Technical Leader – Odour Management
Stantec Australia Pty Ltd

As Technical Leader for Odour Management, Ian Evanson measures success by smell.

Ian boasts an impressive suite of involvement in more than 74 projects over a 22-year career, 13 with Stantec, which spans the odour control, wastewater design and gas scrubbing industries in Australia, the UK and Middle East.

Ian enjoys working in the wastewater industry, and gets a boost fixing odour problems that naturally occur with treatment plants, and improving people’s quality of life in the process.

One of Ian’s highlights was during the Oxley Wastewater Treatment Plant Project in 2006 where his biggest aim was to stop the stench. At the final community meeting Ian received the best client feedback ever – the group said they were delighted they couldn’t smell the plant anymore.
