AECOM announced today that a joint venture in which it participates has been awarded a US$24-million contract to upgrade the Woodhouse Mill Wastewater Treatment Works for Yorkshire Water in the United Kingdom.

The AECOM and Galliford Try joint venture team will provide technical and management services to refurbish pumping station facilities, existing inlet screw pumping station, new inlet works and other facilities as well as design several new components for the Yorkshire system.

“We look forward to continuing our relationship with Yorkshire Water as it improves its infrastructure for the area’s residents,” said John M. Dionisio, AECOM chairman and chief executive officer.

The contract is part of Yorkshire Water’s Fifth Asset Management Plan capital-delivery framework. The program is designed to ensure that the treated water discharged back into the environment meets the standards of the revised European Freshwater Fish Directive, which will go into effect during 2015.
