Costain appointed to Thames Water AMP6 programme

Costain, one of the UK's leading tier one engineering solutions providers, is pleased to announce that it has been appointed by Thames Water to its 2015 - 2020 investment programme ('AMP6' - Asset Management Period number six), in a contract worth approximately £450m to Costain.

Costain has been appointed to an initial two-year Early Contractor Involvement ['ECI'] contract and will then agree a five-year contract to deliver the AMP6 capital programme from 2015 to 2020. The contract may then be extended for a further five years from 2020 to 2025, as part of AMP7.

In joint venture with Veolia and Atkins, Costain will deliver a significant proportion of Thames Water's programme of essential upgrades to water and wastewater networks and treatment facilities across the capital. The investment in the programme by Thames Water is £2.5 billion in total, and will be one of the largest current asset management contracts in Europe.

Andrew Wyllie, Chief Executive of Costain, commented:

"We are delighted to have been selected by Thames Water to deliver this major AMP6 contract.

"The award is a consequence of our ability to work collaboratively, deliver sustainable innovative solutions to major infrastructure needs, and provide value for money. It also further reinforces Costain's position as one of the leading UK engineering service providers in the water sector."
