The problem is that, in Australia, many toilets are connected to the stormwater system. This means that any toilet waste is washed into the stormwater system and this can end up polluting our water and causing the spread of diseases. This is why it is important to have a septic tank to remove any toilet waste from your home.You can make sure that you don't add liquid waste to your stormwater runoff by not cleaning your car at the kerb, sweeping, hosing the driveway, or washing your car in the driveway. These actions all create solid waste that goes to your kerb drain which then goes to your stormwater system.
