment Installation of new digester gas condition equipment: H2S tanks and media, skid mounted digester gas conditioning system, chillers and pumps, electrical and control equipment, and piping Deadline to Submit Written Questions 5:00 pm PST, Wed, Feb 28, 2024.
