The Water Authority of Fiji (WAF) would like to advise our customers that a burst has developed on the Waimanu Raw Water Rising Main, fed by Pumps 1 and 2, and will be shut down in order to allow our technical team to safely access and excavate the site to assess and determine the extent of the damage.
As these two pumps and main contribute to over 40% of the flow into the Tamavua Water Treatment Plant, we anticipate that production and reservoir levels will be affected significantly.
In preparation for this, customers in the areas listed below are kindly advised to store in their homes, while it is still available, sufficient amounts of water to last them for at least 2 to 3 days and are requested to use water wisely during this time.

The burst on the line is a result of the pumps being tripped off which was triggered during a power switch over from our standby Gensets to the power grid, after a planned power outage was restored and normalised this morning (03/03).
The pipe had burst as the Waimanu Raw Water Pump Station pumps raw water uphill and once triggered off all of a sudden, pumping upstream stops and water gravitates towards the pump station house. Once the pumps are activated again, a pressure surge occurs resulting in a burst in the weakest point.
This incident is commonly referred to as a ‘water hammer’.
A water hammer is the result of a pressure surge or high-pressure shockwave that propagates through a piping system when a fluid in motion is forced to change direction or stop abruptly.
Water carting trucks are on standby and can be requested in the case of an emergency by calling 5777 (all mobile networks).
We sincerely apologise for any inconvenience caused and we seek your patience and understanding until such time the water supply normalises.
For further enquiries, customers can call 334 6777 or short code 5777 (all mobile networks), or email firstname.lastname@example.org
