Prolonged dry conditions and warm weather in the Murray River catchment area is resulting in poor raw water quality in the Coliban Water Murray Supply System.
The Murray Supply System supplies the townships of Echuca, Leitchville, Gunbower and Cohuna.
Manager Community Operations Mick Dunne said there are no health risks associated with the drinking water.
“It is safe for all drinking, bathing and food preparation purposes and the water being supplied continues to comply with all health-based guideline values in the Australian Drinking Water Guidelines.
“The reduced quality of the raw water is a result of high concentrations of naturally occurring taste and odour compounds being present in the raw water supply. Blue Green Algae blooms can cause these compounds to be more present.
“Treatment measures are in place at the water treatment plants to minimise the impact to the drinking water supply for these towns. However, customers may be experiencing a change to their drinking water; with the water having an earthy taste and smell as a result.
“Further works are being investigated at all four locations to ensure water treatment processes are being optimised to minimise any taste and odour impact to our customers. However, until raw water quality improves we are unable to completely remove the taste and odour compounds,” Mr Dunne said.
“We are aware that this has been an inconvenience for our customers and we are working hard with water quality specialists and operational teams to improve the supply,” Mr Dunne said.
The corporation said the regions changing climate conditions is resulting in higher concentrations of algae and extended periods of blooms in local water bodies.
“We are noticing an increase in the intensity and duration of Blue Green Algae (BGA) blooms across many of our water sources with a changing climate, particularly in the River Murray and associated channels, where there have been significant blooms over the last few years.
“Managing the increased risk of BGA blooms is part of our climate adaptation considerations in our Strategy 2030 strategic plan,” Mr Dunne said.
