Enviro Infra Engineers order book crosses ₹4,600 crore

Key developments driving the latest order momentum

Enviro Infra Engineers has reported a sharp pick-up in recent order inflows across its core water and wastewater business and its newly entered Battery Energy Storage System (BESS) segment. Updates shared across multiple company and market disclosures point to a meaningfully higher order pipeline, supported by wins under government programmes such as AMRUT 2.0 and Swachh Bharat Mission. The company also highlighted its move into grid-scale storage through NTPC-related EPC contracts.

While some figures shared in different updates vary on the exact headline order book number, the underlying trend is consistent: Enviro Infra Engineers is adding larger-ticket projects across states, with a mix of EPC execution and long-duration operations and maintenance (O&M) commitments.

Recent wins from BUIDCO and sanitation projects in Maharashtra

In a management update on additions to the order book, Enviro Infra Engineers said that in Q4 it secured a major project worth ₹348 crore from BUIDCO (Bihar Urban Infrastructure Development Corporation). In the same update, it also referred to two sanitation projects in Pune and Nashik with a combined value of ₹824 crore, describing them as Swachh Bharat Mission projects.

Separately, another company update on the water and wastewater segment stated that two major projects worth approximately ₹972 crore were secured under Swachh Bharat Mission (Urban) 2.0 in Pune and Nashik, Maharashtra. The disclosures indicate the projects are linked to government sanitation programmes, though the reported combined value differs across the two references.

Entry into BESS through NTPC-linked EPC projects

The company marked its strategic entry into the BESS segment with four projects from NTPC. It described these as EPC projects with a combined capacity of 930 MWh and an approximate value of ₹1,070 crore. The locations cited for these projects include Uttar Pradesh, Assam, Karnataka, and Telangana.

In addition to the four-project pack, the company also referred to a recent acquisition of a 150 MWh BESS project in Bihar. It stated that these moves position it as a first mover in India’s 90 GW battery storage pipeline.

A separate order win disclosure also mentioned a specific BESS order from NTPC Limited valued at ₹405.71 crore (excluding GST), covering Battery Energy Storage Systems in Tanda, Uttar Pradesh and Bongaigaon, Assam, under an EPC scope.

Sewerage and wastewater projects under AMRUT 2.0

On the water and wastewater side, the company disclosed an EPC sewerage network and sewage treatment plant (STP) project in Aurangabad, Bihar, awarded by Bihar Urban Infrastructure Development Corporation Limited under AMRUT 2.0. The contract value was stated as ₹411.08 crore (including GST). The scope includes a 20 MLD Sewage Treatment Plant and associated sewerage network work, along with O&M responsibilities.

The company has also received a Letter of Acceptance from the Bhopal Municipal Corporation for a sewerage infrastructure project. The project scope includes the design, construction, and commissioning of a 273.369 km sewerage network in the north-east region of Bhopal, a 60 MLD STP, and intermediate pumping stations. The EPC portion is valued at ₹248.49 crore (excluding O&M and GST), with a 36-month EPC timeline followed by a five-year O&M period.

Additional municipal and utility orders across states

Beyond Bihar and Madhya Pradesh, Enviro Infra Engineers disclosed two new sewage treatment project orders worth ₹221.26 crore from the Bangalore Water Supply and Sewerage Board (BWSSB), including advanced reuse technologies.

The company also reported domestic project awards worth ₹306.30 crore for multiple STPs with 15 years of O&M in Chhattisgarh, covering municipal corporations in Ambikapur (Surguja), Rajnandgaon, and Korba.

Order book size and composition: multiple figures cited

Different disclosures in the provided material cite different order book snapshots:

• One update stated the execution order book is ₹4,800 crore.
• Another update said the order book “reached over ₹4,600 crore” and increased by ₹2,240 crore since March 2026.
• Another snapshot described a “current order book” of ₹3,000 crore, split as ₹2,000 crore execution and ₹1,000 crore O&M over 5 to 15 years.

The company also shared a category-wise mix in one update: ₹2,500 crore in water and wastewater treatment orders, ₹1,000 crore in renewable energy orders, and ₹1,100 crore in operations and maintenance.

Revenue and order intake targets disclosed by the company

Enviro Infra Engineers reported FY25 revenue of ₹1,066 crore and indicated a FY26 revenue target in the range of ₹1,450 crore to ₹1,500 crore. It also stated Q1 FY26 orders won of ₹1,178 crore, with a full-year order inflow target of ₹2,500 crore.

In another statement, the company said that the recent mix of BESS and water project wins provided clear revenue visibility of approximately ₹2,000 crore for FY27.

Stock move after Bhopal project announcement

Following the disclosure around the Bhopal Municipal Corporation Letter of Acceptance, the stock rose 3.33% to ₹247.95. The project includes both EPC execution and O&M services after completion, consistent with the company’s model of pairing construction contracts with annuity-like O&M revenue.

Summary table: key contracts and figures cited

Why the shift toward BESS matters alongside water EPC

The disclosed NTPC-linked storage projects indicate Enviro Infra Engineers is expanding beyond water and wastewater EPC into energy transition-linked infrastructure. The BESS contracts are described as EPC in nature, which aligns with the company’s execution capabilities, but in a different end-market than municipal water.

At the same time, the company’s recent wins continue to be anchored in government-led urban infrastructure programmes. AMRUT 2.0 and Swachh Bharat Mission-linked awards remain central to the pipeline, and several of the disclosed contracts include long O&M periods of five years to 15 years, which can stabilise revenue recognition beyond the EPC phase.

Conclusion

Enviro Infra Engineers’ latest disclosures show a broadened order pipeline combining municipal water and wastewater projects with a new foothold in BESS through NTPC-linked EPC contracts. With FY25 revenue disclosed at ₹1,066 crore and FY26 targets of ₹1,450 crore to ₹1,500 crore, the scale and mix of recently announced wins will be closely tracked through execution progress and further order intake updates, including the company’s stated full-year order inflow target of ₹2,500 crore.
