The scope includes the Design, Engineering, Procurement, Construction and Commissioning (‘EPC’) of the wastewater treatment facilities along with biogas-based power generation. The STPs will be based on the Activated Sludge Process integrated with a Biological Nutrient Removal system. The TTP at Byramangala will utilize Ultrafiltration to produce high-quality treated water suitable for distribution to surrounding water bodies. It is worth noting that, WABAG had previously executed the first phase of the Bellandur facility and has now been awarded the second phase as well. The EPC scope of the facilities is scheduled for completion within 36 months, followed by a 7-year Operations and Maintenance (‘O&M’) period, during which WABAG will ensure efficient and reliable plant performance. The Wastewater Treatment facilities at Byramangala and Bellandur will significantly strengthen Bengaluru's wastewater treatment and water infrastructure, addressing the city's growing challenges arising from rapid urbanization. The facility will incorporate anaerobic sludge digestion with biogas- based captive power generation, reducing greenhouse gas (‘GHG’) emissions, lowering the plant's energy footprint, enhancing operational efficiency, and promoting resource recovery. By integrating the treatment technologies with renewable energy generation, the project will support Bengaluru's long- term water security while advancing its sustainability and circular economy objectives. Commenting on the order wins, Mr. S. Natrajan, Vice President & Head – Sales and Marketing, India Cluster, said: “Securing these twin wins from BWSSB reinforces WABAG's leadership in India's municipal wastewater treatment sector and underscores its commitment to delivering sustainable, resilient, and future-ready water infrastructure. The energy-efficient wastewater treatment facilities, integrated with biogas-based power generation, will establish a scalable model for resource recovery, circularity, and energy optimization while significantly enhancing Bengaluru's sewage treatment capacity, promoting environmentally responsible wastewater management, supporting Karnataka's water security objectives, and strengthening the long-term sustainability and resilience of the city's water ecosystem.” Order Classification Small Medium Large Major Mega Domestic (in INR Crores) Upto 100 100 to 250 250 to 600 600 to 1,000 Above 1,000 International (In USD Millions) Upto 10 10 to 30 30 to 75 75 to 150 Above 150 STOCK EXCHANGE INTIMATION VA TECH WABAG LIMITED | WABAG House, No.17, 200 Feet Thoraipakkam – Pallavaram Main Road Sunnambu Kolathur, Chennai 600 117, India.
