MAWSS reports Sanitary Sewer Overflow caused by grease blockage

MOBILE, Ala. — Mobile Area Water & Sewer System (MAWSS) responded to a Sanitary Sewer Overflow on September 14 from a private cleanout at 2496 Sayner Avenue as a result of heavy grease blockage on the main line.

Approximately 120 gallons overflowed, of which 20 gallons overflowed into Bolton Branch. MAWSS crews have unstopped the main line. 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.

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 Bolton Branch 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.
