There are approximately 1,400 properties at risk from this section of the River Tame, including 950 residential properties. The Environment Agency, supported by Birmingham City Council, is currently carrying out work to repair and improve existing defences and build new ones. This includes increasing the capacity of an existing flood storage area in the Sandwell Valley.
Phase 1 of the scheme was completed in spring 2017, bringing a new flood wall and flow conveyance improvements through Witton and down to Witton Gravelly Industrial Estate.
Preparation construction work for Phase 2 started late January 2018. The work here will increase flood storage in the Forge Mill area.
We are now starting construction on phase 2 of the scheme, providing additional flood storage at Forge Mill in Sandwell Valley which lies upstream of Perry Barr and Witton and will control the passage of flood water downstream.
Until May 2018, work will continue on preparing for the main scheme construction to start. The main aspects of this phase include the building of the new embankment, installation of the river outlet and temporary re-diverting the river.
To increase the amount of flood water we can store in the Sandwell Valley, we will build a new embankment to the east of the existing lake. The embankment will run from north to south and cross the river channel. Where it crosses the river an outlet structure will be installed, along with a spillway, allowing us to manage the flow of water when necessary. When river levels rise, the gates of the outlet structure will be closed, stopping water from flowing downstream and storing it behind the new embankment.
In very large floods the area of stored water will extend back up the valley to Forge Mill Farm, increasing the water in the existing flood storage lake. Operation of the gates will react to river levels downstream in Witton to make sure that the gates are not closed until they are necessary to stop flooding of houses and businesses.
The Environment Agency has been engaging with the community throughout scheme construction. There has been a number of public drop-in session, community newsletters and face to face meetings.
Phase 2 public drop-in events were held at Forge Mill Farm visitor centre on in January and February 2018. We are currently working on setting up another event in the near future.
