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.

Rapid gravity filter tanks

Stonbury were recently contracted to carry out refurbishment works to 22 Rapid Gravity Filter tanks and outfall channels.

Reedbed refurbishment

Stonbury has completed works on a seventh bed as part of an ongoing framework to refurbish sixteen reedbeds on a raw water purification site in Southeast England.
