  • Project Name: Water Treatment Plant In-conduit Hydroelectric Station

    Location: San Bernardino County, CA

    Project Description: Domenichelli & Associates recently completed a 310-kW in-conduit hydroelectric station design for San Gabriel Valley Water Company. The design for the hydroelectric station contained two pump-turbine type generators and building structure, built adjacent to the existing Energy Dissipation Structure. Project on-line November 2013.

  • Project Name: Reservoir 7 In-conduit hydro design project

    Location: El Dorado County, CA

    Project Description: D&A provided design services for two small hydro projects (approximately 500KW each) located within an existing drinking water system in El Dorado County. These projects were identified during a study performed by a project team including D&A as the lead for evaluating project components, costs, and constructability. The design includes pumps as turbine (PATs) to replace existing in-line pressure reducing stations. Res 7 is at 80% design and recently has been granted a FERC Exemption and Res 3 is at 30% design. Both projects will require additional funding before moving to construction.

  • Project Name: Colfax In-conduit Hydroelectric Station

    Location: Colfax, CA

    Project Description: D&A provided a feasibility analysis for an in-conduit hydroelectric station at the outfall of a 24-inch conduit on a water supply canal system. Project flows ranged from 7 cfs to 35 cfs with a head of approximately 80 feet. A 190 kW cross flow turbine was selected as the preferred turbine. Limitations due to open canal debris handling and site access issues have placed this project on hold pending future developments.

  • Project Name: Sacramento In-conduit Hydroelectric Station

    Location: Sacramento County, CA

    Project Description: D&A provided a feasibility analysis for an in-conduit hydroelectric station at an existing pressure reducing station and storage tank facility. Project flows ranged from 5 cfs to 35 cfs with a head of approximately 210 feet. Multiple pumps as turbines (PATs) were selected to handle the wide range of flows for this 500 kW station. Included in the station design is an additional pump to supply water in the opposite direction during an emergency. This project is expected to receive grant funding for construction.

  • Project Name: Sly Park Dam In-conduit Hydroelectric Station

    Location: El Dorado County, CA

    Project Description: D&A provided feasibility level design plans, generation calculations, and cost estimates for a project located at the outlet works of Sly Park Dam. This project has a design flow of 100 cfs and a design head of 95 feet that can be regulated at the dam for consistency. The nameplate capacity of the project is estimated to be 680 kW. Due to Division of Dam Safety requirements and the schedule for FERC licensing this project will take some time to implement and is currently on hold.
