While simple RWH to irrigation systems may be legal without a permit, more complex systems that connect with indoor or outdoor plumbing, or for larger venues will likely require building permits. County planning, public health and environmental health agencies, city plumbing, building and public works departments could all potentially have some authority over your system.
The good news is that agencies are increasingly favorable toward RWH, because it helps relieve stress from stormwater runoff. Some cities and water utilities offer rain barrels, rebates, incentives and programs that greatly encourage the practice of RWH. If such incentives do not yet exist in your area, write to your city’s Department of Public Works and to your water provider to request rebates for RWH systems.
Please see Wholly H2o's Policy and Legislation information, as well as Rebates, Incentives, Programs, to find out what is available in your specific California location.
