Wastewater Upgrades Construction Underway

The Village of Cumberland is upgrading its wastewater treatment system to meet provincial standards, as well as fulfill environmental goals to remove man-made toxins, restore degraded ecosystems and release safe water into Maple Lake Creek and the Trent River, which flows into Baynes Sound.

The Wastewater Upgrades Project is a result of years of careful planning and community input to develop a sustainable treatment system in a region with unique challenges which include high winter wet weather flows, extremely dry summer conditions and a sensitive downstream habitat.

About the Wastewater Upgrades

The Wastewater Upgrades Project is about improving the treatment provided by the current lagoon system. This project includes two phases. with the lagoon upgrades as the primary focus. Work began in 2022 and is estimated to be complete in late 2025/early 2026.

PHASE 1: Treatment Upgrades: These are the main treatment improvements, to meet provincial effluent and reliability standards – works include:

  1. Improvements to wastewater screening,
  2. Changing the flow path in the lagoons and adding extra aeration
  3. Adding nutrients for phosphorus removal
  4. Additional environmentally friendly disinfection
  5. Ancillary works such as an operator’s building, workshop, improved instrumentation, site security, etc.

PHASE 2: Additional Improvements. These are the additional aspirational improvements identified through the planning process that will improve treatment but are not required by regulation. This includes (for example):

  1. Biochar Media Reed Bed: To be complete in tandem with Phase 1.
  2. Tertiary Filtration: To be complete in tandem with Phase 1.
  3. Wetland Enhancement. Using the reed bed treated water to irrigate an area of the existing natural wetlands for further polishing of the water by dispersed flow into the creek.
  4. Seismic Upgrades: Improving Lagoons by infilling existing Maple Lake Creek channel and regarding berm walls.
  5. Stormwater Treatment Wetland: Improvements to the western wetland ponds to make them a functional stormwater treatment wetland, and passing Mill St. and Cumberland Rd. stormwater through them before reaching Maple Lake Creek.
  6. Maple Lake Creek Improvements: Re-routing and naturalization of the Maple Lake Creek channel by adding to east side of wetland area and introducing natural form weirs and fishways.

What You Need to Know

This is the largest capital project undertaken by the Village of Cumberland to date, with an updated projected cost of $16.7 million for Phase 1 works and $4.5 million for Phase 2. The Village is seeking borrowing approval to cover the project budget increase for Phase 1 works. See the Wastewater AAP Section above.

  • Grants will pay for a significant portion of this project. Here is a breakdown of funding:
    • Canada – BC investing in Canada Infrastructure Program Federal contribution $3.9 million
    • Canada – BC investing in Canada Infrastructure Program Provincial contribution $3.2 million
    • Federation of Canadian Municipalities “Green Municipal Fund” – Loan of $2.26 million and grant of $0.34 million
    • Canada Community Building Fund $2.5 million (see announcement here)
  • This combination of engineered and naturalized systems will have lower operating costs than a traditional mechanical wastewater treatment system.
  • Lagoon upgrades will support future population growth to 7,000 people.
