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
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.
Improving filter performance with PM cleaning
Using our proprietary PM77 cleaning system, we successfully removed inorganic build-up from the underdrain of a secondary manganese filter at a water treatment site in Scotland.
Coastal erosion works
Working in partnership with the Environment Agency, we delivered a targeted shingle redistribution scheme at Preston Beach, Dorset, to restore the beach’s protective function.
Improving gauging station functionality
Supporting the Environment Agency on its AOMR Framework, we completed essential gravel removal and relocation at Thorverton Gauging Station in Devon.
Scum board replacement
Delivering a scum board replacement and access platform installation on a sewage treatment site, our innovative methodology delivered maximum value for our client.
ROV Spot Sampling
Stonbury company Panton McLeod demonstrates the importance of utilising technology that enables the assessment of water quality within the body of clean treated water service reservoirs.
Contact tank clean and repair
Collaborating with Stonbury company Panton McLeod, we delivered cleans and repairs to three WTW contact tanks on a potable water treatment site in the Northeast.
Reducing carbon in riverbank maintenance
Stonbury has returned to the River Severn to complete embankment maintenance for its sixth year, introducing new measures on behalf of the client to significantly reduce carbon emissions.
Pipe bridge refurbishment
Stonbury was contracted to carry out refurbishment works to two pipe bridges located on the River Chelt.
Wave wall investigation
Stonbury was contracted to complete investigation works into the condition of an existing wave wall structure on an impounding reservoir.
Fish rescue and relocation ahead of scheduled desilting at Trews Weir
We supported biodiversity protection on the River Exe with a specialist fish relocation, allowing planned desilting works to proceed safely under the AOMR framework.
Reinforcing coastal wastewater outfalls on the North Sea
We delivered urgent structural repairs and erosion protection to safeguard a wastewater outfall at risk of collapse.
River embankment maintenance
After a successful past three years, Stonbury was again selected by the Environment Agency to complete essential maintenance works to 35 kilometres of flood embankments along the River Severn.
Riverbank erosion works
Stonbury was enlisted to install emergency erosion control measures to a riverbank in Northwest England after a section had collapsed.
Flood defence badger exclusion and mesh works
We delivered mesh installation and sett relocation to protect flood infrastructure at a site which is part of an area identified for sustained flood risk management.
Boardwalk refurbishment
Stonbury was contracted by the Environment Agency to refurbish the boardwalk alongside a river which flows through a public park in the midlands during a four-week programme.
Improving water quality compliance
Companies within the Stonbury Group were enlisted to provide a chemical clean and baffle curtain modifications within a treated water reservoir to reduce the potential presence of bacteria and remove dead spots within the tank.
