Gorokan has the oldest housing stock in the corridor — some homes date back to the 1950s
when the suburb transitioned from holiday shacks to permanent housing. Original clay sewer lines
and galvanised iron supply pipes are well past end of life.

Gorokan's dual lake frontage means low-lying lots near the water's edge experience groundwater
infiltration into cracked clay sewer laterals, particularly during wet seasons. This increases
sewer load and causes repeat blockages.
