The project intends to install a small hydroelectric generating powerhouse on the outfall of the Nevada City Wastewater Treatment Plant (WWTP). To do this, the project will install approximately 150 linear feet of 8" diameter PVC pipe, including two concrete pipe supports, a small platform and powerhouse to house a small turbine and hydroelectric generator. The outfall pipe from the generator will also be 8" diameter, will be anchored to existing boulders and will discharge directly into Deer Creek. An extension pipe (approximately 37 linear feet 12" diameter PVC pipe) will be added to the existing WWTP outfall pipe to bypass the new powerhouse location. This project uses existing effluent flows and simply reroutes the flows to parallel pipe that will discharge in the same permitted (CVRWQCB) location in the creek. All excavation occurring within the riparian will be completed by hand. An existing primitive path will be improved, entailing approximately 20 linear feet of minor trail grading and construction of approximately 45 linear feet of elevated wood walkway and stairs.
