Project story

Affinity Water is the single largest water-only supplier in the UK. The firm provides over 900 million litres of water, to a population of 3.5 million every single day. Our relationship with the company stretches back to 2005, when we managed its asset delivery programme. Today, this has evolved to a stage where Affinity Water's staff and our own function form one collaborative and integrated team.

The £450m five year investment programme covers a vast range of work, including close supervision of capital investment projects. As a delivery partner, the stringent regulations and targets set by water regulator, Ofwat, and the Drinking Water Inspectorate are in the forefront of our mind. There is also a growing emphasis on stakeholder engagement, reducing costs and minimising disruption to customers – a specialist area for our world class team.

Points of note

Driving efficiencies

As service provider, our mission is to help Affinity Water significantly beat its targets. This includes enabling major efficiencies required during replacement of 600 kilometres of its water mains. Via in depth analysis of renewal costs, while also identifying where new target costs and savings could be made, we helped to shrink the unit rate by almost a third.

In line with our vision to boost productivity and reduce costs, we teamed up with our contractors to introduce streamlined systems and processes. A Project Management Office (PMO) system was also introduced to ensure continuous visibility of the works, offering real time information that was of massive value.

A healthy approach

With health and safety a key facet of our company, we introduced a safety leadership team tasked with reducing accidents, utility strikes and improving quality.
