Patent ID: 8016548

Claim:
A water supply tunnel secondary purpose turbine electric power generator system which comprises: a) a water supply subsystem for a community that includes a water source at an elevation that is at least 300 feet above the mean altitude of said community, said water supply subsystem including delivery mechanism for water from said water source to said community that includes a gravity fed underground water tunnel being located, at least in part, upstream from said community, and, at least in part, being located under said community, said water supply subsystem having a plurality of riser conduits in said community connected to said gravity fed underground water tunnel, each of said plurality of riser conduits in said community connected to said gravity fed underground water tunnel, each of said plurality of riser conduits delivering water for said water source to said community at a pressure that is at least 100 psi in excess of desired water pressure delivered to community water lines; b) a plurality of water valving subsystems, each of said plurality of water valving subsystems connected to each of said riser conduits and including at least one safety valve to lower a water pressure of said delivered water and including a safety valve for shut-off and braking located downstream from a power generating turbine subsystem; and, c) a power generating turbine subsystem, including at least one water driven turbine located in each of said plurality of riser conduits.
