WAF improves water quality in Nadi and Lautoka
November 30, 2018 2:10 am
The Water Authority has successfully eliminated discolored water to its customers in Nadi and Lautoka.
Earlier this month, WAF had detected an increase of iron and manganese levels at the Nagado water treatment plant from raw water sourced from the Vaturu Dam – this is due to sudden changes in climatic conditions resulting in low dissolved oxygen levels at the Dam.
WAF General Manager Customer Services, Sekove Uluinayau says that the oxidation reactions of iron and manganese caused the water in the Nadi and Lautoka water system to appear discolored.
Uluinayau says they have reduced the levels of iron and manganese at Vaturu and Nagado through consistent aeration.
He adds the preliminary costs on rectifying the discolored water is over $100,000 so far, and it’s expected to increase as aeration is still in place both at the Vaturu Dam and at the Nagado Water Treatment Plant.
WAF crew members are continuously conducting flush out works to remove all discolored water in the extreme end of the reticulation system.
