There are concerns in American Samoa that the main island's current water resources will struggle to cope with growing demand.
The executive director of the American Samoa Power Authority, Utu Abe Malae, says sometimes the StarKist Samoa cannery's demand for water exceeds the Authority's capacity.
He says Starkist's demand for water has increased but the Authority is faced with old infrastructure that loses at least 50 percent.
Utu Abe Malae says with the Tri Marine cannery opening up next year there are concerns as to whether there will be enough water for both canneries and the rest of the island.
He says the canneries will need to have storage tanks in place because they will not be able to pump water directly from the mains during peak hours, at will.
