Residents of Thornbrook and Steeplechase subdivisions under extended boil advisory

originally posted on June 18, 2016


The city’s Water and Light Department is extending a precautionary boil advisory for the Thornbrook and Steeplechase subdivisions through Monday because water pressure has dropped too low again.

More than 600 residents in the area have been under the advisory since Monday because data shows that beginning around 4 a.m. water pressure drops substantially — likely because of irrigation system demand. A news release from the Water and Light Department said no problems have been found in the city’s water distribution system and it appears the problem is caused by private sprinkler systems operating at the same time.

The department has asked residents in the Bradbury Estates, Creek’s Edge, Thornbrook, Steeplechase and Wyndham Ridge subdivisions to change the time of their irrigation system use to curb the problem. The suggested irrigation schedule is as follows:

  • Midnight to 1 a.m.:
  • Abbington Court, Astoria Court, Garden Brook Court, Greenberry Court, Hazeltine Court, Largo Drive, Leatherbrook Drive, Morning Star Court, Nearpoint Court, Prairie Creek Drive, Sedgewick Drive, Shackelford Court, Summer Brook Court, Thornbrook Ridge and Thornbrook Terrace.
  • 1 to 2 a.m.:
  • Abbington Terrace, Bridlewood Court, Center Brook Court, Cody Court, Fall Brook Drive, Heatherstone Court, Mist Grove Court, Newbury Way, Sawgrass Drive, Shearwater Court, Silver Cliff Drive, Steinbrooke Terrace and Stonington Drive.
  • 2 to 3 a.m.:
  • Beacon Falls Drive, Canyata Court, Chamois Drive, Claybrook Court, Cochero Court, Henwich Drive, Julesburg Way, Sattinwood Court, Sibley Court, Steeplechase Drive, Villa Wood Court and Winding Woods Court.
  • 3 to 4 a.m.:
  • Abercorn Drive, Annandale Court, Autumn Ridge Court, Brookthorn Court, Coral Ridge Court, Dunmeyer Court, Garden Grove Drive, Laredo Trail, Majestic Circle, Regal Way, Saddle Ridge Drive, Salton Court and Shadow Circle.
  • 4 to 5 a.m.:
  • Astoria Way, Bell Flower Court, Canter Court, Shearwater Drive, Spicewood Drive, Steeplechase Court, Thornbrook Parkway, Valhalla Court and Winterbrook Court.

If there is not a change in demand in the early morning hours with this voluntary request, an alternating day schedule for irrigation with specific times likely will be required, the release said.

The Missouri Department of Natural Resources mandates boil advisories when water pressure drops below 20 pounds per square inch because the low pressure can allow water to flow backward — allowing contaminants into the distribution system. Recent water samples in the area have not found any contaminants, according to the release.
