The completion of a 650metre, under-sea, pipeline that connects Vio Island with the Water Authority of Fiji (WAF) Lautoka Depot means that the island’s 230 residents now have access to a better and consistent water supply.
WAF was engaged by the Prime Minister’s Office to initiate this project, following the request for assistance made by the people of Vio Island to the Prime Minister’s Office.
The 50.5mm water pipeline was launched from the WAF Lautoka Depot seawall on 2nd June this year after the pipeline joints had been welded together by electro-fusion.
The pipeline was floated out to its full length before being pulled across to Vio Island, and then sunk to avoid any disruption to the shipping lane.
Previously constructed, custom-made top and bottom concrete blocks were installed as anchor blocks, every 6.0 metres along the submerged pipeline. Each pair of anchor blocks weighs 30kg and is held together by large cable ties around the water pipe.
The submarine pipe works were outsourced to Dive Centre (Fiji) Limited.
As well as the laying of the submarine 50mm polyethylene pipeline, the $104,617 project saw the installation and chambering of an air valve and master meter, and the laying of the 100mm PVC pipeline works from the WAF Depot at Vetari to the foreshore.
On Vio Island, WAF crew members laid DN100 PVC mains and installed five 10,000litre, elevated water tanks.
According to WAF’s General Manager for Planning, Design and Construction, Mr Nemani Waqanivalu, the villagers rejoiced with a small celebration when water supply reached the island at 3pm on Friday, 8th June. He said that nearly all households on the island are receiving water through their taps at home.
WAF Chief Operating Officer, Mr Samanmal Ekanayake, said WAF would continue to implement works that ensure Fijians have access to safe drinking water and proper sanitation.
Mr Ekanayake said the villagers now enjoy a consistent supply of water that should withstand dry seasons, and an improved, water system performance.
