Greywater System: Branched Drain

In a branched drain greywater system the greywater from the house drains through a series of branching pipes and is dispersed into the landscape into mulch basin outlets. Showers, sinks and laundry can individually drain into the landscape, or be collected together into a single branched drain system. Typically branched drain systems are installed on showers, and a laundry to landscape system is installed on the washing machine. The greywater irrigation zone must be downhill relative to the shower, sinks and laundry inside the home.
