Vinci Construction, via its subsidiary Bessac, and in a general partnership with the Canadian Pomerleau company, has won a contract to build new pipelines for the Annacis Island wastewater treatment plant near Vancouver.
The CAD184 million (US$140 million) contract covers construction of two 40m deep access shafts with 16 and 7m diameters respectively and two segment-lined tunnels with lengths of 580 and 200m and an inside diameter of 4.2m.
The project, set for handover at the end of 2023, is financed by Metro-Vancouver, which comprises 21 municipalities, one Electoral Area and one Treaty First Nation.
It is part of the expansion of the Annacis Island wastewater treatment facility, one of the region’s largest. It has a treatment capacity of nearly 175 million m3 per year, equivalent to the consumption of a population of one million.
This is Bessac’s first contract in the Canadian province pf British Columbia.
