United Utilities Signs Landmark Agreement For £3 Billion Haweswater Aqueduct Resilience ProgrammeWith an estimated construction cost of circa £3 billion the programme will be delivered by Cascade Infrastructure, a consortium of partners within which bring a strong track record of delivering similar tunnelling schemes in Europe.
Cascade Infrastructure Ltd. consists of a consortium of STRABAG and Equitix – the consortium was named by the water company as the preferred bidder to deliver the Haweswater Aqueduct Resilience Programme in January 2025.
The original 110km pipeline - which is approaching its 70th birthday - was a major feat of engineering when it was originally built. It uses gravity to carry 570 million litres of water every day to customers and businesses across Cumbria, Lancashire and Greater Manchester.
As part of the programme to upgrade and improve the region's strategic water network, this new contract paves the way for one of the largest water infrastructure programmes across the UK, creating hundreds of jobs in the region.
The programme is the first in the water sector to be delivered through a Direct Procurement for Customers model to provide best value for customers. It covers the design, construction, maintenance and financing of the scheme.
Chris Taylor-Dawson, Senior Director, Major Projects and Markets at Ofwat described the project as a huge development for the North West, and the first programme of its kind for the sector approved by Ofwat - marking a huge step forward for the water industry as a whole. “Safeguarding water resilience for generations to come is vital and HARP sets a new standard for innovation and collaboration in the sector,” he added.
Construction will get underway in 2026 and will see six tunnel sections replaced with most of the work happening below ground using the latest tunnelling techniques.
As well as securing supplies for millions of customers, the project will bring a range of economic benefits to the region. Around 1200 people will be employed at the construction peak with an apprentice recruitment programme to help build and secure skills for the future.
Louise Beardmore, Chief Executive at United Utilities, said:
"Making the North West stronger, greener and healthier is at the heart of everything we do. Today marks a significant step to ensure we have the right infrastructure to provide a resilient water supply to communities right across the region for decades to come and, at the same time, creating hundreds of great quality jobs and delivering on the commitments and promises we have set out."
Mayor of Greater Manchester, Andy Burnham, commented:
"The Haweswater Aqueduct has served our region well for decades. This landmark investment ensures it will continue to do so for generations to come. It's not just about securing the water supplies we need for our city region to grow - it's also about creating jobs, building skills, and delivering long-term value for our communities."
Water Minister, Emma Hardy said the Government was rebuilding the water network from the ground up through one of the largest infrastructure projects ever seen in Britain.
“In a new era of partnership between government and industry, we are upgrading pipes, tackling sewage spills and safeguarding water security so communities can once again take pride in their rivers, lakes and seas. Investments in projects like the Haweswater Aqueduct will be essential in this effort to secure clean water for future generations." the Minister added.
Cascade Infrastructure Ltd. was first incorporated as a private company with its registered office in England and Wales at Companies House on 15th May 2025.

Scottish Water Nears Completion Of Million Pound Upgrade To Dollar Wwtw In ClackmannanshireThe Devon Way site in Dollar plays a crucial role in treating waste water, handling up to 1500 cubic metres per day. However, after around 30 years, the equipment was nearing the end of its serviceable life and needed to be upgraded.
The first phase required a giant 300-tonne crane to be brought to the site to install temporary treatment machinery to used during the upgrade while the investment work was carried out.
Ten months on, the crane and other heavy machinery is now needed to demobilise the site and a special track will again be laid to protect the road surface along the single track road which provides access to the site. Devon Way will be closed between the A91 west of Dollar and Walton Crescent from Wednesday 13 August to Monday 18 August 2025.
Scottish Water says it is investing record amounts – more than £2 billion over the past 10 years - to address the challenges of ageing assets, increasing demand and climate change.
The Dollar Waste Water Treatment Works project is being delivered by WGM Engineering.

United Utilities Submits Planning Application For First Phase Of £350 Million Amp8 Investment At Davyhulme WwtwDavyhulme wastewater treatment works is set to undergo an initial investment of around £350 million over the next five years to ensure it meets the needs of a growing population and higher environmental standards that will improve water quality in the Manchester Ship Canal.
Situated next to the M60 at Barton Bridge, the site, which first opened in 1894, is one of the biggest wastewater treatment works in the UK. The works drains the entire western side of Manchester, from Chadderton in the north to Bramhall in the south.
A planning application for the first phase of works will see a new building created that will house the latest technology to reduce the amounts of phosphorus in the treated wastewater that is returned to environment. Further improvements in the coming years, will also see reductions to Biochemical Oxygen Demand (BOD).
The work will include the decommissioning and demolition of old assets with a phased approach being taken to the projects on site to ensure that it can continue to operate 24 hours a day.
The site’s bioresources power generation centre is also set to be expanded and modernised as part of the plans. United Utilities has recently joined forces with leading Cambridge-based climate tech firm Levidian to demonstrate the opportunity for biogas produced from wastewater to create hydrogen and super-material graphene at the Bioresources centre at the works.
All the planned development over the next ten years will take place on the current footprint of the site.
Davyhulme was the birthplace of the modern wastewater treatment process that is now in use all around the world. This process was discovered in 1913 by two engineers, Edward Arden and W.T. Lockett who were conducting research for the Manchester Corporation Rivers Department.
Andrew Cunliffe, Wastewater Business Lead for Greater Manchester at United Utilities, said:
“Many people won’t realise the significance of Davyhulme and the part it has played in pioneering modern sewerage techniques. This huge investment over the next ten years will ensure we continue to meet the demands of the city’s growing population whilst improving water quality in the Manchester Ship Canal.”
All phases are subject to any necessary planning permissions being secured.
The works at Davyhulme are being delivered through United Utilities new Enterprise delivery model which brings together seven design and construction partners, plus United Utilities, into one integrated team.

