Lift Station to receive upgrades

NORTH BAY, ON – July 13, 2016 – Construction is scheduled to begin July 18, on an essential element of the City of North Bay’s wastewater collection system, the Marshall Lift Station.

The Marshall Lift Station Pump Replacement project includes the removal of one of the old dry well pumps and the installation of a new dry-well submersible pump, the addition of isolation valves for future station expansion, and upgrades to wastewater piping.  The overhaul will improve system reliability and efficiency.

“The Marshall Lift Station is one of the oldest and largest stations in North Bay and handles the majority of the wastewater from the West Ferris neighbourhood,” said Karin Pratte, Senior Facilities and Environment Engineer with the City of North Bay.  “We need to ensure that our infrastructure is reliable and can support the growing demands of the residents, but also that we can depend on it in the event of an emergency, such as a flood or pipe break.”

Along with the significant upgrades, the City will be performing a thorough cleaning of the 40-foot deep wet well.

“During construction the wet well will be drained and thoroughly cleaned to remove any solid materials that have built up over the past 50 years,” explained Pratte.  “While the wet well is offline, a full condition assessment of the concrete will also be completed.”

The assessment will provide the City valuable insight and help with the ongoing maintenance of the station.

“The operation of this lift station is crucial for the City and one of the reasons why Council supported moving forward with the upgrades,” explained Councillor Tanya Vrebosch.  “As our City continues to grow, the infrastructure must grow along with it.”

The lift station is an intended low point in the City’s gravity sewer systems.  The wet-wells in the lift stations act as “holding tanks” for local sewage that gradually and naturally flows in through the gravity sewer system.  As the sewage levels rise, the pumps are engaged to pump the sewage out from the well to the treatment plant.  There are 21 lift stations located throughout the City.

The Marshall Lift Station project is scheduled to be completed before the end of August 2016.
