Core offering

Northwest Pipe Company manufactures and sells engineered steel water pipe (12″ to 156″ diameters), proprietary Permalok steel casing pipe with interlocking joints for trenchless installation, the patented InfraShield geohazard-resistant joint system, HDPE-lined reinforced concrete pipe and manhole systems (Perfect Pipe, Perfect Lined Manhole), bar-wrapped concrete cylinder pipe, and a full line of precast concrete products and packaged water/wastewater systems. Products are custom-engineered to project specifications for municipal water transmission, sanitary sewer rehabilitation, trenchless construction, stormwater management, and industrial applications, with sales structured around engineering specifications and project-based quoting.

Product overview

Northwest Pipe Company (operating as NWPX Infrastructure) provides a comprehensive portfolio of water infrastructure products and systems. The core offering spans engineered steel water pipe products including the proprietary Permalok steel casing pipe line with interlocking press-fit joints, and the InfraShield geohazard-resistant joint system for seismic applications. The company also manufactures reinforced concrete pipe (RCP) and precast concrete products including manholes, box culverts, vaults, and custom structures. A significant product line includes lined sanitary sewer solutions featuring Perfect Pipe (HDPE-lined RCP), Perfect Lined Manhole Systems, Hybrid PVC Manhole Systems for rehabilitation, and Composite FRP Rehab Panels, all designed to protect against microbiologically induced corrosion (MIC). Packaged water and wastewater systems include factory-assembled MeterVault, BackFlo, GreaseTrooper, OilTrooper, DeconTank, and PumpTrooper products. The portfolio is rounded out with bar-wrapped concrete cylinder pipe for water transmission. These products serve water transmission, stormwater management, sanitary sewer, trenchless construction, industrial, and rehabilitation applications across municipal, commercial, and industrial sectors.

Products and services

• Engineered Steel Water Pipe Custom-manufactured spiralweld and straight-seam steel water pipe in diameters from 12″ to 156″, manufactured per AWWA Manual M11 standards for water transmission, wastewater, and industrial applications. Targeted at municipal water utilities, contractors, and engineering firms for large-diameter pipeline projects.
• InfraShield Joint System Patented geohazard-resistant steel pipe (GRSP) solution with fully welded, gasketless joint design that absorbs ground deformation from seismic events, differential settlement, landslides, and liquefaction hazards. Targeted at municipalities and engineers specifying critical water pipelines in active seismic or fault zones, with Buy America compliance for federally funded projects.
• Permalok Steel Casing Pipe Proprietary interlocking steel casing pipe with press-fit machined joints that eliminate field butt-welding for trenchless applications including microtunneling, pipe jacking, auger boring, and pipe ramming. Targeted at contractors and municipalities on trenchless pipe installation projects, with over 4,000,000 feet installed in 25 years.
• Permalok Radial Bending Joint (RBJ) Patent-pending steel pipe joint enabling curved radius installations in microtunneling applications, allowing pipe to be installed along intentionally curved alignments while maintaining structural integrity. Targeted at trenchless contractors and wastewater authorities on curved microtunneling projects.
• Permalok HDD Pipe Direct push system for Horizontal Directional Drilling (HDD) operations that eliminates pipe string-out and field welding, reducing project footprint and construction costs. Targeted at trenchless contractors on HDD crossings; awarded NASTT Innovative Product of the Year.
• Concrete Jacking Pipe Reinforced concrete pipe (RCP) designed for microtunneling and pipe jacking operations, manufactured with self-consolidating concrete for smooth finish and tight tolerances to withstand compressive jacking forces. Targeted at trenchless contractors on sewer and utility installations requiring concrete jacking.
• Perfect Pipe HDPE-lined reinforced concrete pipe combining concrete durability with corrosion-resistant synthetic liner for 100+ year design life in municipal wastewater systems, with weld-free internal joint connector protecting against microbiologically induced corrosion (MIC). Targeted at municipal wastewater authorities for sanitary sewer and wastewater conveyance projects.
• Perfect Lined Manhole System Precast concrete manhole with integrated plastic liner protecting against microbiologically induced corrosion (MIC), available in sizes from 48″ to 120″ diameter with monolithically cast base and channel system. Targeted at municipal wastewater authorities for sanitary sewer manhole installations and rehabilitation projects.
• Hybrid PVC Manhole Rehab System Corrosion-resistant manhole rehabilitation solution combining FRP-lined concrete base and lid with PVC riser section, with 10-year warranty and 100-year design life and installation achievable in under one day. Targeted at municipalities and contractors rehabilitating corroded sanitary sewer manholes.
• Composite FRP Rehab Panels PP honeycomb core panels with FRP outer layer for rehabilitating large wastewater structures, using 3D scanning for custom panel layout, mechanically fastened with high-strength grout fill and sealed seams. Targeted at municipalities rehabilitating large wastewater structures including siphons and pump stations.
• RCP & Precast Concrete Products Full line of reinforced concrete pipe and precast products including RCP, manholes, box culverts, vaults, power and communication vaults, catch basins, and custom structures, manufactured at NPCA-certified facilities. Targeted at municipalities, DOTs, and contractors for stormwater drainage, utility, and structural applications.
• Bar-Wrapped Concrete Cylinder Pipe Steel cylinder pipe lined with cement mortar and reinforced with helically wrapped steel bar per AWWA C303 for water transmission and distribution in municipal, industrial, and agricultural systems, with over 10,000 miles installed since 1970. Targeted at municipal water utilities for water transmission and distribution mains.
• Packaged Water & Wastewater Systems Factory-assembled, pre-plumbed water and wastewater systems including water meter vaults, backflow prevention systems, grease interceptors, oil-water separators, decontamination tanks, and pump lift stations for reduced field installation time. Targeted at municipalities, commercial developments, and industrial facilities requiring factory-engineered packaged systems.
• Power & Communication Vaults PacifiCorp-approved precast concrete vaults for underground electrical and communications infrastructure, including certified padvaults for Rocky Mountain Power and Pacific Power service territories, with NEC and CEC compliance. Targeted at electrical utilities, telecom providers, and dry utility infrastructure providers requiring spec-approved vaults.
