Over the past 100 years, water consumption has steadily risen due to increased demand for water both in people’s homes as well as demand for water for agriculture and industry.
Purifying water requires a significant amount of energy and money and so people are being advised to reduce their water consumption where possible. Possible methods of doing this include:
Abstraction is extracting water from natural sources for human use. There are many methods for abstracting water which include:
Some people may be opposed to these methods, especially the creation of reservoirs. These are major projects that flood large areas of land, and so destroy habitats and change the appearance of the area.
Water is abstracted from certain places but the areas where the water is needed may be many miles away. The water must be piped to these areas to provide irrigation for growing crops, water for drinking and water for sanitation.
Distributing water is expensive and many areas of the world do not have access to clean water, especially as some of the driest areas of the world are also the poorest. This water is not only needed for drinking but also to provide irrigation for growing crops to prevent starvation.
