"Laundry to Landscape" Greywater Systems


LaundrytolandscapeCalifornia’s new greywater code allows single and two- family dwellings to install greywater systems from the washing machine without a permit so long as 12 conditions are met, including use of a diverter valve that can direct the greywater back to the sewer or septic when diapers are washed. A clear label for the valve and an operation/maintenance manual that stays with the house are also required. The greywater may be distributed in “mulch basins” so long as the outlet is covered by 2” of soil, rock, sand, mulch, or a solid shield. Read more about them here.
