Quick Answer
Maximize water efficiency with grey water by implementing a closed-loop system that collects and treats wastewater from sinks, showers, and washing machines, then reusing it for irrigation and flushing toilets.
Collecting and Treating Grey Water
Use a grey water collection system with a first flush device to divert the first flow of wastewater from sinks, showers, and washing machines, which typically contains high levels of debris and contaminants. This minimizes sediment and particulate matter entering the treatment system. A typical first flush device can capture up to 10 gallons of initial flow before allowing treated water to enter the storage tank.
Reusing Grey Water
Use the treated grey water for irrigation and flushing toilets to reduce potable water consumption. A general rule of thumb is to dedicate 10% to 20% of your irrigation system to grey water. For toilet flushing, use a grey water system with a dedicated pump and piping to supply treated water to the toilet tank, potentially saving up to 50% of potable water consumption.
