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.

Magnetic vents for access covers

As part of an extensive refurbishment programme, Stonbury have been replacing the push-fit vents used inside security access covers on reservoir roofs.

Media bays

Works were recently completed at two separate Water Treatment Works to increase the aggregate storage capacities.

New build reservoir

As the Reservoir Refurbishment Framework Contractor for South Staffordshire Water, Stonbury had the opportunity to tender for the design and build of a 10Mg potable water storage point at SSW’s Outwoods site, on the outskirts of Burton on Trent.

New build reservoir partition wall

Stonbury were contracted to build a full-height division wall to create two separate compartments inside a potable water reservoir. This was due to the high demand for supply, which meant the tank could not be taken out of service for inspections and maintenance works.

New build transformer concrete bunded base

Due to a flood event inside a high voltage building, which was situated on a Water Treatment Works, Stonbury were asked to relocate the existing transformer onto a new concrete bunded base and waterproof the building to prevent future ingress.

Liquid membrane solution

After a service reservoir was scoped by an external structural engineer and found to show signs of water ingress, Stonbury was contracted to identify and install a solution.

Pipe bridge refurbishment

Stonbury was contracted to carry out refurbishment works to two pipe bridges located on the River Chelt.
