United Utilities has appointed Barhale to deliver a key project to improve water quality in the Micker Brook at Bramhall, Stockport. The civil engineering, infrastructure and tunnelling specialist will construct a new detention tank at Bramhall Precinct car park to reduce the number of times the storm overflow operates into the brook, a tributary of the River Mersey. The shaft tank will intercept a sewer running into the existing Briarlands Combined Storm Overflow (CSO). The contract has been awarded as part of the largest investment in wastewater infrastructure in the North West for a century. United Utilities is investing £13bn to protect and enhance over 500km of rivers, lakes and bathing waters whilst safeguarding drinking water supplies for millions of customers. The site sits within an area with a high water table so Barhale and UU have collaborated closely to identify a suitable design solution. It includes diverting an 825mm diameter sewer running at 4m depth to allow construction of a 1,000m3 shaft tank using a 12.5m diameter segmented caisson sunk to an invert depth of 13.3m. Barhale will also carry out the MEICA fit out including new pumps in the shaft, control equipment kiosks, control panels, telemetry systems and incoming power supplies. A dual rising main will be connected to the network upstream of the CSO chamber. Nick Curtis, Regional Director – Northern Region, Barhale said: “The project presents some significant technical challenges because of the location and site conditions and we are pleased to continue supporting United Utilities as part of their wide reaching AMP8 investment programme. “We are already active across several aspects of the programme which are reinforcing the network’s ability to withstand storm events. They include constructing another smaller storm tank near this one in Cheadle and two more in Merseyside. “The investment is aiming to reduce spill rates to fewer than one-in-ten-year events. The completion of the Briarlands CSO programme will be an important step towards meeting United Utilities’ target of reducing spills from storm overflows by 60% before 2030.” Completion is scheduled for early summer 2027.

Barhale has secured a major infrastructure contract from Thames Water to undertake essential refurbishment works at Ashford Common Water Treatment Works in Surrey, helping to safeguard one of the capital’s most important drinking water supplies for years to come. The project will see Barhale reline a key abstraction tunnel that forms part of the West London Abstraction system, which supplies raw water from a network of reservoirs feeding the Ashford Common treatment works before distribution across London. The contract follows detailed inspections carried out by Barhale’s specialist Tunnels & Aqueducts team as part of the mandatory five-year inspection programme. Engineers identified inconsistencies within the Southern Inlet tunnel’s existing glass reinforced plastic (GRP) liner, which, if left unaddressed, could compromise the underlying wedgeblock tunnel structure. Following a successful Early Contractor Involvement (ECI) phase, Barhale worked closely with Thames Water to refine the engineering design and develop practical construction solutions capable of overcoming the significant access constraints created by the site’s complex network of underground tunnels and utilities. Construction will begin with the excavation of a three-metre-deep access point to expose the tunnel’s chimney and riser. Sections of the existing riser will then be carefully demolished to provide safe access to the tunnel invert, located almost 20 metres below ground level. Once access has been established, specialist scaffolding systems will be installed throughout the tunnel, enabling engineers to safely remove the existing GRP liner. The team will then excavate the surrounding grout and concrete before constructing a new reinforced concrete lining designed to restore the tunnel’s long-term structural integrity and resilience. The refurbishment forms part of Thames Water’s ongoing investment in maintaining critical water infrastructure and ensuring the long-term reliability of assets that support millions of customers across the capital. Barhale is already familiar with the site, having previously completed a localised repair within the Northern tunnel following issues identified during earlier proactive inspections. A more comprehensive relining programme for that tunnel is also planned as part of future investment works. The latest contract highlights the growing importance of asset renewal across the UK’s ageing water infrastructure, where proactive inspection, engineering expertise and targeted refurbishment are helping utility providers extend the lifespan of critical assets while maintaining resilient water supplies. By combining detailed structural assessment with specialist tunnelling capabilities, the project will ensure Ashford Common Water Treatment Works continues to play a vital role in delivering safe, reliable drinking water to London while supporting the long-term resilience of one of the UK’s most important water networks.

The Environment Agency has set out plans for a £1.4bn flood defence programme that will accelerate more than 600 schemes across England over the next two years, marking a significant step up in efforts to tackle rising flood risk. The investment will fund a broad mix of major infrastructure projects, smaller repair works and nature-based interventions designed to improve resilience and better manage water across catchments. Several flagship schemes are already progressing, including the £59.3m Bridgwater Tidal Barrier in Somerset, the £37.1m Derby Flood Risk Management Scheme and the £24.3m Kendal flood scheme in Cumbria. These projects form part of a wider pipeline aimed at protecting communities, infrastructure and economic activity from increasing climate pressures. Major flood protection schemes currently in the programme include: Alongside new-build defences, around £260m has been allocated to repair and maintain existing flood assets, including damage caused by recent storms. This represents a renewed focus on improving the condition and reliability of ageing infrastructure after years of decline. The programme forms part of a wider £10.5bn investment plan running through to 2036, the largest flood and coastal protection initiative ever undertaken in England. As well as traditional engineering solutions, the Environment Agency is increasing its use of natural flood management techniques, including measures to slow water upstream and reduce peak flows during extreme weather events. Caroline Douglass, the Environment Agency’s flood director, said the strategy combines hard infrastructure with nature-based approaches to deliver long-term resilience. The scale of the programme is expected to support thousands of jobs across the construction and environmental sectors, while also unlocking development in areas previously constrained by flood risk.

