Project Description:
The North Willow Farms Neighborhood is a progressive, mature community that was experiencing sewer backups.  A preliminary sanitary sewer evaluation indicated several key project goals:

  • The replacement of approximately 900 lineal feet of 8" and 1,600 lineal feet of 10" vitrified clay pipe (VCP) sanitary sewer.
  • The replacement of 21 lateral reconnections.
  • The replacement or rehabilitation of 11 manhole structures.


During the planning phase of this project, residents of this area revealed concerns about removal of large hardwood trees, fencing, and mature landscaping in the existing utility easements.  Further field surveys revealed additional concerns related to cable, electric and telephone lines located within the same utility easement, as well as a large diameter storm sewer located directly over portions of the existing sanitary sewers.

Based on these complex factors, pipe bursting was used to:

  • Simultaneously remove the existing pipe and install new sanitary sewer pipe and lateral connections.
  • Reduce inflow and infiltration.
  • Satisfy residents by limiting the removal of fences, landscaping, and large trees.
  • Avoid the need for additional easement and minimize the impact on other utilities, which ultimately lowered the environmental impact.
  • Realize a substantial cost savings over a more traditional open-cut construction method.
