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.
Tunnel lining works
As a part of an existing framework, Stonbury was contracted to carry out optioneering works to improve the condition and maintenance requirements of an impounding reservoir tunnel.
Loose liner installation
A loose-lay liner solution has provided long-lasting ingress protection to a steel contact tank within a rapid timeframe.
Loose membrane application
Stonbury was contracted to undertake an urgent refurbishment to a reservoir roof, after other contractors were unable to commit to the unusually tight deadline.
M&E & pipework inlet alterations
After Stonbury had completed the internal and external refurbishment of this service reservoir, our client asked us to carry out adaptions and improvements to the inlet pipework.
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.
Outfall structure repairs
Stonbury was contracted to carry out comprehensive repairs to an existing outfall structure situated on a lake in the South West.
Pipe bridges refurbishment
As part of Stonbury’s extensive refurbishment activities to water industry structures, we were recently contracted to look at various steel pipe bridge refurbishment works in and around the London area.
Pumping station bridge replacement
A specialist Stonbury team was deployed to undertake the replacement of a bridge for the Environment Agency.
Rapid gravity filter tanks
Stonbury were recently contracted to carry out refurbishment works to 22 Rapid Gravity Filter tanks and outfall channels.
Reedbed refurbishments
Stonbury were engaged to carry out refurbishment works to a reedbed system at a Water Recycling Centre (WRC) in the South of England.
Reservoir roof refurbishment
Working for a client on an individual tender, Stonbury replaced a roof membrane and all upstands and hatches on a reservoir in Southeast England.
River channel works
Working with an ecologist, Stonbury recently cleared 650 metres of dry channel, including the removal of obstructions to flow.
Internal & external service reservoir refurbishment
Stonbury have completed extensive internal and external refurbishment works for one of our framework clients, to a service reservoir approximately 100 years old.
Roof refurbishment over live water
Stonbury were contracted to refurbish the roof of a live contact tank & high lift sump.
Service reservoir asbestos removal
Stonbury were contracted by a framework client to return to a service reservoir that was initially taken out of service several years ago, after an inspection highlighted asbestos fibre contamination, due to a delaminating asbestos cement inlet main.
Service reservoir refurbishment
Stonbury were recently contracted to undertake internal and external repairs to two adjacent clear water tanks located in Central Scotland.
