Columbia Water Co. plant

This is the newly expanded Columbia Water Co. water-treatment plant.

Buchart Horn’s York office and Columbia Water Co. won state honors for a $15.3 million water-treatment plant expansion.

The design engineer and the water company received Diamond Awards for Engineering Excellence in the water resources category from the American Council of Engineering Cos. of Pennsylvania.

The project, which took 18 months to design and three years to construct, doubled the plant’s daily capacity to 4 million gallons, said Dave Lewis, Columbia Water vice president and general manager.

Since the plant sits in a flood plain of the Susquehanna River, the project also relocated equipment above the flood elevation and built barriers to shield buildings from ice floes, among other safeguards.

In addition, the project gives the plant state-of-the-art equipment to improve efficiency while incorporating historic buildings that date to 1849. The project was completed in December 2015, said Lewis.

Columbia Water Co. serves more than 10,000 customers in Columbia, Marietta and Mountville boroughs and portions of West Hempfield, Manor, East Donegal and Hellam townships.
