Water Service Line Types & Responsibilities

The Cobb County Water System (CCWS) distributes water to our service area via water mains. The system-owned service line is the pipe from the water main to the connection point at the water meter. The customer-owned service line is the pipe from the meter to the building or the meter to the irrigation system. CCWS is only responsible for maintaining the system-owned line. The property owner is responsible for maintaining the customer-owned line.

Determining We Are Lead-Free

CCWS has complied with the U.S. Environmental Protection Agency (EPA) regulations for all public water systems to inventory and submit water service line material data.

Per regulations, service lines are defined into one of four classifications:

  • Lead: A portion of the pipe that is made of lead, which connects the water main to the building inlet.
  • Galvanized Requiring Replacement (GRR): A galvanized service line that is or ever was downstream of a lead service line or is currently downstream of an unknown service line.
  • Non-Lead: The service line is determined not to be lead or GRR through an evidence-based record, method, or technique.
  • Unknown: The service line material is not known to be a lead, GRR, or non-lead, such as where there is no documented evidence supporting material classification.

No lead or galvanized requiring replacement have been identified in CCWS’ service area, which includes most of unincorporated Cobb County and the cities of Acworth, Kennesaw, and Powder Springs.  All service lines in CCWS' inventory have been defined as non-lead. The inventory was developed using historical records, physical inspections, and statistical analyses. Per EPA's guidance, the water service line material for both the system-owned side and customer-owned side of the pipes are labeled in the inventory.

Identifying Service Line Materials

Service line materials found in Cobb County vary depending on the age of the customer’s plumbing, including copper, galvanized steel, and plastic.

 

Water Service Line Material Reporting Form

While no lead service lines have been identified in CCWS’ service area, we understand that you may still have concerns.  Our Water Service Line Material Reporting Form takes you thru a quick visual inspection to help you determine your service line material by checking where the water line enters your home, commonly accessible in the crawlspace, basement, or garage.  Simply follow the prompts, select the material that your service line is made of, and upload a picture to verify the pipe material.
