Multi-use Path Revegetation
In addition to the newly paved Loop pathway - RWRD, Pima County Regional Flood Control District and the Town of Marana are working closely to restore the Loop linear park pathway and amenities. Restoration through this project will include an improved irrigation system, revegetation with native trees, shrubs, and other desert plants along with improved maintenance access.
Project Description
The Pima County Regional Wastewater Reclamation Department (RWRD) and its Design-Build Team, consisting of Borderland Construction, B&F Contracting, and Westland Resources, will soon begin a project to design and build seven miles of new dual force main sewer in Pima County, northwest Tucson/Marana area (see map). A force main is a pressurized sewer pipe that conveys wastewater where gravity sewage flows are not possible. Pumps push the sewage through the force main from lower to higher elevations or across landscapes where deep excavation is not feasible.
RWRD owns and operates the Continental Ranch Regional Pump Station (CRRPS) located on Coachline Boulevard approximately one-half mile east of Silverbell Road, and halfway between Twin Peaks Road and Avra Valley Road. The CRRPS delivers wastewater to the Tres Ríos Water Reclamation Facility (WRF) located on the west side of Interstate 10 near Ina Road, by means of an existing force main routed generally along the west bank of the Santa Cruz River to Cortaro Road, to Silverbell Road, to Ina Road, and then along the south side of Ina Road to the facility.
The addition of the dual-pipe force main between the CRRPS and Tres Ríos WRF will increase sewer conveyance capacity, operational flexibility, and adds redundancy to the existing pump station operations. The new dual force main will follow a similar alignment along the western bank of the Santa Cruz River, but vary as needed to optimize construction and operations.
Design phase services to establish the new force main alignment and footprint started on April 13, 2020 and will take approximately 9-12 months to complete. Construction is slated to begin in early 2021. We expect the new force mains to be complete by late 2022. There may be preconstruction field investigations along the alignment prior to construction.
