The capital contractors will work to improve and maintain the company’s vast network of underground water pipes and sewers as well as above ground pumping stations, treatment sites and reservoirs.

Projects will include the monitoring, refurbishment and replacement of trunk mains, some of which date back to the 1800s, and the installation of the latest technology to help detect and pinpoint leaks as the company looks to reduce leakage by a further 15 per cent over the next five years.
The frameworks have been awarded in two lots:
Lot 1 - Non-Infrastructure – Costain, MWH Treatment, Mott MacDonald Bentley, Kier Infrastructure, Glan Agua, Galliford Try, Barhale & Bridges Electrical
Lot 2 - Infrastructure – Kier Infrastructure, Morrison Utility Service, Galliford Try, J Browne Cons, Barhale Ltd & Clancy Docwra
John Bentley, Thames Water’s capital delivery director, said:
“This is a really difficult but exciting time for us and our suppliers as we mark the start of the delivery phase of AMP7. We know we have some tough challenges to get through now and lying further ahead, but we’re all set to work together in providing resilient and reliable clean and waste water services to our 15 million customers across London and the Thames Valley.
“We have ambitious plans for the next five years including a further reduction of leakage, reducing interruptions to water supplies and reducing pollutions, and our suppliers will be key to helping us achieve those goals.”
Last year, Thames Water announced its decision to move away from an alliancing approach and implement an “intelligent client” operating model across its capital delivery function during AMP7.
The model will see the company bring more activities in-house in the key areas of asset management, programme management, project management, technical assurance and commercial management. Work will be delivered through a series of delivery “runways” covering all of the capital programme.
The newly announced frameworks form a part of “Runway 2” which will be used to deliver medium to large programmes and will run until the end of AMP7 with an option to extend them into AMP8.
The procurement process for geographical frameworks which will run in parallel to the Thames-wide frameworks is currently underway.
Thames Water has this week also announced it has extended its Infrastructure Alliance contracts for a further five years. These contracts are responsible for work on the company’s clean water network including finding and fixing leaks and responding to bursts. The alliance partners are KCD (Kier, Clancy Dowcra) and Agility (Morrison Utility Services and J Murphy).
