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 August 3 at 3659 Cottage Hill Road. Approximately 1,050 gallons of wastewater overflowed because of grease blockage.

The wastewater was contained and did not reach state waters. MAWSS crews have cleared the blockage and are taking steps to prevent further 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

Dr. Kevin Philip 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.
