Frequently Asked Questions
Yes, greywater recycling is legal and encouraged in Los Angeles under the California Plumbing Code. Simple laundry-to-landscape systems often require no permit, while more complex systems involving pumps or filtration require city permits to ensure health and safety standards are met for Southern California residential properties.
Homeowners in Los Angeles can typically recycle up to 50% of their indoor water usage for outdoor irrigation.
