17. Processing the primary clarifier effluent is one of the most energy intensive steps in wastewater treatment Primary effluent filtration can cost effectively reduce aeration power consumption and enhance biogas production at wastewater treatment plants. Linda County Water District in Olivehurst Primary Effluent Filtration to Increase Energy Recovery in Wastewater Treatment Victor Valley Wastewater Reclamation Authority Zero Net Energy Wastewater Treatment Project Dublin-San Ramon Service District CASCADE Clean Energy System for Water and Wastewater Pilot-scale bioreactor at the wastewater treatment plant to demonstrate CASCADE Clean Energy system Increase methane production using customized bacteria matched to the organic content of the wastewater. Retrofitted and installed a novel technology at the to increase biogas production. Biogas production was also enhanced by co-digestion of oils and grease and municipal sludge. The resulting biogas is used to generate 1.6 MW –enough to cover all the electricity needs of the treatment plant and provide excess for sale to the grid. Completed Municipal Wastewater Treatment

20. Water Energy Technology Program The purpose of the WET program is to fund emerging water and energy saving technologies that meet the following criteria: – Displays significant water savings, energy savings, and greenhouse gas emission reductions. – Demonstrate actual operation beyond the research and development stage. – Document readiness for rapid, large-scale deployment (but not yet widely deployed) in California. Subscribe to the WaterSaver List Serve at www.energy.ca.gov/wet/ www.energy.ca.gov/wet/ For further information, e-mail: wet@energy.ca.govwet@energy.ca.gov Program kick-off is expected summer 2015.

21. ARFVTP Projects East Bay Municipal Utility District (ARV-10-022) $1,000,000 to develop a process to convert fats, oil, and grease (FOG) to biodiesel at wastewater treatment plants. City of San Mateo (ARV-14-028) $2,450,000 to sustainably and cost- effectively produce low carbon vehicle fuel from the unused digester gas that is generated at the City of San Mateo’s wastewater treatment plant (WWTP). Cal Poly Corporation (Cal Poly State University, San Luis Obispo – ARV-10- 027) $250,000 to conduct and assess pilot-scale production of low-cost, oil-rich algae biofuel feedstock using wastewater nutrients. 21
