What Metro Water District does

Metro Water District (legal name: Metropolitan Domestic Water Improvement District) is a public water improvement district headquartered in Tucson, Arizona, that supplies metered municipal water to approximately 23,985 active residential, multi-family, and commercial connections across four service areas: Metro Main (23 square miles in northwest Tucson, 17,953 connections), Metro Hub (northeast Tucson, 1,682 connections, acquired from Hub Water Company in 1999), Metro Southwest (three separate areas in southwest Tucson totaling 2,500 connections, acquired from Thim Water Utilities in 2009), and Metro West (annexed in 2005, ~1,850 anticipated future customers). The system draws water from municipal aquifer wells and supplements supply with a Central Arizona Project allotment, with unused CAP water currently recharged to the Tucson basin aquifer as a long-term renewable reserve.

The District's underlying technology stack is a municipal pipe network fed by wellfields, reservoirs, and pumping stations, layered with dual indoor/outdoor metering, an Advanced Metering Infrastructure rollout, and a WaterSmart customer portal for account management and consumption visibility. Capital projects in FY2026 include the Northwest Recharge, Recovery, and Delivery System (NWRRDS), an $8.84M collaborative build with the Towns of Oro Valley and Marana for managed aquifer recharge and recovery, and a $5.70M AMI deployment backed by $5M in grants. The District also supports conservation rebates, a backflow prevention program, and a demonstration garden for water-wise landscaping education.

Metro Water District's revenue model is overwhelmingly usage-based and recurring: metered water sales (availability charges, consumption charges, and resource utilization fees) generate 81.92% of operating revenue, projected at $29.03M in FY2026. The remaining 18.08% comes from connection fees, development fees, plan review and permitting, backflow testing, service transfer fees, infrastructure rehabilitation fees, conservation penalties, water storage services, and interest earnings. Customer segments include residential accounts (primary, with $200 refundable deposits), commercial and multi-family accounts ($1,500 deposits, backflow testing required), and developers/contractors (mid-market use case). Total operating revenue plus other funding sources reaches $36.55M in the adopted FY2026 budget, against $13.8M of outstanding debt across three WIFA loans and Series 2020 senior revenue obligations carrying a Moody's Aa3 rating.

Broad incumbents

• Tucson Water: Tucson's municipal water utility, the dominant water provider in the same metro area as Metro Water District. Directly comparable operating model (aquifer + CAP supply, metered distribution) but serves a much larger customer base and overlaps in some service areas.
• EPCOR Water USA: Subsidiary of EPCOR Utilities serving water and wastewater customers across Arizona and the Southwest. Comparable municipal water utility model with regulated rates, AMI deployment, and water reuse initiatives in similar arid markets.
• Liberty Utilities (Arizona Water): Investor-owned water utility serving multiple Arizona communities. Comparable regulated rate-base model, AMI rollout, and customer mix, with overlapping service areas in the Sun Corridor.
• American Water Works Company: Largest US investor-owned water and wastewater utility. Comparable regulated, rate-base business model and AMI/smart metering strategy, though vastly larger scale and geographically diversified.
• SJW Group: Water utility holding company operating in California and Texas with a similar pure-play regulated water model. Comparable rate-base economics, metered recurring revenue, and AMI/conservation programs.
• California Water Service Group: Investor-owned water utility serving California, Washington, New Mexico, and Hawaii. Comparable regulated rate-base model, conservation pricing, and groundwater/drought management approach to that of Metro Water.

Direct peers
