The TWRP Pipeline-C1 Tunnel Project is part of Singapore's Tuas Water Reclamation Plant (TWRP), a major initiative aimed at enhancing Singapore's water treatment and reclamation capabilities. This project involves the construction of underground tunnels to house pipelines, supporting the expansion of the TWRP to meet the growing demand for water reclamation and environmental sustainability.

For this project, Unicrane has supplied 2 sets of left taper ring moulds and 1 set of right taper ring moulds (OD 6.55m × 1.6m × 0.275m, 8P/R) for the construction of durable tunnel segments required for this critical infrastructure project. The TWRP expansion is expected to strengthen Singapore's position as a global leader in water management and sustainability.
