Frequently Asked Questions
Greywater systems reduce your water bill and lower your environmental impact by reusing water from showers, sinks, and laundry. This reduces the demand on municipal water supplies, conserves water during droughts, and can even reduce the strain on your septic system. It also lessens the energy needed for water treatment and distribution.
Greywater typically includes water from showers, bathtubs, bathroom sinks, and washing machines. Water from toilets (blackwater), kitchen sinks (due to food waste), and potentially contaminated sources is generally excluded. The specific regulations in Los Angeles dictate which sources are permissible for greywater recycling systems.
Greywater is collected from approved sources, filtered to remove solids and contaminants, and then disinfected. This treated water is then stored and used for subsurface irrigation, toilet flushing, or other non-potable purposes. The system must be designed to prevent cross-contamination with the potable water supply and meet local regulations.
