With all the media covering California’s historic 4 year drought, Revolution has been getting a lot of inquiries about greywater systems. The short answer is yes, it is legal to use greywater at your home. In 2010, California adopted new greywater regulations to help residents conserve water. While some types of greywater systems still require a permit, those which utilize spent washing machine water are one of the easiest to install and no permit is required as long as you adhere to the following guidelines:
Three way valve to allow diversion to sewer or landscape
No connections between greywater and potable water supply
Greywater must be contained onsite with no ponding or runoff
Greywater must be discharged below 2’’ of mulch
Water used for washing diapers or other infectious garments must be diverted to sewer
Greywater may not contain hazardous materials
The design must be consistent with the CA plumbing code
An operation and maintenance manual must be provided to the owner and all subsequent owners/tenants
If you are interested in incorporating greywater into a comprehensive landscape overhaul, give Revolution Landscape a call or fill out an inquiry through our contact us page and someone will be in touch shortly to discuss your project!
