Diverting flows from Maple Ridge and Pitt Meadows to the Northwest Langley Wastewater Treatment Plant requires two new sewer pipes. Two pipes will extend from the new pump station in Maple Ridge, under the Fraser River, to the treatment plant. The alignment will run parallel to the Golden Ears Bridge. The crossing will be carried out using horizontal directional drilling (drilling a tunnel under the riverbed) to avoid impacts to the river.
Work has been planned in consultation with Fraser River users and permitting agencies to minimize impacts to river activity and the river itself. Metro Vancouver is committed to minimizing the impacts of this project on the marine environment and surrounding habitat.
