The South East Thatcham Flood Alleviation Scheme Blog
The South East Thatcham Flood Alleviation Scheme is a project to build several surface water retaining earth embankments at Dunstan Green Park, public open space near Kennet School, and carry re-profiling of the Harts Hill Road and Francis Baily Primary School and Kennet School playing field. The scheme aims to reduce surface water flood risk to 62 properties at the south east of Thatcham.
We'll upload news and weekly updates here as the scheme progresses.

Floral Way The earthworks has progressed well despite the recent wet weather. The contractor has continued excavating surplus material from Floral Way to form the reservoir basin area. Work has also started on the spillway on the downstream side of the dam. The spillway (or overflow channel) is a structure that provides for the safe and controlled release of excess water from the reservoir to the downstream area. The spillway will be formed using a reinforced grass mats to ensure that the structural integrity of the dam is not affected by erosion if overtopping were to ever occurred. Work on the reinforced concrete outlet structure on the south side of Floral Way is now in progress. The excavations are completed and the reinforcement bars for the new structure are now being installed.

Dunston Green Park The contractor has completed the flood defence wall and associated earthworks at the southern end of the Green. There is an existing oil pipeline that runs through the park that required works to protect it before the one of the bunds that crosses the pipe could be constructed. This involved exposing the pipeline and installing a reinforced concrete protection slab over the pipe. This work was undertaken by a specialist contractor under the supervision of the Oil Pipeline Agency. There are two swales that form part of the Dunstan Green scheme. One of the swales is situated at the north end of the park off Hart's Hill Road and the second one in Marsh Meadows. A section of the footway along Harts Hill Road has been lowered to allow water to flow off the road into the swale. This involved lowering British Telecom cables within the footway. The excavation of both swales are now in progress.

Siege Cross The contractor has continued to excavate material to create the flood storage areas at the north end of the park and to form the bunds which will impound most of the flood water.
