WAF resolves issue of discolored water supply to residents in parts of Nadi and Lautoka

Water Authority of Fiji has successfully resolved the issue of discolored water supply to residents in parts of Nadi and Lautoka.

Water Authority of Fiji General Manager Customer Services Sekove Uluinayau has revealed that the oxidation reactions of iron and manganese had caused the water in the Nadi and Lautoka water system which is supplied from the Nagado Water Treatment Plant to appear discolored.

He says this was due to sudden changes in climatic conditions resulting in low dissolved oxygen levels at the Dam adding that the Authority has reduced the levels of iron and manganese at Vaturu and Nagado through consistent aeration.

Uluinayau says that the preliminary costs of resolving the issue of discolored water was over $100,000 and it is expected to increase as aeration works are still in place both at the Vaturu Dam and at the Nagado Water Treatment Plant.

Sekove says that Water Authority have installed aeration systems to pump in oxygen to decrease the levels of iron and manganese at the water source in the Vaturu Dam and at the Nagado Water Treatment Plant’s inlet chamber.

He says for majority of the residents in the whole Lautoka and parts of Nadi, water appearance in taps has improved and should no longer be discolored.
