APWA Project of the Year

WestLand is proud to announce that the South Rillito West Central Interceptor Rehabilitation (SRWC) project was awarded both the American Public Works Association (APWA) Southern Arizona Branch and Arizona Chapter Project of the Year Awards in the Environmental Category ($5 -$25 million). WestLand was a key member of the Construction Manager at Risk (CMAR) team, working under the direction of KE&G Construction and the Pima County Regional Wastewater Reclamation Department to provide engineering services for junction structure design, slip-lining, and extensive flow management plans.

The SRWC project rehabilitated nearly four miles of structurally deficient 48-inch and 54-inch sewer systems along the south side of the Rillito River between Columbus Boulevard and Tucson Boulevard in central Tucson. The project area encompassed densely populated 50-year-old neighborhoods, an elementary school, a popular fitness center, a busy animal shelter and a portion of “The Loop” shared-use trail.  The project utilized an innovative combination of cured in place pipe (CIPP) and slip-lining techniques, rather than excavating and replacing the large-diameter lines.  The CMAR team was able to complete the project three months ahead of schedule, under budget and without major disruptions to the public including zero interruptions to existing services.

This is the first of three major projects that, when completed, will rehabilitate 14 miles of large-diameter sewer pipe and construct a connection across the Rillito River – a $41 million investment that will extend the life of the community’s wastewater facilities by more than 50 years.

The SWRC project set the gold standard for efficiency and cooperation for the remaining projects.
