Allnorth was engaged as the Prime Consultant to replace the booster pumps in the pumping station on Newtown Road in the Town of Bishop’s Falls. The project was required due to low pressures and low chlorine residuals in certain parts of Town.

The Town of Bishop’s Falls receives water from the Exploits Valley Water Treatment Facility. The water receives secondary disinfection at a pumphouse on New Bay Road, after which it is distributed between three separate mains to service the Towns of Grand Falls-Windsor, Bishop’s Falls, and Botwood. As it is one of three recipients of the water, the source disinfection cannot be adjusted.

Therefore, the Town of Bishop’s Falls needed to complete all adjustments within their Town. Allnorth was commissioned to study the chlorine residuals and develop a way to boost pressures as well as chlorine residuals within the Town. Allnorth conducted the analysis and developed a new boosting system for the existing pumphouse and installed flushing hydrants at the ends of certain water lines to increase chlorine residuals.

Climate Change Measures – Allnorth completed an informal review of the project using the ‘7 Steps to Assess Climate Change Vulnerability’ process. The main factors that were relevant to this project were as follows:

  • Drinking Water Supply: This project consists of upgrades to the drinking water network; however, the supply remained untouched. To ensure the water was safe for public consumption, construction was completed in a manner in which the booster pumps were replaced and tested at different times to ensure a free flow of chlorinated water.
  • Winter: The existing booster pumphouse had been experiencing high quantities of condensation and minimal freezing. In addition to replacing the booster pumps, upgrades were completed on the building to ensure it is thermal protected.


  • Pre-design investigations (sizing of booster pumps)
  • Design development
  • Project management
  • Tender/contract administration
