Answers
Explanation:
(17.)Ans) Water is one of the basic human necessities but a large proportion of the Nepalese population is devoid of access to safe and adequate drinking water. According to the Department of Water Supply and Sewerage in Nepal, even though an estimated 80% of the total population has access to drinking water, it is not safe.Oct
(18.)Ans.) The lack of infrastructures and the high level of pollution due to agricultural pesticides, fertilizers and waste water are the main causes of the problems of lack of water. ... The Nepalese capital produces around 150 tons of waste daily that are uncontrollably discharged into the rivers.
( 19.)And.) Nepal is one of the most water rich nations on the planet; however providing safe drinking water to communities is an ongoing issue. Rainwater harvesting has been used to help solve this problem but current systems can have water quality issues.
(20.)Ans.)Water purification is the process of removing undesirable chemicals, biological contaminants, suspended solids, and gases from water. The goal is to produce water fit for specific purposes. Most water is purified and disinfected for human consumption (drinking water), but water purification may also be carried out for a variety of other purposes, including medical, pharmacological, chemical, and industrial applications.
