Check your downpipe connections and ORG - ensure they are in good condition and make sure that stormwater is able to run off away from your property without being channelled into the sewer.
Make sure the ORG is correctly installed - ensure the area surrounding your ORG is sloped away from the house. This directs sewage flowing from the ORG away from your home and helps prevent stormwater from entering it ensuring the ORG is raised above ground level to prevent water entering.
Check the height of your ORG
When the ORG is surrounded by grass it must be 75mm above ground level.
If the ORG is raised too high it may be above floor level and, in the event of a blockage, sewage in the sanitary drains may back up and overflow out of floor wastes inside the house.
If the ORG cannot be raised to its correct height, an inflow prevention device may need to be fitted to it.
Prevent stormwater entering the sewerage system on your property by:
never covering or obstructing sewer maintenance holes or ORGs
never planting trees over or around sewer lines
never connecting stormwater downpipes to your property’s ORG or sewer pipes
ensuring your property’s stormwater downpipes drain roof water a minimum of one metre away from your house
ensuring any broken water pipes on your property are repaired immediately
ensuring your home’s internal drainage pipes are in good condition.
If we find an illegal or inappropriate stormwater-to-sewer connection on your property’s drainage system, you will be issued with a notice to call a licensed plumber/drainer to correct the defect within 28 days.
