West Side Diversion Tunnel Named Outstanding Civil Engineering Project of the Year

Heavy rain that falls in the area serviced by the new West Side Diversion Tunnel is no longer a concern for Davenport Public Works Director Mike Clarke.   Downpours used to overstress the sewer system, causing backups in residential basements and several manholes.   But now flooded basements and sewer overflows are largely a thing of the past.

Called Davenport, Iowa’s most significant long-term development project, the 3.1-mile-long sanitary sewer project serves the dual function of relieving stress on the aging sewer system and opening up nearly 10,000 acres for future development.   The project took a decade of planning and several years to construct, replaced aging sewers and added much needed capacity for Davenport, pop. 102,000. 

Despite unexpected challenges, the $51 million project was completed on schedule and $9 million under budget.  Stanley Consultants provided master planning, design, and construction phase services. 

In addition to the OCEA award, this project has received four other honors.

  • National Honor Award from the American Council of Engineering Companies (ACEC)
  • Grand Conceptor Award from the American Council of Engineering Companies (ACEC) of Iowa
  • 2015 Top Project Award from Water and Wastes Digest Magazine
  • Award of Merit Water/Environment Category in the Engineering News-Record Midwest Best Projects competition
