Enviro Infra Engineers Secures New ₹126.78 Crore Varanasi Wastewater Project.

Enviro Infra Engineers Ltd (EIEL) has secured a domestic contract worth ₹126.78 crore (excluding GST) for wastewater management and ecological rejuvenation work in the Varanasi region of Uttar Pradesh, the company said.

The company received a Letter of Acceptance (LoA) from Uttar Pradesh Jal Nigam (Rural) on July 3, 2026, marking its latest win under the central government’s clean river initiative.

The project involves the development of a 45 million litres per day (MLD) sewage treatment plant (STP) along with associated network infrastructure for Pt. Deen Dayal Upadhyay Nagar (DDU Nagar).

The contract will be executed under the Hybrid Annuity Model (HAM), which combines initial construction with long-term operational responsibilities. A special purpose vehicle (SPV), Varanasi DDU Nagar STP Private Limited, will oversee implementation, following its incorporation on June 17, 2026.

Under the project plan, construction is expected to be completed within 18 months, followed by a three-month trial operation period to assess system performance. After commissioning, the SPV will manage operation and maintenance for a period of 15 years.
