United Utilities

Improving infrastructure

United Utilities (UU) is one of the largest water and sewerage companies in the UK and between 2010 and 2015 they will have invested more than £3bn to improve their infrastructure. To deliver this programme, meet regulatory deadlines and achieve service outcomes requires significant support.

UU approached their supply chain to engage suitable partners that could operate within an incentivised alliance model to deliver that investment programme. Mouchel formed a design and construct joint venture with contractors Kier, Murphy and Interserve (KMI+), providing detailed design, Construction Design and Management coordination, construction support and commissioning services. The KMI+ joint venture was tasked with responsibility for delivering £420m of improvements to water and wastewater assets.

We took outline solutions and, in collaboration with our construction partners, developed detailed designs, many involving large underground structures connected to existing infrastructure. Technical skills, experience, ingenuity and hard work were essential to successfully deliver outputs while a shared commitment to see the project through from desktop to construction drove our designers.

Collaboration within the joint venture and across the wider Process Alliance underpinned the successful performance of KMI+ and we actively contributed to technical forums to share best practice across all delivery partners.

We also used our wider asset management capability to support more efficient solutions to complex sewerage overflow schemes. We focused relentlessly on achieving safe, constructable designs and ensuring that all regulatory deadlines were met so when challenges arose, particularly during construction, the team pulled together, safely and responsibly, to deliver the assets UU needed – on time and on budget.


‘Thank you for all your efforts to achieve yesterday’s regulation date, I realise the last three months have been both challenging and demanding but yesterday the consent was met, once again many thanks.’
