Sewerage Scheme to serve Pulau Punggol Barat Contract 3 – Proposed Pumping Mains and Pipe Bridge

Seletar, Singapore

This project allows us to contribute to efficient wastewater management and preserve a clean environment for surrounding communities.

Located in Seletar, the Punggol Barat C3 project will serve as a channel for the loads from the Construction Industries Park at Pulau Punggol Timor for treatment at the Changi Water Reclamation Plant, which we also played a part in in our C22B project. Just as we are now commissioning our C22B project in 2022, we are embarking on the transport system to feed wastewater into it!
