Press Release

AECOM announced today that a joint venture in which it participates has been awarded a place on a US$532-million, five-year framework contract for Yorkshire Water.

The AECOM and Galliford Try joint venture team, known as ETM, has secured the design and build assignments for a new water treatment facility for the U.K. client at Acomb Landing in North Yorkshire as well as the upgrade of the existing wastewater treatment facilities at Calder Vale in Wakefield, West Yorkshire.

These assignments are part of Yorkshire Water’s “Large Schemes” infrastructure-improvement program. Work on the program will be split between four entities – each guaranteed a base workload over a five-year period.

AECOM’s fee as part of the ETM joint venture, on three framework streams, is expected to be approximately US$209 million during the five-year timeframe.

“AECOM is excited to be a key part of this vital program as we evolve our relationship with Yorkshire Water,” said John M. Dionisio, AECOM president and chief executive officer.
