Blackwater events happen when too much carbon is in the water. This can be caused by leaves, branches and other organic material washing into the river as the water level rises.
The release of carbon compounds including tannins contributes to the black appearance of the water. Manganese can be released from the riverbed as well, which contributes to discolouration of the water.
During a blackwater event, LMW staff closely monitor and continuously fine tune the treatment processes at our water treatment plants to improve the clarity and taste challenges blackwater causes.
The town treated water is generally safe to drink however may be discoloured. Raw river water may cause discolouration to clothing during washing. Blackwater may also cause filtration problems for irrigators.
