Southern Water has named the winners of three packages of work, worth £630M in total, which will see a range of improvements delivered under its £3Bn AMP6 period Business Plan for 2015 to 2020.


CMDP, a joint venture between Costain and MWH, will carry out schemes to maintain and improve Southern Water’s water supply and wastewater treatment works Kent and East Sussex. This work is worth around £200M over the five year period.


GTM, a joint venture between Galliford Try and Imtech, supported by strategic design partner Atkins, has been awarded a contract to deliver similar services in West Sussex, Hampshire and the Isle of Wight.


MGjv, a Morrison Utility Services and Galliford Try joint venture, will deliver Southern Water’s investment to expand and maintain its network of water mains and sewers, totalling more than 53,000km in length. Support will also be provided by strategic design partner AECOM.


Southern Water’s AMP6 Business Plan is expected to support around 6000 jobs across its 94 water supply works, 368 wastewater treatment works and extensive water and wastewater networks. These latest contract awards begin this month and will run to the end of March 2020, each with an option to extend them for a further five years.


The delivery partners will work closely with MWH, which was separately appointed as Southern Water’s strategic solutions partner in August – helping to design and plan the water supplier’s infrastructure projects.


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.”


Southern Water said it will announce which companies will carry out day to day repair and maintenance of its water mains and sewers, as well as its water supply and wastewater treatment works from 2015 to 2020 later this year.
