India Wastewater Treatment Market is Expected to Register a 6.10% CAGR Through 2030

Rapid Urbanization & Population Growth and Water Scarcity & the Growing Need for Water Reuse are likely to propel the market during the forecast period.

According to TechSci Research report, “India Wastewater Treatment Market – By Region, Competition, Forecast and Opportunities, 2020-2030F”, India Wastewater Treatment Market was valued at USD 6.67 Billion in 2024 and is expected to reach USD 9.60 Billion by 2030 with a CAGR of 6.10% during the forecast period.

India’s rapid urbanization and population growth have significantly increased the demand for wastewater treatment solutions. With over 1.4 billion people and a rapidly urbanizing population, the generation of wastewater from residential, commercial, and industrial activities is growing at an unprecedented rate. Urban centers, which host more than 35% of the population, are under pressure to manage the large volumes of untreated wastewater generated daily.

Inadequate sewage infrastructure in many cities further exacerbates the issue, leading to the contamination of natural water bodies and groundwater reserves. Urbanization has also led to the expansion of megacities, which require sophisticated wastewater treatment systems to handle large volumes of sewage. Government initiatives such as the Atal Mission for Rejuvenation and Urban Transformation (AMRUT) aim to provide urban centers with the necessary infrastructure, including sewage treatment plants (STPs) and proper drainage systems, to address these challenges.

The increasing awareness among citizens regarding environmental conservation and health hazards posed by untreated wastewater has further encouraged investments in wastewater treatment. This trend drives demand for advanced technologies like membrane bioreactors (MBR) and decentralized treatment systems in urban areas, positioning wastewater treatment as a critical priority in India’s urban development agenda.

Based on Process, The Secondary treatment held the largest market share in 2024.  Secondary treatment dominates the Indian wastewater treatment market due to its effectiveness in removing organic pollutants, its adaptability to various wastewater sources, and its compliance with regulatory requirements. This treatment stage focuses on biological processes, utilizing microorganisms to break down organic matter, making it an essential step for municipal and industrial wastewater management.

India generates vast volumes of domestic sewage and industrial effluents, both of which contain high levels of organic contaminants. Secondary treatment methods, such as activated sludge processes, sequencing batch reactors (SBRs), and moving bed biofilm reactors (MBBRs), are particularly well-suited for handling this type of waste. These methods efficiently reduce biochemical oxygen demand(BOD) and chemical oxygen demand (COD), ensuring treated water meets the discharge standards set by the Central Pollution Control Board (CPCB).

Cost-effectiveness also plays a significant role in its dominance. Secondary treatment systems are more affordable to implement and operate compared to advanced tertiary systems, making them the preferred choice for municipalities and industries with budget constraints. Moreover, these systems are scalable, catering to both large centralized plants and smaller decentralized setups.

Government initiatives such as the Namami Gange Program and AMRUT emphasize the development of sewage treatment plants (STPs) with robust secondary treatment processes to address urban sewage challenges. Industrial sectors also rely on secondary treatment in their effluent treatment plants (ETPs) to meet environmental compliance requirements.

Given its efficiency, cost-effectiveness, and ability to meet regulatory standards, secondary treatment remains the backbone of wastewater treatment infrastructure in India, ensuring broad applicability across various sectors.

Based on region, North India is emerging as the fastest-growing region in the India wastewater treatment market due to a combination of factors, including rapid urbanization, industrial expansion, and increasing government focus on water conservation and environmental sustainability.

One of the key drivers is the significant urban growth in states like Uttar Pradesh, Haryana, Punjab, and Delhi, which has led to a sharp increase in wastewater generation. As the population continues to rise in these urban centers, there is a pressing need for effective wastewater management to address the escalating demand for clean water and to prevent environmental degradation. Many cities in North India are struggling with aging sewage systems, which often fail to handle the rising volumes of wastewater, further creating an urgent need for modern treatment infrastructure.

North India has a high concentration of industries such as textiles, chemicals, food processing, and paper, all of which generate substantial amounts of waste water. As industrial activities expand, there is a growing demand for advanced wastewater treatment technologies, such as effluent treatment plants (ETPs) and zero-liquid discharge (ZLD) systems, to ensure compliance with stringent environmental regulations.

Government initiatives also play a critical role in driving growth in the region. The Ganga Action Plan and Namami Gange Program, both focused on the rejuvenation of the Ganges River, have accelerated investments in wastewater treatment facilities in states like Uttar Pradesh, Uttarakhand, and Bihar, all part of the river basin. These projects have prompted both public and private sector stakeholders to invest heavily in the construction of sewage treatment plants(STPs) and related infrastructure. Moreover, state governments are actively implementing policies to encourage water recycling and wastewater reuse, which further boosts the demand for treatment solutions.
