Abstract

The present invention relates to a method and apparatus for treatment of waste water, in particular black and grey household waste water. A water treatment apparatus for the treatment of household waste water is disclosed, with the apparatus comprising a plurality of chambers for receiving the waste water, the chambers arranged to allow the waste water to undergo a series of treatments to produce a treated effluent, wherein the plurality of chambers includes at least one anaerobic chamber adapted to treat said waste water with anaerobic processes, and at least one aerobic chamber adapted to treat said anaerobically treated waste water with aerobic processes.
