LACTALIS selected SADE to design and build a system to discharge process water from the Cheddar production plant of its Scottish subsidiary, the Caledonian Cheese Company, into the sea. An 11km, 250mm-diameter HDPE sealless underground pipe was built. 400m of directional drilling was carried out downstream, to enable the pipe to descend a 45m black granite cliff and reach the Irish Sea. There were seven reroutings to avoid 32 families of protected badgers living along the route. A pumping station, equipped with two 90kW, 120m3/h capacity (at 14 bar) stainless steel duplex pumps, was built upstream.
