Whittaker Slough Pumping Station

The Whittaker Slough captures minor system flow from the North Yards and north Industrial Park neighbourhoods and discharges to the Squamish River. The slough is located southwest of the Railway Museum of British Columbia, and has historically experienced flooding during high rainfall events. Due to its location and weather events, the area has high groundwater levels. Dry warm weather conditions together with melting snow causes high water levels in the Squamish River that seeps through the dike and into the slough.

Currently, District staff mobilize portable pumps in response to flooding when the slough requires draining. This process is time consuming and limits staff ability to complete other time sensitive tasks.  

This project will involve construction of a new pumping station, including a new discharge pipe through the Squamish River Dike to convey pumped water.  

Background/Project Information

In 2022, a consultant produced the Howe Sound and Stawamus River Integrated Stormwater Management Plan (ISMP). The plan recommended a new permanent pump station at the interface of the Whittaker Slough and Squamish River be constructed to automate the pumping process. The pumping station will be designed to manage a 100-year storm event.    

The District will be seeking a qualified design consultant in Spring 2025 and with design work and permitted ongoing into 2026. Construction is anticipated in 2027. 

Impacts of Construction

  • Increased noise levels. 
  • Short-term traffic disruptions due to construction activities and vehicles.  
  • Construction is estimated to begin in spring/summer 2027. Work is anticipated to last for approximately 6 months, completing in the fall 2027. 
  • Temporary partial closure of the Squamish River Dike will be required while a new discharge pipe is installed.
