An inspection program using smoke tests will start today to identify the sources of stormwater and groundwater leaking into the Hervey Bay sewerage network.
“As part of the inspection program, smoke will be injected into the sewerage lines to identify leaks or illegal connections,” Fraser Coast Regional Coast Cr David Lee said.
“Leaks can allow groundwater to enter the sewerage system. Illegal connections channel stormwater straight from rooves into the sewerage system.
“During storms, the amount of sewage heading to the treatment plant can be more than five times expected dry weather flows.
“That extra water needs treating, which costs ratepayers money. It can cause the treatment plants to overload and hurt the environment.”
As part of the inspection program, staff will inject a non-toxic, non-staining, odourless coloured smoke into the sewers.
“We are looking for places where the smoke escapes. It should be from cracks in pipes or incorrectly installed stormwater drains. That way, we can see faults that need fixing,” Cr Lee said.
“Smoke may emerge from yards, roof gutters, pipes or street drains. It is also possible that smoke may appear inside a house if the drainage traps are dry.
“The smoke from the smoke tests is not flammable and will not cause any harm to people, pets or plants.”
Cr Lee said the discovery of properties with illegal connections would not necessarily receive fines.
“Our experience is that once made aware of issues, most property owners comply with the request to rectify problems,” he said.
Residents will be notified of the timing of inspections.
The inspection program is due to run from Monday, November 1 to 16.
Inspection programs for Eli Waters and Howard will start in early 2023.
