Kennesaw is served by Cobb County Water System, which owns and maintains the line from the main to the meter. The pipe from the meter to the house belongs to the property owner, and the city's Building Services handles the permit. Call the number on this page to be connected with a local plumber in Kennesaw.
Kennesaw doesn't run a water department; Cobb County Water System serves the city with water from the Cobb County-Marietta Water Authority. Most homes here are from the 1990s and 2000s, with a median build year of 1998 and about 11% built before 1980, so the line in your yard is usually plastic or copper that fails at a joint or a disturbed section rather than from old age.
Many Kennesaw neighborhoods sit on sloping ground near Kennesaw Mountain and along Cobb Parkway, so a leak on a hillside lot may surface well downhill from the actual break. Water follows the pipe trench and the clay layers beneath it, which is why the plumber traces the line from the meter rather than simply digging where the puddle is.
Do this now
- Shut the main valve at the house if water is coming up fast or the house has little pressure.
- Look in the meter box. If it's flooded, that's Cobb's side; call 770-419-6201 for broken water lines.
- Verify the leak. With nothing running, watch the meter's leak indicator.
- Mark and photograph the wet area and any sinking soil.
- Think back. Recent fence, pool, sprinkler or landscaping work along the route is a common cause and worth mentioning.
