ABOUT 161,000 Lautoka and Nadi residents will be without water for 48 hours this weekend, says the Water Authority of Fiji.
WAF said work would be carried out to repair three major leaks in the high pressure main from Vaturu to the Nagado treatment plant.
"Alongside this, installation of isolation valves will be done to improve hydraulics," WAF said.
"These works are expected to decrease water loss via leaks.
"The duration of works will be from 10pm Friday to 10pm Sunday. The areas affected will be all of Nadi and some parts of Lautoka."
WAF has advised customers in the affected areas to store water for their immediate needs and not rely solely on water trucks.
Residents have also been urged to use water sparingly.
The non-affected areas include Lautoka City, except high residences along Loma Lane, Lautoka Hospital, Waiyavi Stage 5, MT Khan, Mendhi Place, Vitogo Paipai, Naikabula, Tomuka, Matawalu, Johnson, Drasa Dam, Ajan Rd, Qalitu, Vitogo Koro, Naviyago Koro, Vunato and Buabua.
