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.
