St. George reports wastewater expansion, new wells and reservoir design as water priorities
Summary
City leaders said a two‑phase wastewater expansion increased capacity to 25.4 million gallons per day, described new tank and well projects, and reported a designed reservoir awaiting Army Corps permitting.
Mayor Michelle Randall and city staff detailed recent and planned water projects as top priorities for a desert city that expects ongoing growth.
The city completed the second phase of the St. George Regional Wastewater Reclamation Facility in 2024, increasing treatment capacity from 17,000,000 gallons per day to 25,400,000 gallons per day, the mayor said. The reuse water from the facility meets the requirements for Type 1 reuse and the city has used reuse water on golf courses, cemeteries, schools and some residential areas for nearly 20 years.
Other projects cited included the Hidden Valley irrigation tank replacement — replacing a 130,000‑gallon steel tank with a 1,000,000‑gallon concrete tank — and the Homestead Well drilled on city land within the Red Cliffs Desert Reserve to provide redundancy for the City Creek, Mill Creek and Ledges groundwater wells. City officials said the Graveyard Wash Reservoir has been designed to store treated water from the wastewater plant but is awaiting final permitting from the U.S. Army Corps of Engineers.
The mayor also said Tonaquint Cemetery is undergoing an expansion that will add roughly 2,500 burial plots and space for 1,000 columbarium niches; construction could be finished "as soon as March," she said.
Why it matters: St. George leaders framed these projects as necessary to support growth and ensure redundancy in the city’s water supply and reuse systems, and to conserve potable water by expanding reuse and replacing turf with artificial surfaces in park conversions.
Supporting details: the address referenced long‑range planning — including a 20‑year water plan available on the city's website — and positioned the projects within conservation and reuse efforts. The mayor and the Water Services Director emphasized reuse water meeting Type 1 reuse standards and specific capacity increases at the wastewater plant.
Ending: City officials said further details, schedules and permitting updates are available via city project pages and the water department’s published plans.
