Full Breakdown
Under California Water Code §10573 (added by AB 1750, the Rainwater Capture Act of 2012), property owners may capture rainwater from rooftops for nonpotable use without a water-rights permit from the State Water Resources Control Board. El Monte Municipal Code Chapter 13.16 (Stormwater Management and Discharge Control) and the city's LID ordinance (adopted to comply with the Los Angeles MS4 permit issued by the Los Angeles Regional Water Quality Control Board) require new and redevelopment projects to use onsite stormwater capture including rainfall harvest and reuse, biofiltration and infiltration. Larger cisterns (over 5,000 gallons) may require a plumbing permit per the California Plumbing Code Chapter 17 (rainwater catchment systems).
Violations & Fines
No fines for residential rain-barrel installation. Unpermitted larger cisterns or systems that discharge captured water into the city storm drain without LID compliance can be cited under Chapter 13.16 (stormwater violations: typically $100–$1,000 per day per the MS4 permit).
