What National Plant Services, Inc. does

National Plant Services, Inc. provides environmental infrastructure maintenance services specializing in sewer condition assessment, trenchless rehabilitation, and pipeline inspection. Founded in 1981 and headquartered in Long Beach, California, with a Bay Area service yard in Hayward, the company serves municipalities, utilities, industrial companies, and engineering firms across the western United States. Its service portfolio spans 16 distinct offerings organized into Sewer Services (inspection and rehabilitation), Sediment Services (vacuum cleaning and sludge dewatering), and Water Services (water main inspection and leak detection), with the proprietary Carylon 3D Multi-Sensor Inspection System collecting CCTV, sonar, and laser data in a single pass for pipes 10 inches to 18 feet in diameter.

The company's technical foundation combines trenchless rehabilitation methods (Cured-in-Place-Pipe lining, chemical grouting, spincasting, lateral lining) with multi-sensor inspection platforms that capture H2S corrosion, ovality, and debris quantification to accuracy of +/-0.001% of pipe diameter. NPS operates a specialized fleet including high-velocity jetters (up to 165 gpm at 2,500 psi), vacuum vehicles (3,200-7,500 cfm), CCTV, sonar, and laser profilers. All field work is NASSCO PACP-coded, and emergency response capabilities are demonstrated through deployments at the 2018 Montecito mudslides and a 2022 LA County 8-million-gallon spill response. The company has completed over 200,000 linear feet of laser inspections since 2014.

NPS operates as a wholly-owned subsidiary of Carylon Corporation, a network of 14 best-in-class environmental services companies founded in 1949. Revenue is generated through project-based contracts secured via competitive bidding, RFPs, and direct contractor engagement with pricing per linear foot, per joint, per hour, or per project scope. The company provides detailed upfront bids to municipal customers and guarantees all work performed. National reach is available through the Carylon network, while direct field operations concentrate on customers from Denver to the west coast. Revenue is not publicly disclosed.

Products and services

• Acoustic Inspection of Pipelines Cost-effective acoustic inspection service that detects blockages in sanitary sewer systems caused by roots, fats, oils, or grease buildup before overflows occur. Uses transmitter/receiver technology to analyze tone degradation through pipe air gap and rate blockage severity on a 0-10 scale.
• Digital TV Inspection CCTV inspection service using latest equipment and NASSCO PACP coding standards to locate trouble spots such as cracked tiles, offset joints, and blockages without excavation. Explosion-proof cameras available for hazardous environments.
• Infiltration Control Combination digital television inspection and sewer joint sealing service that provides guaranteed solution to excessive infiltration without costly excavation, traffic disruption, or bypass pumping of sewage.
• Spincasting Centrifugally cast cementitious pipe rehabilitation system for corrugated metal pipes, culverts, concrete pipes, catch basins, and storm water structures using fiber-reinforced cementitious mixture applied via spinning nozzle without excavation.
• Lateral Service Line Inspection and Sealing Comprehensive lateral service line inspection and rehabilitation including CCTV inspection, cleaning, root cutting, MTH lining (up to 80 feet without cleanout), lateral connection repair using CIPP connection liner, and chemical grouting sealing.
• Manhole Rehabilitation Structural rehabilitation and protective coatings using epoxy (100% solids, zero-VOC) or cementitious formulations for cost-effective permanent seal against corrosion, infiltration, and exfiltration. Includes manhole chimney sealing services.
• Multi-Sensor Pipeline Inspection Multi-sensor inspection (MSI) collecting data from multiple sensors on one robotic platform in one pass. Includes CCTV, sonar, and laser technologies for pipelines 10 inches to 18 feet in diameter.
• No-Dig CIPP Repairs Cured-in-Place-Pipe (CIPP) lining repair using trenchless technology for pipe repair, rehabilitation, or replacement without excavation. Uses resin-impregnated, polyurethane-coated felt tubing installed via pull-in, inflate and cure methods for pipes 6 inches to 3 feet in diameter.
• Sewer Cleaning Comprehensive sewer cleaning including high velocity jetting (up to 165 gpm at 2,500 psi), power bucketing, and root removal with EPA-approved herbicidal treatment to inhibit root regrowth.
