Description

This large sewage works was built in 1936, and is surrounded by tall earth banks with a series of sludge lagoons on its western side. The perimeter banks are mostly planted with woodland, but more open areas support grassland with a good range of common wildflowers. The Duke of Northumberland’s River flows through the site in a concrete channel and is followed by a footpath.

Wildlife

The sludge lagoons include areas of bare mud as well as drier, vegetated areas. Tall flowers and willow woodland grow in abandoned lagoons. These provide a range of habitats for birds, including warblers in the scrub and woodland, finches feeding on the weed seeds, and pipits, wagtails and waders on the mud. The Duke of Northumberland's River contains ample submerged vegetation, particularly unbranched bur-reed and water-crowfoot. Insects recently discovered here include the nationally rare and declining phoenix fly.
