Transforming Wastewater into Green Energy while safeguarding the Yamuna River and ensuring Sustainable Sanitation for New Delhi.

Under the ambitious Yamuna Action Plan, WABAG secured a contract for the rehabilitation and upgradation of the Rithala Wastewater Treatment Plant (WWTP). This critical project, funded by the Japan International Cooperation Agency (JICA), involves modernizing the plant to treat 182 million litres of wastewater per day, significantly enhancing New Delhi’s wastewater management infrastructure. The project is not just about upgradation—it sets a precedent for integrating energy efficiency with wastewater treatment.

Project Features:

• Scope: DBO: Design, supply, construction, and commissioning of the WWTP, including a unique 11-year Operation & Maintenance (O&M) contract.
  Technology:
• Mechanical and biological wastewater treatment: advanced biological treatment processes, including MLE process for effective nitrogen removal and along with bio the chemical precipitation for phosphorus removal. 
• Anaerobic sludge treatment including a forward-thinking biogas power generation unit was designed and installed by WABAG, converting sewage into energy and reducing the plant’s reliance on the external power grid—an exemplary step toward the waste-to-energy revolution.
• Impact: The Rithala WWTP is a key step in reducing pollution in the Yamuna River, ensuring sustainable wastewater management for New Delhi, and transforming waste into a valuable resource by producing green energy.
