Lahore, Oct 11, 2025 — Pakistan has approved construction of the country’s largest-ever wastewater treatment plant in Lahore, marking a major step toward improving urban sanitation, river pollution control, and environmental sustainability in Punjab.
The project, known as the Babu Sabu Wastewater Treatment Plant, has been officially cleared by the Central Development Working Party (CDWP). It will be one of Pakistan’s most advanced sewage treatment facilities, aimed at processing millions of gallons of wastewater before it flows into the River Ravi.
A Landmark Project for Urban Sanitation
Officials confirmed that 836 acres of land were previously acquired for the plant site in the Babu Sabu area. With an estimated cost of Rs 52 billion, the initiative is a core component of Punjab’s plan to revive the River Ravi and reduce environmental degradation caused by decades of untreated sewage discharge.
According to the Punjab Housing Department, the first phase will focus on treating sewage from Cantt Drain, Multan Road, and Gulshan-e-Ravi — three of Lahore’s most heavily polluted drainage channels.
The phase will be executed in partnership with Agence Française de Développement (AFD), the French development agency, which will provide both technical and financial assistance.
Massive Capacity to Clean Lahore’s Waterways
Once operational, the first phase of the facility will treat 88 million gallons per day (MGD) of wastewater. After full expansion, the plant’s total capacity will reach 198 MGD, significantly cutting the flow of untreated sewage into the River Ravi.
Officials said the project is expected to take about four and a half years to complete. It is part of a larger government framework to build six wastewater treatment plants across Lahore, ensuring that all urban sewage is fully treated before disposal.
Environmental and Health Benefits
Environmental experts have praised the initiative as a critical milestone in Pakistan’s fight against water pollution.
They emphasize that the project could serve as a model for other cities such as Karachi and Faisalabad, which face similar sanitation and wastewater management challenges.
The treated water is expected to be reused safely in agriculture and industry, supporting sustainable practices while protecting public health and reducing the environmental footprint of Pakistan’s second-largest city.
“This plant represents a turning point in how Pakistan manages its urban wastewater,” said one environmental analyst. “It will not only clean Lahore’s waterways but also improve long-term water security for millions.”
Government’s Vision for a Cleaner Future
Authorities say the Babu Sabu Wastewater Treatment Plant reflects the government’s broader urban resilience and sustainability strategy, aligning with the Pakistan Environmental Protection Act and the Punjab Clean Water Initiative.
Once completed, it will help revitalize the River Ravi ecosystem, improve public health outcomes, and support the government’s commitment to the UN Sustainable Development Goals (SDGs) — particularly Goal 6: Clean Water and Sanitation.
