The secondary research process involved comprehensive analysis of regulatory databases, industry publications, technical standards, and authoritative infrastructure organizations. Key sources included the US Environmental Protection Agency (EPA), Federal Highway Administration (FHWA), American Society of Civil Engineers (ASCE), American Water Works Association (AWWA), Water Environment Federation (WEF), National Association of Sewer Service Companies (NASSCO), North American Society for Trenchless Technology (NASTT), International Society for Trenchless Technology (ISTT), US Bureau of Transportation Statistics (BTS), Eurostat Infrastructure Database, European Environment Agency (EEA), Organisation for Economic Co-operation and Development (OECD) Infrastructure Statistics, World Bank Infrastructure Data, and national public works associations from key markets. These sources were used to collect pipeline infrastructure condition data, regulatory compliance requirements, technology adoption rates, municipal spending patterns, and market landscape analysis for cured-in-place pipe (CIPP), pipe bursting, slip lining, spray-on pipe lining, and other trenchless rehabilitation technologies.

Additional authoritative sources included ASTM International (F1216, F1743 standards), ISO/TC 138 standards for plastic pipes, US Census Bureau Construction Spending Reports, Environment Canada, UK Environment Agency, German Institute for Standardization (DIN), Japan Sewage Works Agency, and Australian Bureau of Statistics infrastructure datasets.

In order to gather both qualitative and quantitative insights, supply-side and demand-side stakeholders were interviewed during the primary research process. CEOs, VPs of Engineering, heads of R&D, and commercial directors from liner material suppliers, specialist contractors, and trenchless technology makers were examples of supply-side sources. Municipal public works directors, utility managers, civil engineering consultants, procurement leads from water and wastewater authorities, and project managers from oil and gas pipeline operators were examples of demand-side suppliers. In addition to gathering information on pricing tactics, procurement trends, and the mechanics of regulatory compliance, primary research verified technology adoption timetables and validated market segmentation.

Global market valuation was derived through revenue mapping and project volume analysis. The methodology included:

Identification of 50+ key manufacturers and service providers across North America, Europe, Asia-Pacific, and Latin America

Technology mapping across Cured-in-Place Pipe (CIPP), Pipe Bursting, Slip Lining, Spray-on Pipe Lining, and other rehabilitation methods

Material analysis across Polyvinyl Chloride (PVC), Polyethylene (PE), Fiberglass, Epoxy, and other resin systems

Diameter segment analysis across Small Diameter (<6 inches), Medium Diameter (6-24 inches), Large Diameter (>24 inches) pipes

Analysis of reported and modeled annual revenues specific to trenchless rehabilitation portfolios

Coverage of manufacturers and contractors representing 75-80% of global market share in 2024

Extrapolation using bottom-up (project volume × ASP by country/region) and top-down (manufacturer/contractor revenue validation) approaches to derive segment-specific valuations
