Precautionary boil advisory extended for southwest Columbia areas
COLUMBIA — UPDATE: on Friday, June 24, Columbia Water & Light lifted this precautionary boil advisory.
Columbia Water & Light has indefinitely extended the precautionary boil advisory for Thornbrook and Steeplechase subdivisions.
Columbia Water & Light said there continues to be a substantial drop in water pressure during the early morning hours in some southwestern Columbia subdivisions. The agency said no problems were found on the water distribution system, so it appears irrigation system demand is causing the problem.
Columbia Water & Light is urging residents to follow a voluntary irrigation schedule in the Creek's Edge, Thornbrook, Steeplechase and Wyndham Ridge subdivisions so all of the irrigation systems do not operate at the same time.
"Following the irrigation schedule shared with residents last week and again today is the fastest short term solution to lifting the precautionary boil advisory", said Ryan Williams, assistant utilities director for Columbia Water & Light.
The agency has divided residents of these areas into five groups that will be asked to set their irrigation timers between midnight and 4 a.m., saying if enough residents rotate their water irrigation schedule, the demand will decrease.
Columbia Water & Light said the boil advisory will be lifted when there is not a substantial drop in pressure. It said, if there is not a change in demand, then an alternating day schedule for irrigation with specific times will likely be required.
