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.
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.
River survey
Stonbury recently completed a comprehensive river survey in the South West of England, to provide the client with a better understanding of the fish populations within a local river.
Invertebrate surveys
Stonbury completed two invertebrate surveys on the River Avon to sample above and below discharge points, using a Yorkshire Pattern airlift pump.
