SW Ventilation and Capacity Improvements Project

Environmental Services is preparing for construction on a project that will upgrade the capacity of the Southwest Parallel interceptor sewer system along SW Taylors Ferry Road and SW Virginia Avenue to accommodate future peak flows. This project will install about a 1000 feet of new 24 inch concrete pipe on SW Taylors Ferry and 800 feet of new 48 inch concrete pipe on SW Virginia. Crews will also construct a permanent odor control facility in response to past odor complaints.

Project Schedule

The project may begin as soon as February 2015 and will take about a year to complete.

Construction Method

The pipe installation on SW Virginia and Taylors Ferry will be done using both open trench excavation and cured in place pipe replacement methods. Go to the construction methods webpage for more information.
