Water Treatment Chemicals Market size was more than USD 37.1 billion in 2026 and is set to grow at a 3.99% CAGR between 2027 and 2036, reaching USD 54.86 billion by 2036. The industry revenue for 2027 is assessed at USD 38.35 billion.
Increasing freshwater scarcity will drive the water treatment chemicals market as municipalities and industrial operators place greater emphasis on treating available water resources and recovering usable water from wastewater streams. Chemical treatment plays an important role in processes that remove contaminants, control impurities, and condition water for subsequent use or discharge. As water availability becomes a more important operational consideration, treatment facilities require dependable chemical inputs to maintain water quality across municipal systems and industrial processes.
Expansion of water reuse and desalination projects will propel the water treatment chemicals market by increasing the need for specialized chemical solutions throughout advanced water purification processes. Reuse facilities require treatment chemicals to support contaminant removal and conditioning of recovered water, while desalination operations depend on chemical treatments for pretreatment, membrane protection, fouling control, and process efficiency. The growing deployment of these water-supply strategies therefore broadens chemical consumption across increasingly sophisticated treatment infrastructure.
The adoption of AI-enabled water management platforms is strengthening the water treatment chemicals market by improving the ability of operators to monitor treatment conditions and optimize chemical dosing. Data-driven systems can analyze changing water characteristics and operating parameters to support more precise application of treatment chemicals, reducing unnecessary dosing while maintaining required treatment performance. Integration of intelligent monitoring with treatment operations also enables facilities to respond more effectively to variations in water quality and process conditions.
