13 Effective Plant Based Grey Water Systems
1. Young Reed Beds
The most common way to mimic a wetland is to construct a series of reed beds. The reeds grow well in fine gravel or sand. The gravel catches large waste particles in the grey water.
It is best to build the beds on a slope below your house so water can flow naturally through the system. These reed beds are young. As they grow they will be able to handle more volume. After the two reed beds is a bed of cattails, planted in a finer silt, which will remove the last of the residues from the water.
