The Water Authority of Fiji says following the heavy rain experienced yesterday, both the Savura and Waimanu Raw Water Pump Stations are impacted and offline.
In a video statement, WAF Chief Operating Officer, Seru Soderberg said that water levels at the Waimanu and Savura Plants are still high, and their divers cannot safely dive with visibility underwater less than a foot which makes clearing out the water intakes difficult.
He said their operational teams and their divers are on standby and waiting for flood waters to recede so they can carry out remedial works, whereby they can clear out the screens and restore water inflow into the Tamavua and Waila Water Treatment plant.
Soderberg said the heavy rain has resulted in severe flooding prompting them to switch off the electricity-operated water pumps for safety reasons.
The public is advised to store water as an alternative.
He said with the Raw Water Pumping Stations offline, this will reduce the raw water inflow into the Tamavua water treatment plant which impacts production levels and will later impact service reservoir levels.
He said between 2 pm to 6 pm yesterday, the Waimanu catchment received a total of 30 millimeters of rainfall over four hours.
He said this particular rain event caused heavy flooding at their raw water intakes at the Waimanu, Waila, and Savura reservoirs.
Soderberg said what they also encountered at their raw water intake and their treatment plants at Waila and Tamavua was an increase in turbidity levels reaching as high as 257ndu and flooding at their Savura Raw Water Pump Station.
He further says on top of the flooding, they also encountered blockage of their intake screens, and it is still currently blocked.
Soderberg says this is severely affecting their ability to produce water at the Tamavua and the Waila water treatment plants.
He says at the Tamavua Water treatment plant, their raw water inflow has reduced from 70 megalitres a day to 41 megalitres a day, whereas at the Waila raw Water treatment plant, the raw water inflow has reduced from 100 megalitres a day to 80 megalitres a day.
Soderberg said these reductions in inflow are affecting their ability to produce enough water to replenish and sustain the levels at their reservoirs, namely the Wainibuku Reservoir, Tovata Reservoir, Kalabu Reservoir, Nasinu Reservoir, Flagstaff Reservoir, Toorak Reservoir, Shipping Reservoir, and the Tamavua Reservoir as well as the Nagatugatu Reservoir, Tacirua Reservoir, Dokanaisuva Reservoir, and the Colo-i-Suva Reservoir.
He said it is because of this, that water supplies to customers will be affected and also if WAF is unable to clear their raw water intake.
Soderberg adds that they apologize for the inconvenience caused; however, water carts will be provided to areas impacted as work will be carried out throughout the day.
