In a proactive move driven by sensitivities around excessive water usage, Tucson’s City Council unanimously approved a new ordinance mandating stricter oversight for large water customers. This initiative comes in response to controversy over “Project Blue,” a proposed data center that could have consumed hundreds of millions of gallons annually without full public disclosure.
What utilities need to know:
-
Threshold & Applications: Any entity requesting more than 7.4 million gallons per month must submit a detailed water conservation plan to the Tucson Water Director, who will then forward it to the City Council for approval.
-
Transparency & Oversight: Applications and associated conservation plans become public records—an important step for transparency in industrial permitting. Compliance plans must also be updated every five years.
-
Penalties for Noncompliance: The ordinance introduces tiered penalties for usage violations, ranging from 200% to 2,000% of monthly charges, escalating with recurrence and duration. Persistent offenders may face water restriction or disconnection.
-
No Fees, For Now: At this stage, the city will not impose application fees or adjust water rates for large users.
The ordinance directly addresses fears around data center development, long considered high-demand, low‑transparency water users. (Project Blue’s former annexation planning was shelved amid public outcry.) Pima County and neighboring Marana have already moved to improve regulatory guardrails on industrial water users. Tucson’s new ordinance creates a coordinated front against unregulated, high-volume water demands.
This regulation complements Tucson’s long-established water reclamation and conservation initiatives, including reuse systems and groundwater preservation efforts.
Bottom line? Tucson’s policy sets a precedent for other utilities and municipalities navigating growth in water-intensive industries. By demanding transparency, conservation planning, and enforceable penalties—all without revenue-generating fees—it balances economic development with resource stewardship. In rapidly growing or drought-sensitive regions, similar frameworks could become essential for sustainable utility operations.
