Repairs of a 36-inch water main could be completed by tonight (Tuesday), but Public Water Supply District #2 is asking customers in western St. Charles County to continue to observe a water conservation order until testing is completed on the repairs.
The conservation order includes non-essential uses such as lawn watering, car washing, and recreational use of water. Commercial and industrial users are also being asked to conserve water use as much as possible.
According to the PWSD #2 website, some users may experience lower-than-normal water pressure. The water is safe to drink, however, and no boil orders have been issued.
PWSD #2 Manager Ron Smith told 70 West Sentinel that the 36-inch main brings a supply of water from St. Louis to western St. Charles County. A leak was discovered in the parking lot of the Verizon facility at 500 Technology Drive. “It looks like corrosion was the cause, right at a T-fitting with a 12-inch pipe,” Smith said. “It was buried about 12 feet deep.”
Smith said the repairs could be done by 8 p.m., but testing must be done on the repairs and the main must remain out of service during that time.
“The best-case scenario would be that we could send out robo calls in the morning to lift the ban,” Smith said. “But you never know what might happen.”
In addition to the area indicated by the map, PWSD #2 supplies water to customers in the cities of O’Fallon, Dardenne Prairie, Lake Saint Louis, and Wentzville.
