Guymon advances Mesa Water Project to secure long-term drinking water supply

When Well No. 21 failed in July 2025, Guymon lost 827 gallons a minute, about one-quarter of the city’s daily water supply, and water restrictions followed. That shutdown put a hard number on the question now driving the Mesa Water Project: whether Texas County’s largest city can build enough new capacity before the Ogallala aquifer and its older wells run even thinner.

Mesa is designed as a new municipal lifeline, not a cosmetic upgrade. The project centers on a new well field in the Mesa area east and southeast of Guymon, collector pipelines, and transmission capacity to move potable water into the city system. OWRB’s award materials say the work includes deeper aquifers, automated monitoring, high-efficiency pumps, and a 17-mile transmission line. City materials also point to direct potable reuse as a backup long-term option, and the water department says the Mesa well system is intended to provide drinking water for decades even as the local wells continue to depend on a declining Ogallala aquifer.

The financing shows how expensive that security is. On Feb. 20, 2024, the Oklahoma Water Resources Board approved a $675,150 grant paired with $870,950 in local funds to drill seven test wells and identify permanent sites. On May 21, 2024, the board approved a separate $10 million Financial Assistance Program loan to help pay for planning and design of an additional water source, supply-system improvements and rehabilitation of a leaking lagoon. OWRB said the 30-year loan structure would save Guymon customers an estimated $2,359,700 compared with traditional financing. Mayor Kim Peterson and Interim City Manager Michael Shannon backed the package as the city built out the project in phases.

By late 2024 and 2025, those phases had moved from concept to engineering detail. Guymon’s records show a Dec. 10, 2024 council presentation on direct potable reuse options, and a 2025 update said Phases 2 and 3 were formally presented and approved at a special called council meeting. An Oct. 22, 2025 public update from Ardurra described phase 3 with an 18-inch raw-water transmission line, two 850,000-gallon storage tanks and a packaged booster pump station, with phase 3 construction estimated at $21.5 million. Later reporting put the full Mesa project at $32.2 million and noted timing uncertainty after a $17.5 million Department of Energy grant was paused.

The city’s biggest argument for Mesa is not growth alone, but survival. OWRB recognized Guymon with a Water for 2060 Excellence Award on Dec. 4, 2025 for a project aimed at protecting agricultural, industrial and residential users for years to come. For households and employers, the payoff is supposed to be fewer emergency restrictions and less risk when a key well fails, but the cost of that reliability is still being paid through a long, staged build that will shape Guymon’s water bills and growth limits for years.
