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.

Service reservoir floor refurbishment

A framework client contracted Stonbury to carry out refurbishment works to a service reservoir floor where soft concrete issues had been identified. The floor surface had been deemed unsafe to walk on due to multiple slips, trips and falls inside the tank.

Lake restoration

Stonbury were approached by a private client to restore a neglected lake and its surrounding area. The lake had accumulated a considerable amount of silt build up and the grounds had become highly vegetated, offering no vehicular access and was prone to flooding.

Marine outfall repairs

Stonbury was contracted to design and deliver repairs to four outfalls which form part of a wastewater treatment works in the northeast of Scotland.

Application of bonded membrane to cylindrical columns

A client approached Stonbury to complete a routine flood test as a part of a flood test and cleaning programme.

Slow sand filter refurbishment

Stonbury has recently completed the installation of a new floor and sandbar set during an ongoing project to increase the lifespan of a slow sand filter.

Spillway repair

We completed repairs to a spillway by installing a new concrete support structure as an effective replacement for degraded gabion baskets. The spillway was built in 1906 and is essential to the effective operation of the nearby reservoir which holds 247 million litres of water.

Refurbishment of treatment tanks

We advised our client to avoid an unnecessary, carbon heavy rebuild, by carrying out refurbishment works and live repairs to 6 treatment tanks within a wastewater treatment facility which remained operational throughout.

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.

Bio-filter live repairs

Stonbury completed masonry repairs to three bio-filter beds in the South of England. The works took place in sequence to allow the bio-filters to remain in service for the twenty-week construction program duration.

Natural flood management & habitat enhancement

Working on behalf of a National Park, Stonbury installed natural flood defences designed to enhance biodiversity within an upland river.

Sludge tank refurbishment

As part of a significant multi-site wastewater treatment works framework, Stonbury was pleased to deliver the refurbishment of a brick sludge tank, returning the vital asset back to service.

Steel baffle curtain solution

A new stainless steel and Flagon curtain baffle wall solution was delivered by Stonbury’s specialist in-house team.

Storm tank upgrade solution

Stonbury has been working with water companies across the UK to deliver solutions that ensure its clients comply with new Environment Agency (EA) storm tank regulations.

Surge vessel revitalisation

Stonbury was recently tasked with revitalising a surge vessel to extend its operational life and ensure compliance with industry regulations.

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.
