India Water and Wastewater Treatment Chemicals Market Size & Outlook

The water & wastewater treatment chemicals industry size in India is valued at USD 2.38 billion in 2025 and is projected to reach USD 2.49 billion in 2026 and USD 3.65 billion by 2032, expanding at a CAGR of 6.6%.

 Growth is supported by rising industrial water consumption, tightening discharge regulations, and increasing adoption of industrial water treatment chemicals across manufacturing, municipal utilities, and process industries to ensure compliance and operational continuity.

Global regulatory alignment continues to accelerate structural demand for advanced treatment systems. The World Health Organization (WHO) and UN-Habitat under SDG 6.3 are strengthening global monitoring of safely treated domestic and industrial wastewater, encouraging expansion of secondary and tertiary treatment infrastructure. This is driving wider deployment of membrane filtration, biological systems, and high-efficiency municipal water treatment chemicals, particularly in regions facing rapid urbanization and wastewater stress.

At the national level, large-scale infrastructure investments are reinforcing long-term consumption of treatment chemicals. According to the Press Information Bureau (PIB), under AMRUT 2.0, approximately 583 sewerage projects worth USD 7–8 billion have been approved to enhance urban wastewater treatment capacity and expand reuse infrastructure. In parallel, industrial clusters are increasing demand for chemical-intensive processes such as coagulation, disinfection, sludge conditioning, and nutrient removal, strengthening uptake of specialty water treatment chemicals.

Additional growth momentum is being created by industrial expansion and water-intensive manufacturing growth. India’s chemical, pharmaceutical, textile, refinery, and food processing sectors continue to expand capacity, increasing demand for process water treatment, boiler feed water conditioning, and effluent treatment systems. Rising water reuse adoption across industrial parks is also improving chemical consumption intensity per unit of water treated, supporting sustained market expansion.

Policy-driven circular water frameworks are further reshaping long-term demand patterns. Uttar Pradesh’s Safe Reuse of Treated Water Policy (2026) targets 50% wastewater reuse by 2030, with progressive movement toward full reuse across agriculture, industry, and urban supply. This structural transition is accelerating investment in high-performance chemical formulations, digital monitoring systems, and advanced treatment technologies, reinforcing long-term growth of the water treatment chemicals industry.

India Water and Wastewater Treatment Chemicals Market Growth Drivers

Escalating Water Stress Driving Chemical Treatment Demand

India's growing industrial water treatment requirements are being driven by intensifying structural water scarcity, which is increasing reliance on water reuse and advanced treatment solutions. According to the Ministry of Jal Shakti, India's annual per capita water availability is estimated at 1,449 cubic metres in 2024, remaining below the 1,700 cubic metre water-stress threshold. The tightening freshwater balance is compelling municipalities and water-intensive industries to expand wastewater recycling, thereby increasing consumption of water treatment chemicals for purification, disinfection, and reuse applications.

The growing pressure on conventional water resources is further strengthening demand for specialty treatment chemicals across industrial sectors. The Central Ground Water Board (CGWB) reports that India's total annual groundwater recharge declined to 446.9 billion cubic metres in 2024, reflecting rising extraction pressure despite ongoing conservation measures. As industries increasingly adopt recycled water to ensure operational continuity and regulatory compliance, investments in chemical dosing, corrosion control, membrane protection, and biological treatment solutions continue to accelerate, supporting long-term growth of the India water and wastewater treatment chemicals market.

Recent Trends

Zero Liquid Discharge Adoption Accelerating Specialty Chemical Demand

The adoption of zero liquid discharge (ZLD) systems is emerging as a major trend across the water and wastewater treatment chemicals market as regulatory oversight on industrial wastewater management continues to intensify. In 2025, the Central Pollution Control Board (CPCB) revised its industrial classification framework, covering 419 industrial sectors under the Red, Orange, Green, White, and newly introduced Blue categories to strengthen pollution control and environmental compliance. The tightening regulatory framework is accelerating investments in ZLD systems, increasing demand for specialty water treatment chemicals including antiscalants, corrosion inhibitors, membrane cleaners, and crystallization additives.

The trend is further supported by stricter wastewater management requirements for high-polluting industries such as chemicals, textiles, pharmaceuticals, distilleries, and tanneries, where ZLD and high-water-recovery technologies are increasingly adopted to meet regulatory obligations. The growing deployment of reverse osmosis, multiple-effect evaporators, crystallizers, and automated dosing systems is strengthening the use of industrial water recycling solutions while creating sustained demand for high-performance treatment chemicals that improve membrane efficiency, minimize scaling, and enhance water recovery rates.

India Water and Wastewater Treatment Chemicals Market Opportunities and Challenges

Raw Material Import Dependency Creating Local Innovation Opportunities

India's continued reliance on imported chemical intermediates remains a key challenge for the market, exposing manufacturers to supply chain disruptions and raw material price volatility. According to UN Comtrade 2024 data, India imported organic chemicals worth approximately USD 25.65 billion, while imports of chemical products and preparations (HS 3823/3824) reached USD 1.61 billion. The dependence on imported feedstocks for specialty formulations, including those used in water treatment, increases production costs and procurement risks for domestic manufacturers of specialty water treatment chemicals and industrial treatment solutions.

The growing focus on sustainable chemistry and domestic manufacturing is creating new opportunities for the market as companies invest in next-generation treatment formulations. In May 2024, Kurita Water Industries established Kurita AquaChemie India Private Limited in Chennai to strengthen the local supply of industrial water treatment chemicals and technical services for India's expanding manufacturing sector. Additionally, in July 2024, Kurita partnered with Solugen to develop carbon-negative, bio-based water treatment chemicals that replace conventional phosphorus-based additives, highlighting the industry's shift toward green water treatment chemicals and sustainable industrial water management solutions.
