Marana's Water Rates Answer to Two Different City Halls

Inside Marana's own boundary lines, two separate companies issue water bills. One is Marana Water, the town's utility. The other is Tucson Water, which reaches into specific pockets of Marana under agreements that predate most of the subdivisions selling today. The line between them runs through some of the town's most recognized addresses, including large sections of Dove Mountain and Continental Ranch, and it has nothing to do with the price of the house, the decade it was built, or which builder's name is still on the entry monument.

Right now, the two utilities are moving in opposite directions on price. One just finished a restructuring that quietly lowered bills for its Marana customers. The other is at the start of a five-year climb the Marana Town Council approved for itself. A buyer comparing two similarly priced homes in Marana this fall could be comparing two different five-year cost curves, and neither the listing sheet nor the HOA packet is going to say which one applies.

The Boundary Nobody Draws on a Map

Tucson Water's presence inside Marana goes back to old developer contracts, not annexation. Tucson Water classifies its own service territory using a policy framework that labels most of Marana a Non-Expansion Area, meaning the utility can only serve parcels it already reached through prior agreement, generally small tracts surrounded on three sides by land it already serves. A 2016 intergovernmental agreement between Tucson Water and Marana Water spelled out exactly which parcels fall on the Tucson Water side of that line, and Dove Mountain and Continental Ranch are the two largest examples.

Because that boundary is fixed rather than expanding, new construction across the rest of Marana, the wave of building that followed Gladden Farms selling out, is landing almost entirely on Marana Water. Tucson Water's footprint inside town limits is a legacy pocket, not a growing one.

Marana Water itself is not one uniform system either. The town's utility was established in 1997 and grew by absorbing a set of previously independent local systems, including ones known internally as North Marana, Picture Rocks, Twin Peaks, Airline/Lambert, Palo Verde, Airport, and Falstaff. Three decades of piecing together older infrastructure means there is no shortcut rule tied to a subdivision's name. The town publishes a parcel-level water service area lookup tool, and it is the only way to confirm which utility actually serves a specific address before assuming anything based on the neighborhood it sits in.

The Five-Year Number Marana Set for Itself

On November 4, 2025, the Marana Town Council voted 7-0 to move forward with a multi-year rate increase proposed by Water Director Heidi Lasham. The plan raises water rates 10.5 percent every year and reclamation, or wastewater, rates 2.5 percent every year, on a schedule running from 2026 through 2030. The town's own rate study materials put the cost per gallon at about 1.7 cents in 2026, climbing to roughly 2.2 cents by 2030. New rates took effect February 6, 2026, per the town's published rate schedule.

For a household of four using about 7,000 gallons a month, the first step alone added roughly $7, moving a typical combined water and reclamation bill from about $107 to $114. Reporting on the council's discussion put the cumulative effect at close to $10 more per month by 2030, on top of whatever the bill already is today. Marana's water department cited comparisons with neighboring utilities as part of the case for the increase, noting that Marana already carries the third-highest utility bill among surrounding municipalities.

This schedule applies only to Marana Water customers. It has no bearing on the parcels served by Tucson Water inside the same town.

The Other Bill Just Moved the Other Way

In 2025, Tucson Water finalized a restructuring that splits its customers into two tiers based on whether an address sits inside an incorporated city or town. Homeowners inside an incorporated boundary, which includes Marana even though Marana Water doesn't serve every Marana address, saw their Tucson Water bills drop by about $2 a month under the new structure. Tucson Water customers living in unincorporated Pima County, outside any city or town line entirely, saw increases of 16 to 23 percent, adding an estimated $6.41 to $8.88 a month, according to coverage of the plan.

Dove Mountain and Continental Ranch sit inside Marana's incorporated boundary, so their Tucson Water customers landed on the favorable side of that restructuring, the same year Marana Water customers elsewhere in town started climbing a five-year schedule set by an entirely different governing body. Two households in the same town, both paying a water bill, are answering to two different city halls with two different sets of priorities and two different election cycles.

Why the Address Matters More Than the Subdivision Name

A similarly priced listing in Marana can sit on either side of this line, and the two five-year trajectories aren't coordinated with each other. Marana's town council controls one. The Tucson city council, through Tucson Water, controls the other. A buyer working from the assumption that "Marana water" is a single, predictable line item is working from an assumption the two utilities don't share.

Before writing an offer, the parcel-specific answer is available through the town's own lookup tool, not through the MLS. Sellers and listing agents rarely think to specify a utility provider the way they'd specify a roof age or an HVAC brand, largely because most of the town has never had to think about it. For a buyer weighing two homes at the same price point in Marana, knowing which five-year number applies to each one is part of understanding what the monthly cost of ownership actually looks like three years from now, not just at closing.

Frequently Asked Questions

Does every home in Dove Mountain use Tucson Water? Dove Mountain sits largely within Tucson Water's contracted service territory inside Marana, but service boundaries can vary block to block within a single community. Confirm the specific parcel through Marana's lookup tool rather than assuming based on the community name alone.

Could Tucson Water ever expand further into Marana? Tucson Water's own service area policy classifies most of Marana as a Non-Expansion Area, limiting new service to parcels already under prior agreement and generally capped at under 20 acres surrounded on three sides by land it already serves. That framework caps the footprint rather than growing it.

Will Marana Water's rate increases stop after 2030? The schedule the town council adopted runs through 2030. Nothing beyond that year has been approved, so a buyer planning a longer hold should ask Marana Water directly what happens once the current five-year plan expires.
