Rocla®  supplied almost one kilometre of 2100mm diameter reinforced concrete stormwater pipe for a major Melbourne Water drainage project at Knoxfield, in south-eastern Melbourne.

The Kent Park Drainage Scheme design, completed by URS Australia, will provide flood relief for residential and industrial properties by draining stormwater via the pipeline into a sediment basin and wetlands at Knox Park Retarding Basin in Knoxfield.

Flow is being directed away from an existing retarding basin in Gilbert Park, the site of a baseball field that is flooded several times a year. The new 6-cumec capacity pipeline can carry the overland flow from a 100-year ARI event, leaving the old basin at Gilbert Park as a standby for catastrophic storms.
