Leak Credit Application

Unexpected leaks can occur in plumbing systems and cause high bills. Cobb County Water System encourages the prompt and complete repair of leaks. The Water System has a Leak Credit Policy that provides a partial credit for eligible leaks once in a rolling 12-month period. The credit can be applied to no more than two affected months. The purpose of the policy is to assist customers with a partial offset of the costs associated with certain plumbing failures, not to fully compensate a customer for the costs of a leak. Customers are responsible for paying the water bill while waiting for a leak credit to be processed.

For further information, please visit our leak Credit page:

Important Note

Residential customers can apply for new service online (see above), contact our Customer Service Center, Monday through Friday, 7:30 am – 6:00 pm at 770-419-6200, or visit our Customer Service Facility at 660 South Cobb Dr. Marietta, GA 30060, Monday through Friday, 8:00 am – 5:00 pm. 

All applicable fees and deposits must be paid prior to service establishment.

 New Service connection is not available on weekends or holidays.

 New customers are required to pay a $50 refundable deposit and $25 non-refundable initial service fee. Payments over the phone can only be made by credit or debit card.

 If you have or had service with Cobb County Water System and would like to establish new service, any past due balance must be paid prior to establishing service. A $25 non-refundable initial service fee is required and a $50 refundable deposit may be required.

 If you are renting the property, a lease agreement and additional information or fees may be required.

 If there is no water service at the property currently, you must ensure all the water sources (sinks, tubs, faucets/inside and outside and toilets) are off to avoid any water running and damage to the property. If the meter indicates the water is running, the service will not be restored. If an additional trip is required to restore service, a $25-second trip fee is charged to the account.

 If the house has been winterized, someone must be home in order to have service established. (Vacant and unoccupied homes are often winterized to prevent damage due to freezing pipes in colder months. When the plumbing system is winterized its main purpose is to drain all the water from the system including the water heater. If houses are not properly de-winterized, restoring water may cause potential damage due to leaking pipes).
