Liverpool Wastewater Treatment Works (WwTW) had problems with the existing, second stage treatment Baff plant blocking up, which led to premature discharges from the works to the River Mersey. A more robust treatment process was required and it was decided that a sequencing batch reactor (SBR) would be built on two levels within Wellington Dock adjacent to the existing works.

GCA JV, a joint venture between Galliford Try, Costain and Atkins, was chosen by United Utilities (UU) to carry out the upgrade of Liverpool WwTW.

UU recognised that to successfully deliver this complex project, a different approach to 'design and build' was required and a ‘One Team One Aim’ initiative was developed. The team was a special partnership of client, contractor and supply chain, working together to ensure the successful design and build of the new works.

All the team were located at the Liverpool site to ensure close collaboration, ownership of the problems and establish a commitment that the team would ‘fix’ Liverpool together. A successful tool for the team was using BIM, which was relatively new in the water industry at the start of the project (2013), but was recognised by the team to be invaluable in ensuring the success of this and future projects in AMP6. They therefore pioneered its use, ensuring the Liverpool project was at the forefront of BIM technology, setting the standards for AMP6.

Following the successful performance of the Liverpool team, UU intend to adopt the collaborative one team ethos to spread the ‘Liverpool magic’ across their upcoming AMP6 major projects.

  • Atkins has created a vision for riverside communities along the River Thames and future use of the waterway with the development of the Thames Strategy for the area in South West London.

    The strategy provides a long term vision and basis for a more holistic approach to the many complex and interrelated issues relating to planning, management and use of the river - issues which require the involvement and commitment of the public, private and voluntary sectors, as well as the local communities, in active partnerships.

    We looked at existing landmarks, historic buildings and landscapes, conservation areas, areas of archaeological and nature conservation interest, as well as public access, recreation and use of the river for sustainable transport.

    Community participation was central to our work and involved the enthusiastic and proactive help and support of numerous local groups and individuals.

  • Atkins delivered an integrated solution to the UK’s largest river restoration project. It is the first of its kind in England to consider restoration on a catchment scale and will act as a national pilot. We provided specialist services including aquatic ecology, geomorphology as well as river restoration design and implementation.

    The River Wensum Restoration Strategy was developed by Natural England, the Environment Agency and the Water Management Alliance. The strategy identifies factors affecting the natural functioning of the channel and the need to bring the river back to a favourable ecological condition.

    Atkins was tasked to implement this strategy and conduct feasibility studies for the 70km river catchment area in Norfolk.

  • Atkins, working with Arup, has been appointed to work with Severn Trent Water Ltd. as part of their clean water strategic grid team. A key part of the grid is the Elan Valley Aqueduct, which is 120 kilometers long and provides water to Severn Trent's customers in Birmingham. Completed in 1906 and now in continual operation for over 100 years, increasing water demands of the city mean the infrastructure is beginning to show its age. 

    Using expertise from our multidisciplinary teams, we established options for the proactive maintenance and replacement of several sections of the Elan Valley Aqueduct (EVA). The objective of the work is to achieve Severn Trent Water’s aspiration for an asset fit for the 22nd Century.  

    Using our extensive water and tunnelling experience, we developed the outline design for the selected schemes, provided planning support and environmental guidance and assisted the client in compiling tender documentation for a design and build contract. The package of 3 schemes covers 4.2 kilometres of 3 metre diameter tunnel, with a capital cost of around £70million.

    This was undertaken as part of a 10 year Engineering Consultancy Framework under which we assist Severn Trent Water in prioritising assets for investment and promoting the best TOTEX solution in achieving the best outcomes for STW and their customers.

  • A joint venture between Atkins and Arup has been appointed for a consultancy contract to deliver a range of design and engineering services for BMB; the joint venture between BAM Nuttall, Morgan Sindall and Balfour Beatty, who have been appointed by Tideway to deliver the West section of London’s new ‘super sewer’, the Thames Tideway Tunnel. 

    Valued at £416 million the six kilometre ‘West’ section of the 25km Thames Tideway Tunnel will run from Acton in West London to Wandsworth in South West London incorporating seven separate work sites along the route. Works will include design, construction, commissioning and maintenance following construction completion. 

    The new tunnel will be the biggest infrastructure project ever undertaken by the UK water industry. 

    The completion is scheduled for 2022.
