Stop sewer problems occurring

Here are some simple things you can do inside and outside your home to prevent sewer problems occurring in the future.

Some tips for inside

We treat wastewater from over 250,000 properties in the lower Hunter, so what you do and don’t flush down the toilet, drain or sink can make a big difference.

Respect the Throne

In the toilet, help keep the pipes free, only flush toilet paper, poo or pee.

Wiping with anything else? bag it and bin it.

Other products like tissues, paper towel and wet wipes don’t break down properly and can cause large blockages in our wastewater system that are expensive to remove.

Sewer blockages are horrible and unpleasant for our crews to remove, and they can cause overflows into our waterways and even people’s homes, leading to costly plumbing bills for the homeowner.

If you need to use products other than toilet paper, they should be disposed of in the bin.

The wrong type of items can block your drains, overload and damage the wastewater system or create environmental damage.

What you can't put down the toilet, drain or sink

Wipes, paper towel, nappies and sanitary products

Fruit and vegetable waste

Cooking oils and fats

Dairy products

Pills and medicines

Household paint and cleaners

Chemicals, pesticides, motor oils

Stormwater and yard drainage

Cosmetics and cotton buds

Some tips for outside

In each household, it is up to the property owner to maintain and repair sewer (wastewater) pipes and fittings inside the property through to the point of connection with our wastewater system. If you identify any sewer overflows on public land, like the road or footpath, please contact us immediately.

It is good practice to regularly check and maintain your plumbing, and also be aware of the location of your pipes when planting or digging in your garden. Here's how.

Check your downpipes

During periods of wet weather and in instances where large volumes of stormwater may enter the wastewater network, sewer overflows can result.
