Spaniards who use "excessive' amounts of water may have to pay more for it in future, the government said, seeking ways to curb water use after two years of drought. After the worst drought on record in 2005 and below average rainfall again in the year ended on September 30, the country's reservoir levels dropped to their lowest in a decade. Environment minister Cristina Narbona said she was planning to guarantee a minimum amount of clean water for everyone and would raise prices above that limit. "In principle, in line with a proposal made by Ecologists in Action, we suggest a minimum of 60 litres a day per person,' she said. "(There will be) a reform of the water law to penalize excessive consumption via tariffs charged,' Narbona said at the start of a national water council meeting, which is due to debate several proposals.
