CODE COMPLIANCE FORM

When under contract, we provide you with our Code Compliance form. Our form takes your plan checker through the entire California greywater irrigation code, Chapter 15 of the California Plumbing Code. Proceeding in the order the code is written, it explains how your building, landscape, soil, and ReWater® system meet every criteria for a permit. To complete that form, we need:

1) your site plan, showing the building in relation to the property lines,

2) the location of the potable water source,

3) the location of the wastewater connection,

4) your soil report, and

5) an approximated drawing and square footage of the future greywater-irrigated landscape.

If your residence meets the code criteria, and almost all do, you should be able to obtain a permit anywhere in California. This can help you in other states that use the UPC for a plumbing code too.

California’s greywater code is extremely difficult to navigate if you haven’t personally gone through the permit process before. Most people find our Code Compliance form very helpful in obtaining a permit.

PERMITS

You need a permit if you want a robust and legal system to reuse water efficiently, satisfy mandates, and increase the value and resale value of your residence. ReWater’s Code Compliance form was created from our decades of experience with permitting and makes obtaining a permit much easier.

ARIZONA

Under Arizona state law, single-family homes producing less than 400 gallons of graywater per day do not need a permit for a greywater irrigation system. The exception is when a local jurisdiction has passed an ordinance requiring one. Unfortunately most big cities there have passed some type of ordinance requiring a permit. Multi-family, Commercial, and institutional systems always require a permit even in Arizona.
