Molly the Mole completes sewer

摘要

Molly the Mole, Scottish Water's tunnelling machine that has completed a 1.2km stormwater sewer under Airdrie, has been raised from the ground which means the new storm transfer sewer can be connected to the local sewer network and made operational later in the year. The tunnel is over 3m wide and runs as deep as 40m in places. The tunnel will create a relief in times of heavy rain that diverts the water to a new storm tank at the site of the old Airdrie sewage works to the rear of Go Outdoors on Lock Street. The project will lead to improved water quality in the South Burn and will reduce the risk of flooding in Cairnhill Road at the railway station. In addition eight nearby properties will be removed from the flood register. Flows will be transferred via interconnecting pipework from their source, transferred along the tunnel to a storm tank, thereafter storm flows discharge to the North Calder water.
