Rule 4 Discharges of Greywater

The discharge of greywater onto or into land is a Permitted Activity provided the discharge

(a) does not exceed a maximum daily volume of 2000 litres;

(b) is more than 20 metres from any surface water body, farm drain, water supply race, or the coastal marine area; and

(c) does not cause ponding on, or runoff from the disposal area.

Explanation. This rule applies to greywater only, and does not apply to any discharge that contains human sewage. Greywater (see Section 3 of the Plan) is “the wastewater from sinks, basins, baths, showers and similar appliances, but not including any toilet wastes. Also known as sullage.”
