Whose pipe is it in Kennesaw?
The public sewer in Kennesaw is run by Cobb County Water System. The provider answers for its main and its part of the line; the line on your side is the property owner's, and that is the part we work on. More on how the line is split: who is responsible for your sewer line.

Local rules in Kennesaw
What the city and its utilities publish about the jobs we do here, each with its source (checked in October 2026). The provider's full rules are on Cobb County.
When sewage backs up
- Cobb County Water System says it can check whether county sewer lines, including lines that cross private property in an easement, are contributing to a sewer problem at a home, and it takes those reports through its emergency dispatch (Cobb County).
- Besides its emergency dispatch line for backups in homes or streets, Cobb County Water System takes reports of sewage overflows through an online form on its contact and report-forms page (Cobb County).
Your sewer line and the public main
- Cobb County Water System's FAQ puts the public sewer lines on the county and the sewer pipes within a homeowner's property on the homeowner (Cobb County).
- Where a permanent easement has been granted to Cobb County and construction is complete, the county owns and maintains the sewer line inside that easement; the Water System suggests checking the plat or deed for an easement naming Cobb County (Cobb County).
Cleanouts (1)
- Cobb County's Development Standards require sewer service laterals built for new development to be at least 6 inches in diameter within the public right-of-way or a sewer easement and to end in a cleanout assembly, with each lateral's location permanently marked in the curb (Cobb County).
Roots and pipe defects (1)
- Cobb County Water System's camera inspections of its sewers often find broken pipes, offset joints, root intrusion and improperly installed service connections, defects it repairs to help prevent blockages and overflows (Cobb County).
Grease and what goes down the drain (2)
- Cobb County Water System blames fats, oils and grease, along with 'flushable' wipes, for most residential sewer overflows and blockages, and it asks residents to put leftover cooking oil in a sealed container for the trash (Cobb County).
- Cobb County Water System notes that part of every customer's water bill goes to system maintenance and to the cleanups and other costs of grease-related sewer overflows (Cobb County).
Permits (2)
- Kennesaw's Building Services Department accepts permit applications only online, offers a homeowner affidavit for owners pulling their own permits, and schedules inspections through its online portal, with a 7 p.m. cutoff for next-business-day inspections (kennesaw-ga.gov).
- Kennesaw's Building Services page lists the 2024 International Plumbing Code with Georgia amendments among the mandatory codes it shows as effective January 1, 2026 (kennesaw-ga.gov).
Digging in the street or right-of-way (3)
- Kennesaw's development code requires a permit from the public works director before anyone cuts, digs into or opens a public street, sidewalk or city-owned easement, and the request must include a plan showing depth, open-cut or boring method, and restoration (Municode).
- Kennesaw expects major street crossings to be bored and cased to city and GDOT standards, allowing a street cut only when a bore can't be made and the Public Works Department permits it (Municode).
- Under Kennesaw's street repair standards, whoever cuts a city street remains responsible for the backfill and pavement for five years and must repair any settlement at their own expense (Municode).
Your water line (2)
- Cobb County Water System says a leak before the meter is the county's to repair and a leak after the meter is the property owner's; if the meter still spins once every fixture and the main house shutoff are turned off, the leak is probably on the line between the meter and the house (Cobb County).
- Cobb County's code promises users at or below 1,140 feet of elevation at least 20 psi at the meter and makes deciding on, installing and maintaining a pressure-reducing valve the user's sole responsibility (Municode).
Septic systems (2)
- Kennesaw's stream buffer ordinance bars septic tanks and drain fields within the 50-foot undisturbed buffer along a stream and the 25-foot setback beyond it for development the ordinance covers (Municode).
- Cobb County Water System says a water bill with a sewer charge means the home is on public sewer, while a bill without one likely means an onsite septic system, which Cobb & Douglas Public Health regulates in Cobb County (Cobb County).
Other local rules (3)
- Kennesaw's development code applies Cobb County Water System rules to all users of the county system and requires every water and sanitary sewer system to be reviewed and approved by the Water System (Municode).
- Kennesaw's water conservation rules, in effect since January 1, 2024, apply to new water fixtures such as faucets, toilets and landscape irrigation systems but not to existing ones (kennesaw-ga.gov).
- Cobb County's code prohibits connecting roof downspouts, foundation drains or other surface or groundwater sources to a building sewer that drains to the county system unless a discharge permit allows it (Municode).
Water or sewer provider and billing can vary by address in this area. Confirm the serving utility for the property on the water or sewer bill before relying on provider-specific requirements.
