Stormwater can be a good alternative to mains water for many purposes.

Harvesting stormwater involves capturing, treating, managing and storing runoff from urban areas. It’s different from harvesting rainwater as it comes from drains rather than roofs.

If you’re planning on capturing stormwater it’s important to do it safely. This is because stormwater runoff from urban areas is often contaminated. That means it can be a risk to your health and the environment.

How to collect stormwater safely

  • Only capture stormwater within your property’s boundary.
  • Keep your property clean – for example, no loose soil or chemical spills.
  • Only use stormwater for purposes such as garden watering and toilet flushing.
  • Never use stormwater for drinking or food preparation.
  • Only use a licensed plumber to install a stormwater system.

How to use stormwater

There are no Regulations for stormwater use in Victoria. However, there may be Regulations on the right to harvest stormwater and construct stormwater schemes.
