The City of Graham has worked tirelessly in the Boyd Creek drainage area over the past 10 years conducting flow monitoring and rehabilitation projects to reduce the amount of inflow and infiltration that is pumped by the Boyd Creek Pump Station. Running concurrently with these investigations and projects, the City was planning for the need to replace the existing pump station with a new one that increased their pumping capacity, while incorporating a design that would assist maintenance staff with their routine daily operation practices. The existing station was situated within the 100-year floodplain and it was frequently subjected to flooding. AWCK was selected to design a new pump station that was outside of the floodplain and facilitated ease of maintenance. Due to the location of floodplains, the flow of the creek and existing utilities in the project area, AWCK had to work closely with Piedmont Natural Gas for the placement of the pump station so that daily operations of both utilities would not be impacted by the others operations and maintenance. The new station was designed to have a capacity of 567,000 gallons per day and included extending a watermain 2,300 feet to provide water access at the station. The design included bypass pumping as the project area and construction of the new station would require the existing station to be offline. Our design team also provided the City with a bar screen and bypass channel design to facilitate the removal of non-pumpable items, assisting them with the maintenance issues from the past station.
