The Public Works Department (PWD) in Delhi has initiated a significant shift in its approach to stormwater management by mandating the use of precast drain boxes instead of conventional cast-in-situ methods. This change is part of a citywide drainage remodelling exercise aligned with the drainage master plan, which has already seen 20 tenders issued. The new precast drain boxes are designed to enhance durability, reduce construction time, and minimize on-site pollution. PWD Minister Parvesh Verma highlighted that these boxes come with a 50-year warranty, ensuring a longer lifespan compared to traditional systems. While precast boxes will be used in areas with straight drainage lines, the PWD will continue to employ the cast-in-situ method in curves or complex connections to maintain proper water flow. This hybrid approach aims to balance efficiency with the challenges posed by existing infrastructure.
