What do the governments and people expect from water supply in developing countries?
Do they expect safe water supply to prevent epidemics; washing and bathing water supply to lighten the burden of getting water; or industrial water supply to promote industries?
The Millennium Development Goals Report 2013 indicates that over the last 21 years, more than 2.1 billion people gained access to improved drinking water sources. The proportion of the global population using such sources reached 89 per cent in 2010, up from 76 per cent in 1990. This means that the MDG drinking water target was met five years ahead of the target date, despite significant population growth. However, 768 million people still drew water from an unimproved source in 2011 and even the people who gained access to improved drinking water sources cannot be said to have led comfortable healthy lives.
It is absolutely necessary for safe water supply to maintain enough water pressure to prevent the entry of polluted water from outside and residual chlorine to disinfect pipes. However, that has not been practiced well in developing countries. We have seen so many water works that were constructed by the aids of developed countries but have not worked well because of the poor operation and maintenance.
We will propose the operation and maintenance catered to counterparts’ expertise and the improvement to more readily operable facilities.
