Acciona to build $394M wastewater treatment plant in Canada

April 14, 2017 – Acciona has secured a contract from Metro Vancouver to design, build and commission the new CAD525M ($393.9M) wastewater treatment plant (WWTP) in Vancouver, Canada.

The new plant will replace the existing Lions Gate WWTP, which has provided primary treatment for the greater Vancouver region for more than 50 years.

New wastewater management regulations in Canada require all primary treatment plants in urban areas to upgrade to secondary treatment by 2020.

The new Lions Gate Secondary WWTP will have the capacity to treat 102M litres of wastewater per day under normal conditions and up to 320M litres per day when storm water enters the drainage system.

The facility will be equipped with the following technologies: primary treatment using lamella plates, deep tank activated sludge and thermophilic digestion.

It will also incorporate sustainable features conforming to LEED standards, such as energy efficiency and recovery solutions, water conservation and reuse, on-site storm water management and measures to reduce waste generation.

The biogas produced from the wastewater treatment will be used to generate electricity for the operation of the plant and for its heating requirements.

The latest project, which will receive $212M in funding from the federal government, represents Acciona’s second major water treatment project in Canada. In 2016, the firm also bagged a contract to upgrade the water distribution system and construct a new drinking water plant at Saint John, New Brunswick
