Michigan's LCR requirements

• The LCR requires water supplies and systems servicing more than 50,000 customers to create a Water System Advisory Council. 
• Ann Arbor Water currently serves a population of 127,885 customers.
• ​As already stated, Michigan's LCR requires communities to locate and prioritize eligible service lines for removal. 
• This includes submitting a comprehensive inventory of all service line material for publicly owned and privately owned water service lines by October 2024
• ​The LCR requires the replacement of:
• all lead service lines 
• ​all galvanized service lines that were once connected to lead via a lead “gooseneck"
• ​​

  

  
  

​The ​Lead and Copper Rule & Ann Arbor Water

• Ann Arbor once used a small piece of lead pipe to connect galvanized water service lines to water mains. 
• The piece is known as a lead “gooseneck".
  
• These were used on service lines installed before 1927 and on some lines installed between 1942 and 1945. 
• ​All known lead goosenecks have been removed. 
• Additionally, there are no known lead service lines in use in Ann Arbor.
• Ann Arbor Water created a preliminary service line material inventory using information gathered during the city-wide water meter replacement project.
• Using this data, replacements of galvanized service lines that were once connected to lead began in 2021. 
  
• We continue to replace lines at a rate of 5% per year.
• Residents will get a letter when their service line is scheduled for replacement. 
• ​​When possible, the city will coordinate service line replacements with water main and road projects to reduce road and service disruptions. 
• The city will also replace leaking service lines as they are discovered. 
• ​Please be patient and remember we are coordinating replacements with road projects, so we do not have a long-term detailed schedule.
  
• The city has created a dashboard and map for the public to view information about their service line material. The map shows service lines that have been replaced, service lines that are eligible for replacement and service lines that still require in-home verification. 

1. Open the dashboard & map. 
   
2. Use the search function on the map to find your address and zoom into your address located within the map. 
3. ​If the circle isn't completely filled in, your line has not been inspected. 
• ​​​​​​If you haven't had your line inspected, please send an email to leadandcopper@a2g​​ov.org​ with your address and contact information and staff will reach out to you.
