The global trenchless pipe rehabilitation market size was valued at USD 5.50 billion in 2025 and is projected to grow from USD 5.74 billion in 2026 to USD 8.03 billion by 2034, registering a CAGR of 4.30% during the forecast period (2026–2034). North America dominated the trenchless pipe rehabilitation market with a share of 38.3% in 2025.
Trenchless pipe rehabilitation is a method of repairing, renewing, or restoring existing underground pipelines with minimal excavation or without extensive open-cut construction. It includes technologies such as cured-in-place pipe (CIPP), pipe bursting, sliplining, spray-in-place pipe, and other rehabilitation techniques used to restore water, wastewater, sewer, gas, and industrial pipelines. Trenchless pipe rehabilitation is commonly associated with SIC Code 1623 (Water, Sewer, Pipeline, and Communications and Power Line Construction) and HSN Code 3917 (Tubes, pipes and hoses and fittings thereof, of plastics).
The trenchless pipe rehabilitation market demand is driven by the aging of underground pipeline infrastructure, the need to reduce excavation-related disruption, and investments in water and wastewater infrastructure modernization. Municipalities, utilities, and infrastructure operators focus on extending pipeline service life, reducing project completion time, and minimizing impacts on roads, buildinge, contributing to the trenchless pipe rehabilitation market growth.

Shift Toward UV-Cured and Low-Disruption Lining Systems
UV-cured CIPP systems are gaining adoption as utilities seek faster rehabilitation with shorter pipeline service interruptions. UV curing provides controlled liner installation and can reduce curing-related preparation and operational requirements compared with conventional thermal curing. EPA-supported demonstrations have validated UV-cured CIPP for wastewater main rehabilitation, including installation with limited surface disruption.
Adoption of Robotic Inspection and Precision Rehabilitation
Utilities are increasingly integrating robotic inspection, CCTV, and digital condition-assessment systems to improve the identification and prioritization of pipeline defects. EPA-supported programs show that CCTV and other inspection technologies can provide detailed defect information for selecting rehabilitation requirements and prioritizing repair activities. Robotic platforms also enable remote inspection of sewer interiors, supporting more precise rehabilitation planning without extensive excavation.
Supply chain disruptions are expected to have a moderate impact on the trenchless pipe rehabilitation market share, given its exposure to fluctuations in resin systems, fiberglass reinforcement materials, polyethylene and PVC materials, liners, curing equipment, specialized machinery, construction inputs, and transportation costs. The market is expected to experience a K-shaped recovery, as established trenchless rehabilitation contractors and technology providers with diversified supplier networks, established procurement relationships, and higher project volumes can stabilize project execution faster, while smaller contractors and emerging providers remain more exposed to material shortages, longer lead times, and higher procurement costs. The market is expected to grow at a CAGR of 4.30%, but prolonged supply chain constraints could approximately lower this by 1.0 percentage point, resulting in short-term growth of around 3.30%. As supply conditions normalize through improved availability of rehabilitation materials, stabilized resin and polymer pricing, improved equipment supply, and replenished inventories, the trenchless pipe rehabilitation market growth is expected to gradually return to approximately 4.30%.
The trenchless pipe rehabilitation market forecasts investment and funding directed toward trenchless rehabilitation technologies, CIPP and UV-curing systems, pipeline rehabilitation contractors, specialized rehabilitation equipment, and expansion of water and wastewater infrastructure rehabilitation capabilities.
In January 2026, the City of Sioux Falls allocated USD 1.3 million for its Water Pipe Trenchless Rehabilitation project to clean and structurally reline water-main segments identified as trenchless construction candidates.
Increasing Leakage and Infiltration Across Sewer Networks and Infrastructure Maintenance Requirements Drives Market
Aging sewer networks with cracks, defective joints, and damaged connections create recurring requirements for controlling groundwater and stormwater infiltration. EPA identifies leakage and infiltration in existing water infrastructure as a major contributor to inflow and infiltration in sanitary sewer systems and associated treatment-system burdens. Municipal rehabilitation programs therefore create continued requirements for CIPP, pipe relining, and other trenchless solutions.
Aging wastewater and sewer infrastructure requires continuous inspection, maintenance, rehabilitation, and renewal to preserve network reliability and extend pipeline service life. Municipal utilities are prioritizing rehabilitation of deteriorated pipelines to address structural defects and maintain consistent wastewater collection performance. The need to maintain existing underground infrastructure creates recurring requirements for CIPP, pipe relining, sewer rehabilitation, and other trenchless renewal solutions.
Complex Bypass Arrangements and High Upfront Costs for Specialized Trenchless Equipment Restain Market Expansion
Continuous wastewater flow can require temporary bypass pumping before rehabilitation work begins, particularly on active sewer networks. The additional planning and temporary-flow management can increase project complexity and extend preparation requirements. These conditions can make trenchless rehabilitation less straightforward for high-flow municipal pipelines.
Specialized UV curing systems, robotic inspection equipment, lining machinery, and rehabilitation rigs require significant capital investment from contractors. Smaller service providers may face difficulty achieving sufficient equipment utilization across project locations. This can limit the number of contractors capable of undertaking technically demanding rehabilitation projects.
Expansion of Municipal Programs for Large-Scale Pipeline Renewal and Development of Smart Inspection Platforms Offer Growth Opportunities
Water infrastructure contractors and pipe-rehabilitation technology providers can expand into potable-water relining, where existing mains can be renewed without extensive surface excavation. Suppliers with certified liner systems and water-main rehabilitation capabilities can develop specialized municipal service offerings. The opportunity extends the application base beyond conventional sewer rehabilitation.
Inspection technology companies can combine CCTV, robotic inspection, defect classification, and digital asset records into integrated condition-assessment platforms. Such systems can create recurring software, inspection, and data-management revenue streams for technology providers and engineering firms. The opportunity is particularly relevant to municipalities managing large underground utility networks.
The cured-in-place pipe (CIPP) segment accounted for a share of 48.6% in 2025, supported by its broad applicability across wastewater, sewer, and other underground pipeline rehabilitation projects.
