Episode: Water and waterways
Hard surfaces like roads and footpaths in our cities stop rain from soaking into the ground. This water must go somewhere, and a network of stormwater pipes has been built across our cities to remove this excess water when it rains.
Stormwater pipes are different to the pipes in our homes. When it rains, water in our streets flows into stormwater drains, along with any rubbish or pollutants in the street.
