A treatment plant operating correctly and being maintained as detailed by the manufacturere should produce an odour free aerobic bacteria. However, there could be times when some odour may be detected but when compared to a septic tank system these odours are likely to be weak.

The majority of systems that we are called to investigate have smell problems due to lack of correct maintenance and de-sludging. The majority of treatment plants require some form of de-sludging.
