Our store is where you build your ReWater® system, the only greywater system to have gone through California’s State Water Resources Control Board’s State Revolving Fund analyses and found qualified for US EPA grants and loans.

Choose the components for your system and the current price will be shown at the bottom of this page.

A complete ReWater® system must have both a filter package and an irrigation package. These two packages are split here in our Store’s pricing pages so you have the option to buy the filter components when you need them early in the rough plumbing phase, and then the irrigation components when you need them later in the landscaping phase.

When you click “Submit”, a request is sent to ReWater to begin the purchase process for the selected products. This process includes email and/or phone conversations with ReWater about your filtration, landscape, and irrigation requirements to insure you’re getting what you need.

Please feel free to ask questions!

Filter packages

Irrigation and controller packages

When under contract, ReWater will prepare a ReWater® Code Compliance Form to help you obtain a permit. To complete that form, ReWater needs the following:

  1. A soil report for your project that explains the soil type and groundwater depth.
  2. A site plan (an existing plan can suffice) showing the following:
    • The greywater-producing building(s) in relation to the property lines
    • Any notable topography on your site, like slopes and cliffs
    • Any surface water, like streams and lakes
    • The preferred location of the filter unit, usually just outside the foundation
    • The sewer line and where the greywater tank overflow will connect to it
    • The potable water source connection to the system
  3. An approximate irrigation plan and the approximate square footage to be greywater irrigated.

We will do the calculations and answer everything in the order found in Chapter 15 of the California Plumbing Code and create a new plan page for this system. You then attach the completed form and new plan page to your permit application, pay the city or county’s permit fee, and submit that package for a permit. Your plan checker/building inspector can follow along in their code book and find our answers in the order presented by the code. This makes obtaining a permit much easier.
