India Zero Liquid Discharge Market to Reach USD 2.52 Billion by 2032, Growing at a CAGR of 9.5% During 2026–2032

The India zero liquid discharge market was valued at approximately USD 1.33 billion in 2025 and is projected to grow from USD 1.46 billion in 2026 to USD 2.52 billion by 2032, registering a CAGR of 9.5% during 2026–2032. The market is supported by tightening industrial discharge requirements, groundwater stress, and increasing investments in wastewater recycling and reuse infrastructure across water-intensive industries.

Additionally, regulatory enforcement and the substantial wastewater treatment gap are supporting market expansion. In July 2024, the Central Pollution Control Board issued an SOP for verifying ZLD compliance in distilleries, requiring certified ZLD documentation for ethanol distillation capacity assistance. India generates approximately 72 billion liters of wastewater daily, while only around 28% is treated, increasing the responsibility on industrial facilities to manage wastewater onsite and strengthening demand for advanced ZLD systems.

Furthermore, zero liquid discharge system deployment is increasingly being incorporated at the design stage of semiconductor and solar manufacturing facilities. Manufacturing hubs such as Gujarat and Telangana are witnessing this transition as high-technology facilities require substantial ultrapure water and generate complex wastewater streams. Micron Technology's USD 2.75 billion semiconductor facility in Sanand incorporates advanced water conservation technologies enabling ZLD, while VA Tech WABAG secured a USD 5.34 million integrated ultrapure water, effluent treatment, and ZLD project for a 2 GW solar cell manufacturing facility in Hyderabad.

In parallel, thermal-based ZLD remains the leading technology segment, accounting for approximately 60% share, driven by its suitability for high-TDS industrial effluents generated by textiles, distilleries, chemicals, pulp and paper, and other industries. By capacity, 5+ MLD plants capture approximately 45% share, supported by demand from large-volume effluent generators and common effluent treatment infrastructure. Moreover, the market remains moderately fragmented, with the top five companies collectively accounting for approximately 43% share.
