India is facing a major challenge in managing water and wastewater as urbanisation, population growth, and industrial expansion continue at a fast pace. To meet this challenge, the government is investing heavily in water infrastructure — especially in Engineering, Procurement, and Construction (EPC) projects for sewage treatment plants (STPs), water supply systems, and waste recycling.
While big infrastructure companies take on multi-sector projects, there are a few focused and emerging listed companies that specialise in water EPC. These companies are quietly building order books and earning government contracts — making them strong candidates for multibagger returns in the next few years.
Enviro Infra Engineers is a rising name in the water infrastructure segment. The company focuses on designing and building sewage and water treatment plants for state and municipal governments. In recent quarters, it has won several large orders for both new plant construction and long-term operations and maintenance contracts.
Its strength lies in its project execution capabilities and ability to win repeat orders. With a growing presence in multiple states, Enviro Infra is emerging as a reliable smallcap EPC company in the water sector.
EMS is another specialized water infrastructure company that works on STPs, WTPs, drainage systems, and water recycling. It has completed dozens of projects across northern and central India and has built strong relationships with government bodies.
The company has a healthy balance sheet, strong margins, and steady growth in revenue. With more focus on Tier-2 and Tier-3 cities under government schemes like Jal Jeevan Mission, EMS is expected to benefit significantly.
Jash Engineering is a niche player that supplies equipment used in water and wastewater projects — including gates, screens, valves, and pumping solutions. While it’s not a pure EPC company, it benefits directly from growth in water infrastructure orders.
Its consistent profitability, export capabilities, and strong domestic orders make it a high-quality midcap that supports larger EPC contractors. With growing demand for automated water handling systems, Jash Engineering is well-positioned.
4.Indian Hume Pipe Company Ltd
Indian Hume Pipe is one of the oldest listed players involved in water transmission infrastructure. It is known for its expertise in laying pipelines and creating large-scale water supply systems. The company works directly with state governments and urban local bodies.
Though not new, the stock remains underfollowed. It has a solid order book and strong execution history. With new tenders being floated regularly under Smart Cities and AMRUT 2.0 programs, Indian Hume Pipe stands to gain.
Welspun Enterprises, part of the Welspun Group, is a well-diversified EPC company that has made significant progress in the water and wastewater treatment space in recent years. It has delivered some of the largest municipal water supply projects and is increasingly taking up hybrid annuity model (HAM) contracts in this space.
It is financially strong and known for timely project execution. Though it also works in roads and highways, its growing water segment makes it an interesting long-term pick.
Why These Stocks Deserve Your Attention?
Growing Government Investment: India has committed billions of rupees to improve water supply and sanitation infrastructure under schemes like Jal Jeevan Mission, Clean Ganga Mission, and AMRUT 2.0.
Recurring Revenue Models: Many EPC contracts now include 5–10 year operation and maintenance periods, providing long-term revenue visibility.
Low Market Attention: Most of these stocks are still under-researched and not heavily owned by large institutions, which creates early-entry opportunities.
Supportive Policy Environment: As environmental rules tighten and cities expand, demand for clean water and proper sewage treatment will only rise.
Key Points to Watch Before Investing
Order Book Strength: Check if the company has a healthy backlog of projects.
Profit Margins: Consistent profit margins and low debt are good signs.
Execution Record: Past project delays or cancellations can be red flags.
Geographic Presence: Companies active in multiple states have more growth opportunities.
Conclusion
The water EPC sector in India is quietly becoming a strong wealth creation theme. As the country faces rising urban water demand and stricter environmental regulations, companies involved in building and maintaining water infrastructure are poised to grow steadily.
Stocks like Enviro Infra Engineers, EMS Ltd, Jash Engineering, Indian Hume Pipe, and Welspun Enterprises may not be headline-grabbing today, but they hold strong potential to deliver multibagger returns in the coming years — especially for early investors who recognize this hidden opportunity.
