Dorking Water Treatment Works to Tower Hill Water Main, Dorking

Watching brief maintained by N Shaikhley and S Hind of SCAU during the excavation of a pipeline trench and associated easement. This revealed the remains of a 19th century pathway, flints of Late Neolithic to Early Bronze Age date, a sherd of 13th/14th century coarse orange ware and post-medieval pottery sherds, all from the stripped topsoil. Metal detecting undertaken by P and A Vallis recovered a religious plaque dated to the late 15th/16th century, and a medieval copper-alloy key.
