The Kansas Department of Health and Environment issued a boil water advisory for a portion of Sedgwick County’s Rural Water District #4, effective Sept. 9, 2026, affecting areas generally south of Kellogg Avenue (Highway 54) from Maize Road to 295th Street — boil water advisory wichita ks residents should follow precautions until testing clears the system.
KDHE said the advisory followed a water main break that caused a loss of pressure in the distribution system and could allow bacterial contamination when chlorine residuals fall, and it will remain in effect “until the conditions that placed the system at risk of bacterial contamination are resolved,” according to local reporting and the KDHE notice cited by regional outlets.
Officials told residents to boil tap water for at least one minute before drinking or using it for food preparation, dispose of ice and not use automatic icemaker ice, and to disinfect dishes by immersion in boiled or properly chlorinated water, per the KDHE guidance reproduced in local reports.
If tap water appears cloudy, KDHE advised flushing lines until water runs clear. The advisory notice also said water used for bathing generally does not need boiling but that children should be supervised to avoid swallowing water and people with open wounds should consult a physician, as reported by KWCH and other local outlets.
The City of Wichita has been posting updates about water operations while bringing a new water treatment plant into city operation; a Wichita City media advisory said the city signed a certificate of occupancy for the new facility and will begin a training period before fully bringing the plant online in 2027.
Only KDHE can rescind the advisory after required testing at a certified laboratory, local coverage noted, so residents should watch official KDHE and city channels for a rescind notice and test results that confirm the system is safe.
Practical steps for residents: use bottled water or boiled water for drinking and cooking; throw out ice made before the advisory; run faucets until they clear if water looks discolored; and follow any further instructions from KDHE or your local water supplier.
