SINGAPORE (Apr 9): Water is the most important resource in the world. Although nearly 70% of the world is covered by water, only 2.5% of it is fresh and 0.007% is used to feed the global populace. The global population is about seven billion and not everyone has access to water.
According to the United Nations World Water Development Report 2018, global water use increased by a factor of six over the past 100 years, and is increasing by about 1% a year.
Water poverty remains widespread globally, in developing to developed countries. Only last summer, California experienced a drought. In the US, an estimated US$540 billion ($709.4 billion) gap exists between current spending and the projected needs for water and wastewater infrastructure over the next 20 years. Most of the nation’s water pipes are aged 50 and above, and are allegedly the main cause of lead contamination such as in the Flint water crisis.
