Where can you build Sewerage systems in NSW?
“Sewerage systems” is a defined term in the NSW planning system, and every council’s Local Environmental Plan decides which zones allow it. Across 147 council LEPs it is permitted in 31 zones and prohibited in 31.
Zone by zone, across 147 NSW councils
Each row counts councils, not properties. “Without consent” means no application is needed; “with consent” means a development application. “Can’t say” is not a ban — those councils have not addressed this use in that zone at all.

How those answers were reached. 1,471 of the “prohibited” answers and 508 of the “with consent” answers come from the zone’s catch-all row — the scheme does not name this use in that zone, but it says what happens to everything it has not named. That is a real answer, not a guess, and it is the reason a count of explicit listings would tell you the opposite in some zones.
What this page cannot tell you
Which zone your land is in, and whether your project is characterised as a sewerage systems in the first place. The first is a question about an address; the second is a planning judgement. Check an address for the zone and the overlays on it.
Frequently asked questions
Are sewerage systems allowed in every council in New South Wales?
No. Each council’s Local Environmental Plan has its own land use table, and they differ. This page counts, zone by zone, how many of the 147 NSW council LEPs permit it, prohibit it, or say nothing either way.
My zone shows a number under “Can’t say” — what does that mean?
It means those councils neither name this use in that zone nor have a catch-all row covering everything they have not named. It is not a ban and it is not permission. Only an explicit listing in the prohibited rung, or a catch-all that prohibits, is a prohibition.
Does this tell me whether my project counts as sewerage systems?
No, and that is deliberate. Deciding which defined term your project is called is a planning judgement, not something this page can do for you. Search your address for the zone, then talk to a planner about how the project is characterised.
