 This was altered in that year, by building a new pumping station at Greenholme, which pumped the Folly Drain into the South Level Engine Drain.The station was built by the Trent River Board for the West Axholme IDB, and contained three pumps, two of diameter, capable of pumping 109 Mld, and one of rated at 29 Mld.The area was affected by the motorway construction programme of the late 1970s and early 1980s, which saw the M18 motorway running along the western edge of the Chase and the M180 motorway crossing it, broadly parallel to the Stainforth and Keadby Canal, but a little further south.
