MAWSS updates Sanitary Sewer Overflow report

MOBILE, Ala. — Mobile Area Water & Sewer System (MAWSS) responded to multiple Sanitary Sewer Overflows in the Mobile area between June 21-23. These sewer overflows occurred because heavy rainfall infiltrated the sewer lines. MAWSS said it is addressing overflows with capital projects.

Ongoing rainfall is causing the overflows to be intermittent. MAWSS is aware of the issue and will continue to monitor the overflows until all rainfall clears the area over the next several days.

Below are the documented locations, accumulated totals and receiving waters of both updated and new overflows as of Friday morning:

Location                                                  Estimated Gallons                        Receiving Water

120 Demouy Ave. @ Murray St.             29,625                                            Eslava Creek

766 Johnston Ave.                                   107,200                                          Eslava Creek

101 Mohawk St. @ Elizabeth St.             5,700                                              Eslava Creek

50 Westwood St. @ Homewood St.        21,425                                            Eslava Creek

8381 Airport Blvd.                                  Evidence Only                               Miller Creek

Dr. Bernard H. Eichold II, Health Officer for the Mobile County Health Department, advises area residents to take precautions when encountering any standing water that may have accumulated because of these overflows. 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 Eslava Creek, Three Mile Creek, Miller Creek and Mobile River for recreational purposes because of these overflows. All seafood harvested in this general area should be thoroughly cooked before eating. People should wash hands after cleaning seafood and before preparing food.

* In order to reduce the impact of heavy rains infiltrating its sewer lines, which limits the sewer system’s capacity to move sewer flows to our treatment plants, MAWSS diverts sewer to large temporary storage facilities. This reduces SSO volumes and aids in maintaining conveyance capacity in the system. Below are Severe Weather Attenuation Tanks (SWAT) and volumes of sewer diverted to each that has been kept from discharging into land or water as of Tuesday:

Three Mile SWAT — 4,948,519 gallons

Eslava SWAT — 5,333,328 gallons

Halls Mill SWAT — 3,012,100 gallons
