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 Dog River, 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 our sewer lines, which limits the sewer system’s capacity to move wastewater flows to our treatment plants, MAWSS diverts wastewater to our 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 (both tanks are full) – 20,000,000 gallons,
Eslava SWAT (tank is full) – 8,000,000 gallons,
Halls Mill SWAT – 5,378,700 gallons.
