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.

Stonbury were recently contracted to undertake internal and external repairs to two adjacent clear water tanks located in Central Scotland.

Sludge holding tank refurbishment

Sluice gate and channel works

Internal & external reservoir refurbishment

Stonbury completed refurbishment works to extend the life of a 40ML underground service reservoir which indicated signs of severe ingress from rainwater.

Inlet chamber reconstruction

Due to severe hydrogen sulphide attack, Stonbury were contracted to rebuild a failing inlet chamber at a wastewater treatment works (WWTW), this included the replacement of all defective rebars within the walls.
