Stop sewer problems before they start

What goes down your toilet, sink or drain can have a big impact on the entire Hunter Water network.

Hunter Water treats sewage from over 250,000 properties across the Lower Hunter and when the wrong things end up in the pipes, it can cause problems for your home and our network.

These items can block your drains, overload or damage the sewerage system and even harm the environment.

Sewer blockages can cause sewage to overflow into homes and waterways, leading to expensive plumbing bills for homeowners and an unpleasant job for our crews to clean up.

Help keep sewer pipes clear

Did you know there are only three things you should flush down the toilet?

Everything else?

Bag it and bin it to help keep the pipes flowing freely.

Looking after your sewer pipes

As a property owner, you are responsible for maintaining, repairing and replacing the sewer (wastewater) pipes and fittings on your property, right up to where they connect with Hunter Water’s wastewater system.

This includes the boundary trap and inspection shaft.

How to keep your pipes in good shape

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.

Is your overflow relief gully overflowing?

If there’s a sewer blockage, the overflow relief gully grate is designed to pop off, releasing pressure and directing sewage safely away from your home.

If this is happening, do not forget to check your sewer shaft too.

Check before you dig
