The Country Club Sewer Separation Project includes a watershed of approximately 141 acres in the Country Club area of Omaha, Neb. The watershed is fully developed single family homes on quarter-acre lots served by a combined sewer system. The current design includes 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 there is approximately 17,000 feet of storm pipe. At four locations, the storm sewer will be installed using pilot tube microtunneling to reduce disruption to the surface, trees and existing utilities. Pilot tube microtunneling is being used where the depth of the sewer is extremely deep.

As with many sewer separation projects, neighborhood disruption is a major concern. The first step of addressing this concern was the development of a comprehensive public involvement and interaction plan. Team members have met with homeowners associations, local business groups and individuals throughout the project area to discuss the project's overall goals, gain insight regarding residents' concerns and explain design considerations.
The new alignment was designed to reduce the impact on trees, because of the presence of many mature trees in the neighborhood. Burns & McDonnell is working with the Planning Department to develop a tree-planting specification to be used on the Country Club project and throughout the CSO program.
Extensive utility coordination was part of the project. The team coordinated with the Metropolitan Utilities District (MUD) for gas and water relocation, because approximately 8,000 feet of water line relocation and over 21,000 feet of gas line relocation are part of the project. MUD also used this project to update existing gas infrastructure within the neighborhood to minimize overall disruption.
