Folsom FAQ
Do I need a permit for a rain barrel in Folsom?
No. Residential rain barrels and cisterns up to 5,000 gallons for outdoor landscape irrigation are permit-exempt under California law. Just make sure inlets are screened to prevent mosquito breeding.
Can I use harvested rainwater during drought restrictions?
Yes. Harvested rainwater is not subject to municipal water use restrictions — it's your own supply. However, you still cannot allow runoff onto hard surfaces.
Galt FAQ
How big a rain barrel can I install without a permit?
Galt generally follows state guidance that connected barrels under roughly 100 gallons and not integrated with the potable plumbing do not require a permit.
Can I hook rainwater into my toilet tank?
Only with a plumbing permit, approved filtration, and a proper air gap or listed backflow device to prevent cross-connection with City water.
