Lead Service Replacement Program

In 2018, the State of Michigan issued a lead and copper rule that placed new requirements on water supply and distribution systems.  Two of the more significant changes were requirements to complete a distribution system material inventory (DSMI) and replace lead water services on a set schedule.

The City submitted a preliminary distribution system inventory in December 2019 in compliance with the deadline of the new rule; the final material inventory is due in five years.  In order to comply with the final DSMI, the City is conducting point-of-entry inspections to determine service material type where it enters the foundation or structure.  Property owners should expect to be contacted by City staff to arrange a convenient time to conduct this inspection if it has not been completed already.  A small portion of newer constructed homes in the City will not require an inspection because the City has records on file confirming that no lead is present.

The distribution material system inventory will be used to determine the extent of water service replacements.  The State has established varying rates at which water suppliers must replace lead services. Because the City of St. Joseph is in compliance with the Safe Drinking Water Act, we will be required to replace services at a rate of 5% per year starting January 1, 2021.  The City is in the process of developing the lead water service replacement program schedule.

Links to the current DSMI map and a map illustrating the general location of the water service line replacements are provided below.

Free lead testing was offered to eligible water customers residing in the City of St. Joseph have lead or likely lead service lines as identified in the DSMI (Distribution Service Material Inventory).  A searchable map showing eligibility is available at this link: https://portal.sjcity.com/portal/apps/Styler/index.html?appid=b703ffc5ab6d4201800c264e847e7063&lat=42.10205&lon=-86.48343&zoom=13

The program ended on April 30, 2021, as we move into our annual required testing program.  A testing program for services where the private service material is unknown will begin in the fall of 2021.  Call the City of St. Joseph Water Plant at (269) 983-1240 Monday-Friday 8 AM to 5 PM or email This email address is being protected from spambots.
