Dr. Bernard H. Eichold II, Health Officer for Mobile County, 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, Halls Mill Creek, and Three Mile Creek 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 sewer lines, which limits the sewer system’s capacity to move wastewater flows to treatment plants, MAWSS diverts wastewater to large temporary storage facilities. The diversion of flows reduces wastewater volumes in the collection system and aids in maintaining conveyance capacity in the system. Below are Severe Weather Attenuation Tanks (SWAT) and volumes of wastewater diverted to each: Three Mile SWAT (currently diverting) – 17,029,736 gallons; Eslava SWAT – 8,000,000 gallons; Halls Mill SWAT – 3,006,150 gallons.
