But the authority has reassured residents the water remains safe.
“Some customers may notice a slight change in the taste and odour of the drinking water,” managing director Andrew Jeffers said.
“(However) our treatment process ensures that the water supplied from the Warrnambool treatment plant is perfectly safe to drink.”
He said the warmer months made managing the drinking water supply “challenging”, despite the high quality of Warrnambool’s sources.
“Algae thrive in warm, sunny conditions and it is not uncommon to see taste and odour-causing algae develop in water storages from Spring onwards, not just in Warrnambool but right across Victoria,” Mr Jeffers said.
“Many customers won’t notice any change at all.”
He said the discovery of algae was made during Wannon Water’s regular water testing.
Wannon Water will be taking “the affected water storage offline” for treatment, increasing its water testing, and flushing sections of the network.
