Reliability Centered Maintenance Program for California Wastewater Plant

State of California

Central Valley, California

A California wastewater plant wanted to build a Reliability Centered Maintenance (RCM) Program, but didn't have adequate budget to perform analysis and implementation at one time. Because of upcoming repair, replace, and rehab work, the plant included RCM as a necessary element in construction projects related.

Topics Covered

Water Quality


Initial: 2 Million USD


General Fund/Existing Public Funds

Project Status

Operational since 2019

Gov Champion

City Engineers

Problem Addressed

A California wastewater plant was experiencing recurring asset failures that put it at risk for potential regulatory violations.

Like facilities across the nation, California water and wastewater facilities have aging infrastructure and assets and lack adequate budgets to tackle the challenges they face.

Recurring asset failures, especially critical assets such as Ultraviolet Disinfection System, were stressing operations staff and bringing the facility concern about potential regulatory violations down the road. They wanted to build stronger systems to trust the reliability of the facility and its treatment of wastewater.

Solutions Used

The facility is using a staged Reliability Centered Maintenance approach to improve the reliability of plant operations 

Reliability Centered Maintenance (RCM) helps facilities extend the life of aging assets, improve the lifecycle costs of new assets, and improve the reliability of operations.

This can help facilities and owners build the breathing room they need to develop long-term asset management solutions built around providing reliable service. At this facility, the budget for comprehensive risk assessment and program development wasn't available, but Pinnacle is flexible in working with facilities and owners, recommending a staged approach to more slowly build reliability into the system during system upgrades.



Improved operations and maintenance management


Longer asset lifespan


Expected reduced lifecycle costs


Better performance tracking from baseline at construction

Something Unique

Employing a staged approach to Reliability Centered Maintenance (RCM) analysis and implementation is not typical, but it worked here. This gave the client the opportunity to experience the benefits of RCM as each stage was completed, building support within the department for this solution.

Who Should Consider

Full plant RCM is recommended because it allows for clearer understanding of how the plant works as a whole. But clients who lack adequate funding or want a demonstration, can benefit from a staged approach.
