Future-Ready Wastewater Treatment Plant for Dhaka
The reconstruction and expansion of the 200,000 m³/day Wastewater Treatment Plant in Pagla is one of Bangladesh’s largest urban sanitation initiatives. Executed under a Design-Build-Operate model for the Dhaka Water Supply and Sewerage Authority (Dhaka WASA), the Municipal Wastewater Treatment Plant will strengthen the city’s capacity to manage increasing sewage flows. The Wastewater Treatment Plant will also support the restoration of the Buriganga River.
Funded by the World Bank and Asian Infrastructure Investment Bank under the Dhaka Sanitation Improvement Project, this Wastewater Treatment Plant combines large-scale sanitation infrastructure with energy recovery and environmental protection. Among Wastewater Treatment Solutions Bangladesh, the project demonstrates how a modern Municipal Wastewater Treatment Plant can improve public health while supporting the sustainable growth of Dhaka.
Municipal Wastewater Treatment Plant for Growing Demand
The Municipal Wastewater Treatment Plant has an initial capacity of 200,000 m³/day and can be expanded up to 800,000 m³/day. The Wastewater Treatment Plant has been designed as a scalable solution for the long-term sanitation needs of a metropolitan region with more than 20 million residents. Within Wastewater Treatment Solutions Bangladesh, the expanded Wastewater Treatment Plant will provide dependable performance under increasing wastewater loads.
Wastewater Treatment Plant Scope and Execution
- Scope: Comprehensive DBO delivery covering design, engineering, supply, construction, installation and commissioning of the Wastewater Treatment Plant.
- Operations: Five years of operation and maintenance for the Municipal Wastewater Treatment Plant after commissioning.
- Technology: Activated sludge treatment with partial nitrification, anaerobic sludge digestion and biogas-based power generation for the Wastewater Treatment Plant.
- Impact: The Wastewater Treatment Plant will reduce untreated sewage discharge and strengthen the value of Wastewater Treatment Solutions Bangladesh.
Wastewater Treatment Solutions Bangladesh for a Sustainable Wastewater Treatment Plant
The Wastewater Treatment Plant uses an activated sludge process with partial nitrification to remove pollutants and improve treated effluent quality. Anaerobic digestion converts sludge into biogas, which can be used for power generation through gas engines. This approach reduces dependence on grid electricity and supports lower greenhouse gas emissions.
These systems enable the Wastewater Treatment Plant to combine reliable wastewater treatment with renewable energy recovery. The integration of biological treatment and sludge-to-energy systems positions the project among sustainable Wastewater Treatment Solutions Bangladesh for rapidly expanding urban centres.
Wastewater Treatment Companies in Bangladesh: Wastewater Treatment Plant Expertise
The Wastewater Treatment Plant will help reduce untreated sewage entering the Buriganga River and improve environmental conditions across Dhaka. The Municipal Wastewater Treatment Plant also supports public health, sanitation and urban liveability. Among Wastewater Treatment Companies in Bangladesh, WABAG brings the engineering and operational experience required for complex DBO infrastructure. The Wastewater Treatment Plant therefore contributes to long-term environmental protection and sustainable urban development.
