Allnorth was engaged by the Town of Little Bay as the Prime Consultant to complete upgrades to the pumphouse in Little Bay, NL.

The Town of Little Bay had poor chlorine residuals and pressures due to aging infrastructure in their Line Road pumphouse. This project was intended to upgrade the booster pumps and chlorination equipment to improve water quality in the Town. At the time the water was pumped from a brook that runs adjacent to the pumphouse, however the brook has not met flow requirements during dry spells in the year. It was proposed during an evaluation that an artesian well and storage tank be installed next to the pumphouse to store water and provide a secondary water source.

Upgrades included a new triplex booster pumping system, new chlorine injection equipment, and installation of a new artesian well.

The following factors were identified in an internal climate change measures review:

Drinking Water Supply: As stated above, it was determined that the drinking water supply from a brook was not providing adequate yields. As part of the design, the plan was to store water from the brook to use during dry periods, and to install an artesian well next to the brook as a backup water supply. To ensure the water is safe for public consumption, construction was be completed in a manner in which the booster pumps are 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 will be completed on the building to ensure it is thermal protected.
