Granville Township Supervisors Meeting - MCMA Project Presentation
Thank you for attention and questions during the meeting. Based on a primary concern/question "do we have a plan to protect today's customers as well as new customers and future businesses?"
To help answer that, we’ve added two big “what‑if” numbers to our planning: a possible data center that could use about 500,000 gallons a day, and a voluntary 2,000,000 million gallon per day MCMA voluntary water reserve. Including these estimates will help us make sure we can grow responsibly while still providing reliable service to existing and new customers.

More Information on the Letter From MCMA
Environmental Protection Agency (EPA) Lead and Copper Rule Revised (LCRR) Five Key Highlights
REQUIRED NOTIFICATION LETTER ISSUED November 14, 2024, to ALL MCMA Customers
MCMA water systems 4440010 and 4440018 (Hawstone) were required to submit a service line inventory to the PA Department of Environmental Protection (PA DEP) on October 16, 2024. This is an EPA effort to control lead and copper in drinking water system service lines. The service line is the water pipe from the curb into your house. Click for service line details.
This inventory was generated by reviewing records, construction dates, and visual inspections at each customer residence to determine the material used for the residence service line. Except for MCMA service lines in the distribution system, all service lines are jointly owned by MCMA and the customer. No lead was found on any of the MCMA or customer sides of the service line. There was a small group, 1%, of service lines that were galvanized and requiring replacement (GRR). PA DEP Inventory Response Summary
Each side of the service line requires two (2) inspection points to verify the material. 20% of the service lines could be verified. This was primarily accomplished by construction date; any homes built after the lead ban in 1991 are automatically classified as non-lead. Approximately 80% of the service lines have been identified as non-lead but require the 2nd form of verification. MCMA will continue to update each customer account. Customer will be notified annually if their service line status is unknown or galvanized, requiring replacement.
Please go to the Water Quality Page for more details and links to EPA and other helpful information.
