How do I know if I have a Lead or Galvanized service line at My Location?


  • You can see the City’s service line material Inventory Map near the bottom of the home page on the EvanstonLeadReplacement.org and enter your home address or water billing account number.
  • There are various at-home tests you can complete to assist with determining your material type. Your service line is likely made of either copper, galvanized steel, plastic, or lead. 
  • Plastic pipes are often black or blue and easily recognizable. 
  • You can grab a magnet and if it sticks to the pipe, it is likely galvanized steel, as lead and copper are not magnetic. 
  • Another option is to complete a “scratch test” with a screwdriver and create a small scratch on the service line. If the scratch is shiny and copper in color, your line is made of copper. If it scratches easily and the scratch is shiny and silver, your line is made of lead.
