Extensive stormwater inflow into the sewerage system at Innisfail, Tully and Mission Beach is causing problems with a significant proportion exceeding their capacity and some sewers are overflowing.
Over the next few months, Council will be investigating the sewer network to identify where rainwater is entering the sewers. Besides eliminating the nuisance of overflows, removing excessive stormwater in the Council sewerage systems will reduce operating costs.
The sewage (and stormwater) is pumped multiple times before it gets to our treatment plant so reducing the stormwater component saves on pumping and treatment costs. As part of our investigations we will be using smoke testing, which is an efficient, cost-effective way to locate faulty sewers and plumbing.
