Archaeological excavations relating to the construction of the Thanet Supply Line were carried out by Archaeology South-East, Canterbury Archaeological Trust and Wessex Archaeology between 2006 and 2008. (1)

A series of Roman features: gullies, pits, postholes, a wall remnant and remains of a small roadway were uncovered as well as a large quantity of Roman finds detailed in this record. (1)

The report gives a summary of the project brief and a cursory description of the significance of the results as follows:
"From the winter of 2006 to the autumn of 2008 a large programme of archaeological
investigation occurred in relation to the installation of a new Thanet Supply Main by
4Delivery Limited (4D). This water pipeline stretches from the Goshall valley to the
Weatherlees Water Treatment Works on the Isle of Thanet (see Fig.1). The work
took place within a landscape well known for its archaeological importance and would
include such areas as the Wantsum Channel, Richborough Island and the Ebbsfleet
Peninsula. Archaeological activity dating from the late prehistoric to post-medieval
periods was represented at various locations along the pipe-route with late
prehistoric and late Roman features being the most numerous and significant.
The evidence gathered has provided insights into the possible density of late
prehistoric settlement on Richborough Island as well as the nature and probable
southern extent of the late Roman settlement surrounding Richborough Castle. In
addition to these discoveries the deep and linear excavations allowed
paleogeographical analysis into the development of the landscape both as it was in
antiquity and as it is today." (1)
