Columbia Water Company | Plant Renovations

Founded in the mid-1800s, the Columbia Water Company (CWC) operates a historic water treatment facility along the Susquehanna River. The plant features several structures on the state’s Historic Register dating back to 1849 and is located in the flood plain. While mitigating strategies have been implemented to locate critical equipment out of the flood plain and a floodwall has been constructed, CWC recognizes the unique historic significance and landlocked nature of the plant which necessitated innovative approaches to meet increasing demands.

Buchart Horn Architects provided architectural design services for the renovations and additions to Columbia Water Treatment Plant in Columbia, PA. The historic facility was originally constructed in 1849 and resides on the eastern shore of the Susquehanna River.

Renovations to several of the original structures on site, in addition to several new buildings, were presented to the Historic Architectural Review Board for approval prior to construction. Existing support structures were modified to support the water treatment process by lifting all essential equipment out of the floodplain. Traditional brick detailing, copper gutters, and wrought-iron fences were used to balance new construction with existing conditions. New site work included security fencing and a concrete ice wall with a brick finish to protect vital equipment from floating ice.

We have been impressed by [BHA's] ability to produce high quality work, on time, and within budget. We appreciate [BHA's] responsiveness to issues that arise during design, permitting and construction. This work ethic is the reason we have work with Buchart Horn on many projects and plan to do so in the future.
