Incorrect stormwater connections
Every time it rains, our sewerage network is under threat from sewage overflows caused by incorrect stormwater connections.
Stormwater is rainwater that runs off surfaces such as lawns, roads, roofs, carparks and natural ground surfaces.
Know your water types and send it down the right pipes
Stormwater and sewage do not mix! It is illegal to direct stormwater or rainwater into the sewerage system via your Overflow Relief Gully (ORG). The ORG is the drain-like feature with a grated lid that can be found in the ground outside your home.
Our sewerage network is designed and operated to convey five times of the average dry weather flow. Excessive stormwater inflow that exceeds the capacity of the network puts sewerage pipes and pumps under immense pressure.
With nowhere else to go, sewage can back up and overflow from controlled spill points or less frequently, from maintenance holes or private property.
By detecting and fixing any points on your property where stormwater may enter the sewer, you will be doing your part to protect your property, neighbourhood and the environment against wet weather sewage overflows.
All your stormwater must flow to a rainwater tank, the road kerb or a stormwater pit. Occasionally, it may be plumbed directly to the underground stormwater system where the discharge cannot be seen. This may be the case when the street is higher than your house and there is no grated stormwater pit in your backyard.
If you think your stormwater pipes are connected to the sewerage system, please have them inspected by a licensed plumber.
Refrain from discharging pool water to the sewer directly after a rain event. Check where possible that only backwash water enters the sewer. Some pools have a valve that can be set to divert backwash water to the sewer and overflow water to the stormwater system.
Your ORG is an important part of the sewerage system that directs sewage overflows outside your home, rather than inside your home.
It is not a stormwater drain. Your ORG should have a loose, grated lid and can be found on the ground outside your home. It is connected to the main sewerage drain to stop sewage entering the house when an overflow occurs.
Rain-Dependent Inflow Management Pilot
The City is undertaking a Rain-Dependent Inflow Management Pilot to determine suitable methods of investigation and remediation of stormwater inflow points.
Selected areas of Nerang, Pimpama, Burleigh Heads and Helensvale will be investigated. These areas suffer from excessive stormwater inflow and/or repeated wet weather sewage overflows that pose elevated risks to public health and the environment.
The City inspects, repairs and maintains Council-owned sewers. Meanwhile, property owners are responsible to ensure the sewerage and stormwater pipes within their property boundary are compliant.
Within the selected areas, the City will undertake an Approved Inspection Program that allows Authorised Persons to enter and inspect properties to ensure compliance with legislation. The purpose of this program is to improve the level of compliance of private sewerage plumbing to reduce excessive stormwater inflow and mitigate wet weather sewage overflows.
The program will run from 1 October 2018 to 31 December 2018.

Managing wastewater is a partnership
The City inspects, maintains and repairs Council-owned sewers. Meanwhile, as the property owner, you are responsible for ensuring that stormwater and sewerage pipes within your property boundary are compliant.
The faults of your property may seem minor, but the combined volume of stormwater into the sewerage network is significant. If everyone does their part to repair the faults in their property, we can reduce the amount of stormwater inflow and protect our homes and waterways from sewage overflows.
