The importance of water management
Water management affects many aspects of our lives. Water is so common that we often do not think about where it comes from or where it is managed. But, bad water management can really hit us hard. Below are some key ways in which water management is important.
1. Drinking water: humans need to drink around 8 glasses of water a day in order to get sufficient hydration. So clean drinking water is a necessity for us. Without water, we can only survive for a few days at most. But, if we have water and no food, we can survive for several weeks. This shows just how crucial it is that we have daily access to clean water that is suitable for drinking. If we have pets, they will need daily access to water too.
2. Washing and cleaning: we also use water to keep ourselves, our clothes and our homes clean and hygienic. A clean water supply is important for this too. From washing our hands before a meal to deep cleaning a hospital floor, we need clean water for almost all aspects of good hygiene.
3. Agriculture: water is used throughout the world to grow crops such as grains and fruits. A good water supply is needed to prevent hunger and famine.
4. Leisure and fun: swimming, boating and many other leisure activities involve water. Swimming pools and other facilities need to be well maintained so that they remain safe and enjoyable places to be. Swimming pool water needs to be managed by treating it with chlorine and regularly testing its levels of bacteria and other substances, for instance, to ensure that it is safe for people to swim in.
5. Biodiversity: managing water well ensures that we do not deplete or contaminate rivers, lakes and other important water sources which are habitats for a wide range of birds, mammals, fish, reptiles and amphibians as well as water dwelling plants.
