Enviro Infra Engineers Limited has secured a 130.14 crore rupee contract from Uttar Pradesh Jal Nigam (Rural) to build a 60 MLD sewage treatment plant in Varanasi. Executed via a specialized SPV under the Namami Gange Programme, the project spans 24 development months followed by 15 years of operation.
MUMBAI — Enviro Infra Engineers Limited announced on Friday, July 3, 2026, that it has secured a major domestic contract valued at 130.14 crore rupees (excluding GST) for wastewater infrastructure development in Varanasi, Uttar Pradesh. Awarded by Uttar Pradesh Jal Nigam (Rural), the initiative falls directly under the central government's flagship Namami Gange Programme. The structural development marks a crucial modernization step for environmental utilities in Northern India, aiming to expand active sanitation processing capacities to keep pace with rapid urban growth along the Ganga River basin.
Technical Scope and HAM Execution Framework
According to a regulatory filing submitted to national stock exchanges, Enviro Infra Engineers Limited received the formal Letter of Acceptance (LOA) from the state department on July 3, 2026, following an initial authorization dated July 1, 2026.
The extensive project encompasses the development of a 60 MLD (Million Liters per Day) Sewage Treatment Plant (STP) alongside associated infrastructure networks at Lohta, Varanasi.
The construction will be executed via a specialized special purpose vehicle (SPV) titled Varanasi Lohta STP Private Limited, which was previously incorporated by the parent entity and disclosed to the market on June 17, 2026.
The regulatory filing outlines that the administrative model chosen for this domestic project is the Hybrid Annuity Model (HAM) Public-Private Partnership (PPP) mode.
Under the HAM structure, the financial layout optimizes fiscal risk sharing between the public asset owner and the corporate builder, providing structured milestone payments during the execution phase before transitioning to regular annuity payouts over the long term.
Construction Timelines and Long-Term Service Terms
The operational timeline dictated by Uttar Pradesh Jal Nigam (Rural) mandates a multi-tier schedule for the engineering firm. Enviro Infra Engineers Limited has been allotted an explicit 21-month window to complete the core infrastructure construction phase. Following physical completion, a mandatory 3-month trial operations period will be carried out to guarantee system stability and effluent quality standards.
Crucially for institutional investors assessing corporate revenue visibility, the contractual terms include a prolonged 15-year Operation and Maintenance (O&M) period following the trial phase. This long-term contract structure guarantees steady, recurring service revenues for Enviro Infra Engineers Limited over the next decade and a half, insulating the corporation's order book from immediate cyclical construction slowdowns.
Direct Benefits for Citizens and Environmental Investors
For residents of Varanasi and the surrounding Lohta suburbs, the installation of a 60 MLD treatment facility significantly upgrades local municipal public health. Directing household and industrial effluent through a modern processing facility prevents untreated sewage from entering natural waterways, directly supporting the ecological preservation goals of the Namami Gange initiative.
From a market perspective, the project confirmation expands the specialized infrastructure footprint of Enviro Infra Engineers Limited within the high-demand environmental engineering sector. The company officially clarified to market regulators that the contract does not involve related-party transactions, and no promoter or group entities possess any financial interest in the awarding state department, verifying standard arm's-length compliance protocols.
