Water update for Gisborne customers

23 January 2020

We’ve recently had some feedback from customers mentioning issues with odour in their water supply. We’d like to thank you for your patience while we have been looking into the issue.

Firstly, we can assure you that the water at Gisborne is safe to drink and well within the Australian Drinking Water Guideline (ADWG) standards.

The earthy smell reported by some customers is caused by the harmless, natural occurring compounds Geosmin and Methyl-Isoborneol (MIB). They are often found in all water sources, however under certain climate conditions, the ‘earthy’ smell they cause can be more noticeable.

Over the last few weeks we have had high variability in weather – very hot days, heavy rain, cool days. This has increased Geosmin and MIB.levels.  In response to customer feedback we’ve implemented the maximum level treatment processes that are currently available to us.

Some customers have asked us to switch supply to the Melbourne system. This system is unable to keep up with the current peak demand in the region and if we switched it would require Gisborne residents to comply with water restrictions.

We anticipate this issue is temporary.

 Any issues related to discoloured water are completely unrelated to this issue.
Please call our team on 1300 650 422 to discuss any water quality issues.
