Barhale has extended its role in the maintenance of the Thames Water Ring Main (TWRM) after securing works to replace almost 100,000 white caps in the tunnels between Kempton and Kew. The £1.47M project will see the civil engineering and infrastructure specialist isolate, drain, clean and inspect two sections of the TWRM from the Kempton shaft to the Mogden shaft (6.875km) and from the Mogden shaft to the Kew shaft (4.820km). Barhale will then replace the existing push-fit caps covering the lifting eye sockets on each tunnel plate with new, screw-fit types. The Thames Water Ring Main was built between 1988 and 1994. It is 2.5m diameter and 80km long and is a critical part of London’s water infrastructure carrying around one-sixth of the capital’s daily water demand. Access to this section of the Ring Main is only possible through access flanges at the Kempton, Mogden and Kew shafts so some enabling works may be required. Barhale regional manager, John Prendergast described the works as an important element in the ongoing maintenance of the Ring Main “We have worked alongside Thames Water on the Ring Main for many years and we are pleased to be extending our long-standing relationship with this latest programme.” he said. “The close relationship between the two teams and our collaborative approach continues to yield positive outcomes for customers – not only in programme delivery but also in terms of the longer-term benefits where we are improving the network’s resilience and safeguarding the future supply of drinking water to London.”
Brett Martin has provided its new StormCrate55 modular crates for an underground attenuation tank designed to control stormwater and address surface water run-off as part of the redevelopment of a business park in Cheshire. Located in Wincham near Northwich, the Blue Group site at the New Cheshire Business Park features offices, a workshop and space for up to 20 waste handling machines. In order to manage surface water on the site during periods of heavy rainfall, Engineering Services, working on behalf of Blue Group, collaborated with Brett Martin on a design which incorporated the StormCrate55 system – an engineered Sustainable Drainage System (SuDS), to create a 325m ³ storage tank below a parking area. Due to space limitations and drainage layouts on site, Engineering Services found the dimensions of the StormCrate55 perfect for this project. With each crate capable of storing up to 237.5 litres of water, Brett Martin’s technical experts were able to offer technical guidance for the design of an attenuation tank and underground storm drainage pipe layout to suit both the site landscaping and tank storage requirements and allow stormwater to be managed on an area where staff cars and light goods vehicles are to be parked. With Brett Martin offering a complete package, the attenuation tank was installed in a short timescale by contractor Catalogue Engineering. As each crate weighs only 15.5kg they were easy to lift by hand and simple to connect together using connectors and shear pins in a brick bond pattern and at three layers deep in parts. Commenting on the specification, Terence McGeary of Engineering Services said:” The site in Wincham had some specific constraints in terms of space, topography and pipe placement. Despite these challenges, we were delighted with the technical support and the complete package provided by Brett Martin leading to the specification of the StormCrate55 system for this project.” As with the application at the Blue Group site, one option is to surround the StormCrate55 system with an impermeable geomembrane to create a sealed underground attenuation tank. The outlet from this tank is then controlled to facilitate a slow release of the stored water back into the drainage system. StormCrate55 can also be wrapped in a permeable geotextile material to create an infiltration system which allows stored water to slowly seep into the surrounding ground and back into the water table over a period of time. Available for delivery to site with a fast two-to-three day lead time, StormCrate55 is seen as one way to manage rainfall on a site, reducing the risk of surface water flooding and avoiding the problems associated with an overloaded sewer system. Ideal for a range of applications including landscaped areas, pedestrianised spaces and playgrounds, Brett Martin’s StormCrate55 will ensure this business park will have a proven stormwater and drainage solution, ensuring flood protection for the long term.

