In California, a wastewater treatment facility serves a small local community of under 20,000.

95 percent of treated wastewater is reused during the dry season—thus, reliability of the wastewater treatment plant is of utmost importance.

With RCM implementation by PinnacleART experts, total costs have been reduced by 60 percent.

Applying Reliability Centered Principles to a Small Scale Facility

A California wastewater treatment facility serves a small local community of under 20,000, as well as other community service organizations. This wastewater treatment facility is a state-of-the-art membrane bioreactor plant (MBR) that includes fine screening headworks process, full nitrification-denitrification treatment, biosolids drying, chlorine contact disinfection and subsurface effluent disposal fields. The plant was designed to treat a maximum daily flow of 500,000 gallons per day.

During the wet weather season the community reuses approximately 30 percent of its treated wastewater, and during the dry season the recycle water reuse jumps up to 95. This variation is due to California’s lack of rainfall in summer months. Moreover, when dry summer months are coupled with California’s ever-changing drought conditions, reliability of the wastewater treatment plant becomes of the utmost importance to this environmentally sensitive community. To read more, download the full case study.
