The Water and Sanitation Agency Faisalabad (WASA-F) is the statutory body responsible for the provision of water supply, sewerage, and drainage services in Faisalabad – Pakistan’s third largest city and the country’s primary industrial hub for the textile sector. Operating under the Government of Punjab, WASA-F manages the city’s wastewater collection and disposal infrastructure across two sewerage zones, serving a rapidly growing urban population.
Project Overview
Construction and operation of a 150,000 m³/day (33 MGD) wastewater treatment plant in Eastern Faisalabad, financed through a EUR 183 million concessional loan from under Danida Sustainable Infrastructure Finance (DSIF). The plant is expected to treat domestic and industrial wastewater from Channel No. 4, produce biogas-generated electricity for self-sufficient operation, and discharge treated effluent into the Gogera Branch Canal for agricultural irrigation, making it the largest wastewater treatment facility in the region.
The Context
Faisalabad is Pakistan’s third largest city and the industrial heartland of its textile sector. Decades of unregulated and unplanned urban growth have resulted in large volumes of both domestic and industrial wastewater being discharged into sewers and stormwater drains without treatment. These untreated flows are directed into natural water bodies, primarily the Madhuana Drain (Eastern Zone) and Paharang Drain (Western Zone), causing severe environmental degradation, groundwater contamination, and public health risks for surrounding communities.
The absence of wastewater treatment infrastructure has rendered canal surface water unfit for its intended irrigation and drinking water supply purposes, placing mounting pressure on Punjab’s Irrigation Department and water management systems. Recognizing the urgency of this challenge, the Government of Pakistan, Government of Punjab, and Embassy of Denmark signed a Memorandum of Understanding in 2017 to conduct a feasibility study, the first step in what has become a landmark bilateral infrastructure investment under the Pakistan-Denmark Green Framework Engagement.
The Approach
The project adopts a comprehensive engineering and environmental approach anchored in three phases: design, construction, and operation, with sustainability and energy self-sufficiency embedded from the outset. Following a feasibility study in 2018 and approvals by the Government of Denmark (2019) and Government of Pakistan (2020), a Loan Agreement was signed in September 2025 between Pakistan’s Ministry of Economic Affairs and Danske Bank together with DSIF for a fully concessional, interest-free loan worth EUR 183 million; DSIF will be covering all interest costs during both the draw-down and repayment periods, representing a subsidy of over 35% of contract amounts.
The project scope covers four core components:
The plant is designed to operate entirely on its own biogas-generated electricity, drawing only a minimal percentage from the public grid, a first-of-its-kind model for environmentally sustainable urban infrastructure in Punjab. Construction is led by Danish civil engineering firm Munck Civil Engineering A/S, with supervision by Danish consultancy NIRAS A/S.
Results & Impact
When fully operational, the Eastern WWTP will treat 150,000 m³ (33 million gallons) of wastewater per day, making it the largest wastewater treatment facility in the region. Treated effluent will be discharged into the Gogera Branch Canal, meeting the Irrigation Department of Punjab’s requirements for canal water use and supplying intake for the downstream drinking water treatment system.
The plant’s integrated biogas and energy recovery system will enable near-complete energy self-sufficiency, significantly reducing operational costs and carbon emissions. This represents a pioneering model of climate-resilient, circular urban infrastructure for Pakistan. Key outcomes include:
SDGs
• SDG 6 – Clean Water and Sanitation
• SDG 7 – Affordable and Clean Energy
• SDG 11 – Sustainable Cities and Communities
• SDG 13 – Climate Action
• SDG 17 – Partnerships for the Goals
Insights & Replication Potential
A key insight from this project is the effectiveness of concessional financing instruments, such as DSIF’s interest-free loan model, in unlocking large-scale sustainable infrastructure investment in developing countries. By covering all interest costs during both the draw-down and repayment periods, DSIF removes a critical financial barrier, enabling Pakistan to invest in infrastructure that would otherwise be unaffordable. The subsidy of over 35% of contract amounts illustrates the transformative leverage of development finance when structured around long-term environmental and social outcomes.
The integration of biogas and energy recovery into the plant’s design is a particularly significant innovation, demonstrating that wastewater treatment facilities in emerging markets can be engineered for near-complete energy self-sufficiency, reducing both operational costs and carbon footprints. This circular infrastructure model is directly replicable in other urban centres across Pakistan, particularly the Western Zone of Faisalabad, as well as in cities like Lahore, Multan, and Gujranwala facing similar wastewater management deficits.
The decade-long development arc of this project, from the 2017 MoU through feasibility study, dual government approvals, pandemic delays, and the 2025 loan signing, underscores the importance of sustained bilateral commitment and flexible programming in delivering complex infrastructure outcomes. Denmark’s consistent engagement through the Green Framework Agreement has been instrumental in bringing this project to financial close.
