The use of water is of serious concern in our world today, especially because of the way it is being used in unsustainable ways that have led to lots of wastage and deterioration of the environment which is mankind’s earthly home.
It is far easier, and much less costly to reduce water wastage than many people think. In fact, it costs much less money and energy to reduce water wastage than it does to provide new supplies of water—except in situations where governments subsidize water systems in order to reduce water prices and make their acquisition much more easy.
Many studies have been carried out on the usage and sustainability or unsustainability of water. Mohammed El-Ashry of the World Resources Institute once made three profound statements concerning water wastage:
- it is technically and economically possible to reduce water wastage to 15%, and meet most of the world’s water needs in the anticipated future.
- approximately two-thirds of the quantity of water used worldwide is unnecessarily wasted through leaks, evaporation, and other types of losses.
- about half the quantity of water obtained from surface and ground supplies in U.S.A. (the world’s largest user of water) is unnecessarily wasted.
According to most water and environment specialists, the first major cause of water wastage is the fact that water is relatively cheap or easy to acquire
Because water is almost readily available, and governments subsidize it to low prices, users have little or no interest to invest time or money in water-saving schemes.
At times, it seems as if governments efforts to subsidize water is sending out a wrong message that water is abundant and can be used haphazardly or wasted.
On the other hand, if water is not subsidized, low-income farmers might find it hard to buy enough water to meet their agricultural needs.
How water can be conserved (or water wastage reduced) in an environment
In the U.S.A., almost 90% of the quantity of water used in industries is for production of oil, chemicals, paper, coal, metals, and processed foods.
Reduction of water wastage can be achieved by following the example of some industries that recycle their water via recycling and purification in order to reduce water wastage, and most especially costs—water treatment costs.
Another way to reduce water wastage is by depending less on the use of coal-burning and nuclear power plants for the production of electricity.
Coal-burning and nuclear power plants normally use large quantities of water in their cooling systems which have a wide variety of applications in manufacturing and production industries.
Brief summary of some important solutions for water wastage
- collect and reuse household water for agricultural or other purposes (offices, hotels, etc.)
- use water-saving shower-heads and toilets
- recycle water in manufacturing and production industries
- pass laws to enforce regulations for conservation of water in cities
- conduct research and redesign manufacturing and production processes
- plant crops or trees that require little water for their growth, especially in heavily populated cities
- use drip irrigation which has the ability to save water and nutrients by making water drip slowly to the roots of plants, crops, or trees
- fix all leaking taps, or leakages
- use water meters in billing systems.
We can all reduce our water wastage footprint by using water much more sustainably without wasting it. The solution starts with taking adequate steps and acts within our local environments, and stretching our acts globally.
