a footpath. Between the river and the canal are the former settling beds of Dolfor Sewage Treatment Works, now maintained as a wildlife haven by the Montgomeryshire Wildlife Trust. The section of the canal from Freestone Lock to Newtown is largely filled-in and the site of the basin in Newtown, together with the last of the route, has become a housing estate. A public footpath follows the route of the canal for most of the distance passing the sites of Dolfor Lock and Rock Lock on its way. The Newtown Pumphouse raised water from the River Severn to the canal, initially using an undershot water wheel to operate two bucket pumps. This was supplemented by a steam engine for times when the waterwheel failed to provide sufficient power. In time, this arrangement was replaced by a diesel-powered pump but pumping was discontinued in the 1940s. The building, which originally had a tall chimney, still exists but is in private ownership.
