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

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.

Railway culvert repairs

Stonbury was awarded a scheme to carry out brickwork repairs to a 50-metre-long Victorian-built flood alleviation culvert under a live railway.

Working with an ecologist, Stonbury recently cleared 650 metres of dry channel, including the removal of obstructions to flow.

Lagoon repairs

As the main contractor for refurbishment works, a framework client required Stonbury to install a cofferdam system and carry out repairs to a settling tank at a water treatment works.

Lagoon repair and refurbishment

To extend the life of two final settlement lagoons, Stonbury was required to carry out refurbishment works, which included repairs to the outfall structure, the installation of an EPDM liners and replacement pipework.

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.

Lagoon refurbishment

A final settlement lagoon required repair and refurbishment work due to wildlife damage and bank slippage, which had caused the lagoon to leak. A ‘Land Drainage’ consent from the local council was required before the works to the channel could go ahead.
