Achieving more for less

Affinity Water is the largest water-only supplier in the UK, providing over 900 million litres of water each day to a population of 3.5 million. We have been working with Affinity since 2005 managing its asset delivery programme, a relationship which has since evolved to now see us working with the client as one collaborative and integrated team.

The £450 million, five year investment programme covers a broad range of work including overseeing capital investment projects. As a delivery partner, we have to be very aware of the increasingly tough regulations and targets set for Affinity by the Drinking Water Inspectorate and water regulator, Ofwat. There is also a growing emphasis on stakeholder engagement, reducing costs and minimising disruption to customers.

Driving efficiencies

Our role is to help Affinity to reach targets such as the significant efficiencies it was required to make during the replacement of 600 kilometres of its water mains. By carrying out in-depth analysis of the costs of the renewal, and identifying where new target costs and savings could be made, we helped to reduce the unit rate by around 30%.

We worked with main contractors and subcontractors to introduce common systems and processes to save costs and improve productivity. A PMO system was also introduced ensuring continuous visibility of the works to provide valuable real time information.

A healthy approach

A safety leadership team was introduced and tasked with reducing accidents, utility strikes and improving quality. Clear processes have consistently improved quality audit performance from 74% to over 98% compliance.


April 2015 saw us reappointed by Affinity Water as its service provider as they move into AMP6, the upcoming regulatory period for the water industry. Mace will provide programme and project management expertise, design and delivery services, commercial management and planning expertise to ensure successful delivery of Affinity Water’s asset investment portfolio.  Securing the service provider role, allows us to continue the exciting journey to assist Affinity Water to develop their creative and ambitious business plan that sets new standards for the way they will deliver high quality water for its communities over the next five years.
