Shaun Stevens Appointed Chair of British Water UK Forum

Shaun Stevens

EPS' UK General Manager Shaun Stevens has taken over as Chair of the British Water UK Forum.

Shaun has also been appointed as a Director of British Water on a two-year term. 

With 25 years experience in the water industry, working in both contracting and consultancy roles, Shaun is an accomplished senior manager, business development lead, project manager and environmental consultant, working with EPS since 2011.

Shaun is a long-standing contributor to British Water, as a member of both the UK Forum (formerly the Municipal Market Group) and the International Forum, as well as being an appointed International Business Mentor and he is also the Chair of the Hampshire Water Hub.

As he begins his term, Shaun knows that there are significant challenges to be faced.

“This is a particularly challenging and exciting time to be stepping up into the role. The pressures of Covid-19 are driving rapid and transformational change in the UK water sector which, combined with Brexit and the transition to AMP7, are putting a much sharper focus on the role of British Water and its work on behalf of the supply chain”

“I would like to pay tribute to the Board of British Water, in particular the out-going UK Forum Chair Steve Webber, for welcoming me so warmly into the fold and for supporting me in my year as Vice-Chair. I’d also like to thank EPS for giving me the opportunity to put myself forward and for the role. I know it’s going to be a rewarding experience and an important step forward in my professional development.”

Nereda and Off-Site Construction at Great Dunmow Makes the Press

Great Dunmow WRC, Essex, UK

An article by EPS' Shaun Stevens and Michael O'Sullivan on the combination of Nereda® technology with off-site construction was featured in a recent edition of the Insitute of Water Magazine.

Great Dunmow is a biological treatment plant with 3 No. reactors, 600m³ each.

EPS provided a DB/DfMA package to the value of £3.4m, which consisted of:

  • layout & hydraulic design
  • design manufacture and installation of storm tank tipping buckets
  • interconnecting pipework system & Nereda® technology for influent buffer
  • Nereda reactors & sludge buffers
  • tertiary treatment
  • instrumentation system
  • access steelwork &
  • process commissioning

EPS provided a full DfMA federated 3D model; minimised site deliveries and installation time.

New Nereda Process Goes Live at Great Dunmow WRC

Great Dunmow 2

The construction of the UK’s second wastewater treatment plant using the Nereda® process reached a major milestone on Friday 22nd June 2018 with the first discharge to river from the new process stream. The plant, located at Anglian Water’s Great Dunmow Water Recycling Centre (WRC) in Essex, provides treatment to a population equivalent of over 10,000 people and discharges treated effluent to the adjacent River Chelmer.

The project has been delivered by Anglian Water’s capital delivery partners in the @One Alliance. At an early stage, space constraints dictated that use of a conventional activated sludge process was not feasible and, following early engagement with EPS and Royal Haskoning DHV, Nereda® was selected as the preferred solution.

Nereda® is an aerobic granular sludge process, originally developed at the University of Delft in Holland and now owned and licensed by Royal HaskoningDHV. The technology is well proven with more than fifty projects worldwide and achieves high standards of nutrient removal on a significantly smaller footprint than conventional processes, whilst also delivering operational cost benefits including energy and chemical savings.

As an existing Nereda® licensee with experience of delivering and operating three Nereda® plants in Ireland, EPS were able to share past learning and apply embedded expertise to support the @One Alliance’s development, design and delivery of the Great Dunmow Project. Collaborative working arrangements and the use of a shared digital design were successful in rapidly formulating a scheme design with the buy-in of Anglian Water’s asset management and operational teams.

EPS has delivered the bulk of the mechanical works on site, including a new packaged inlet works, storm tank cleaning systems, Nereda® process equipment, FuzzyFilter tertiary treatment, pump and blower sets, instrumentation, pipework galleries and access steelwork. The majority of the equipment was facory built and delivered in a modular form to accelerate site assembly times and improve quality and safety standards on the project. Special modifications had to be made to the solution to mitigate flood risk on the site.

Working to a constrained programme, civil works began on site during last summer, with the MEICA element commencing in November 2017. Some flow was diverted to the plant in early May 2018 leading to the process being ready to discharge to river a few weeks later. Commissioning has been assisted by Royal HaskoningDHV experts who will continue to support Anglian Water in the operational phase.

“This project has demonstrated the benefits that early engagement, collaborative working and digital engineering systems can bring to the delivery of complex treatment plants,” says Shaun Stevens, EPS’ Business Development Manager. “In spite of the extreme challenges presented by the site and the programme, the @One Alliance and EPS have been able to meet Anglian Water’s required outcomes using smart thinking and a different way of working. We see this as a template for future projects of this type.”  

@One Alliance Project Delivery Manager, Richard Screaton says, “This has been a hugely exciting project which has brought out the best in our supply chain. It is only through a mature relationship and collaborative approach that we have managed to achieve so much, in so little time and with so many constraints placed upon us. The success of the project is a credit to all involved.”
