ST. GEORGE — A 12-inch water line that ruptured near the Green Valley Spa in St. George is affecting hundreds of homes and businesses and officials are asking residents to stop watering outdoors.
The break happened about 2:30 p.m. Friday and triggered the temporary closure of Canyon View Drive and south Village Road. The water line serves residents and businesses in the Green Valley and Sunbrook area, Marc Mortensen, assistant to the City Manager of St. George, said.
Residents will be affected in different ways.
“Some will experience low pressure, some will have no water until later this evening,” Mortensen said.
The city is rerouting water to as many customers as possible. The water line will be repaired tonight but residents are being asked to turn off their outdoor watering systems until 8 p.m. Saturday night.
“We don’t mind if people use their showers or their faucets indoors, but the outdoor irrigation is a concern because that’s, you know, 60 percent of all the water used is used on outdoor irrigation,” he said, adding if everyone waters outdoors tonight or tomorrow the affected water tank won’t have a chance to recover.
“So we’re asking everyone to just turn off their outdoor water systems until tomorrow night,” Mortensen said.
“It’s going to take some time for that tank to restore, once we get the line repaired,” he said. “It’s going to take at least eight to 10 hours to start to fill back up. We’d prefer that no one water in that area until tomorrow night.”
The ruptured line is the main line that fills a city water tank in the Green Valley Gap and provides culinary water to the area. The tank is fed from a variety of sources including wells and reservoir water.
“So you can imagine, the tank is several hundred feet above the area that had the break, so there’s a lot of pressure on that line,” Mortensen said. “Crews immediately shut off the tank and we did lose a lot of water. Water levels at the tank dropped significantly because of the break, and it’s done a fair amount of damage to Canyon View Drive.”
The water line that burst is about 20 years old, Mortensen said. Water lines can last up to 70 years, depending on soil conditions including pressure, soil type, soil movement and other factors.
“We have really corrosive soils in St. George,” he said.
The Sunbrook Golf Club is not affected by the break or by the restrictions because it is not part of the culinary system, Mortensen said. Rather, it is on a secondary “gray” water system fed from a water treatment plant in Bloomington.
