WAF works to end water disruptions

Update: 4:10PM THE Water Authority of Fiji has apologised to customers living in some parts of Suva-Nausori area and in surrounding Labasa areas who had been facing water disruptions for the past few weeks.
WAF has attributed disruptions between the Suva-Nausori corridor to extensive repair works undertaken to filters at WAF’s Waila Water Treatment Plant in Nausori.
As a result, some residents have been facing intermittent supply and low water pressure, which WAF says will continue for the next few days.
WAF board director Kamal Gounder said the low water levels were a result of the recent adverse raw water quality that had affected the filtration rate at the water treatment plant.
He said this followed a week of water disruptions attributed to the electrical failure at the Waila Water Treatment Plant, which was a result of a damaged cable between the raw water intake and the treatment plant.
“This was rectified and water treatment is back to normalcy. However, WAF is still facing an additional challenge at the Waila Water Treatment Plant where the plant has been receiving a high level of silt in the clear media filters,” Mr Gounder said in a statement.
“The amount of silt coming through the raw water pumping stations in Waimanu and Savura has also resulted in a high organic matter concentration in the raw water filters at the Tamavua water treatment plant, also contributing to the filters being clogged during the recent dry weather.”
In Labasa, Mr Gounder said the low water supply there was partially disrupted because of a pipe burst that occurred under the river at Dogoru.
He said this was rectified by laying a new pipe under the river and water supply was back to normal.
Mr Gounder said WAF had developed a risk register for each treatment plant and they were now working on measures in implementing this.
Major improvements identified as per the risk register included treatment capacity upgrades, electrical and mechanical upgrades, intake improvements, providing standby generators for all pumping stations, replacement of aged valves and improvements at river crossings like having duplicated lines.
