A South Coast council is using smoke for a good cause.

A Bega Valley Shire Council (BVSC) spokesperson said a sewer and stormwater smoke testing program would be carried out in Merimbula to ensure the town’s sewerage network remained intact.

“Smoke testing is a cost-effective method to pinpoint issues within Council’s sewerage network, including non-compliant stormwater connections,” they said.

“Contractors introduce non-toxic smoke into the sewer system, which emerges at locations with potential problems like cracked pipes and failing seals.

“Testing also detects smoke coming from residential stormwater infrastructure such as downpipes and gully traps.”

The smoke used is non-toxic, non-staining and odourless. It will not enter homes with a functional plumbing system.

However, the BVSC spokesperson recommends that people with respiratory conditions – such as chronic asthma and emphysema – should avoid direct exposure as a precaution.

The presence of smoke may indicate a non-compliant household connection to the sewer system, adding significant pressure to the infrastructure.

“During heavy rain, sewerage infrastructure can become overwhelmed if stormwater enters the system,” the spokesperson said.

“Sewer spills from an overstressed system can threaten our marine and lake industries and significantly impact surrounding environments and waterways.

“If a non-compliant connection is found, property owners will be contacted with details on how to rectify the issue.”

Smoke testing started on Tuesday (11 June) and will continue throughout June in the Merimbula area.

Affected residents will be notified via a letterbox drop and do not need to take any steps to prepare.

Under the NSW Local Government Act, a property owner is responsible for fixing any problematic connections, even if they are unaware of them.
