UNITED SITE SERVICES OF CALIFORNIA INC

United Site Services of California Inc. specializes in the deployment, maintenance, and servicing of temporary sanitation and hygiene infrastructure for federal operations. Their core capabilities include the provision and management of portable toilets, shower trailers, restroom units, and septic tank pumping services in remote and high-traffic environments. The contractor demonstrates technical proficiency in logistics coordination for mobile sanitation systems, compliance with environmental and health standards for temporary facilities, and rapid response deployment in field conditions. Their expertise extends to vault toilet servicing, waste containment, and sanitation cycle management in sensitive natural and military settings, ensuring operational continuity where permanent infrastructure is unavailable or impractical. The contractor maintains a consistent presence with the Department of Defense, delivering critical sanitation support for training sites, field operations, and remote installations. They also serve the Department of Agriculture with sanitation services at national forest locations, including high-use recreational areas and field research sites. A single engagement with the Department of Health and Human Services involved contract closeout related to emergency relief services, indicating capacity to support transient public health initiatives. Their primary industry focus is in NAICS 562991—Septic Tank and Related Services—where they operate as a specialized provider of mobile sanitation solutions for federal land and mission-critical operations. They are not engaged in general waste hauling but rather in the controlled, regulated servicing of temporary sanitation systems in environmentally sensitive or logistically constrained areas. The entity is structured as a 2L (small business) with no government certifications on record. While headquartered in Westborough, MA, their operational footprint is defined by federal project locations, primarily across western U.S. national forests and military installations. Their market positioning is that of a nimble, mission-focused contractor delivering essential sanitation infrastructure where reliability and regulatory compliance are non-negotiable.
