Where the water comes from
Summit Water Distribution Company's main water source is purchased surface water. It buys treated water from Mountain Regional Water SSD, Park City Water System. The seller treats the water, including corrosion control that keeps lead from dissolving out of pipes, while Summit Water Distribution Company is responsible for its own service line inventory and replacement program. It sells water to 4 other water systems: Park City Water System, Gorgoza Mutual Water Co, Mountain Regional Water SSD, High Valley Water Co.

Getting the line replaced
EPA's Lead and Copper Rule Improvements require most systems to replace lead and galvanized-requiring-replacement lines by December 31, 2037. Ask Summit Water Distribution Company whether it replaces the private side for free or with a cost share before you hire anyone. If you want it done sooner, or your utility doesn't cover your side, a licensed plumber can quote it. What replacement costs.
