Navajo Residents Push Back on Proposed Triple-Digit Wastewater Rate Hikes

A household in Chinle that currently pays about $28.70 a month to the Navajo Tribal Utility Authority for combined water and wastewater service could see that bill climb to $64.63 by 2029, a jump of nearly $36 a month, if the utility board approves the rate plan it has been presenting across the Navajo Nation this spring.

The proposed increases, drawn from an independent rate study conducted by consulting firm NewGen Strategies and Solutions, would raise residential water rates between 53% and 57% and wastewater rates between 219% and 243% over a three-year phase-in. Customers currently pay $16.21 per month for water and $12.49 for wastewater. Under the steeper of the two scenarios under consideration, water charges would rise to $24.82 per month and wastewater to $39.81 by the third year. The per-unit wastewater cost would climb from $1.75 to as much as $6 per 1,000 gallons, while water would go from $4.59 to $7.22. NTUA rates have not changed since January 1, 2020.

The numbers drew sharp community resistance when NTUA Customer Service Supervisor Shelly Biakaiddy led a public presentation at the Crownpoint Chapter House on March 31. Biakaiddy told attendees the proposed rates were about keeping the system running, not generating profit. NTUA Deputy General Manager Rex Kontz has argued that the utility faces the same inflationary pressures as its own customers. "As consumers we see rising costs. As a utility, we have the same rising costs for business expenses, such as equipment, materials, labor, maintenance and replacement costs of our water distribution, water wells and water treatment systems," Kontz said.

Attendees at Crownpoint pushed back by pointing to billions in ARPA and other federal infrastructure funds already directed toward Navajo water and wastewater improvements. The question they raised cuts to the heart of a governance debate: who absorbs the cost of system sustainability, ratepayers operating on fixed incomes and single-parent budgets, or tribal and federal funding streams that have recently poured money into the same infrastructure? In Apache County, where 25.1% of families live below the poverty line, the difference between a $29 monthly utility bill and a $65 one is not theoretical. Elders on Social Security and multi-generational households with limited cash flow have the least room to absorb such a step change in a basic service.

NTUA has framed the increases as unavoidable operational math across its 92 water systems, which span roughly 27,000 square miles of the Navajo Nation. Aging treatment equipment, rising contractor costs, and ongoing pipe rehabilitation needs have widened the gap between what the utility collects and what it spends to keep water flowing. The Chinle NTUA District Office held one of the early public sessions on March 17. Kayenta was on the schedule for April 7, with the Dilkon district following April 14.

The final public hearing is set for May 21 at the Navajo Nation Museum in Window Rock. If the board approves a new tariff, rates would take effect in September 2026 and appear on October utility bills. Apache County residents who want to submit comment before the vote can reach NTUA at P.O. Box 170, Fort Defiance, AZ 86504 or by phone at 1-800-528-5011. Chapter leaders in Chinle and neighboring communities should coordinate testimony ahead of the Window Rock hearing, where the board's decision will be made.
