VA Tech Wabag Secures Major BWSSB Wastewater Project

CHENNAI, India — Pure-play water technology multinational VA Tech Wabag Limited has formally secured a significant municipal order from the Bangalore Water Supply and Sewerage Board (BWSSB). The contract entails the design, build, and operation of two massive, energy-efficient wastewater treatment facilities in Bengaluru.

The regulatory filing defines the financial scope of this domestic order within the "Large" category, representing a transaction value between ₹2.5 billion and ₹6 billion (₹250 to ₹600 Crores). This critical infrastructure advancement comes at a time when rapid urbanization continues to challenge water security and municipal resource recovery across Karnataka's capital.

Infrastructure Breakdown and Technical Execution

The project scope focuses on the Design, Build, Operate (DBO) model for two major sewage infrastructure hubs in Bengaluru. VA Tech Wabag will spearhead the complete execution cycle, including Engineering, Procurement, Construction, and Commissioning (EPC).

The infrastructure development involves two targeted municipal plants:

• Byramangala Facility: The construction of a 100 million-liters-per-day (MLD) Sewage Treatment Plant (STP). This facility will utilize advanced ultrafiltration technology in its Tertiary Treatment Phase to process highly purified water suitable for replenishing surrounding lakes and water bodies.

• Bellandur Facility: The setup of a 60 MLD Sewage Treatment Plant. Notably, VA Tech Wabag previously executed the initial phase of this facility and has been retained to construct and integrate this secondary expansion phase.

Both facilities are designed around the Activated Sludge Process integrated with a Biological Nutrient Removal system to effectively eliminate nitrogen and phosphorus contaminants before discharge.

Direct Impact on City Carbon Footprint and Energy Efficiency

A fundamental pillar of this municipal expansion is operational sustainability. Both the Byramangala and Bellandur facilities will introduce anaerobic sludge digestion alongside biogas-based captive power generation systems. By converting biological waste into usable gas energy, the plants will significantly lower their external grid dependence and energy footprints.

This framework aligns directly with national circular economy objectives, enabling resource recovery while heavily curtailing urban greenhouse gas emissions. The engineering phase is legally mandated for completion within a strict 36-month window, which will be followed by a prolonged 7-year comprehensive Operation and Maintenance (O&M) period managed entirely by Wabag.

Corporate and Market Background

The win consolidates VA Tech Wabag's strong financial visibility moving through the 2026 fiscal cycle. According to historical disclosure data via the National Stock Exchange of India (NSE), the company entered the year maintaining an extensive global order book valued above ₹172 billion, backed by an asset-light operating blueprint and a net cash-positive posture maintained for consecutive years.

Municipal contracts of this scale bolster the company's continuous baseline revenue pipeline over the multi-year EPC construction horizon.

Official Sources Section

According to the official corporate disclosure submitted to the BSE Limited and the National Stock Exchange under Regulation 30 of the SEBI (Listing Obligations and Disclosure Requirements) Regulations, 2015, the project contains no promoter or related-party transactional interests and has been cleared entirely on an arm's length basis.

Official Statement

"This significant order win underscores our technological leadership and commitment to developing resilient, sustainable water infrastructure," stated Mr. S. Natrajan, Vice President & Head of Sales and Marketing for the India Cluster at VA Tech Wabag. "The deployment of these energy-efficient wastewater treatment facilities will establish a highly scalable model for resource recovery and energy optimization while significantly upgrading Bengaluru's long-term municipal sewage capacity."

Why It Matters

For residents and environmental stakeholders in Bengaluru, this development marks a measurable step toward restoring heavily stressed urban aquatic systems like Bellandur. The implementation of circular economic infrastructure ensures that the municipality spends less taxpayer money on grid power for sanitation, while advanced tertiary ultrafiltration ensures that treated, recycled water returns safely to regional ecosystems, protecting public health and stabilizing the local water table.

Key Facts at a Glance

• Total Project Financial Valuation: Categorized officially as a "Large" order valued between ₹250 Crores and ₹600 Crores (₹2.5 to ₹6 billion).

• Capacity Capabilities: Adds a cumulative 160 MLD of processing capability across Byramangala (100 MLD) and Bellandur (60 MLD).

• Execution Timeline: Set at a rigid 36-month EPC track followed by a 7-year operational maintenance contract.

• Green Framework Integration: Deploys Activated Sludge Processes alongside biogas power generation to shrink urban greenhouse gas outputs.

FAQ Section

What is the value of the new BWSSB contract awarded to VA Tech Wabag?

The contract is officially classified as a "Large" order inflow, placing its economic value between ₹250 Crores and ₹600 Crores (₹2.5 to ₹6 billion rupees).

Where will the new facilities be constructed?

The facilities will be executed inside the municipal limits of Bengaluru, specifically upgrading infrastructure at Byramangala and Bellandur.

What specific technologies will be utilized in these STPs?

The facilities rely on the Activated Sludge Process paired with Biological Nutrient Removal. The Byramangala node will also utilize ultrafiltration for high-tier water recycling, and both locations will utilize biogas-based captive power generation systems.

How long will the project take to complete?

The Engineering, Procurement, and Construction (EPC) scope is scheduled for completion within 36 months, which automatically transitions into a 7-year Operation and Maintenance (O&M) lifecycle phase.
