Annacis Island WWTP New Outfall 2021

Construction crews begin to assemble a massive Tunnel Boring Machine, which will weigh more than 500 tonnes and be almost 65 metres long. A new outfall location and diffuser system is being installed for the Annacis Island Wastewater Treatment Plant.

The new pipe is expected to meet the regional growth needs for the next 100 years while ensuring greater seismic resilience and continuous, reliable and safe management of liquid waste. http://www.metrovancouver.org/services/liquid-waste/consultations/annacis-island-wwtp/outfall-pipe-consultation/Pages/default.aspx
