A smoke test is being conducted in Mount Forest this month to identify weak spots in the sewer system where rain water is entering.
Wellington North, in partnership with Cole Engineering Group Ltd is working on the month long inflow and infiltration reduction study.
The sanitary sewer system collects wastewater produced by houses, business and industries, directing it to the treatment plant. Infiltrations occurs when rain and ground water enters the sewers through cracks or holes in the pipes. This causes increased volume at the treatment plant, reducing the capacity.
The smoke test, which blows harmless coloured vapour into the sewers, will be able to identify those weak spots. The smoke has no odour and is not harmful, said the township in a release.
The township stated the smoke is expected to exit primarily out of manholes and sewer plumbing stacks on top of houses. The smoke can also exit stormwater catch basis and downspouts.
Residents in testing areas are expected to receive fact sheets prior to the testing.
