Cloacina, LLC
About
Cloacina LLC, headquartered in Arroyo Grande, California, manufactures stainless steel package wastewater treatment plants and is owned and operated by a family of licensed wastewater operators spanning four generations. The company holds Contractors License 1107658 and operates regional divisions including Cloacina South in Texas and Cloacina Pacific. Cloacina's product line is organized around proprietary PAC-series systems: MEMPAC membrane bioreactors for municipal and industrial applications (available in expandable configurations that allow capacity growth), MEMPAC-R rental MBR units for temporary or emergency treatment needs, DRYPAC aerated sludge handling systems, PRIMEPAC primary treatment systems, and HEADPAC-R rental headworks units. Additional offerings include UV disinfection systems, scalping plants for partial-flow treatment, and membrane upgrade services for existing installations. All equipment is constructed in stainless steel rather than carbon steel, reflecting the company's operator-centric design philosophy — the founding family's hands-on plant operations experience informs engineering decisions around maintainability and corrosion resistance. Cloacina serves engineers, developers, wineries, municipalities, and food and beverage facilities, with nationwide shipping capability from its Central Coast manufacturing facility.
