The CRD’s East Coast Interceptor and Northeast Trunk Bowker sanitary sewer systems are made from large diameter cast-in-place brick and non-reinforced concrete pipes. Based on results of CCTV inspection, about 1.1km of the system in the City of Victoria and about 1.5m of the system in Oak Bay are deteriorating and must be rehabilitated.
The pipes will be lined from the inside using a trenchless restoration method, cured-in-place-pipe (CIPP) lining to minimize above ground disturbance. Phase 1 of construction which includes cleaning and CCTV inspections will commence in early Spring. CIPP lining is scheduled for the Spring/Summer and the project’s anticipated completion date is December 2024.
