Border Archaeology undertook this archaeological desk-based assessment on behalf of Bristol Water to determine the nature of the archaeological resource within the vicinity of a 2km section of water mains pipeline at Long Ashton, Bristol, prior to rehabilitation works. The pipeline extends north from the southern end of Keeds Lane, Long Ashton (NGR ST 5364 7024), crossing a modern forestry plantation (Providence Plantation) and then proceeding northwards along Providence Lane/Longwood Lane before reaching the Beggar Bush Reservoir at NGR ST 5385 7108 (fig.1). Copies of this assessment will be supplied in the first instance to Bristol Water for their consideration.
