Water Quality at Home

Water pouring into glass

Cobb County Water System delivers you water from Lake Allatoona and the Chattahoochee River after it has been thoroughly treated and tested. Once this treated drinking water reaches your water meter, the plumbing, pipes, water heater, optional filtration systems, and fixtures are your responsibility to maintain and repair. Maintaining clean and efficient plumbing components at home ensures the water quality won’t be diminished once it enters your property.

We all play a key role in keeping Lake Allatoona and the Chattahoochee River sources of safe drinking water. Learn how you can minimize and reduce your impact on these watersheds on the pages of this website.
