Stormwater drains are needed to prevent flooding

Have you ever wondered what happens to all the water when it rains? In our towns and cities much of the ground is covered by buildings, roads and paths. There is not enough uncovered soil to soak up the water.

Cities and towns have an underground network of stormwater drains. These drains are connected to the gutters along the roads and to the downpipes leading down from the roofs of our homes and buildings.

Rainwater flows from our roofs and the gutters along the road into the stormwater drains. The stormwater drainage system is designed to prevent our streets and homes from flooding.  

The stormwater drains slope downhill and all eventually empty directly into the sea, creeks, rivers or other natural or artificial wetlands.
