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.

South East Thatcham FAS - Week 10

Written on: 14-6-2019

Floral Way

This week the new access road into the site was complete.

The contractor has built a new headwall in the existing ditch that runs to the north of Floral Way.

There is an existing concrete culvert that runs across the Floral way. The existing concrete bridge on the upstream side of the culvert has been removed and the area is being prepared for the installation of a drainage chamber.

This week the contractor carried on with the construction of a drainage chamber, which will drain water from the newly installed land drains.

The existing footpath that was broken out to lay a drain pipe was re-instated and opened to public to allow the construction of a new drainage system along the route of the temporary footpath.

This week the contractor completed the excavation of a trial hole in the footpath to locate the position and level of existing underground services. This will allow us to safely install the two large diameter drainage pipes across the footpath which will connect into the existing surface water drainage system.
