The Samoan prime minister, Tuilaepa Sailele, says a new 25 million US dollar water improvement project will lead to a marked increase in the quality and consistency of the water supply for thousands of Samoans.
The scheme will benefit a third of the population - those resident northwest of Upolu island and the eastern side of Savai'i.
The prime minister has told people at the launch of the scheme that it will also enhance economic activity and public health.
And he says the supply will be metered to cut wastage.
The Water Authority is keen to cut average daily consumption from 340 litres per person to 290 litres by 2005.
