Costain has announced that it has been instructed to undertake two major water contract extensions.

Firstly, Costain, as part of the Costain, Galliford Try and Atkins joint venture, has been instructed to undertake £200 million worth of work by United Utilities to upgrade and extend Sandon Dock sewage treatment works in Liverpool.

The project is part of the Asset Management Programme 5 (AMP5) with United Utilities and will be progressed through the existing process alliance framework.

The scheme involves extending the current treatment works into the adjacent dock along with major upgrade works to the existing plant all of which will improve the quality of the final effluent in line with discharge consents set by the Environment Agency.

Furthermore, Costain has announced a further extension to its AMP5 contract with Severn Trent Water worth around £45 million.

Working in partnership with Severn Trent and other non-infrastructure contractors, a programme of major schemes to a value of £187 million has been agreed and will include the provision of wastewater schemes for Costain to design and build.

Commenting on the contract awards, Andrew Wyllie, Chief Executive of Costain, said: "We are delighted to have secured these two contracts, which demonstrate the UK water industry’s continued investment in infrastructure, and help us build on our market leading position in the water sector."
