Graywater rebates in California
9 programs in California pay residents for graywater. 8 list themselves as open now, and the median maximum is $125 per household. 11% ask for a plan, sketch or plant list before they approve a project.
A few water utilities rebate laundry-to-landscape graywater systems that send washing-machine water to the garden, usually after a workshop and a permit or code check.
