|Bishan Project is a 2.2m Diameter Sewer pipe 3Km long project. It is positioned next to HDB township in a heavily crowded urban region. Our Sewer line must go over MRT line and Under CTE bridge. Right next to the Bishan River is where our Jacking line and shaft are located. Therefore, Bishan River must be protected from contamination.
