About 150,000 people living in Fiji's Nadi and Lautoka area are being told to store water as they will be impacted by a major shutdown next month.
The planned water disruption is a result of a broken control valve and leaking pipes that need urgent repairs at a plant in Nadi.
The Water Authority says the system will be down for four days from February the 3rd.
The FBC News reports a month's notice has been given to residents to help them prepare for the disruption although the WAF Board Director Kamal Gounder says around 100 water tanks will be provided and placed in strategic locations.
The Authority said it would ensure that during the shutdown there would be no interruption in services to facilities such as hospitals, airports, schools and hotels.
The Authority said although the repair was of a minor leak it was developing and had been observed for a couple of months and if it further developed it could trigger a major disaster.
The island of Viti Levu has been plagued with supply issues for a while and last year the Parliamentary Opposition called for an investigation into water issues in the urban centres.
