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.
Wilford Bridge refurbishment
Stonbury are carrying out a major refurbishment of Wilford Suspension bridge that spans the River Trent in Nottingham.
Circular service reservoir refurbishment
Stonbury were to complete refurbishment works to a service reservoir dating back over a century to give it an additional 30-year lease of life at a fraction of the cost of building a new one.
WRC filter channel repairs
Stonbury was contracted to carry out repair works at a ‘Water Recycle Centre’ (WRC) to extend the life of the existing filter channels and outlet chamber.
WWTW tank repairs
Following a non-destructive testing (NDT) survey at a WWTW, it was identified that major concrete repairs were required to five tanks, to ensure the plant could remain in use. However, the works could only be undertaken during a full plant closure.
Bridge & spillway refurbishment
The bridge came up in a section10 inspection, which was deemed to require attention. It was decided that a new protective paint system would be applied to the whole structure.
Bank restoration
Stonbury were contracted to carry out comprehensive restoration works to a failing river bank that had become very unstable due to a water main leak.
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.
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.
