Water supply in Rakiraki has now been fully restored, however, restoration works are continuing in Lautoka, Tavua, Ba and Sigatoka, with desilting, infrastructure repairs and system stabilisation still underway.
Minister for Public Works Ro Filipe Tuisawau says the severe weather brought intense rain across several water catchments.
He says this resulted in extremely high turbidity levels, meaning large amounts of mud and debris in raw water sources, along with intake blockages, flooding of pump stations and damage to raw water pipelines.
These conditions temporarily disrupted water production and supply in parts of the Western, Central and Northern Divisions.
Ro Filipe says during extreme rainfall, rivers and water sources can experience very high turbidity levels caused by sediment and debris being washed into catchments.
He says this makes it more difficult for treatment plants to produce safe drinking water and can temporarily reduce production while systems stabilise.
The Minister says the Government has been closely monitoring the situation and working with the Water Authority of Fiji to ensure restoration continues as quickly and safely as possible.
Following the cyclone, Water Authority teams were immediately mobilised to clear debris, repair damaged infrastructure, restore pump station operations and stabilise treatment plants.
He says the Western Division experienced some of the most significant impacts, particularly in Ba, Tavua, Rakiraki, Lautoka and Sigatoka.
In the Central Division, prolonged rain increased turbidity levels in the Tamavua catchment, temporarily reducing production at the Tamavua Water Treatment Plant.
Production levels are now steadily recovering.
Localised disruptions were also experienced in parts of the Northern Division, with restoration works continuing to maintain stable operations.
Ro Filipe has thanked members of the public for their patience and understanding while restoration works continue.
The Government says it will continue to monitor progress closely until all affected water supply systems return to normal operations.
