Rainwater Tanks

Do I need development approval to install a rainwater tank?

In some circumstances rainwater tanks which meet certain criteria do not constitue development and therefore do not require development approval.

If your proposed rainwater tank:

  • is part of a roof drainage system;
  • has a total floor area not exceeding 10 square metres;
  • is located wholly above ground; and
  • has no part higher than 4 metres above the natural surface of the ground then it may not require development approval.
