The Lahore Wastewater and Drainage Management Project has secured formal approval from the Executive Committee of the National Economic Council (ECNEC) for a Rs 49–50 billion upgrade, including a 32-kilometre trenchless (micro-tunnelling) trunk sewer line from Larechs Colony to Gulshan-e-Ravi. A technical tender opening ceremony was held on January 29, 2026, attracting four international joint ventures. The project—funded by a $235 million AIIB loan—aims to serve 2.35 million residents across 15,600 acres and resolve long-standing drainage issues in central Lahore through a state-of-the-art disposal station and modern infrastructure.

A comprehensive Environmental and Social Impact Assessment (ESIA) has been finalized for the Larechs Colony to Gulshan-e-Ravi sewerage project, confirming it as an AIIB Category 'A' initiative. Key features include trenchless micro-tunnelling to minimize surface disruption, a 688 cusecs ultimate disposal station, and a 450 kW solar PV system at Gulshan-e-Ravi. The ESIA mandates strict mitigation for noise, vibration, groundwater protection, and community engagement—including a three-tier grievance redress mechanism and compensatory tree planting (1:10 ratio).

Larechs Colony is formally designated as the northern origin point for Lahore’s flagship wastewater infrastructure upgrade. The project route begins at Larechs Colony and extends via Gurumangat Road and Qartaba Chowk to Gulshan-e-Ravi, forming Line A of the 32.37 km trunk sewer network. This reflects the colony’s critical role in the city’s central zone drainage strategy and confirms its inclusion in the project’s 15,658-acre catchment area, benefiting approximately 2.35 million people.
