Problems can occur when stormwater runs into the sewerage system. The integrity of sewers is often compromised by illegal stormwater connections, faulty joints, tree roots cracking pipes, redevelopment of property and age.
Stormwater infiltration into the sewer during and following rainfall events can cause the sewerage system to have too much water and to discharge through designed overflow points in creeks and stormwater drains.
