South Rillito Interceptor

The RWRD's South Rillito Interceptor (SRI) is another major interceptor with additional capacity that runs along the south side of the Rillito River, parallel to the NRI. The SRI rehabilitation project begins in an area near Columbus Boulevard and runs west for 3.9 mile along the south bank of the Rillito River to the intersection of Roger Road and Tucson Blvd.

Construction will be completed in three phases. Please note that while these construction plans are number 1 to 3 from west to east, actual construct of the SRI will begin in the east and move westward.
