Lead & Copper Rule

WSS REQUESTS PUBLIC SUPPORT IN IDENTIFYING PRIVATELY OWNED SERVICE LINES

The City of Johnson City Water and Sewer Services Department is committed to preserving the quality of our community’s drinking water.

The Department is responding to the Revised Lead and Copper Rule, an Environmental Protection Agency (EPA) regulation requiring that all United States drinking water utility providers inventory service lines to identify materials used by Oct. 16, 2024.

To promptly establish a comprehensive and accurate inventory of water service lines, the Water and Sewer Services Department relies on residential and commercial property owner participation and cooperation.

Plastic and copper are common plumbing materials used in homes after 1989.  In older homes and neighborhoods galvanized or lead may have been used as the plumbing material.  Johnson City banned lead pipes in the early 1970s for new construction and renovations within city limits.

WHAT IS A SERVICE LINE?

The water service line entering your residence or commercial property is commonly located in the basement, main floor, or crawlspace. This pipe may emerge from the floor or it might extend from the side wall. The city typically owns and maintains the service line from the water main to the meter. The service line from the meter to the building is traditionally the customer’s responsibility.

HOW DO I TEST MY METAL PIPES?

Determining the material of your service line is quick and simple.

  1. Scratch the surface of the pipe near where it enters the home with a coin or screwdriver. Observe the color and appearance. Galvanized pipes will be hard to scratch.  Copper pipes will be the color of a penny.  Lead pipes will be easy to scratch and will be gray and shiny.
  2. Place a magnet on the service line. Magnets will not stick to lead or copper.
  3. To listen for lead service lines, tap the pipe. Lead will sound dull whereas copper and galvanized pipe make a sharp sound.
  4. Lead pipes can appear curved or bent with a bulb shape at connecting points.  Galvanized pipes will have threaded fittings.  Copper pipes will have rigid fittings that are soldered together.

Drinking water utility providers must have an inventory of service lines to meet the EPA’s regulation by Oct. 16, 2024. Once you determine your service line material, you are asked to take a brief survey to help the City meet the EPA’s requirement.
