"Natural treatment plants are needed for development, which is commonly applied in Germany," he said in a seminar on 10 million new clean water lines in 2013 here Wednesday.
He said the natural treatment plants is a concept of taking water from underground sources.
The concept is commonly applied in Germany where 65 percent of basic water sources is the ground, 9 percent springs, 5 percent wells and 21 percent of the ground surface like lakes and rivers.
"Most of Germans don`t have water purifier installations because drinking water is obtained from springs and the ground on mountain slopes," he said.
