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.

Sludge holding tank refurbishment

Stonbury were contracted by a framework client to refurbish two sludge holding tanks at a sewage treatment works constructed in the early 1970’s.

Sludge tank foundations

Stonbury was contracted to deliver a concrete slab base and associated groundworks for a new sludge tank on a sewage treatment site in the north of England.

Inlet chamber reconstruction

Due to severe hydrogen sulphide attack, Stonbury were contracted to rebuild a failing inlet chamber at a wastewater treatment works (WWTW), this included the replacement of all defective rebars within the walls.

Hartshill digester refurbishment

Stonbury were recently commissioned to carry out refurbishment works to the gas zone of a Digester.

Steel sludge holding tanks refurbishment

Stonbury, specialist contractors to the Water Industry, have recently completed the internal refurbishment of 2 steel sludge holding tanks.

Filter tank refurbishment

As part of a wastewater framework, Stonbury was enlisted to complete refurbishment works to a filter tank in the north of England.

Start up to waste bag replacement

Stonbury attended an emergency response to replace a Start Up To Waste (SUTW) bag on a wastewater treatment site in the Northwest after the existing bag had failed.

Storm tank construction

Stonbury’s recent storm tank build showcases several sustainable features to reduce maintenance and energy while safeguarding water quality.

Storm tank repairs

Stonbury was enlisted to complete emergency repairs to a storm tank floor after leakage was discovered through several areas in the floor.

Trickling filter column repairs

Stonbury was contracted to make repairs to several column supports for the distribution system surrounding a filter bed at a wastewater treatment site.

Wet well refurbishment

Stonbury were contracted to undertake refurbishment works to a deteriorating waste water wet well.

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 automated system installation

Working on behalf of an Alliance Partner, Stonbury were contracted to complete the installation of an automated system, to control pumping stations that fed into a wastewater treatment works. The scope also included alterations to the existing inlet works to improve flow control and isolation.

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.
