Project data

Location: Western Region, Singapore

The Public Utilities Board (PUB) of Singapore is currently constructing link sewers for the Deep Tunnel Sewer System (DTSS) phase 2 projects along Common Wealth Avenue, Toh Tuck, Boon Lay Way and the International Business park areas.

The work requires supplying, lay and installing reinforced concrete sewer pipes and the construction of permanent manholes.

PERI Singapore utilized the following systems for the entirety of this project:
