Riverside County
Menifee Municipal Code Ch. 15.04 (Landscape Water Use Efficiency) explicitly encourages onsite stormwater capture and graywater reuse for landscape irrigation. Graywater installations must comply with the California Plumbing Code (CPC Chapter 16A). State law — the Rainwater Capture Act of 2012 (AB 1750, Cal. Water Code §10574) — permits rooftop rainwater harvesting without a water-rights permit. EMWD offers graywater 3-way diverter-valve rebates (up to $50) for laundry-to-landscape systems serving Menifee customers. The City requires a building permit only when rainwater storage tanks exceed thresholds in the California Plumbing/Building Code (typically tanks ≥5,000 gallons or pressurized systems tied to potable supply).

Mead Valley FAQ
Do I need a permit for a rain barrel in unincorporated Riverside County?
No state water-right permit is needed under the Rainwater Capture Act of 2012 for rooftop collection used outdoors for non-potable purposes. Simple barrels and small cisterns generally need no county permit; large, plumbed, or potable systems may require building/plumbing approval.
Can I use harvested rainwater for my lawn?
Yes. Using rooftop-captured rainwater for landscape irrigation is exactly the non-potable outdoor use the state law authorizes, and it helps you avoid potable-water restrictions and runoff prohibitions.
Menifee FAQ
Do I need a City permit to install rain barrels?
No permit is needed for typical residential rain barrels (≤5,000 gal aggregate, non-potable, screened). Larger cisterns or tanks tied into structures may require building-permit review.
Can I divert my washing machine to the landscape without a permit?
Yes — a single-fixture, gravity-fed Laundry-to-Landscape system is exempt under California Plumbing Code §1503.1.1. Don't pressurize or connect to potable lines.
Are there rebates?
EMWD offers a rebate (up to $50) for the 3-way diverter valve component of a qualifying L2L system. Check current rebate availability on emwd.org.
