Check your downpipes

When it rains heavily, too much stormwater entering the wastewater network can cause the sewer to overflow.

That’s why it’s important to make sure your stormwater pipes are connected correctly to the wastewater system. Incorrectly connected pipes can lead to sewage overflows on your property or elsewhere in the network, affecting homes, businesses and the environment.

Everyone in the community plays a part in preventing stormwater from entering the wastewater network.

How do I know if my stormwater pipes are connected correctly?

If you are not sure whether your stormwater pipework is connected properly, contact a licensed plumber for advice.

How to prevent stormwater entering the wastewater system?

If there’s a sewer manhole on your property, it must be clear of obstructions and accessible.

To help protect the wastewater network and prevent sewer overflows:

  • Do not connect stormwater downpipes to your internal sewer pipes or overflow relief gully
  • Repair broken pipes as soon as possible.
  • Keep internal sewer and stormwater pipes in good condition.
  • Avoid planting trees too close to sewer pipework. Tree roots can cause cracks and let groundwater in.

Do I have, or know of, an illegal stormwater connection?

If you suspect an illegal connection to stormwater, contact us.

We’ll work with you to offer advice and help you fix the issue.

What happens during wet weather?

During heavy rain, the wastewater network can become overwhelmed by excess stormwater, especially if downpipes or other stormwater systems are not connected properly.

This increases the risk of sewer overflows, which can damage homes, harm the environment and impact community health.
