Manholes and sewer overflows
-
What is a sewer manhole?
Sewer manholes are access points to the underground wastewater system. They let us inspect, clean and maintain the sewer network.
You will often see them in roads, footpaths, public spaces and sometimes on private property.
We may need to access manholes on private property under our Customer Contract and Operating Licence obligations.
-
What is a sewer overflow?
A sewer overflow happens when wastewater escapes from a sewer manhole or within a property, usually because of a blockage in the system.
This can cause sewage to back up and overflow onto roads, footpaths or private property.
Report overflows immediately so Hunter Water can act quickly to fix the problem.
-
Is a manhole overflow always sewage?
Yes, because manholes are part of the underground sewer network, not the stormwater system.
If you see water or waste coming from a manhole, it’s likely a sewer overflow and should be reported straight away.

What’s the difference between a sewer manhole and a stormwater drain?
Sewer manholes
Are sealed, flat metal covers that sit level with the ground.
They allow access to underground sewer pipes.
If you see waste or dirty water coming from a manhole, it usually means there’s a blockage or backup.
Call us on 1300 657 000 immediately.
Stormwater drains
Are grated openings usually found on roadsides or in gutters.
They carry rainwater into local waterways, not the sewer, so it is normal for them to overflow in heavy rain.
There’s no need to make a report.
Have you experienced damage to your property?
We work hard to minimise property damage for our customers. But sometimes a water main breaks or a sewer overflows, causing damage.
