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.

Brick primary tank refurbishment

We refurbished two brick primary tanks on a wastewater site to extend their lifespan and restore full processing capabilities.

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.

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.

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.

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.

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.

Flood mitigation

Stonbury was contracted by the Environment Agency to complete an initial vegetation cut, followed by other flood mitigation measures on an 800-metre stretch alongside the River Isbourne.

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.

Critical asset repairs

Earlier in the year, we began carrying out repairs to a failing reservoir which showed signs of severe water ingress. The original scope included 180 linear meters of crack repairs. However, following an inspection, this increased to more than 300.

Live repairs to bio-filter beds

We delivered phased brickwork repairs to three bio-filter beds while keeping treatment processes online.

Surge vessel revitalisation

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

Pumping station bridge replacement

A specialist Stonbury team was deployed to undertake the replacement of a bridge for the Environment Agency.

Marine outfall repairs in northeast Scotland

We carried out structural repairs and erosion protection to four coastal outfalls at a wastewater treatment works.

Steel baffle curtain solution

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

Loose liner installation

A loose-lay liner solution has provided long-lasting ingress protection to a steel contact tank within a rapid timeframe.

Service reservoir refurbishment

Stonbury were recently contracted to undertake internal and external repairs to two adjacent clear water tanks located in Central Scotland.
