8/124 Syphon carrying South
Level Engine Drain under
the River Torne
approximately 200 metres
south-east of Pilfrey

- II

Drain syphon. c1813 by Thackray. Tooled ashlar facing and parapet. Brick
tunnels. Approximately 50 metres long from north to south. North and south
sides have 3 segmental-headed tunnel entrances flanking a pair of rounded
cutwaters, with a band and coped parapet between rectangular end piers. The
tunnels slope sharply down below the waterline. Carries the combined waters
of South Level Engine Drain and Folly Drain below the former course of the
River Torne (now disused) and the A18 road. The River Torne was cut between
1629-39 by Cornelius Vermuyden; South Level Engine Drain [prior to 1858
known as the New Idle River] was cut as part of the improvements made by
Samuel Foster 1795 or shortly after. The syphon appears to be part of
further improvements made by Thackray in or after 1813, following John
Rennies proposals. The upper drain (River Torne) has since been diverted
and the original course now fallen into disuse. Other drain syphons survive
at Sandtoft, Belton parish (qv), and south of the A18, Crowle parish (qv).
