Nicholas Street Phase 1 Project Selected as ACEC Grand Award Winner

The Omaha CSO Nicholas Street Phase I (10th Street to 16th Street) Project was recently selected as ACEC (American Council of Engineering Companies) Nebraska’s Excellence in Engineering Grand Award Winner.  Submitted to ACEC for an award by Lamp, Rynearson & Associates, the project was designed and constructed to provide combined sewer overflow relief to portions of North Omaha in accordance with Omaha’s CSO Long Term Control Plan, approved by the Environmental Protection Agency.  The design consisted of hydrodynamic hydraulic and hydrologic modeling, sewer route evaluation, capacity evaluation, storm sewer, sanitary sewer, paving plans and profiles, and geotechnical and environmental evaluations.  To provide the required separation and capacity, construction of three 108-inch storm sewers and one 24-inch clay sanitary sewer in a combined, 50-foot-wide trench began in March of 2012, along with local sewer separation and corridor reconstruction of 11th Street, a primary industrial route.

The project was completed under the combined design and construction administration budget of $1.7 million and under the construction cost budget of $16.2 million.  Scheduled for completion by December 1, 2013, the construction was completed four months ahead of schedule.  The first in a series of sewer separation projects in this basin, the Nicholas Street Sewer Separation was a success, meeting the needs of the CSO Program and the City of Omaha.
