The District of Squamish is undertaking an extensive upgrade of the Mamquam Wastewater Treatment Plant. The WWTP upgrades consist of construction of a new circular bioreactor/clarifier tank, associated piping and a new septage receiving station. Ground under the proposed circular tank has been excavated to approx.1.5m below grade. Impacted utilities under the proposed circular footprint have been decommissioned and relocated.
Challenges/Constraints
The work must be done in a manner that allows the treatment plant to continue operating and meeting the discharge permit throughout the duration of the work.
