The Flora Street Wastewater Pump Station had been causing odour issues for the Water Corporation of Western Australia for many years. Despite large land buffers around the pump station, the age of the station and the leaky sewer infrastructure in the nearby area meant that sealing the upstream wastewater collection system to prevent pressurised foul air being released into the atmosphere was near impossible.
Hydrogen Sulphide measurements taken within the wet well showed an average of 182ppm and maximum of 316ppm – highly concentrated and likely to be causing corrosion of sewer infrastructure in addition to the ongoing odour issues. As complaints from nearby residents continued, OdaTech was contracted to design, manufacture and install an odour control facility which would ensure that the issue was resolved.
The odour control system, completed in June 2015, was designed to not only treat the foul air extracted from the wet well, but also to keep the upstream collection sewer mains under negative pressure so that air would not escape from nearby access covers and manholes, a number of which were also located on the site.
Since the system has been installed, loggers have recorded zero H2S at the treated air outlet, but in addition to that, average hydrogen sulphide within the wet well has dropped from an average of 182 to 20 ppm – significantly reducing the risk of corrosion damage within the sewerage infrastructure.

Ivan and the OdaTech team promised to stop the odour from our smelly neighbour and they delivered- in spades! As soon as the system was started, the smell disappeared. The system is well designed, very professionally installed and the beauty of it is, apart from a constantly running fan, it is bacteria doing the heavy lifting, so it is very environmentally friendly. We lived with the smell for 3 three years which could be extremely frustrating and unpleasant. Now, the problem is solved and we can have BBQs again. We are happy and our neighbours have noticed the odour is gone. Thank you!
OdaTech has installed more than fifty such odour control systems across Australia and are happy to custom design a system for any size and footprint – contact us for a quote.
