About Enviro Infra Engineers Limited

Enviro Infra Engineers Limited (EIEL), incorporated in 2009, is a leading player in India’s water and wastewater management industry. Founded under the vision of Late Shri R.K. Jain and now steered by the second generation of promoters, the company has built its reputation on sustainable and innovative engineering solutions. Headquartered in New Delhi, EIEL provides end-to-end services for sewage treatment plants (STPs), sewerage schemes, common effluent treatment plants (CETPs), water treatment plants (WTPs), and water supply schemes (WSSPs).

Over the years, the company has executed projects with a cumulative water treatment capacity of more than 784 MLD across 58 sites pan-India. Its solutions address the pressing challenges of water scarcity and pollution, enabling industries and municipalities to reuse treated water, generate power from waste, and comply with stringent environmental regulations.

A major milestone in its journey came in FY 2024–25, when EIEL launched its initial public offering (IPO), raising Rs 650 crore. The issue was subscribed 90 times overall, with qualified institutional buyers oversubscribing by 157 times. Shares were listed on BSE and NSE on November 29, 2024. 

The company operates both independently and through joint ventures, and its projects are funded by central schemes like AMRUT, Jal Jeevan Mission (JJM), and Namami Gange, alongside state government and multilateral support. In line with circular economy principles, EIEL has begun integrating renewable energy and compressed biogas units into several plants, thereby expanding beyond treatment into “waste to value” initiatives.
