Device for recycling rainwater for domestic use - comprises storage tank collecting water from pipe system, with valve-controlled outlet to pump-assisted distribution conduit system

摘要

A rainwater collection pipe (21) delivers water to a storage tank (22), which has an outlet pipe (23) controlled by a three-way valve (30). The outlet pipe delivers the water to a primary distribution pipe system (13) of a water supply. A detector (24) measures the level of water in the storage tank and controls the actuation of the three-way valve. A pump (40) is located in the tank outlet pipe to deliver water to the distribution pipe when the level of water in the tank is measured as being below a predetermined level. An overflow system (26) is also fitted to the tank. ADVANTAGE - Continuous supply of non-drinking water, with limited dependence on water level.
