VA Tech WABAG Secures ‘Large’ BWSSB Order for Energy-Efficient Wastewater Treatment Projects

What Happened ?

key details

Project Scope:

• WABAG has been awarded the Design, Build and Operate (DBO) contract for a 100 MLD Sewage Treatment Plant (STP) and a 25 MLD Tertiary Treatment Plant (TTP) at Byramangala, Bengaluru.
• The company has also secured the Design, Build and Operate (DBO) contract for a 60 MLD Sewage Treatment Plant (STP) at Bellandur, Bengaluru.
• The order covers the complete project lifecycle, including engineering, procurement, construction, commissioning and long-term operations. 

Technology & Engineering:

• The wastewater treatment plants will be developed using the Activated Sludge Process (ASP) integrated with a Biological Nutrient Removal (BNR) system.
• The 25 MLD Tertiary Treatment Plant at Byramangala will incorporate Ultrafiltration (UF) technology to produce high-quality treated water suitable for discharge into surrounding water bodies.
• The facilities will also include biogas-based captive power generation, helping reduce greenhouse gas emissions while improving energy efficiency and operational sustainability.

Sustainability Benefits:

• The project is designed to improve Bengaluru’s wastewater treatment capacity amid increasing urbanisation.
• Renewable energy generation through biogas will lower the plants’ energy footprint and promote resource recovery.
• The facilities support circular economy principles by combining wastewater treatment with energy optimisation and water reuse.
• The project is expected to strengthen the city’s long-term water security while contributing to environmentally sustainable infrastructure development.

Long-Term Contract:

• The EPC portion of the project is scheduled for completion within 36 months.
• Following commissioning, WABAG will operate and maintain the facilities for 7 years, providing recurring service revenue and ensuring efficient plant performance over the contract period. 

Strengthening Existing Relationship:

• WABAG previously executed the first phase of the Bellandur Sewage Treatment Plant.
• The award of the second phase further strengthens the company’s relationship with BWSSB and reinforces its position as a preferred partner for large municipal wastewater infrastructure projects. 

Order Classification:

• The contract has been classified as a ‘Large’ domestic order under WABAG’s order categorisation framework.
• As per the company’s classification, a Large domestic order represents a project with an order inflow value ranging between ₹250 crore and ₹600 crore.
• The company also confirmed that the project is not a related-party transaction, and neither the promoter nor the promoter group has any interest in the awarding authority.

Note:

• The BWSSB order strengthens WABAG’s municipal water infrastructure portfolio by combining advanced wastewater treatment technologies with renewable energy integration and a long-term O&M commitment.
• Beyond expanding the company’s domestic order book, the project reinforces WABAG’s expertise in delivering sustainable, energy-efficient water infrastructure that supports urban water security and circular economy objectives.

Risk Analysis

Summary:

• The BWSSB order strengthens WABAG’s municipal wastewater order book and provides long-term revenue visibility through a combination of EPC execution and a seven-year O&M contract.
• However, successful project execution, timely commissioning and operational performance will be critical to realizing the full benefits of the contract.

Key Risks:

• Execution Risk: The project involves the design, engineering, procurement, construction and commissioning of multiple wastewater treatment facilities. Delays in execution could impact project timelines and cash flow realization. 
• Timeline Risk: The EPC scope is scheduled to be completed within 36 months. Any delay arising from approvals, supply chain constraints or construction challenges could postpone project completion. 
• Operational Performance Risk: WABAG will operate and maintain the facilities for seven years after commissioning. Maintaining treatment efficiency, plant availability and service quality throughout the contract period will be essential for successful execution. 
• Technology Integration Risk: The project integrates advanced wastewater treatment technologies, including Biological Nutrient Removal (BNR), Ultrafiltration (UF) and biogas-based captive power generation. Efficient integration and commissioning of these systems will be important to achieve the intended environmental and operational outcomes. 
• Public Infrastructure Dependency: As the project is awarded by a government utility, execution remains subject to coordination with public authorities and adherence to contractual milestones throughout the implementation period.

Worst Case:

• If project execution is significantly delayed or operational performance does not meet contractual requirements, commissioning timelines, revenue recognition and expected long-term operational benefits from the contract could be adversely affected.

Risk Level: Low

Company Commentary

• WABAG stated that securing the two BWSSB projects reinforces its leadership in India’s municipal wastewater treatment sector. 
• The company believes the energy-efficient wastewater treatment facilities, integrated with biogas-based power generation, will serve as a scalable model for resource recovery, circularity and energy optimisation. 
• Management highlighted that the projects will significantly enhance Bengaluru’s sewage treatment capacitywhile promoting environmentally responsible wastewater management and supporting Karnataka’s long-term water security objectives. 
• WABAG emphasized that the facilities will strengthen the sustainability and resilience of Bengaluru’s water ecosystem by combining advanced treatment technologies with renewable energy generation. 
• The company reiterated its commitment to delivering sustainable, resilient and future-ready water infrastructure through innovative technologies and efficient lifecycle project management.
