The Columbia Water Company provides public water service to over 10,000 customers located in Lancaster and York Counties. Operating within a franchised territory that covers Columbia, Marietta, and Mountville Boroughs and portions of West Hempfield, Manor, East Donegal and Hellam Townships, our service territory is divided into two service Divisions: Columbia Division and Marietta Division.
We are regulated by the Pennsylvania Public Utility Commission in the areas of rate setting, billing procedures, dispute resolution, terminations and service expectations. We are also regulated by the Pennsylvania Department of Environmental Protection in the areas of water quality, treatment requirements, and technical standards. Columbia Water Company consistently meets or exceeds all water quality and permit requirements.
Columbia Water Company delivers water to customers through a distribution system that consists of approximately 110 miles of water mains, nine finished water storage tanks, six pumping stations, four wells and 11 pressure zones. Customers in the Columbia Division are supplied water drawn from the Susquehanna River which is filtered and disinfected prior to distribution. Customers in the Marietta Division are supplied water from several deep wells which is disinfected prior to distribution.
Incorporated in 1823, Columbia Water Company has been providing public water service for over 190 years. In 1824 the first reservoir was constructed and Columbia Water Company began installing water mains made of logs. By 1829, Columbia Water Company began using cast iron pipes to distribute water, discontinuing the use of wooded water mains. A second reservoir was constructed in 1860 and a 3rd in 1871. The first filtration plant was built in 1905, which was one of only three in Pennsylvania at the time.
Since its early years, Columbia Water Company has progressed from wooden pipes and ground reservoirs to modern filtration equipment, elevated steel storage tanks and state of the art electronic control systems.
