Abstract

A greywater recycling system comprises a low level sump (10) for holding greywater. The greywater is disinfected by means of a chemical solution which is fed from a special mixing tank (18). The chemical solution is introduced into the sump (10) via a special metering device (25). Greywater drains into the sump (10) via a special filter (16). The filter (16) takes solid particles out of the greywater and has a special back-wash cleaning facility. A specially designed drain valve (17) is used for operating the filter (16).
