The pipelines installation route was complex and had to be planned in advance, it included exposed sections around the building, below ground culverts and down a stairwell in the building’s car park to the eventual end point at the DSD’s sewer main on Fung Cheung road in Yuen Long.
Custom made fabricated segment bends were supplied to specific pre measured angles to accommodate the pipes fixed route through the building stairwell, externally electrofusion moulded bends were used at standard 45º and 90º route changes.
