There is a grey water supply and purification system comprising a storage reservoir (2) for purified grey water, a storage reservoir (3) for contaminated grey water and a grey water purification tank (1) which is connected between reservoirs (2 and 3). There is a pump and conduit system (28, 33) for the supply of purified grey water from the reservoir (2) for usage such as hand basins (8), bath/shower (9), laundry (10) and toilet (13). There is a conduit system (11) for discharging contaminated grey water from such usage (other than toilet usage) to the reservoir (3) and pump and conduit system (17, 17A) for supplying grey water to the purification tank (1). There is also a pump (26) and conduit (27) for replenishing the reservoir (2) with purified water from the tank (1). The pumps are controlled by a microprocessor (24).
