Mumbai's Malabar Hill Reservoir Project: Three-Tier Design Under Review
Among the first civic initiatives scrutinized by newly appointed Municipal Commissioner Ashwini Bhide is the long-delayed alternative reservoir project at Malabar Hill. Officials have now focused on a proposed three-tier design with a capacity of 52 million liters per day (MLD).
Design and Functionality of the Proposed Reservoir
The Water Supply Projects (WSP) department presented multiple configuration options to the municipal administration. The selected plan features a sophisticated three-level structure comprising an underground tank, a ground-level tank, and an upper-level tank. This design is engineered to ensure continuous water supply during periods when sections of the existing Malabar Hill reservoir require shutdown for essential repairs and maintenance.
Water will be strategically routed through the ground-level tank before being pumped upward to the upper reservoir. This operational methodology guarantees uninterrupted distribution to South Mumbai neighborhoods even during repair phases of the primary reservoir.
Background and Public Opposition
The urgent need for an alternative facility originates from the deteriorating condition of the aging Malabar Hill reservoir, which has exceeded its operational lifespan. Previous municipal plans to completely demolish and reconstruct the main reservoir faced substantial public resistance in September 2023. Residents and activists strongly opposed this approach because it would have significantly impacted the historic Hanging Gardens situated directly above the reservoir structure.
Following this opposition, authorities abandoned the demolition plan and instead adopted a strategy of phased repairs. However, these repairs are entirely dependent on the completion and operational status of the alternative reservoir facility.
Preserving Mumbai's Iconic Views
Commissioner Bhide has specifically instructed officials to conduct thorough examinations regarding whether the proposed three-tier structure might affect the legally protected "funnel of vision." This designated view corridor preserves uninterrupted panoramic vistas of Marine Drive and Backbay, which are considered essential visual heritage elements of Mumbai's urban landscape.
Civic officials identified several view-sensitive stretches that require protection, including the eastern flank extending from Priyadarshini Park to Nepeansea Road (designated as Sector 49), and the southern edge spanning from the wooded boundaries of Raj Bhavan along Walkeshwar Road to Walkeshwar Circle.
While preliminary assessments indicate the new reservoir structure is unlikely to obstruct these critical sightlines, municipal authorities emphasized that a comprehensive review is currently underway as part of standard due diligence procedures.
Site Selection and Project Timeline
A senior civic official disclosed that before settling on the current proposed location, municipal engineers evaluated two alternative sites—one situated near a local post office and another along Ridge Road. The plot adjacent to staff quarters is now being finalized as the preferred project location.
Once all necessary checks regarding the "funnel of vision" are conclusively completed, municipal authorities will commence the process of floating tenders for construction. "The administration maintains a positive outlook regarding initiating this crucial work," explained an official. "The existing reservoir has already surpassed its intended lifespan, creating an imperative need for an alternate tank to be prepared and operational."
The Malabar Hill reservoir project represents a critical infrastructure investment for Mumbai's water security, balancing technical requirements with environmental and visual conservation considerations under Commissioner Bhide's oversight.
