The change in taste and odour is due to an increase in naturally occurring organic compounds known as MIB (Methylisoborneol) and Geosmin in the raw water supply to Seqwater’s Lowood Water Treatment Plant. These naturally occurring compounds are due to increased algal levels in the raw water which has bloomed due to recent weather conditions.
We can assure residents the treated water supplied from Lowood Water Treatment plant remains safe to drink and use as normal. Though algae is filtered out through the water treatment process, it can leave behind these taste and odour compounds that can cause the treated water to temporarily taste and smell earthy or grassy.
Sensitivity to taste varies from person to person, so some people may not notice any change while others will. Cooling the water can help reduce any earthy taste in the tap water.
Seqwater is undertaking increased monitoring of the water catchment and throughout the treatment processes, and taking steps to reduce the change as much as possible.
Urban Utilities will continue working closely with Seqwater to keep customers updated.
The water will return to its usual taste and odour, however it may take some time pending weather conditions.
Tap water is constantly monitored and rigorously tested to ensure it meets the stringent health requirements of the Australian Drinking Water Guidelines.
