11/5 Amwell Hill Pumping Station

1. 1. 75 (formerly listed under Pepper Hill) II

Pumping Station of 1849 by William Chadwell Mylne (1781-1863) as Engineer to the New River Company. A tall classical building of one high storey facing W. Boiler house in lean-to at rear a little later. Fine yellow stock brick with buff brick gauged arches to arcading on front and sides and to square headed windows. Low pitched slate roof, hipped at front and concealed by a bold stucco cornice with blocking course higher in the middle. Eaves overhang at sides. Raking gable parapet at rear with fat, square chimney, tapering above a projecting band which continues round the building below the eves. Front has triple arcade with plinth and imposts and a recessed sash window with 6/6 panes in each bay - centre one blocked. Small door, and window with slender cast iron bars, in outer bays of S side each with square heads under segmental triple arcade. Taller central round-arched opening on N side with upper part glazed with radial bars, flanked by sash windows in side bays. Large opening presumably lit the steam engine and facilitated its building (converted to electricity in 1944). The earliest extant pumping station in Hertfordshire: built to pump into the New River (Branch Johnson (1970) 100: Pevsner (1977) 150).