Barhale has landed a duo of new contracts from South Holland Internal Drainage Board (IDB) to install, reinforce and renovate key drainage works in Lincolnshire. The infrastructure and civil engineering specialist will undertake works at two locations across the southern part of the county: First, at Fleet Haven Pumping Station, Barhale will renovate the inlet, outfall and surge chamber. The station removes water collected by the drains to the sea and is essential for the protection of the surrounding land and villages which typically lies one metre below high sea level. Unusually, because of its location next to RAF Holbeach, the site will undergo “sweep and watch” protocols for unexploded ordnance before and during any excavation work. Second, a renovation programme at Westmere Pumping Station/Sluice will address the poor structural condition of the outfall into the River Nene, ensuring the continued operation of the station, which caters for the discharge of surface water from the village of Sutton Bridge and the surrounding agricultural area. Keven Stobbs, general manager at Barhale, explained that at Fleet Haven and Westmere the pumping stations are in the first line of defence for the low-lying land behind the seawall and both locations provide operational challenges. “We obviously have to work around the elements – not least a significant tidal range,” he said. “To ensure we deliver the works as quickly as possible, we are planning on using some innovative approaches. They will include installing a Portadam system at Fleet Haven Pumping Station and using a specially-designed scaffolding which can be submerged at high tides at Westmere Pumping Station.” Barhale regional director James Haddon sees the company’s selection for both South Holland IDB contracts as an endorsement of its expertise and reputation at a time when water management is a high priority. “Long-term changes to the climate will continue to place a greater burden on water infrastructure,” he said. “Only in the last 18 months have we seen the impact of storms Ciara and Dennis and it is vital that we make sure that we are in the right shape to deal with future challenges. “South Holland IDB is taking steps to improve the resilience of this important agricultural area and we are delighted to have been chosen as the partner to deliver their programme.”
New technology will be used to design Enfield Council’s £6bn Meridian Water development to ensure it delivers the maximum benefits to as many people as possible. Jacobs is partnering with Enfield Council to provide program and master plan leadership, technical design and planning advisory services for the development of a new masterplan for Meridian Water. The company is using geodesign technology to make the development sustainable and ensure there is good access to parks, transport links, schools, healthcare, food and jobs ensuring Meridian Water is a truly transformational scheme for the people of Enfield. They showcased their design software in the ‘Meridian Water – Sustainable and Resilient by Design’ presentation given at the Esri 2021 Geodesign Summit which was hosted online between 9-11 February. Details of the presentation can be found in the Jacobs Newsroom at https://www.jacobs.com/newsroom With cities around the world are facing unprecedented levels of change. The usual drivers – a warming climate, rapid population growth, urbanization, and advances in technology have been exacerbated by coronavirus, exposing social inequality and reinforcing the message of how connected our communities are. It means the plans for Meridian Water must have plans in place to ensure it, and its residents, can meet the challenges of the future, head on. Enfield Council’s Leader Cllr Nesil Caliskan, said: “We have always been clear that Meridian Water is more than just a housing development, it is a pathway to jobs, prosperity and a better future for thousands of Enfield residents. But the scheme needs to be resilient and enable the people who live there to rise to future challenges by being resilient and sustainable for many years to come. “Using this approach will enable us to find innovative solutions to the challenges we face in planning this scheme and ensure we have a wealth of data available before we make critical decisions. It will directly benefit the people of Enfield because we will deliver a world class development for them which will be genuinely transformational for our borough.” The Meridian Water redevelopment project is a major £6 billion, 20-year regeneration program led by Enfield Council, bringing 10,000 homes and 6,000 jobs to the borough. Alongside beautiful homes and world-class public spaces and community facilities, the 200-acre development will have its own brand-new railway station – which is already completed, linking commuters to the region. As well as working on the masterplan, Jacobs is also providing client technical advisory service across several disciplines during the design and delivery of over £150 million of strategic infrastructure works to help unlock the Meridian Water site.

London’s canals have seen in the last forty years a great resurgence, but, at the same time, they have also been used for leisure and alternative living more than their originally intended purpose. The ongoing housing crisis has made many property owners view setting up a home in a floating boat a viable option. Ex-industrial areas are continuously being developed and barges are being overlooked as a viable way to transport away construction waste and bring in materials. Two examples of this situation are two large canal-side development projects that could easily incorporate the waterways into their efforts – Enfield Meridian Water Development and Old Oak Park Royal Development Corporation. As HGVs are causing a vastly disproportionate amount of cyclist road deaths, getting freight off the roads would be safer, would reduce traffic and their environmental impact, with water transport only using around a quarter of the energy of an equivalent road journey. A brief glimmer of hope was seen when Stratford was identified as the site for the 2012 Olympics. The area around the proposed park is riddled with canals and backwaters, perfect for heavy freight. Despite promising noises and the building of a new lock at Three Mills, which opened up a route to processing plants along the Thames Estuary, this option was not engaged with in any meaningful way. The long hoped-for revival of waterways freight never happened and with the privatisation of the canals, it seems even further away. Moreover, the Canal and River Trust (CRT), the charity that now managed England and Wales’s canals, does little to encourage waterborne freight. A concerted EU effort has seen a great resurgence in freight borne on inland waterways in mainland Europe, but unfortunately nothing comparable is happening on this side of the Channel. However, this is not due to a lack of options, as the UK has the infrastructure in place already. It is just a matter of using it.
