Data Center Information
Proposed Data Center and MCMA Water Service Review
Mifflin County Municipal Authority (MCMA) understands that residents have serious questions about the proposed data center, especially related to water use, system reliability, infrastructure needs, and potential impacts to existing customers.
At this time, MCMA has not taken official action related to water service for a data center. MCMA has not received an Intent to Serve Water request or an Application for New Water Service from the developer.
If a formal water service request is submitted, MCMA would review it through its normal technical, financial, legal, and operational process. Any review would include consideration of system capacity, infrastructure needs, regulatory requirements, cost responsibility, and potential impacts to existing customers.
MCMA’s responsibility is to protect existing customers and maintain safe, reliable water service for the community. That responsibility would remain central to any future review.
MCMA’s role is limited to water service review if a formal request is submitted. Land use, zoning, development approvals, and the broader approval process for the proposed data center are handled through other public processes.
MCMA will continue to share updates related to its role as information becomes available.

Environmental Protection Agency (EPA) Lead and Copper Rule Revised (LCRR) Five Key Highlights
MCMA water systems 4440010 and 4440018 (Hawstone) were required to submit a service line inventory to the PA Department of Environmental Protection (PA DEP) annually. 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, 2%, of service lines that were galvanized and requiring replacement (GRR). PA DEP Inventory Response Summary 2026
Each side of the service line requires two (2) inspection points to verify the material. 66% 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. The 2026 letter will be mailed by November 1, 2026.
