The York Water Company operates as a regulated water and wastewater utility in south-central Pennsylvania, serving over 210,000 residents across more than 50 municipalities in York, Adams, Franklin, and Lancaster counties. The company's core business model involves impounding, purifying, and distributing drinking water, as well as collecting and treating wastewater. Its extensive infrastructure includes two major reservoirs—Lake Williams and Lake Redman—which hold approximately 2.5 billion gallons of water, a 15-mile pipeline from the Susquehanna River, satellite groundwater systems, and multiple wastewater treatment facilities. Operating under the oversight of the Pennsylvania Public Utility Commission, York Water generates revenue primarily through regulated water and wastewater service rates, customer growth, and the Distribution System Improvement Charge (DSIC) used to fund infrastructure replacement. Water utility services account for the vast majority of its revenue, with residential water service representing over 55% of total revenue, followed by commercial and industrial water service at approximately 27%, and wastewater services making up the remainder. Incorporated in 1816, York Water is distinguished as the oldest investor-owned utility in the United States and is renowned for having the longest consecutive dividend payment record in the nation, having paid dividends uninterrupted since its founding.
