Greywater describes diversion of water outflows from dish washing, laundry machines, showers and bathtubs to be used for irrigation of yards and our landscape. Laundry machines are the most common greywater source. Graywater is very different from Black Water. Black water is human and animal wastewater, and is under no circumstances recommended or fit for any type of irrigation in an urban environment.
Graywater systems are legally subject to the Huntington Beach plumbing code, which reflects the CA plumbing code. The California Building Standards Commission (BSC) adopted new code language for the California Plumbing Code, Title 24, Part 5, Chapter 16A, Part I, that took effect August 4th, 2009. A permit is not required if a single source greywater system is installed, existing plumbing is not altered and these 12 guidelines below are followed.

There are many diverse opinions on graywater, favorable and non-favorable, and its place, use and value in our society. As Southern California grapples with the reality of water shortages and as climate variability may decrease future snowfall in the Sierra Nevada mountains, the use of safe and legal greywater systems reduces the demand for precious potable water, stretching our water resources while providing extra irrigation water to our yards and gardens.
* If you are are thinking about installing a greywater system, remember to only use biodegradable soap that contains no salt.
