Enviro Infra Engineers Order Book Stands at ₹6,721 Crore: Water, Renewables and BESS Drive Growth
Enviro Infra Engineers Limited is entering FY27 with a strong and diversified order book of approximately ₹6,721 crore, providing significant revenue visibility across water and wastewater infrastructure, renewable energy and battery energy storage systems (BESS).
During its Q1 FY27 earnings conference call held on August 12, 2026, management said the company is focused on disciplined execution of its existing projects while continuing to build its pipeline across environmental infrastructure and clean energy.
₹6,721 Crore Total Order Book
The company’s total order book stood at approximately ₹6,721 crore as of the latest earnings call.
The order book is divided across two major business areas:
- Water & wastewater: ₹3,694 crore
- Renewable energy & BESS: ₹3,027 crore
Within the water and wastewater portfolio, ₹2,696 crore comprises execution orders and approximately ₹998 crore represents O&M orders.
In renewable energy and BESS, execution orders stood at approximately ₹1,948 crore, while IPP and O&M projects accounted for around ₹1,079 crore.
This diversified order book gives Enviro Infra Engineers exposure to both near-term project execution and longer-duration O&M and IPP revenue streams.
New ₹113 Crore Water Infrastructure Order
During Q1 FY27, the company secured a new EPC and O&M contract worth ₹113 crore from Sardar Sarovar Narmada Nigam Limited in Gujarat.
The order further strengthens Enviro Infra Engineers’ water infrastructure portfolio and adds to its existing execution pipeline.
₹2,696 Crore Water and Wastewater Execution Order Book
Water and wastewater treatment remains the company’s core business.
Management said the company has approximately ₹2,696 crore of execution orders in the water and wastewater segment. These projects are expected to be executed over approximately 18 to 24 months.
The company also has nearly ₹998 crore of water and wastewater O&M orders, providing a longer-duration revenue opportunity alongside project execution.
Renewable Energy and BESS Order Book
The renewable energy and BESS business is becoming an increasingly important growth engine for Enviro Infra Engineers.
The company has approximately ₹1,948 crore of renewable execution orders, while IPP and O&M projects account for another ₹1,079 crore.
Management said the renewable execution order book of approximately ₹2,000 crore is expected to be executed over 12 to 18 months.
The company’s renewable platform now covers solar, wind and BESS, giving it exposure across several areas of India’s clean-energy infrastructure market.
₹800 Crore Wind EPC Pipeline
The company is also seeing additional opportunities in the wind EPC business.
Management said the current wind EPC order pipeline is around ₹800 crore, and it expects another ₹500 crore to ₹600 crore of wind EPC projects to come into the business during FY27.
This pipeline could help replenish the company’s order book as existing renewable projects move into execution.
HAM Projects Add Long-Term Revenue Visibility
Enviro Infra Engineers is also expanding its Hybrid Annuity Model (HAM) portfolio.
The company currently has five HAM projects. Management said one project has been completed, while the Mathura project is close to completion. The Saharanpur project has completed three of eight milestones and is progressing ahead of schedule. Two newer projects are expected to commence work around October-November 2026, subject to the company’s project timelines.
The company has also submitted bids for two additional HAM projects, with evaluations underway. Management expects additional HAM opportunities to become available for bidding over the next three to four months as project DPRs progress.
O&M Business Provides Recurring Revenue
A significant advantage of the company’s order book is the long-term O&M component.
Water and wastewater turnkey projects, including EPC and HAM projects, typically come with O&M contracts ranging from 5 to 15 years, with an average duration of around 10 years.
Management estimates that the O&M portfolio could generate approximately ₹100 crore of topline at an average level. O&M also carries better EBITDA margins than the execution business, according to management.
In renewable energy, O&M associated with EPC projects can run for 5 to 12 years, while IPP projects can provide revenue over approximately 25 years.
₹7,000 Crore Water and Wastewater Bid Pipeline
Beyond the existing ₹6,721 crore order book, management sees significant opportunities in the water and wastewater market.
The company said approximately ₹7,000 crore of projects are currently available in areas where Enviro Infra Engineers has a strong interest and is bidding.
The pipeline is focused on wastewater-related projects, including sewage treatment plants, common effluent treatment plants and associated infrastructure, rather than renewable projects.
Management also highlighted opportunities arising from AMRUT 2, Namami Gange and projects supported by financing from institutions such as the World Bank, ADB and JICA.
₹2,000 Crore FY27 Revenue Guidance
The existing order book provides the foundation for the company’s ₹2,000 crore FY27 revenue guidance.
Management confirmed that the company continues to stand by this guidance despite Q1 revenue being below the quarterly run-rate implied by a simple seasonal calculation. Management noted that quarterly execution can vary and that the company expects to maintain its full-year guidance.
Margin Outlook
Management expects different profitability levels across its business segments.
For water and wastewater treatment, the company expects EBITDA margins of approximately 21%-22%.
For the renewable segment, covering solar, wind and BESS, expected EBITDA margins are around 15%-18%.
At a blended level, management expects EBITDA margins of approximately 19%-20%.
The company also indicated that higher raw-material costs have affected margins. Management said the raw-material price impact is approximately 1%-2% of overall topline, with some costs covered through price-variation clauses and some potentially absorbed by the company.
Order Book Provides Visibility, But Execution Remains Key
The ₹6,721 crore order book provides Enviro Infra Engineers with a substantial execution pipeline, but the pace at which these orders are converted into revenue will remain an important factor for investors.
The company is simultaneously expanding beyond its traditional water and wastewater business into renewable energy, wind EPC and BESS. Management said the company’s strategy is to build capabilities across these areas while maintaining disciplined execution and prudent capital allocation.
Key Numbers to Track
- Total order book: ₹6,721 crore
- Water & wastewater: ₹3,694 crore
- Renewable energy & BESS: ₹3,027 crore
- Water & wastewater execution: ₹2,696 crore
- Water & wastewater O&M: ₹998 crore
- Renewable execution: ₹1,948 crore
- Renewable IPP & O&M: ₹1,079 crore
- Wind EPC pipeline: ~₹800 crore
- Potential additional wind EPC projects in FY27: ₹500-600 crore
- Water/wastewater bidding pipeline: ~₹7,000 crore
- FY27 revenue guidance: ₹2,000 crore
Enviro Infra Engineers’ ₹6,721 crore order book is a key growth driver for the company. The portfolio is increasingly diversified, with water and wastewater remaining the core business while renewable energy, wind EPC and BESS provide additional growth avenues.
The combination of ₹2,696 crore of water and wastewater execution orders, ₹1,948 crore of renewable execution orders, long-term O&M contracts and a sizeable bidding pipeline provides multiple potential sources of future revenue.
For investors, the key monitorables will be order execution, fresh order inflows, working capital, project commissioning, renewable expansion and EBITDA margins.
