Willowholme Wastewater Treatment Works, Carlisle: Archaeological Desk-based Assessment

United Utilities propose to put in an application for an extension of the Willowholme Wastewater Treatment Works, Carlisle, Cumbria, including the construction of trickling filters, humus tanks, a sludge storage tank and pumping station, odour control units, and associated pipelines, access roads, and structures. The proposed development is situated to the immediate north of the current sewage works, and within an area of archaeological sensitivity. To the south, and skirting across the south-west corner of the current works, runs the line of Hadrian’s Wall (Site 01; SAM CU2819). Its significance is reflected by its designation as a World Heritage Site, and it is protected as a Scheduled Ancient Monument. Associated features have often been found to the north and the south of the wall, often outside the Scheduled area. As well as the potential for Roman archaeology, recent excavations for the CNDR, further east along the River Eden, have revealed extensive prehistoric remains, indicating potential for other similar remains in the proposed development area. The area also contains sites dating to the post-medieval industrial growth of Carlisle.
