India's Industrial Water Opportunity Map

India's industrial water and wastewater infrastructure market is projected to grow from USD 2.87 billion in 2024 to USD 4.65 billion by 2030 (Frost & Sullivan) — an 8.3% CAGR driven not by choice but by regulatory enforcement and hydrological constraint. This opportunity map sizes the market across five solution tiers, eight industry verticals and six states, and locates where the returns actually sit: semiconductor-grade ultrapure water, digital and AI water platforms, operations-and-maintenance annuities, and zero-liquid-discharge with resource recovery. It carries decision-grade frameworks — a Policy Risk Matrix, Value Chain Economics, a Five-Forces read and an Investment Heat Map — three named scenarios to 2030, and stakeholder playbooks for investors, technology providers, policymakers and industrial buyers. Twelve chapters, 119 tables, 46 charts, verified company profiles and a full financing analysis, with every market figure attributed to its source.
