India’s water treatment industry is experiencing strong growth, propelled by tighter regulations, ambitious sustainability targets, and a rising demand for wastewater recycling and Zero Liquid Discharge (ZLD) solutions. With expanding industrial requirements and mounting concerns over water pollution, the sector is evolving rapidly to address these pressing challenges.

The Indian Water & Wastewater Treatment Market was valued at $7.3 billion in FY24 and is likely to reach $12.8 billion by FY29, growing at a robust CAGR of 12%, according to Denta Water RHP. This growth is being driven by regulatory mandates, urbanization, and the pressing need for efficient water management. As water scarcity intensifies, industries and municipalities are adopting stringent effluent treatment norms to reduce freshwater consumption.

Government policies and industrial reforms are accelerating the adoption of advanced water treatment technologies, ensuring effective wastewater treatment before discharge. The focus on sustainability – both domestically and internationally – alongside stricter environmental norms, is expected to drive heavy investments in wastewater recycling, treatment, and desalination projects. This opens up strong opportunities for listed water treatment companies.

Pollution: A Critical Concern For India’s Water Resources

Water pollution remains one of India’s biggest challenges. Over 70% of surface water sources are contaminated due to industrial waste, untreated sewage, and agricultural runoff. The Central Pollution Control Board (CPCB) has identified 351 polluted river stretches, with the Yamuna, Ganga, and Godavari among the worst affected.
