Gray Water Systems

greysystemUnder State regulations, graywater is defined as untreated wastewater that has not been contaminated by toilet waste or unhealthy bodily wastes. Graywater includes wastewater from bathtubs, showers, bathroom washbasins, clothes washing machines, and laundry tubs, but does not include wastewater from kitchen sinks or dishwashers.

A graywater system uses graywater for subsurface irrigation and may include tanks, valves, filters, pumps or other appurtenances along with piping and receiving landscape. Graywater shall not be used in spray irrigation and shall not be allowed to pond, runoff or be discharged directly into or reach any storm water system or any surface body of water. Additionally, graywater shall not be used to irrigate root crops or edible parts of food crops that touch the soil.
