The Authority delivers purified finished water to its 10 wholesale customers through a 200 plus mile transmission system of iron and concrete underground pipes. The system includes water transmission pipes ranging in sizes from 16 to 64 inches with nearly half of the pipe at 36 inches. This water transmission network is fed from both of the CCMWA water treatment plants for maximum flexibility and reliability.

CCMWA water treatment professionals are working 24 hours a day, seven days a week to monitor system pressures, tank levels and water quality. The transmission system, which includes connections to its out-of-county customers, lies entirely within Cobb County with water storage facilities located throughout the County for demand equalization, fire protection and emergency conditions.
