Summary
Murrieta declares wasteful landscape irrigation a public nuisance under Development Code Section 16.28.100. Overspray, low-head drainage or runoff that sends irrigation water onto sidewalks, streets, parking lots or a neighbor's property is unlawful, and the city coordinates with local water purveyors to enforce it through tiered rates and penalties.
It is hereby declared that the willful and knowing waste of water from inefficient landscape irrigation shall be a public nuisance. It shall be unlawful for any firm, corporation, person, or persons to knowingly allow water waste resulting from inefficient landscape irrigation runoff leaving the target landscape due to low head drainage, overspray, or other similar conditions in which water flows onto adjacent property, non-irrigated areas, walks, roadways, parking lots, or structures.

Full Breakdown
100 of the Landscaping Standards and Water Efficient Landscaping chapter targets water lost to inefficient irrigation rather than setting fixed watering days. It is unlawful for any person to knowingly allow water waste from inefficient landscape irrigation, specifically runoff caused by low head drainage, overspray, or similar conditions that carry water onto adjacent property, non-irrigated ground, walkways, roadways, parking lots or structures. The restriction can be relaxed only in two situations: where the landscape sits next to permeable surfacing that absorbs the runoff, or where adjacent non-permeable surfaces are built to drain entirely back into landscaping.
Rather than fielding every complaint itself, the city relies on local water purveyors to enforce efficiency for existing yards, while the city coordinates conservation programs that can include tiered water-rate structures, allocation-based conservation pricing, irrigation audits or surveys, and direct penalties for water waste. 130 (500 square feet new, 2,500 square feet rehabilitated) must also meet MWELO design standards, and larger developments are subject to irrigation audits at a rate of roughly one in seven lots. 28 violations through the development code's general enforcement chapter.
Violations & Fines
Violating the water-waste prohibition is enforceable by the city under Development Code Chapter 16.84 (Enforcement Provisions), and the city's coordinated purveyor programs can layer on tiered or allocation-based rate penalties, irrigation audits, or surveys for households that continue wasting water after being flagged.
