Nicholas Street Sewer Extension Phase 1

Hawkins Construction completed the Nicholas Street Sewer Extension for the City of Omaha in response to the EPA’s mandate to comply with the Clean Water Act. Because of aging sewers in the city, raw sewage was flowing into the Missouri River over 50 times a year, causing health and safety concerns. This complex urban sewer separation project consisted of 8,613 linear feet of large-diameter reinforced concrete pipe (RCP); 5,488 linear feet of smaller vitrified clay pipe (VCP); and ductile iron sanitary pipe. Due to the tight urban setting and excavation depth, usually ranging from 15 to 25 feet, continuous sheet pile was required to install the pipe. Also, since the water table in this area is typically 10 feet deep, dewatering of the trenches was required for over 90 percent of the installation.

The project requirements included several milestone dates, which were met by utilizing two highly capable crews. Even with tough conditions and a tight timeframe, Hawkins Construction was able to complete the project over six months ahead of schedule, minimizing impacts to the neighboring community.
