Activity Introduction

Quick summary: Students use a map to show locations where their school is connected to the stormwater at ground level. They collect data about what polluting substances might be carried along with rain into the stormwater system.

Learning goals:

  • Students show locations on a map of open stormwater entrances into the stormwater system.
  • Students collect data about polluting substances that can be washed into stormwater systems after rain.
  • Students identify the most common substances that cause stormwater pollution.
  • Students will identify the most significant materials and other substances in the school ground that are likely to cause stormwater pollution.

Introduction

Stormwater drains are essential for removing rainwater quickly and in large volumes so our towns, suburbs, industrial and other built areas aren’t flooded after rain. The stormwater drains eventually empty into waterways which include lakes, rivers and the sea. In newer suburbs and where areas are available, stormwater may go into stormwater ponds where nature can extract some of the nutrients before it goes into the waterways. Also litter traps are often installed to prevent litter reaching the waterways.

The most common sources of pollution entering stormwater are:

  • All types of litter
  • Over flow from private septic tanks
  • Dissolved dog droppings
  • Leaves and other garden material
  • Soil and dirt
  • Oil from dripping car engines and gear boxes
  • Fertiliser and insect spray
  • People washing paint brushes into the drains
  • People pouring chemicals and other liquid waste down drains.
