North Lewis Boulevard Water Main 1st Street To 31st

Location: Sioux City, Iowa   Client: City of Sioux City, Iowa
Services: Design, Construction Observation and Administration   Expertise: Water Resources

Project Overview

The existing water main along N. Lewis Blvd. has failed several times and repairs are difficult because the existing main is under pavement along the heavily traveled corridor. A larger main was also needed to improve distribution flows and connectivity. Key challenges on the project included maintaining water service to existing customers during construction, project coordination with the Iowa DOT, impacts from several Leaking Underground Storage Tanks (LUST), and traffic control along the heavily traveled corridor.

Working with the City, McClure developed a construction phasing and connection plan to allow for minimal water service disruption to customers during construction. McClure staff conducted individual meetings with affected businesses in order to understand impacts to their water service and access drives, and incorporated these concerns into the design. McClure worked closely with the local Iowa DOT office during design to get their input on design decisions before the final plans were developed. McClure also evaluated different pipe sizes and recommended a 16” main, rather than the planned 24”, saving on material costs while still improving system connectivity and flows.

Project Highlights

  • 10,500 LF of 16” water main
  • High level of public and business involvement
  • Coordination with Iowa DOT, Iowa DNR, Railroads, and Utility Companies
