EBJ Business Achiever of the Week: CH2M HILL, Brown & Caldwell

   Hats off this week to CH2M HILL (Denver, CO) and Brown and Caldwell (Walnut Creek, CA), winners of 2011 Business Achievement awards in the project merit category for the design of the Brightwater Treatment Plant in King County, Washington, the largest membrane bioreactor installation in North America at 39 million gallons per day (mgd). The Brightwater design includes chemically enhanced primary clarification for the treatment of peak wet-weather flows, as well as features in the aeration basin blower system to save costs and energy consumption. The facility produces Class A reclaimed water for irrigation and non-potable use. Biosolids are dewatered and distributed off-site for beneficial use. The Brightwater facilities are fully enclosed and ventilated using a three-stage odor-control system, producing no detectable odor at the property line. A former automobile wrecking yard has been transformed into the facility’s 120-acre park-like setting, incorporating streams, wetlands, trails, and overlook structures. In addition, an environmental education/community center, designed to Leadership in Energy and Environmental Design (LEED) Platinum standards, provides public meeting space, interpretive displays, and teaching and laboratory facilities.   For a full list of EBJ’s 2011 Business Achievement Award winners, please visit www.ebiresearch.com/2011_EBI_Business_Achievement_Awards. EBJ will begin accepting nominations for 2012 Business Achievement Awards in October.
