Edmonton-based Stantec has acquired Roth Hill, a 30-person civil engineering firm based in Bellevue, Wash.

The acquisition will allow Stantec to expand its water/wastewater and municipal service capabilities in the Pacific Northwest.

“Roth Hill and its talented staff bring client-focused expertise in infrastructure design that expands our growing reach in a region where we see continued opportunity,” says Stantec president and CEO, Bob Gomes.

Roth Hill holds an extensive project portfolio designing systems for every facet of collection, distribution and/or treatment of water and wastewater. Recent projects include design of a half-mile trenchless pipe installation for Covington, Wash., design and studies to replace 29,000 feet of state highway water mains for Lynwood, Wash., and the conceptual planning and design for the municipal sewer system supporting Carnation, Wash.
