Codes and Forms

Code and Compliance Forms

California Code | Arizona Code

When under contract with a ReWater customer, we provide that customer with a Code Compliance form that takes their inspector through the entire California greywater irrigation code, Chapter 16 of the California Plumbing Code, in the order the code is written, explaining how your home, its landscape, and the ReWater® system meet every criteria for a permit. To complete that form, we will first need your site plan, showing the building in relation to the property lines, your soil report, and an approximated drawing of the future greywater-irrigated landscape. If your home meets the code criteria, and almost all do, you should be able to obtain a permit anywhere in California or any other state that uses the UPC for a plumbing code.

Because California’s greywater code is difficult to navigate if you haven’t personally gone through the permit process before, many people have found our Code Compliance form very helpful in obtaining a permit. ReWater worked a total of over 7 years during three different legislative processes with the California Department of Water Resources and Department of Health Services and numerous local agencies, environmental groups, and other water recycling businesses to write the original and second state greywater code. In 2009 – 2010, we then worked with California’s Department of Housing and Community Development on Chapter 16, and in 2013 again, and have adjusted our Compliance Form accordingly. If you’re looking for a legal system to increase the value and the resale value of your home, you need a permit in most states, and ReWater’s code compliance form certainly makes the process easier.

A special note for people in Arizona: Single-family homes producing less than 400 gallons of greywater per day do not need a permit for a greywater irrigation system unless some local jurisdiction has passed a more restrictive ordinance. Multi-family, Commercial, and institutional systems do require a permit.
