Abstract: A drought relief system employs waste water as normally discharged from an appliance into a plumbing drain. A dual valve assembly is mounted in series within an existing appliance discharge line, usually exteriorly of the appliance and includes a first valve allowing for the distribution of waste water to the normal discharge line. By shutting off this first valve and opening a second valve, waste water is directed into a drought diversion conduit passing through the building wall and communicating with an appropriate distribution line. The latter may comprise a single conduit or a manifold network of conduits such as perforated pipes or hoses and thus permits utilization of water that otherwise would be discharged into the user's septic system or municipal waste system.
