Document Description
The Delta Diablo Sanitation District proposes to install solar photovoltaic (PV) electricity generating systems at its wastewater and recycled water facilities. The proposed PV systems would be installed within the following locations at the District's treatment facility: the North Field, Scrap Area, and Plant Operations Center roof and parking lot. The systems would be comprised of PV modules and array support structures. The modules would be either ground-mounted and/or roof-mounted and may include a single axis tracking system to ensure optimum angles for solar energy collection. The proposed solar energy systems would generate over 1,400,000kWh annual. The power would be used by the existing recycled water facility. The purpose of this project is to improve energy efficiency and reduce dependence on fossil fuel-generated energy. The proposed improvements would reduce the District's unit energy costs, reduce the District's greenhouse gas emissions, and provide a long term power supply.
