DN600 SN16 RailPipe replaces conventional drop shaft outfall design
Fränkische’s SN16 RailPipe DN600 has been installed on a particularly important outfall drainage requirement, with Geelong City Council, on a very steep slope.
By utilizing the superior strength and durability of RailPipe, the consultants (Spiire) were able to remove the requirement of drop shafts, down the 15% gradient hill to Port Philip Bay, saving the council time and money.
Council based on the velocity design requirements of 10m/s, with a design flow of 1.9cumsec. These flows were handled easily by installing 2 x DN600 RailPipes side by side, anchored off periodically with concrete collars.
The installation was carried out by the councils civil drainage works team, within a 2 week period.
