Water Service Line Inventory
The City has created a map to show information about water service line material. This map is a living document, meaning that the information is to the best of our knowledge and as the City gathers more information, updates will be made - a minimum of two per year. If you have any questions or concerns, please contact Customer Service at 517.676.9155 or info@mason.mi.us.  
The City of Mason makes no warranty, expressed or implied, regarding the accuracy, completeness, or usefulness of the information presented. Users of this information assume all liability of its fitness for a particular use. 

The State of Michigan's Lead and Copper Rule (LCR) requires communities to locate and prioritize eligible pipes for replacement. The LCR requires the city to complete a service line material inventory of all public owned water service lines. The City of Mason, when possible, is coordinating service line replacements with water main and road projects for efficiency and to reduce disruptions.
