Acciona wins $394m contract to build new waste water treatment plant in Canada

CTBR Staff Writer Published 11 April 2017

Spanish conglomerate Acciona has secured a CAD$525m ($394m) contract to build a new waste water treatment plant in Vancouver, Canada.

The contract given by Metro Vancouver includes design, construction and commissioning of the waste water treatment plant in the British Columbia province.

Named as the Lions Gate Secondary Wastewater Treatment Plant (WWTP), the project will feature secondary treatment and energy recovery facilities. It will be a replacement of the existing Lions Gate WWTP which has been in service for over 50 years.

The new Lions Gate WWTP marks the second major water project in the country for Acciona. This is after the Spanish firm’s contract for upgrading work of a water distribution system besides constructing a new drinking water treatment facility in the New Brunswick province at Saint John.

Located about 2km from the old WWTP plant, the new one is planned to have a capacity of treating 102 million liters in a day under normal conditions. While, the same can go up to 320 million liters on a wet weather day when storm water collects in the drainage system.

Acciona plans to deploy the same technologies currently used in other facilities in the Metro. The technologies will be primary treatment through lamella plates, deep tank activated sludge and sludge digestion by the thermophilic digestion method.

Electricity and heat needed to operate the WWTP will be derived from the biogas generated from the waste water treatment.

The new waste water treatment plant will be helped with a $212m funding from the Canadian government through its Green Infrastructure Fund.
