A special pre-treatment facility will have to be built at the Chilliwack wastewater treatment plant to handle wastewater generated from the future Molson Coors brewery.

The new facility has to be up and running by mid-2018 to enable the plant to accept wastewater from the new brewery in Chilliwack’s food processing park.

Council approved staff recommendation at the Tuesday council meeting to accept Global Water & Energy (GW&E) as the preferred proponent to supply the “anaerobic” wastewater treatment system for the pre-treatment facility.

Molson Coors Canada (MCC) is planning to build and operate a ‘green-field’ brewery in Chilliwack at the site near VedderRoad and Kerr. The term ‘green field’ in this sense means they are building fresh on undeveloped land.

The “high strength” wastewater from the brewery will require “appropriate management to ensure that it does not negatively impact the existing process” at the plant, according to the staff report of April 4.

Molson hopes to begin operating the new brewery by mid-2018. To accommodate the production schedule and to accept brewery wastewater, the new industrial wastewater treatment facility needs to be commissioned and operated at the same time to meet “overall treated effluent quality requirements,” according to the document.

PCL Constructors Westcoast Inc. (PCL) was chosen in February as preferred proponent to build the pre-treatment facility at the wastewater treatment plant.
