Overview

• The Delhi Jal Board has issued requests for proposals to hire consultants for a 2043 sewerage masterplan, with selection expected by October 3 and a 15-month study window.
• The programme targets zero untreated discharge into the Yamuna and prioritizes ecological restoration with phased actions spanning immediate, short-term, and long-term measures.
• Planned methods include AI-enabled planning and drone-based topographic surveys to map major and minor drains, validate system performance, and guide upgrades.
• An operational shift to a ‘one zone–one operator’ model is proposed, dividing the city into four zones managed by single agencies to streamline maintenance and accountability.
• DJB cites an estimated 990 MGD of wastewater generation against 667 MGD installed treatment capacity, leaving roughly 227 MGD untreated, and the plan calls for expansions, upgrades, and solutions for underserved settlements.
