Severe weather conditions may impact the network

Due to severe weather conditions forecasted from today, 30 April until Friday 2 May, there may be impacts on the network, 

Heavy rain increases the chance of excess stormwater entering the wastewater network, which it doesn’t have capacity for. This means there is a higher risk of wastewater overflows during wet weather events or emergencies such as major power cuts.

Our operations team are checking known risk areas and working to ensure that the stormwater network will be running as smoothly as possible.