Scottish Water has unveiled a £13.4bn investment programme aimed at protecting and modernising the nation’s water and wastewater infrastructure over the six-year period from 2027 to 2033. The publicly owned utility said the plan is designed to future-proof ageing assets, respond to climate change pressures and sustain service standards, while maintaining some of the lowest customer charges in the UK. Of the total investment, £8bn will be directed towards maintaining and upgrading core infrastructure, including pipes, treatment works and associated assets. The remaining funding will cover essential operating expenditure to ensure services continue to run safely, reliably and efficiently. The programme will be delivered across Scotland, with the utility highlighting its potential to support employment, skills development and regional supply chains. Scottish Water said the plan reflects extensive engagement, with more than 25,000 people contributing feedback during its preparation. Chief executive Alex Plant said the blueprint balances long-term resilience with affordability. He noted that customers had made clear the need to safeguard essential services while ensuring investment remains fair and proportionate. As a publicly owned body, Scottish Water reinvests all income into its network and services. The organisation said its charges remain among the lowest of any UK water utility and emphasised that financial support schemes will continue for households requiring assistance. Currently, more than 53 per cent of customers receive some form of support. To fund the proposed programme, Scottish Water has put forward annual increases in customer charges of 3.3 per cent above CPI. The utility argues that this approach will provide the financial stability needed to address infrastructure resilience, environmental compliance and climate adaptation over the coming decade. The proposals have now been submitted to the Water Industry Commission for Scotland for regulatory scrutiny. A draft determination is expected in June, with a final determination scheduled for October 2026. This will confirm investment levels and customer charges for the 2027–2033 regulatory period, ahead of a detailed Delivery Plan being published in advance of the new cycle.

BarhaleEnpure JV has completed an ?18m phosphorus removal programme at Dewsbury Wastewater Treatment Works (WwTW) in West Yorkshire to help improve water quality in the River Calder. Delivered in partnership with Yorkshire Water, the scheme has achieved a 90% reduction in phosphorus levels in the final effluent at the WwTW, exceeding Water Industry National Environment Programme (WINEP) targets for England. Fourteen existing primary settlement tanks (PSTs) have been replaced with three new larger tanks and two new primary sludge pumping stations. Prior to construction an existing beck was diverted to accommodate the new tanks’ footprint. The project took advantage of off-site manufacturing to precast the concrete wall sections before they were assembled on site to form the new 45m diameter, 8.5m deep (deepest at the central desludge cone) settlement tanks. BarhaleEnpure JV constructed a new chemical dosing plant and installed a UMON4 device to upgrade monitoring to MCERTS (monitoring certification scheme) standards. This confirms that the works is treating permitted flow to full treatment (2,350 litres per second) when the storm overflow is operating. The team also completed process improvements and created a 2.5ha biodiversity and rewilding area. The WwTW, which serves a catchment of 200,000 people, remained fully operational throughout the construction process. Phosphorus is a normal component of domestic sewage, entering the sewer system from products such as shampoos and detergents. It can also enter rivers through agricultural run-off and natural soil erosion, which can be difficult to control. Small amounts of phosphorus are harmless and are essential to many ecosystems, but higher concentrations can become damaging to aquatic life.   BarhaleEnpure JV Contracts Manager Brian Harrold said the joint venture moved into the design and construct phase in the third quarter of 2023 following extensive early contractor involvement. “This has been a relatively long-term project to deliver essential water infrastructure for a large part of West Yorkshire,” he said. “We worked closely with Yorkshire Water throughout and successfully completed and commissioned all the new works on schedule and under budget. “The improvements are already delivering a measurable impact, including better water quality in the River Calder, a healthier and more enjoyable environment for people and wildlife and improved opportunities for recreation.” Philip Lister, Yorkshire Water’s environmental permit compliance lead, said: “Yorkshire Water is committed to looking at innovative ways to improve the operation of our sites to meet our phosphorus removal targets. This particular project adopted a number of measures designed to reduce the carbon impact and speed up the duration of the improvement works. “We have committed over ?350m to reduce the levels of phosphorus going into watercourses at 85 of our wastewater treatment sites across the region in the next five years, continuing the work we began in 2020 – 2025.” Building, Design & Construction Magazine | The Choice of Industry Professionals
