The Water Authority of Fiji (WAF) has successfully eliminated discoloured water to customers in Nadi and Lautoka in the Western Division.

Earlier this month, WAF had detected an increase of Iron (Fe) and Manganese (Mn) levels at the Nagado Water Treat­ment Plant from raw water sourced from the Vaturu Dam.

This was because of sudden changes in climatic condi­tions resulting in low dissolved oxygen levels at the Dam.

WAF general manager customer services, Sekove Ului­nayau said that the oxidation reactions of iron and man­ganese had caused the water in the Nadi and Lautoka wa­ter system which is fed from the Nagado Water Treatment Plant to appear discoloured (pale to brownish).

Mr Uluinayau said that the Authority had reduced the lev­els of iron and manganese at Vaturu and Nagado through consistent aeration.

“WAF had 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 where we are also applying pre and post chlorination at the plant as well as regular flush­ing of the reticulation system,” Mr Uluinayau said.

Mr Uluinayau also said that the preliminary costs on rec­tifying the discoloured water is over $100,000 so far, and it is expected to increase as aeration is still in place both at the Vaturu Dam and at the Nagado Water Treatment Plant.

“For majority of the residents in the whole Lautoka and parts of Nadi, water appearance in taps has improved and should no longer be discoloured. Our crew members have been continuously conducting flush out works to re­move all discolored water in the ex­treme end of the re­ticulation system,” said Mr Uluinayau.

Mr Uluinayau said that WAF is com­mitted to improv­ing water supply around the country and apologizes for the inconvenience caused.

Meanwhile, customers around Nadi and Lautoka are to contact the Water Authority of Fiji on 5777 or 334 6777 or email contact@waf.com.fj if they continue to receive discol­oured water in their taps.
