North Rillito Interceptor - Completed
Pima County Regional Wastewater Reclamation Department (RWRD) and their contractor, B&F Contracting, Inc. completed work on the North Rillito Interceptor Sewer Rehabilitation Project (NRI) in April of 2017.
The NRI is a large diameter pipeline, approximately 10 miles long, that transports wastewater from the City's far east side in the Woodland Road and Bear Canyon Road area, along the north bank of the Tanque Verde Creek and Rillito River, to the Ina Road Wastewater Treatment Facility -- which serves a major portion of northern and eastern Tucson. Although there were no immediate plans to increase the NRI's capacity due to limited density growth, the RWRD must comply with U.S. Environmental Protection Agency guidelines relating to wastewater system capacity, management, operations and maintenance, and minimizing the number of sewer overflows.
Rehabilitation of the NRI employed a Cured-In-Place (CIPP) Lining Process that was completed in six phases, (as seen in map above) but not in order*.
*For more information about the CIPP Lining Process, please see CIPP Process/FAQS.
