ABNA’s Environmental design experience includes planning, preliminary plans, cost estimating, hydraulic modeling, sanitary design, open channels, watershed studies, structural design including design for specialty structures, & construction management. This experience has been applied to several water/wastewater infrastructure systems for entities such as regional sewer districts, state transportation agencies, and the Corps of Engineers. Some of our more complex projects have entailed sewer rehabilitations projects, design of sanitary systems, combined sewer systems, components of waste water treatment plants, providing pump station and interceptor evaluations a well as inflow and infiltration (I/I) investigations. This experience has facilitated ABNA’s position as a leading designer for providing analyses and solutions for a variety of water/wastewater systems across the Midwest.
