The Mumbai Sewage Disposal Project (MSDP) Stage II, PST-1 is a key component of a larger initiative aimed at improving the sewage collection collection, treatment, and disposal systems in Mumbai to reduce environmental pollution and enhance urban infrastructure. This phase involves the construction of underground sewage tunnels to upgrade wastewater management infrastructure in critical areas, such as Malad, with the use of a TBM provided by Terratec.

For this project, Unicrane has supplied 6 sets of universal ring molds with the specification OD 3.6m × 1.2m × 0.2m (5+1P/R) for this project. These molds are essential for the construction of tunnel segments that will form part of the sewage disposal system, ensuring that the infrastructure meets high safety and durability standards.
