California Has the Highest Commercial Water Rates in the Nation — and They're Still Rising
Cal Water received approval for an 11.1% rate increase for 2026. California American Water filed for a 30.3% cumulative hike by 2029. Assembly Bill 1572 restricts potable water for commercial irrigation. The AWS reports average savings just above 22% across its North American projects. Individual results vary — subject to written performance agreement.
The California Water Situation
California Water Rates Are Among the Highest in the US — and Rising Fast
California faces a structural water crisis driven by persistent multi-year drought and chronic overuse. Commercial properties are bearing the cost through mandatory rate hikes, tiered penalty pricing, and conservation mandates.
Commercial properties in California may have site-specific water-system and billing considerations. Smart Valve™ assessment and installation planning is based on the property's actual setup, billing history, and local requirements. Published project results vary by site and measurement period.

Cal Water +11.1% in 2026
Cal Water received regulatory approval for an 11.1% rate increase effective 2026. This is not a projection — it's confirmed. Commercial customers in the Cal Water service area will pay more starting this year.
California American Water +30.3% by 2029
California American Water filed for a 30.3% cumulative rate hike by 2029. For commercial properties already spending $10,000+/month on water, this translates to $3,000+ in additional annual costs before any usage changes.
AB 1572 — Commercial Irrigation Ban
Assembly Bill 1572 prohibits potable water for irrigating nonfunctional turf at commercial properties starting January 1, 2027. Violations carry significant fines. Smart Valve™ reduces your total metered consumption before enforcement begins.
State Water Board Conservation Targets
The State Water Board maintains ongoing mandatory conservation targets for commercial properties. Non-compliance risks service restrictions and fines. Smart Valve™ delivers guaranteed measurable reductions that satisfy regulatory reporting.
Tiered Rates Penalize High Usage
California utilities use aggressive tiered rate structures. High-usage commercial properties pay premium rates per gallon. Smart Valve™ drops you into lower tiers immediately, reducing your per-gallon rate across your entire bill.
