On 21 August 2026, the Executive Committee of the National Economic Council (Ecnec) cleared Rs56 billion for what is described as the country's largest wastewater treatment facility, to be built at Babu Sabu in Lahore (Dawn). A senior official familiar with the meeting said the project is expected to launch within six months once bidding is complete.
Key takeaways
- Ecnec approved Rs56bn for the facility on 21 August 2026, with launch targeted within six months after bidding (Dawn).
- The site is at Babu Sabu, Lahore, and the project is described as the city's first wastewater treatment project (Dawn).
- Funding is split 24pc from the Housing, Urban Development and Public Health Engineering Department and 74pc from Agence Française de Développement (AFD) (Dawn).
- Build programme: 12-month pre-construction, 42 months construction, 36 months operations and maintenance (Dawn).
- Phase I will treat flows from central Lahore, including the Cantt Drain, Multan Road and Gulshan-i-Ravi pumping stations, before discharge to the Ravi (Dawn).
What happened
According to a report published 22 August 2026, the federal government has approved Rs56bn for the country's largest wastewater treatment plant, to be sited at Babu Sabu in Lahore (Dawn). The Ecnec meeting on 21 August 2026 gave the clearance, and a senior official told the paper that "the project will be executed at Babu Sabu (Lahore)" and that it is "the first ever wastewater treatment project in Lahore" (Dawn).
The scheme is aligned with the approved master plan of Water and Sanitation Agency (Wasa) Lahore and is intended to give the city its first large-scale wastewater treatment facility (Dawn). Before reaching Ecnec, the housing department secured Provincial Development Working Party approval on 13 August 2026 (Dawn).
Phasing and end use
Construction is split into three phases: a 12-month pre-construction stage, 42 months of construction, and a 36-month operations and maintenance (O&M) period (Dawn). Under Phase I, sewage from central Lahore, including flows from the Cantt Drain, Multan Road and Gulshan-i-Ravi pumping stations, will be treated and discharged into the Ravi, with the stated goal of improving the city's environmental health (Dawn). Phase II scales up to "composting, RDF production, biochar manufacturing, fertilizer pelletization, brick production and phosphorus recovery," while Phase III targets "zero storage & circular economy" activities (Dawn).
Funding split and next steps
Of the Rs56bn total, 24pc will come from the Housing, Urban Development and Public Health Engineering Department and 74pc from the Agence Française de Développement, the French government funding agency (Dawn). The launch is expected within the next six months once the bidding process is complete (Dawn).

Specification read
No daily flow figure, population equivalent, or BOD/COD loading was reported for the Lahore facility, so the throughput numbers below are general industry ranges, not from the sources (general industry range, not from the sources). A "country's largest" municipal wastewater plant in a metropolitan area the size of Lahore typically sits in the high hundreds of MLD range, with a coarse screen → grit removal → primary clarification → biological stage (commonly A2O, MBBR, MBR or SBR) → tertiary filtration and disinfection train, followed by sludge thickening, dewatering and, for a reuse-driven project like this one, further treatment to feed composting, RDF, biochar and fertilizer-pellet lines. The Ecnec decision bears on the headline stage — greenfield, multi-phase capital build with a built-in reuse roadmap — and on the procurement window, since AFD-funded projects typically run international competitive bidding with French and EU eligibility conditions.
If your plant is a brownfield municipal works in the 50-500 m³/day class treating mixed domestic sewage at typical raw BOD of 200-300 mg/L and you face tightening reuse or river-discharge rules, this approval signals two things worth tracking: a regional benchmark for what a "first large-scale" facility is being scoped to do (discharge plus reuse products in one contract), and a likely near-term AFD-financed tender pipeline in Punjab that you can pre-position for. Hydropure Water supports Industries We Serve with municipal-grade treatment trains and can scope a comparable Municipal package from screening through disinfection.
FAQ
What was approved on 21 August 2026? Ecnec approved Rs56bn for what the source describes as the country's largest wastewater treatment plant, to be built at Babu Sabu in Lahore, with launch expected within six months after bidding (Dawn).
Who is paying for the Lahore wastewater plant? Funding is split 24pc from the provincial Housing, Urban Development and Public Health Engineering Department and 74pc from the Agence Française de Développement, the French government funding agency (Dawn).
How long will construction take? The reported programme is a 12-month pre-construction stage, 42 months of construction, and a 36-month operations and maintenance period (Dawn). For a comparable turnkey municipal plant, total lead time from award to mechanical completion commonly runs 24-48 months once design is fixed (general industry range, not from the sources).
What will the treated water be used for? Phase I discharges to the Ravi; Phase II adds reuse programmes covering composting, RDF production, biochar manufacturing, fertilizer pelletization, brick production and phosphorus recovery, with Phase III targeting zero storage and a circular economy (Dawn).
