Water Rates & Fees

Water & Sewer Rates

Cobb Water System customers are billed monthly for water and sewer usage. The water meter is read monthly to determine the consumption.

For more detailed information on the current rates and fees, please click here.

Up to a maximum of 10% of the Water System's revenue may be transferred to the County's General Fund. For further information, please visit the What is the County’s policy regarding water fund transfers? | Cobb County Georgia webpage to learn more.

A comparison of Cobb's current rates compared to other water utilities in the metro Atlanta area is provided below.

Note: The Cobb rates shown are our Unincorporated Rates, which include funding for stormwater services.  The City of Atlanta’s rates are the only other rates depicted that also fund stormwater services.
