The Omaha Country Club Sewer Separation Project included a watershed of approximately 156 acres in the Country Club area of Omaha. The watershed is fully developed with single-family homes on quarter-acre lots served by a combined sewer system. The design included the reuse of the existing combined system as the sanitary sewer and installation of a storm sewer adjacent to the existing combined sewer. In total, the project involved approximately 17,000 feet of storm pipe.
As with many sewer separation projects, neighborhood disruption was a major concern. Our team began by addressing this concern with the public through a comprehensive public involvement and interaction plan. Team members met with homeowners associations and individual residents living in the area to discuss the project’s overall goals, gain insight regarding residents’ concerns, and test design considerations.
The new alignment was designed to reduce the impact on the many mature trees located in the neighborhood. Our company provided a tree planting plan for tree replacement and included rigorous requirements for tree trimming and root pruning during the construction process. Green infrastructure was designed to not only improve water quality, but also as an educational means to show the community how green infrastructure can be incorporated into an establish neighborhood seamlessly.
Trenchless installation techniques, specifically pilot tube microtunneling, were used to reduce disruption in the neighborhood and reduce the impact on adjacent utilities and trees. Pilot tube installation was used for both 24-inch and 30-inch storm sewer installation.
