The contractors have been selected for the water company’s sixth asset management period (AMP6), which runs from 2015 to 2020. Both also have options to extend into AMP7 (2020 to 2025).
Costain said that its contract, being undertaken in a joint venture with MWH, was worth £200m. It is the third major contract that Costain has secured from water companies in the AMP6 cycle.
Galliford Try said that it expected £215m of revenue from its contract. It has secured one of two process lots in a joint venture, called GTM, with Imtech and supported by strategic design partner Atkins. The majority of the work on the secured process lot, worth up to £250m to GTM, will focus on water supply and wastewater treatment works.
Galliford Try has also secured both the water and wastewater network lots in a joint venture, called MGjv, with Morrison Utility Services and supported by strategic design partner Aecom. These lots, worth up to £180m to MGjv, involve upgrades to water supply and wastewater pipelines and pumping stations.
Southern Water chief executive Matthew Wright said: “We look forward to working with CMDP, GTM and MGjv, together with MWH, as part of our new Southern Water Partnership to plan and implement innovative ways of improving the water and wastewater services we provide. This, in turn, will make us more efficient and able to provide better value to our customers.”
The newly announced members of the Southern Water Partnership will be delivering improvements across the company’s 94 water supply works, 368 wastewater treatment works and extensive water and wastewater networks under the following ‘packages’ of work:
- CMDP, which sees Costain & MWH working in a joint venture, will deliver a range of schemes to maintain and improve Southern Water’s water supply and wastewater treatment works in the eastern half of its region (Kent & East Sussex)
- GTM, a joint venture between Galliford Try and Imtech, supported by strategic design partner Atkins, has been awarded the contract to deliver maintenance and improvement schemes at water supply and wastewater treatment works in the western half of Southern Water’s area (West Sussex, Hampshire and the Isle of Wight)
- MGjv, which is made up of Morrison Utility Services and Galliford Try working in a joint venture, will deliver Southern Water’s investment to expand and maintain its network of water mains and sewers, totalling more than 53,000 kilometres in length. Support will also be provided by strategic design partner Aecom.
These delivery partners will work closely with MWH, which was separately appointed as Southern Water’s strategic solutions partner last month. MWH is helping to design and plan the company’s infrastructure projects, for example, upgrades to water supply and wastewater treatment works, as well as other improvement work.
Later this year Southern Water will announce which companies will be supporting the day-to-day repair and maintenance of its network of water mains and sewers, as well as its water supply and wastewater treatment works, during 2015 to 2020.
Southern Water provides water and wastewater services to 4.5 million people across the southeast of England.
