We completed a major refurbishment project at a strategically important water treatment works, extending the lifespan – by over 10 years – of a critical asset whilst mitigating the need for a costly and carbon intensive new build alternative.
Storm tank installation
A 55 cubic metre sectional-steel storm tank with sustainable features was installed at a wastewater treatment site to comply with regulations to cut sewage overflows. The works significantly reduced running costs for our client and allowed them to meet specified carbon reduction targets while increasing stormwater capacity to help protect local waterways for decades to come.
Large-scale weir removal
On behalf of the EA we successfully opened 340 miles of catchment in the largest project of its kind – in the country – by removing a 70 meter wide, 900 year old medieval weir. Removing the weir significantly improved fish migration, spawning grounds and habitat. Fallen water levels have also allowed natural ecological processes to recommence.
Fish rescue and relocation
Stonbury is pleased to have completed a fish rescue and relocation on behalf of the Environment Agency to protect fish from harm prior to scheduled de-silting works.
Flood alleviation scheme
A village in East Devon was subject to regular flood events due to the low capacity of the surrounding drainage ditches.
Gauging station equipment installation
Stonbury was instructed to design, manufacture and install a bespoke two-headed, pole-mounted radar bracket to measure water height levels at a gauging station in the midlands.
Harbour desilting & flood gate release
Stonbury was asked by the Environment Agency to propose and execute a solution to free a set of floodgates within a harbour on the bank of the tidal River Severn.
Natural flood management & habitat enhancement
Working on behalf of a National Park, Stonbury installed natural flood defences designed to enhance biodiversity within an upland river.
New build tertiary treatment plant
The Stonbury civil engineering branch completed works as part of the final stages of a large turnkey construction project for a framework client.
Sludge tank refurbishment
As part of a significant multi-site wastewater treatment works framework, Stonbury was pleased to deliver the refurbishment of a brick sludge tank, returning the vital asset back to service.
Steel baffle curtain solution
A new stainless steel and Flagon curtain baffle wall solution was delivered by Stonbury’s specialist in-house team.
Storm tank upgrade solution
Stonbury has been working with water companies across the UK to deliver solutions that ensure its clients comply with new Environment Agency (EA) storm tank regulations.
Surge vessel revitalisation
Stonbury was recently tasked with revitalising a surge vessel to extend its operational life and ensure compliance with industry regulations.
Tunnel lining works
As a part of an existing framework, Stonbury was contracted to carry out optioneering works to improve the condition and maintenance requirements of an impounding reservoir tunnel.
Wastewater outfall repairs
Stonbury was contracted to carry out concrete repairs to several joints along a wastewater outfall located on the North Sea. In addition, the scope included the installation of new foundation pads and a riprap wave protection barrier.
