Most of Woy Woy was built in the 1950s–70s after rail electrification in 1960. The original galvanised steel pipes are now 55–65+ years old — well past their 40–50 year lifespan.

Woy Woy sits just 2–6 metres above sea level. During heavy rain and king tides, Brisbane Water pushes up through stormwater drains, flooding low-lying properties and overwhelming private drainage.

Woy Woy is surrounded by water on three sides — Brisbane Water, Broken Bay, and the inlet. Salt-laden air accelerates corrosion on pipes, fittings, and hot water systems faster than inland suburbs.