Northumbrian Water Progresses Work On Multi-Million Pound Project To Protect Environment And River Water QualityThe water company is investing £8 million in sewer network upgrades that will protect the environment in a County Durham village. Northumbrian Water is carrying out two projects in Pelton, near Chester-le-Street, that will reduce the frequency of spills from local storm overflows, protecting and improving water quality in the Chester Burn and Cong Burn, as well as watercourses downstream.
The first piece of work will see upgrades to the network around Pelton Community Primary School and is being timed with the school holidays, to minimise disruption.
As well as new sewer pipes being installed, additional underground stormwater storage will be constructed, further reducing the chances of combined sewage and rainwater overfilling the network during periods of heavy rainfall.
This will be followed in the autumn by the start of work on land south of The Wynd, which will see similar upgrades carried out, running through to late summer 2026.
The work, which is being carried out by Northumbrian Water’s partner, Avove, will reduce spills from two storm overflows by more than 65%, to an average of less than ten per year. Storm overflows act as relief valves in combined sewer networks – those that carry both sewage and rainwater – protecting homes and businesses from flooding at times of heavy rainfall.
Christopher Bond, Project Manager at Northumbrian Water, said:
“This investment will benefit the environment around Pelton, by significantly reducing spills from the sewer network to the Chester Burn and Cong Burn. We know that this work will be very visible in and around Pelton over the coming year, so we are working to ensure customers feel informed early and remain updated for the duration of the project.
“Our investment here in Pelton is part of a wider £1.7billion environmental programme across the coming five years, which will see us working to reduce spills from 239 storm overflows, with more to come in the following years.”
Colin Butler, Framework Director at Avove, commented:
“This is a significant project, which will help to reduce spills in the local network, utilising our infrastructure and engineering expertise to achieve the project’s objectives in a timely manner. Its delivery in Pelton not only demonstrates our agility and commitment to working with the local community but marks the beginning of a strong and collaborative partnership with Northumbrian Water.”
Northumbrian Water has also recently completed a £925,000 project to reduce sewer spills and protect the environment in Bishop Auckland, County Durham. The work involved separating parts of the sewer network from the drains that carry surface water, in order to reduce the number of spills from a nearby storm overflow (SO).
The investment will help protect and improve water quality in the Coal Burn, as well as the River Wear, downstream, by reducing spills from that SO by more than 80%, to a maximum of ten a year on average.
The work started in January and has been carried out by Northumbrian Water’s partner, Esh-Stantec.

Thames Water Removes 120 Tonne Fatberg From Oxford Sewer In Complex Two Week OperationPhoto: workers entering large trunk sewer
Every year Thames Water clears 75,000 blockages from their sewer network, at a cost of £18 million. This year to date Thames Water has cleared 35,178 blockages including:
Multiple teams joined forces to tackle the 120-tonne fatberg, stretching over one kilometre through an Oxford trunk sewer. The complex operation took two weeks to complete, involving the removal of congealed fat, oil, grease, and wipes from the pipe located 20 metres underground.
Due to the pipe’s size and depth underground, high gas levels elevated by the fatberg, and the need to maintain Oxford’s wastewater flow, the operation required careful planning with safety as a top priority. This included securing special permits, safely venting the built-up gases before entry and taking advantage of the dry weather conditions to ensure a safe and controlled operation.

