Wright-Pierce’s 2025 Calendar Series highlights projects featured in our yearly calendar. This month, we’re taking a look at the Finish Water Pump Station project in Concord, New Hampshire.
Project Overview
The new Finish Water Pump Station project at the water treatment plant in Concord, New Hampshire, was designed to replace aging infrastructure located in the inundation zone of an earthen dam. Led by Regional Group Leader Chris Berg and Lead Project Engineer Dan Saulnier, this project involved the design of a new 2,500-square-foot station resting partially on the existing buried clearwell and partially on helical piles with concrete pile caps. This configuration enabled Wright-Pierce to design vertical turbine pumps as the heart of the station, without risking differential settlement across the building.
The project required alterations to the treatment plant’s two half-acre clearwells. This provided an ideal opportunity to install baffling curtains in the clearwell to reduce water age and improve chlorine contact time. In anticipation of future regulatory requirements, the increased chlorine contact time provided by the curtains provides safer water for the community.
About the Photo
Lead Project Engineer Dan Saulnier captured this image of the three, 150-horsepower finish water pumps. When asked about what made the project calendar-worthy, Dan said, “What’s better than a photo of three big pumps pushing clean drinking water out to everyone in Concord?”
Project Impact
This project strengthened Concord’s water treatment system with a modern, energy-efficient pump station built on high ground. The new station will serve the residents and businesses in the city for decades to come.
