Southwest Manhattan

Officials on Tuesday afternoon advised residents in southwest Manhattan to boil water before consumption for 24 to 48 hours after three water main breaks.

The breaks caused a drop in the water pressure system, possibly contaminating the water, but Randy DeWitt, assistant director of public works for the city, said the local government wasn't aware of any known contamination.

“The advisory is strictly procedural because we know that some areas of the water system dropped below the water pressure threshold of 20 psi," DeWitt said.

The city government sent water samples to the Kansas Department of Health and Environment (KDHE), which issued the boil water advisory at 1 p.m. Tuesday. Once scientists deem the water safe without bacteria, KDHE will pull the advisory. KDHE plans to check samples again Wednesday afternoon, officials said Wednesday morning. 

Residents outside of southwest Manhattan can continue normal water use, officials said. An estimated 4,700 people are impacted by the advisory.

City administrators said the general boundaries of the affected area are South Delaware Road (east); Stagg Hill Road at Rosencutter Road (south); EJ Frick Drive at Amherst Avenue and Tamarak Drive at Arbor Drive (west); and Wildcat Creek at Seth Child Road and Poyntz Avenue at South Delaware Road (north).

City officials weren't sure what caused the breaks at Stagg Hill and Westwood roads.
