MAWSS reports Sanitary Sewer Overflow caused by grease blockage

MOBILE, Ala. — Mobile Area Water & Sewer System (MAWSS) responded to a Sanitary Sewer Overflow (SSO) on July 23 from a manhole at 5725 Old Pascagoula Road. It was the result of a heavy grease blockage on the main line.

Approximately 300 gallons overflowed. Of that total, 150 gallons overflowed into Halls Mill Creek. MAWSS crews have unstopped the sewer. Steps will be taken to prevent future overflows at this location.

Grease blockages occur when foods containing fats, oil or grease are put down the drain. MAWSS provides free containers for grease recycling. You can learn more about the program by visiting www.itseasytobeungreasy.com.

Dr. Kevin Michaels, Health Officer for Mobile County, advises area residents to take precautions when coming into contact with any standing water that may have accumulated as a result of this overflow. Those who have come into direct contact with untreated sewage are advised to wash their hands and clothing thoroughly.

Area residents should take precautions when using Halls Mill Creek for recreational purposes because of this overflow. All seafood harvested in this general area should be thoroughly cooked before eating. People should wash their hands after cleaning seafood and before preparing food.
