GWIG Membership

We are always keen to have new members come on board to help support and grow this important industry. Membership will allow you to both meet like-minded professionals and keep up to date with the latest developments in the water and wastewater business.

Our annual membership gives great value for money as we are a not-for-profit organisation with no overheads. Our members give generously of their spare time and you are most welcome to apply for a position on our organising committee. We typically meet monthly.

If you are interested in becoming a member of GWIG please contact one of our committee members to request a membership application form or download it below. Please email completed application form to Stewart Dallas, for consideration. Please include a brief summary of your involvement with wastewater to date. A copy of your company logo (if applicable) will be required in due course for the GWIG website.

Annual dues for membership are currently $100 for the year, 1 July 2018 – 30 June 2019. Fees are not calculated on a pro-rata basis.
