Wastewater

Our engineers have significant experience in the planning, design and construction management of municipal wastewater systems. We have designed treatment plants, many miles of sewer line, and dozens of pump stations.

In the design of wastewater treatment plants, our team continuously looks for opportunities to reduce the operations and maintenance costs (and efforts) that can be so high with modern wastewater plants. Of special note are the aerated lagoons in Amity, Willamina, and Junction City. Through careful planning and design, HBH was able to design aeration systems that save the cities thousands of dollars per year in electrical costs and literally millions in construction costs.
