Case studies of our projects across the UK.
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.
Flood bank slippage repair
Stonbury was called in by the Environment Agency to solve a challenging problem. A mud flood bank on the River Avon at Pill had slipped, threatening the integrity of residential flats that were situated alongside a stretch of the tidal reach. The void had to be infilled with stone on a geotextile base to re-establish the integrity of the bank, however, access to the site proved to be quite a challenge.
Debris clearance
Stonbury was contracted by the Environment Agency to clear debris from a ‘dragon’s teeth’ flow device, that has been designed to break up and dissipate the water flow before a bend in the river and to protect strategic pumping assets. The scope also included strimming along a 300m stretch of the riverbank.
