The cities of San José and Santa Clara as well as TPAC members celebrate the completion of a new CHP project with a virtual ribbon cut. The four-year design-build project is a key milestone in the $ 1.4 billion 10-year capital improvement program (CIP) to modernize the San José-Santa Clara (RWF) regional wastewater facility. The RWF is the largest modern wastewater treatment plant in the western United States and has been operating continuously since 1956.

The CIP team overcame pandemic-related challenges such as carrying out final tests of the devices virtually with technicians from providers in Germany and successfully delivered the 114 million dollar project for the CHP plant, which improved the RWF’s energy and heat generation. Using a combination of biogas, which occurs naturally during wastewater treatment, and natural gas, four new motor-generators will produce up to 12.5 megawatts of electricity to supply the RWF with electricity. The project replaces existing CHP engines that have been worn out from non-stop use for over 35 years.
