NHER 66692 (Negative evidence record) - Site where limited groundworks revealed no archaeologically-significant remains

December 2021-February 2022. Watching Brief.
Monitoring of groundworks associated with construction of new single-storey plant room, riverside abstraction platform and discharge location.
There was only very minimal ground disturbance at the site of the new plant room, with only the sand footings of the existing brick surface exposed.
An associated drainage trench dug between the new plant room at TG 2286 0890 and the river at TG 2282 0886 revealed a sequence of made-ground deposits. These contained varying quantities of crushed red brick and were almost certainly result of previous demolition and construction activities on the site. Much of this debris had probably come from the buildings shown at this location on 19th and earlier 20th-century maps. The only features of note were two adjacent north-north-west to south-south-east aligned red brick wall footings at TG 2286 0889, only the tops of which were exposed. These were of probable 19th- or early 20th-century date and potentially associated with the iron works that previously occupied the site.
