Rainfall levels

Rainfall levels have an impact on water supply. Enough rainfall during wetter months replenishes rivers, reservoirs and aquifers for use in dryer months. However, exceptionally high levels of rainfall, especially over a short period of time, can cause flooding and increases the volume of wastewater that needs to be managed. This can overwhelm our system and result in storm overflows.

At the other end of the scale, too little rainfall can lead to droughts and shortages of water supply. Together, we can do our bit to save water and make sure there is enough to go around when rainfall levels drop across our region.
