Waste Water System
MAWSS' wastewater system serves approximately 205 square miles in Mobile County and approximately one square mile in Baldwin County. The collection and transmission system consists of approximately 1,260 miles of gravity sewers, approximately 196 lift stations, and approximately 140 miles of force mains. MAWSS currently owns and operates two conventional wastewater treatment facilities and five decentralized wastewater facilities.

MAWSS uses a Capacity Assurance Program to monitor the available capacity of their wastewater collection and transmission systems. Each request for wastewater service is evaluated to determine if capacity is available to accommodate the additional flows from the customer. Download a Wastewater Capacity Review Application here.

Biosolids are nutrient-rich organic material resulting from the treatment of domestic sewage in a treatment plant. When treated and processed, these residuals can be recycled and applies as fertilizer to improve and maintina productive soils and stimulate plant growth. Biosolids processed at MAWSS' C.C. Williams WWTP are provided to local farmers, who agree to follow EPA guidelines when distributing biosolids onto their land.
