Global market valuation was derived through contract value mapping and treatment capacity analysis. The methodology included:
Identification of 50+ key service providers across North America, Europe, Asia-Pacific, Latin America, and Middle East & Africa
Service mapping across chemical treatment (coagulants, flocculants, pH adjusters), equipment supply (filtration, disinfection, biological reactors), and operational services (O&M, consulting, monitoring)
Analysis of reported and modeled annual revenues specific to wastewater treatment service portfolios
Coverage of service providers representing 75-80% of global market share in 2024
Extrapolation using bottom-up (treatment capacity Ă— service cost by country/region) and top-down (service provider revenue validation) approaches to derive segment-specific valuations
Validation against municipal wastewater treatment plant (WWTP) investment databases and industrial effluent treatment project pipelines
