Kier Integrated Services and Morrison Utility Services have secured places on a £400 million framework with Affinity Water.
The companies have been appointed to the four year framework by the Home Counties and North West London water supplier.
Broken down into three programmes, the framework has a combined value of £100 million per year.
Its three programmes are made up of: Distribution Mains; Developer New Mains and Services (Developer Services); and Design and Installation of Trunk Mains.
Morrison Utility Services has been appointed to the Distribution Mains and Developer Services programmes.
The company will take responsibility for design and build works covering 100 km of mains renewals per year, while also working on more than 600 developer services schemes.
Kier has been chosen for the Trunks Mains programme and will design and install trunk mains to transport water around the Affinity Water network. The contracts will start in January.
The framework makes up the bulk of Affinity Water’s £500m infrastructure investment between 2015 and 2020.
Kier and Morrison Utility Services previously worked together under Anglian Water’s AMP6 programme.
The two firms secured contracts with the water supplier in 2014.
Kier was selected along with Clancy Docwra to deliver Anglian Water’s AMP6 Integrated Metering and Developer Services contract, valued at up to £12m a year.
Kier, Morrison Utility Services and Barhale were chosen for Anglian Water’s Integrated Operational Solutions contract, valued at around £70m over five years.
Meanwhile, Kier has announced “significant revenue growth to £1.7 billion, up 34 per cent,” according to the firm’s full-year results.
The company said that the results for the year ending June 30 this year were underpinned by “a raft of strong facilities management contract wins, worth a total of around £100 million.”
The results also showed that underlying profit from operations of £150 million increased by 44%, including a full year’s contribution from Mouchel.
