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.

Sludge tank foundations

Stonbury was contracted to deliver a concrete slab base and associated groundworks for a new sludge tank on a sewage treatment site in the north of England.

Headwall replacement

Stonbury has been contracted by the Environment Agency to replace the headwalls on a storm water drainage pipe in an embankment that had become destabilised by natural erosion.

Staircase schemes

To address the issue of safe access across several sites for a framework client, we recently completed a scheme to install new access staircases and handrails to tanks, where any existing staircases were not meeting client standards, or none were present.

Steel bridge fabrication & installation

Stonbury was commissioned by the Environment Agency to design, fabricate and install a new steel footbridge over the river at Iwood Gauging Station.

Fish counter installation

Stonbury was engaged by the Environment Agency to fabricate, install and renovate multiple fish counters, an eel pass and access structures at two nearby locations on the River Avon.

Steel tank refurbishment & roof replacement

Stonbury was contracted to refurbish and replace the roof on an above-ground, modular bolted glass-fused-to-steel (GFS) tank.

Stepped access design, fabrication & installation

A client asked Stonbury to stabilise the banks at a monitoring station on the River Isbourne to improve the safety of the access to the river bank.

Storage lagoon construction

Stonbury recently completed the construction of a new storage lagoon in East Yorkshire.

Storm tank construction

Stonbury’s recent storm tank build showcases several sustainable features to reduce maintenance and energy while safeguarding water quality.

Fill point injection hatches

A client approached Stonbury to produce a hatch solution that would eliminate the risk of potable water contamination during tankering operations.

Emergency bank stabilisation works

Stonbury delivered emergency bank stabilisation works as part of a new River Restoration Framework in the north of England.

Trash screen fabrication & installation

Stonbury was asked by North Somerset Council to design, fabricate and install a new trash screen at an underground river culvert in Clevedon, Somerset.

Eel pass fabrication and installation

Stonbury were asked to investigate the use of hydraulic ram pumps as an alternative to electrically powered pumps for the Environment Agency, who required the installation of an eel pass on a crump weir in Bristol.

Water sample tap cabinets

Stonbury’s civil engineering division completed the installation and refurbishment of regulatory sample taps as a part of a minor civils package for an existing reservoir refurbishment framework.

Water tower steel roof fabrication

Stonbury were tasked with a refurbishment project for a Water Tower built in year 1910 in South East London.

Water tower valve replacement

Stonbury was pleased to deliver replacements to several gate valves within a water tower during a four- week programme.
