Abstract

A waste water recovery and utilization system that converts waste water including gray water, liquid sewerage waste and solid macerated sewerage waste to steam and to electricity comprises a gray water tank, a sewerage tank, a steam generator with a gray water crucible for vaporizing the gray water and a sewerage crucible for vaporizing the liquid sewerage waste and for incinerating the solid macerated sewerage waste thereby generating steam for space heating. A variable speed injection pump cooperates with the gray water tank, with the sewerage tank, with the gray water crucible and with the sewerage crucible. Condensate is collected in a condensate tank. The system is operable on multiple fuels, including hydrogen and oxygen provided by the system, natural gas and liquid propane gas. Alternate energy including solar, wind and mechanical, supply electrical power to an electrolysis machine when conventional electrical energy is to be conserved.
