Skanska has said that it will lead the construction of a groundwater treatment plant in Hanford, in Washington State in the US for CH2M HILL, a company involved in the energy, chemicals and environmental sectors.

The contract amounts to $50m, approximately SEK360m, and will be included in order bookings for the second quarter. The project is to receive support from the US government stimulus package, the American Recovery and Reinvestment Act.

The project comprises an approximately 5,000sqm operations and processing building, 200 West Groundwater Treatment System, for groundwater treatment. The finished plant, with a capacity of 7.6 cubic meters per minute, will treat groundwater containing radioactive and biological contaminants.

After processing, the groundwater will be of drinking water standard in order to prevent leakage of contaminants into the nearby Columbia River.

Work on the site will commence in the summer and will be completed in 2011. The construction management assignment will be conducted by Skanska USA Building’s office in Seattle, Washington.

The new plant will be constructed with the aim of meeting the demands for Gold-level certification in accordance with the international LEED environmental system.
