Filter Systems

ReWater’s filter systems recycle your water immediately.

The water is filtered and used immediately according to the irrigation programs set on our controller. This process keeps greywater, which has a lot of organics, from turning septic. Immediate use also saves you from buying a large tank that needs costly UV and/or ozone and constant cleaning.

Our systems can filter grey, rain, or both.

If you don’t produce enough greywater to satisfy your irrigation demand that day by midnight, our controllers automatically supplement any balance with city water.

With the rain option, the controller will use greywater first, then rain, then if it still needs water to finish the programs, it uses city water:

Grey and Rain systems for apartments and homes:

NOTE: The code requires both the filter unit and the drip irrigation to be approved by the manufacturer for untreated greywater. Anything less will clog up over time. All our greywater filter systems use ReWater’s proprietary underground drip emitters to form a complete ReWater® system. Rain can be used in conventional drip emitters.

Our systems have a Self-Cleaning Filter

Our controller causes the sand filter to be backwashed based on accumulated irrigation run-time. On a signal, debris captured in the sand is automatically removed by backwashing the sand. That debris goes to the sewer. When the sand is clean, the controller resets everything for the next day’s irrigation schedule.

Systems within Los Angeles County or the City of Los Angeles must store the city water in a second tank, where a pump will send the stored water through the sand filter for cleaning. That second tank is often a large rain tank that is satisfying Low Impact Development (LID) requirements.

Those large rain tanks are themselves backed up with city water so your landscape always receives the required irrigation.
