Liberty works hard to maintain and upgrade operational treatment systems to ensure redundancy and improve resiliency, so that we can continue to treat wastewater that meets Class A+ water quality. Our ultimate goal is to provide uninterrupted service, meet or exceed all effluent standards, and be prepared to handle higher flows as needed.

Strengthening the Reliability of Our Wastewater System

The series of capital projects listed and explained below collectively contribute to a more reliable and resilient wastewater system that meets state and federal standards. While the individual descriptions may be technical in nature, these projects are imperative to maintaining a system that protects your health, the health of your community, and the environment. A quality wastewater system is one that operates without interruption or failure and these improvements are steps to fortify that type of wastewater system for you.

Sewer Smoke Tests

Redundant Bar Screen. This will increase resiliency, reduce down time, and ultimately be more efficient and lower costs for repair and replacement.

Supervisory Control and Data Acquisition (SCADA) and lift station telemetry upgrades will improve the overall operation of the treatment facility and lift stations delivering real time data. This monitoring equipment will improve response time should an issue or emergency occur, keeping your service uninterrupted.

Decant Wet Well Pump. This upgrade helps prevent a sewer overflow at the facility. Health, safety and environmental impacts are mitigated with this improvement. Potential for customer backups are also significantly reduced.

Disc Filter 1 & 2 filter replacement and actuator valve replacement. The disk filters are the last treatment process prior to chlorination and then recharge/re-use. This improvement contributes to the process being categorized as a “Class A” effluent, which is the highest possible standard.

Re-use pump replacement. The pump replacement reduces the need for domestic water and allows re-use water in plant operations, resulting in cost savings and improving sustainability.

Re-use pump variable frequency drive replacements. This improvement brings equipment up to current standards and improves efficiency and redundancy for better and more resilient operation.

Redundant digester blower. This provides a secondary option to ensure plant operation can continue with the loss of one blower which would impact the treatment process, ultimately providing better resiliency.

Redundant sludge pump replacement. Redundant pumps increase resiliency and lower the chance of interrupted plant operation which could result in higher costs and emergencies.

16” Disc filter & 24” Mixed liquor valve repairs. The disc filters allow isolation of clarifiers and continued operation should an issue occur to one of the clarifiers. This investment improves consistent plant operation and reduces down time.

Chemical Polymer Skids. Will reduce and save the amount of chemicals we use as part of the dewatering process. The dewatering process removes water from the solids thereby reducing the water weight of the end product that goes to the landfill, reducing cost.

Effluent Pump Replacement. Effluent is pumped from our wet well post treatment and send treated effluent to our recharge basins. The water discharged to the recharge basins then have the opportunity to percolate back into the water table to recharge the water aquifer.

On April 27-29, 2021, Liberty smoke tested the Gold Canyon, AZ wastewater system to help maintain system integrity. Conducting these tests allows Liberty to be proactive and continue to provide reliable wastewater service so customers don’t have to worry about potential sewer blockages, leakage or overflow.
