Tata Consulting Engineers supported the project through design and drawings review, procurement assistance, and construction supervision, ensuring consistency and quality across all locations. The team introduced several engineering innovations, including double-decker overhead tanks for land-constrained areas and two-tier sewage treatment plant layouts with 11 MLD basins to maximise capacity within limited footprints. Odour control systems and energy-efficient equipment were incorporated to improve operational sustainability. In Nainital, cured-in-place pipe technology was used to rehabilitate old sewer networks, minimising disruption and extending asset life. Rainwater harvesting was integrated into the conversion of soak pits, further enhancing the project’s environmental credentials.
