Advanced WasteWater Treatment Plant Enhancing Bengaluru’s Water Security

The 150 MLD waste water treatment plant at K&C Valley in Bengaluru is a major urban sustainability project delivered under a Design-Build-Operate (DBO) model for BWSSB. Commissioned in 2022, the facility strengthens the city’s wastewater infrastructure while significantly improving the quality of natural water resources around Bellandur Lake and the downstream catchments.

Municipal Wastewater Treatment Plant with High-Efficiency Biological Treatment

Designed to meet the stringent norms of the Central Pollution Control Board (CPCB), the municipal wastewater treatment plant uses the Activated Sludge Process with Biological Nutrient Removal. This enables efficient removal of nitrogen and phosphorus, ensuring safe discharge and supporting environmental conservation in the region.

WasteWater Treatment Plant Delivering Water Reuse and Green Energy Generation

Beyond treatment compliance, the waste water treatment plant plays a vital role in Bengaluru’s broader water security. It generates over 5,450 crore litres of treated used water every year, serving as a backbone for replenishing lakes and water bodies in drought-affected regions like Kolar and Chikkaballapura. The treatment process ensures high-quality effluent suitable for recharge and reuse, supporting long-term regional water resilience.

Sludge-to-Energy Integration Strengthening Sustainability

A strong differentiator of this project is its advanced sludge management system. The sludge generated from the plant is converted to green energy, enabling the facility to meet 67% of its total power requirements. This circular approach lowers operational costs, reduces carbon footprint, and reinforces WABAG’s leadership among global wastewater treatment companies integrating energy-positive technologies.

Comprehensive DBO Scope for a Future-Ready Waste Water Treatment Plant

The project scope includes the full lifecycle delivery—design, construction, engineering, installation, commissioning, and a 10-year O&M period. This ensures long-term process reliability, optimized performance, and regulatory compliance across the wastewater management chain.

Advanced Treatment Process Ensuring Regulatory Compliance

The municipal wastewater treatment plant uses:

  • Activated Sludge Process with Biological Nutrient Removal
  • Fine screening and grit removal
  • Biological nutrient removal for nitrogen and phosphorus
  • Tertiary polishing steps ensuring high-quality treated water

These treatment steps ensure the sewage treatment plant consistently meets India’s environmental discharge standards.

Sludge Treatment and Green Energy Production

The sludge treatment component includes sludge thickening, digestion, and biogas-based power generation. This integrated sludge digestion system significantly reduces the plant’s dependency on the state power grid and supports sustainable operations.

Environmental and Social Impact for Bengaluru

The completion of this plant has improved the water quality of Bellandur Lake, reduced untreated discharge into surrounding water bodies, and enhanced local ecological health. By generating reusable water and renewable energy, the facility aligns with Bengaluru’s long-term sustainability goals.

A Model Among Wastewater Treatment Companies in India

With its combination of nutrient removal, high-volume reuse, and sludge-to-energy innovation, this plant strengthens WABAG’s position among leading wastewater treatment companies delivering circular, efficient, and future-ready solutions for large urban centers.
