OSAKA -- Debate on private vs. public water management lived up to its billing as one of most divisive issues at the World Water Forum as a two- day plenary session opened here Tuesday.

Lined up against private-sector involvement are developing countries, which believe water would become less accessible and more expensive for low-income communities.

Proponents, however, say privatizing water services would lead to more efficiency and is the best way to solve water-related problems.
