Single-Family ReWater Automatic Filter System
This model RWAF is our most popular single-family filter system due to its convenient automatically backwashing sand filter.
This filter system satisfies all 2016 codes in California and most other state codes. Many jurisdictions still prefer this system due to its use of a reduced pressure principle device (RP) on the water supply that can’t be easily cross connected. It is typically used where there’s a lot of greywater available like when a home or small apartment building is completely plumbed for greywater use.
Like all our filter packages, the tank should be sized for your anticipated greywater surge. 4 or more people require the 110 gallon tank. A tank needs to capture greywater only long enough for it to be pumped through our sand filter and used in our high-volume irrigation emitters. This avoids overflow to the sewer or the need for large tanks, which allow greywater to become septic. See ReWater’s Owner’s Manual for details.
Will it be inspected by the City of Los Angeles or Los Angeles County? If yes, click here because you will need a 2-pump system, which requires a relay junction box, a second pump and second tank to hold the supplemental and sand filter cleaning water, and a water leveler for that second tank.
Do you plan to integrate rain harvesting into your greywater system? If yes, click here because you will need a 2-pump relay junction box, a second pump, a very large underground tank to hold the rain, and a water leveler that provides supplemental water when the tank runs dry. The option shown includes a 20,000 gallon tank but countless other sizes are available. Smaller tanks cost less but cost more per-gallon.
Tank
You must choose one. The correct tank is the one that will temporarily capture the maximum greywater “surge” when all your connected greywater fixtures are in use without overflowing to the sewer while the pump sends water out to irrigation.
