COLUMBIA — The city's plans to remove four water service lines Tuesday on Walnut Street might cause water service disruptions for Columbia Water & Light customers in the immediate area.
Walnut Street will be closed to traffic from College Avenue to Orr Street starting at 6 a.m., according to a news release from the department.
Columbia Water & Light uses water service lines,which draw water from the main line, that run to each individual customer. The section of main line under construction must be drained while crews work to remove the service lines. The service lines go to buildings that will be demolished.
While the main line is closed, customers in that section will experience a temporary water outage. Connie Kacprowicz, utility services specialist, said the outage would ideally affect only two customers. If the valves in the section of the main water line are not working correctly for some reason, the disruptions could affect up to 10 customers.
If the water pressure in the main line drops below 20 pounds per square inch, there is a possibility for backflow from the individual service lines. A precautionary boil advisory, after the project could be in effect for a day for the affected customers.
The Missouri Department of Natural Resources requires a test to verify the safety of the water after a drop in pressure and would take about 24 hours to complete. Residents affected by the boil advisory will be notified by crews or by a hangtag left on the door, Kacprowicz said.
After the project is finished, the empty section of the main water line will be flushed before being used again. Slight discoloration to water could result from the stirring of natural sediment left in the pipe. Residents in the area experiencing the discoloration should let the water run for a few minutes until it is clear again, Kacprowicz said.
Crews should finish the project by Tuesday afternoon, she said.