Northumbrian Water Launches Preliminary Market Engagement For £240 Million Bran Sands Long Sea Outfall ProjectThe objective of the project is to reduce nitrogen loadings in the Teesmouth and Cleveland Coast Special Protection Area (SPA) by 1st April 2030. This will be achieved by removing the Bran Sands discharge from the River Tees and discharging directly to the North Sea to improve dispersion and dilution.
A Long Sea Outfall for Bran Sands was supported and approved by Ofwat in the regulator’s final determination of the water company’s PR24 business plan. The Levelling Up and Regeneration Act (2023) requires a Technically Achievable Limit of Total Nitrogen of 10mg/l at 'designated STWs' that serve a population equivalent of more than 2,000 people by 1 April 2030 and are within the Nutrient Neutrality area.
To deliver this, the driver was included in the Water Industry National Environment Programme (WINEP) under the Habitats Directive for Nutrient Neutrality.
The project indicatively consists of three works packages:
Types of work under the packages, which may be tendered and awarded individually or in combination, could include:
Northumbrian Water says it welcomes interest from all suitable contractors and suppliers - it is mandatory for any interested suppliers to register on the new Central Digital Platform
At this stage, the water company expects to receive individual entity responses. Once the procurement strategy has been defined, Northumbrian Water is aware that delivery approaches may involve responses from JVs, consortium etc.
The aims of the market engagement activity are as follows:
The Market Engagement Process consists of:
Interested suppliers are required to provide the following information when they submit an expression of interest
Northumbrian Water will review questionnaire responses and select the most suitable suppliers to attend the engagement session. Preference will be given to suppliers with a recent demonstrable track record of delivering long length large-diameter outfall pipeline projects (or part of) of this nature
The water company will hold an in-person workshop / round table session with all invited participants - Northumbrian Water expects to invite c15. The date will be confirmed to shortlisted suppliers once known
Once Northumbrian Water has completed the market engagement, it will then develop a procurement strategy to deliver the project. If this results in an open market competition, any material shared during the engagement process will be included within the tender documents.
Expressions of interest to complete the questionnaire must be sent to via e-mail before the deadline of 12pm on Wednesday 20 August 2025 to
This e-mail address is being protected from spambots. You need JavaScript enabled to view it
. Once the expression of interest window has closed, a link to the questionnaire will be sent to the email address provided by interested suppliers on 21 August 2025. Deadline for completing and submitting the questionnaire is 5pm on Thursday 4 September 2025.
Suppliers selected for further engagement may be invited to an in-person workshop on Tuesday 16th September - further details will be provided following receipt of questionnaires.
Northumbrian Water’s current estimated publication date of a formal tender notice is 2 March 2026. Current estimated start and end contract dates are 31 October 2026 to 31 March 2030

Northumbrian Water Engages Market On Delivery Of £200M Outfall Pipeline Into North SeaNorthumbrian Water has commenced market engagement on the delivery of its Bran Sands Long Sea Outfall, valued at £200M (£240M with VAT).
The ambitious Bran Sands Long Sea Outfall project represents an effort to tackle nutrient pollution in the Teesmouth and Cleveland Coast Special Protection Area (SPA).
Scheduled for completion by April 2030, the scheme is designed to reduce nitrogen loadings by redirecting the Bran Sands treatment works discharge from the River Tees directly into the North Sea. This strategic move promises enhanced dispersion and dilution of nitrogen, supporting compliance with stringent environmental regulations and safeguarding critical marine and estuarine ecosystems.
The outfall was part of Northumbrian Water’s PR24 business plan, which has been approved by Ofwat. It responds directly to the Levelling Up and Regeneration Act (2023), which mandates a technically achievable total nitrogen limit of 10mg/l at designated sewage treatment works serving populations exceeding 2,000 within nutrient-sensitive areas by 2030.
The utility wrote in its PR24 business plan: “The current preference is to build a long sea outfall from our Bran Sands treatment works. This would mean that instead of treated wastewater entering the Tees estuary from Bran Sands, this would now be discharged further out to sea. This treated wastewater is clean and safe for the environment, but still contains nutrients which could cause algae to grow, affecting ecosystems in the Tees estuary. This would not be a problem in the sea, where there would be a lower concentration of nutrients.”
The Bran Sands project is not merely an environmental imperative but also a sizeable engineering challenge.
Currently, the project is planned to unfold in three primary works packages:
The flexibility in procurement – allowing for packages to be tendered individually or as combined contracts – aims to attract a broad range of contractors with specialised expertise.
The scope of work spans the full gamut of civil and marine engineering disciplines. Early contractor involvement is anticipated, a strategy that underscores the project’s complexity and the need for collaborative innovation. Crucial phases include environmental, geotechnical and geophysical surveys both onshore and offshore to inform route alignment and construction methods. While tunnelling options remain under consideration, the deployment of large-diameter polyethylene pipes with concrete ballast for dredged outfall installation and the construction of marine diffuser structures are confirmed highlights.
Given the project’s scale and environmental sensitivity, Northumbrian Water’s market engagement is methodical and intention-driven. The utility aims first to gauge supplier appetite and capacity to deliver such technically demanding schemes. This engagement includes a comprehensive contractor questionnaire, focusing on capabilities, relevant project experience and value addition, ensuring only capable firms progress to the workshop phase. Preference will be given to entities with recent, demonstrable success in delivering long-length, large-diameter outfall pipelines.
The engagement process will culminate in an in-person workshop or round table involving approximately 15 shortlisted participants. This forum will serve as a platform for dialogue on procurement strategies, including how best to package and advertise the work to maximise value and market interest. Northumbrian Water intends to balance exclusive use of established framework partners with opportunities for open competition.
The envisaged contract timeline stretches from October 2026 through March 2030, indicating a phased delivery approach that aligns with regulatory deadlines.
The integration of sophisticated pumping stations and headworks, coupled with the offshore marine construction, positions this project as a landmark in environmental infrastructure within the region.
Beyond its direct environmental benefits, the Bran Sands Long Sea Outfall project promises substantial economic stimulus through procurement and contract awards. It will engage suppliers across civil, mechanical, electrical and marine specialties, potentially fostering joint ventures and consortia collaborations reflective of the multifaceted skill sets required.
