The Water Authority of Fiji is considering the hiring of overseas expertise to remove silt from the bottom of the Vaturu Dam in Nadi.

According to chief executive fficer Opetaia Ravai the bottom of the Vaturu Dam had not been cleared since its commissioning in 1983.

“The silt at the bottom of the Vaturu Dam is thick and urgently needs clearing. We are going abroad to get experts to assist us on this,” Mr Ravai said.

Meanwhile, over 600,000 litres of water were being carted to certain areas in Nadi as algae continue to cause blockage of filters at the Nagado Water Treatment Plant.

Yesterday, Mr Ravai showed the filter section and the Vaturu Dam catchment area with water receding due to lack of rainfall.

Twenty-three trucks, some from Suva, have been filling water from a station set up at Lomolomo Village, between Lautoka and Nadi.

Mr Ravai said their operation was advanced in that they could tell which areas in Nadi were about to get less water by the drop of water levels at the dams for these areas.

However, he said the situation was not critical but advised consumers to use water wisely.

What began as a disruption to water production at the Nagado Water Treatment Plant through damage to its filtration system last Thursday has been significantly challenged with the introduction of a high level of algae flowing into Nagado from its source, Vaturu Dam.

“What has happened has never happened before, the combination of conditions that are required to grow algae, a harmless, miniature, but prolific type of plant similar to seaweed that has literally grown to significant proportions in the waters of the dam,” said Mr Ravai.

He said initially the filtration system was damaged by normal wear and tear, but the sudden “high” flow of algae, had slowed up the system and reduced the amount of treated water filtering through.

Mr Ravai confirmed that it could take up to two months before water supply in affected areas were normalised.

 

Areas affected include:

The general Votualevu area from Tadra Road, ATS, Savunawai right up to CAAF compound, the Holika areas, Nadele from Thompson Road up to the Sleeping Giants, Lolobalavu areas and along Nadi Back Road, Solovi areas, Nasau from SSS Hotel right up to Mulomulo Village and Nagado areas such as Malolo, Navo, Tunalia, Nacovi, Sonaisali, Malamala, Nawaicoba, Yako, Nabila, Fiji Marriot Momi Bay Resort, and Uciwai.
