Sentinel Rock Lift Station Odor Mitigation Project – This project aims to reduce wastewater-related odors and improve system reliability for our Carefree community. The Liberty team is strengthening key equipment, repairing the force main pipeline, and adding odor-control through iron dosing and chemical injection. Together, these improvements will reduce odor impacts for nearby residents, strengthen operational resilience, and support safer, more consistent wastewater treatment and conveyance.

Strengthening the reliability of our wastewater system
Liberty is proud to provide safe and reliable wastewater service to our customers and communities in Arizona.
The series of capital projects contribute to a more reliable and resilient wastewater system that meets state and federal standards. These projects are imperative to maintaining a system that protects your health, the health of your community, and the environment.
Project spotlight: Carefree Highway Lift Station relocation
As part of the City of Scottsdale’s Carefree Highway roadway widening project, certain underground utilities must be relocated to accommodate the City’s improvements. The existing Carefree Highway Lift Station, which helps move wastewater through the system, is currently located within the planned roadway expansion area and must be relocated.
In addition to relocating the lift station, the Liberty team will make several upgrades to support long-term reliability and keep the wastewater system operating safely and efficiently.
Other projects
Manhole rehabilitation and slip lining – When water from rain or groundwater enters the sewer system through manholes and pipes, it creates unnecessary strain on the system and can even drive up treatment costs. To resolve this issue, the Liberty team is coating manholes with epoxy to extend their service life, installing cured-in-place pipe to seal segments and joints, and lining older clay pipes to prevent leaks and restore structural integrity. This will help reduce the load on our system and keep our operations running efficiently for the long term.
