3/37 Syphon carrying Hatfield Waste Drain below North Level Engine Drain approximately 580 metres east of A18 - A161 road junction

GV II

Drain syphon. Probably between 1795-1813. Revetment walls probably later C19. Tooled ashlar facing and parapet, brick and ashlar tunnels and revetment walls. Approximately 22 metres long north-south. North and south sides both have 3 segmental-headed tunnel entrances with rusticated voussoirs flanking pointed cutwaters; band and coped parapet carrying C20 railings above. The tunnels slope sharply down below the waterline. Adjoining stone-coped revetment walls to the lower drain flank each side. Hatfield Waste Drain (the southern of the Double Rivers) passes under North Level Engine Drain because it is obstructed by the River Torne. Although drains were cut here by Cornelius Vermuyden in the mid C17, no constructions of that period are visible, and it is likely that the syphon was part of late C18 - early C19 improvements, perhaps those made c1795 by Samuel Foster, or c1813 by Thackray, following John Rennie's proposals. Similar to the smaller syphon at Sandtoft, Belton parish (qv). MHAD "How the Drains Came", Part 2, Appleby Frodingham News, Vol 15, No 4, 1962, pp 28-31.
