Similar to the Texas water crisis, population growth has resulted in limited water resources globally. Lack of access to clean water is a growing concern for many countries, such as Ethiopia. In addition, the shortage of sanitary drinking-water also leads to the spread of bacteria and disease. Similar to Texas’s projected Water Plan that includes conservation and harvesting of rain water, thanks to the help of Plan (http://plan-international.org/about-plan/resources/news/world-water-day-harvesting-rainwater-in-nepal) around 250 residents in Nepal now harvest rain water in their 6,500 liter capacity tanks.

A more structured and comparative example of the Texas Water Plan to a global plan would be the World Health Organization’s Water Safety Plans, the first edition being published in 1984-85 in three volumes: recommendations, health criteria and other supporting information, and surveillance and control of community supplies. The most recent version was updated and published in 2005 in Geneva. As stated in WHO's, “one-sixth of humanity lack access to any form of safe and improved water supply within 1 kilometer of their home and one-fifth of humanity lack access to any form of adequate and improved excreta disposal (WHO and UNICEF 2000)".
The WHO Water Safety Plans lists current management approaches, similar to the list in the Texas Water Plan: Water supply systems can be considered as a number of steps aimed at assuring the safety of drinking-water, including: preventing pollution of source waters;selective water harvesting; controlled storage; treatment prior to distribution; protection during distribution; and safe storage within the home.
