At the Flood and Coast conference, which is only a week away, we will be showcasing our joint venture with JBA Bentley and the projects we work on together.
Since 2013 we have been part of the JBA Bentley joint venture delivering planned and emergency response works for the Environment Agency (EA) and other RMAs under the Water and Environmental Management (WEM) Framework.
A great fit
JBA Bentley delivers Flood Risk Management schemes for our Water and Environmental Management (WEM) Framework with the Environment Agency (EA) and other partners. Within the framework we provide early contractor involvement (ECI), feasibility, design and construction activities on schemes that can vary from flood banks to pumping stations to reservoir improvements.
Projects are located across a wide geographical area – as far and wide as Wales, Cumbria and the East Coast – and with an office in Leeds and new premises in Peterborough, JBA Bentley is ideally placed to deliver them. Each office has co-located design and construction teams working together to deliver projects successfully and efficiently.
One of the EA’s responsibilities is to minimise flood risk to urban areas. We have been working with them on a series of five schemes in the Upper Calder region, including Bacup Road, an A-road particularly susceptible to flooding. To alleviate the problem we are installing new road gullies, inlet and outlet structures and pipework to transfer rain water from an adjacent hill to a nearby brook at 25 sites along the road.
We are also raising existing flood defence walls and refurbishing culverts as part of a flood alleviation scheme at Ulverston in Cumbria. The £2.6million project will reduce the risk of flooding to over 350 properties from Town Beck, which has a history of bursting its banks.
Community engagement is crucial on this project given the proximity of works to residential and commercial properties. A project-specific website has been set up to keep local residents informed, featuring a blog and social media feeds. The team have hosted public open days and drop-in sessions too to engage with the community.
Dams and reservoirs
The EA own and maintain a number of reservoirs across the country; essentially storage facilities to prevent water from reaching urban areas. We have delivered a scheme at Spring Gardens in County Durham, where we have stabilised the dam by drilling and grouting over 850 holes. We also designed and constructed a new inlet channel to re-direct the flow of the river back to its original route.
At Yellow Dam in the Lake District, we have designed and constructed new stilling basins and spillway channel, and upgraded the existing dam, to help the EA control water within the Threlkeld lead mine. An innovative ‘concrete mattress’ was chosen to line the new spillway as it provided a cost-effective solution that eliminated the need for excessive formwork in a tight working area.

Visit us on stand A27 at the Flood and Coast conference to talk to our representatives from both JBA Consulting and JN Bentley.
We will be demonstrating the JBA Trust’s new interactive virtual sand box. The prototype demonstrates many different scenarios including how engineering solutions help reduce flood risk from rivers and the sea.
