As unappetizing as it may sound, grey water is useful stuff. OasisDesign.net defines it as such: “Any water that has been used in the home, except water from toilets, is called grey water. Dish, shower, sink, and laundry water comprise 50-80% of residential ‘waste’ water. This may be reused for other purposes, especially landscape irrigation.” The benefits of grey water recycling include:

Lower fresh water use

Less strain on failing septic tank or treatment plant

Grey water treatment in topsoil is highly effective

Ability to build in areas unsuitable for conventional treatment

Less energy and chemical use

Groundwater recharge

Plant growth

Reclamation of otherwise wasted nutrients
