What matters for plumbing in Wollongong

Wollongong bans absorption systems outright on land with slope instability, loose sand, collapsing clays, rock and shale, slopes over 15 percent or extensive paving, unless an engineer designs it and a geotechnical engineer with local knowledge signs off. Where they are allowed, roof water must first pass through a 5,000 litre rainwater tank, and the trench must sit at least 3 m from boundaries and 5 m from all buildings.
