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.
Bank reinstatement and erosion protection
Stonbury delivered a long-lasting hybrid green engineering solution to re-shape and stabilise a section of riverbank after the existing sandstone retaining wall had eroded.
Bank re-profiling
Stonbury carried out the re-profiling and strengthening of 30 linear meters of bank, which had become unstable due to tidal water.
Baffle wall replacement
Due to the presence of Chrysolite Asbestos inside a drinking water contact tank, Stonbury were contracted to remove a contaminated baffle wall and it’s supporting steel structure. The wall was to be replaced with a new thermoplastic baffle curtain.
Aqueduct conduit bridges waterproofing
Stonbury Ltd carried out an innovative internal waterproofing system to a total of eleven conduit bridges bringing pre-chlorinated water from Lake Thirlmere to Bolton for distribution to the Manchester area.
Aerial tree works
Stonbury was contracted to reduce forty-nine Lombardy poplars located outside an operating office which were posing a public safety hazard.
Access track installation
Stonbury was contracted to construct a new trackway to improve access to a pumping station and extend the existing turning area.
Access platform
Stonbury was asked to fabricate and install a bespoke access gantry, fencing, ladder and gate at an outfall in Bristol due to unsafe access for maintenance teams.
Abandoned reservoir conversion
Stonbury was contracted to repurpose a redundant 1950s-built raw water reservoir into a potable water service reservoir after increased demand called for urgent new capacity.
