In a push for citizens to install greywater irrigation systems in their homes, the SFPUC (city water department) has launched a program to offset the cost of materials for qualifying households. The so-called Laundry-to-Landscape program requires a formal application with proof that the property has a working washing machine and a yard that is level or downsloping away from the machine's outflow. The first 150 qualifying households will receive a 95% subsidy toward the purchase of a hardware kit (hub connectors, three-way valves, etc.) to divert greywater from the sewers and use it to irrigate the garden.
Only 1- or 2-unit residential buildings are eligible, and only these buildings are allowed to install greywater systems without a permit from the building department. To encourage and promote the use of graywater systems in larger and/or commercial or industrial buildings, the SFPUC also offers a rebate up to $225 toward the cost of obtaining a permit. To be eligible, the graywater system must be used for subsurface irrigation only.
