Large-scale reservoir refurbishment

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.

Preventing flooding with embankment repairs

We collaborated with our client to complete essential bank stabilisation works to prevent flooding in the surrounding area.

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.

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.

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.

Larinier type fish pass installation

Stonbury were commissioned to install a fish pass at Crumpwood Weir, near Uttoxeter, which was identified as a significant barrier to fish migration.

Chalk stream restoration

A local Rivers Trust contracted Stonbury to restore a section of an SSSI-designated chalk stream in Hampshire to a more natural, ecologically resilient state.

Reedbed refurbishments

Stonbury were engaged to carry out refurbishment works to a reedbed system at a Water Recycling Centre (WRC) in the South of England.

Bank reinstatement and erosion protection

Stonbury delivered a long-lasting hybrid green engineering solution to re-shape and stabilise a section of riverbank after the existing sandstone retaining wall had eroded.

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 mitigation

Stonbury was contracted by the Environment Agency to complete an initial vegetation cut, followed by other flood mitigation measures on an 800-metre stretch alongside the River Isbourne.

Improving gauging station access

In collaboration with the Environment Agency, Stonbury’s environmental team installed specially-designed access steps at a gauging station in Devon.

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.

Badger protection and re-location works

In an effort to maintain flood defence abilities of a drain that had been categorised as requiring further action to sustain its level of flood risk into the future, Stonbury completed works to safely relocate and exclude badgers from an existing sett.

Pumping station bridge replacement

A specialist Stonbury team was deployed to undertake the replacement of a bridge for the Environment Agency.

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.
