At least 500 households in Samoa have been affected by water shortages because of low levels at the Malolo-lelei reservoir.
The Water Authority's, Saharah Sesega Anae, says water is rationed in the morning for some parts of Vaoala and Tiapapata villages and the afternoon for those living in Papauta and around Vailima.
She says engineers have so far located two other sources of water for the reservoir.
The Authority says the low rainfall on the highlands has been the major cause of the problem.
Four water trucks have been supplying fresh water to the affected households.
The Authority says the rationing is not affecting areas where athletes for the South Pacific Games are camping as well as the sporting venues and the catering centres.
