1.0 Introduction
Everything which lives needs water to survive. There are a lot of places in the world where we can find such problem as lack of clean water, and most of these places are developing countries. These include areas in the north of China, India, and the western United States. Global climate change only exacerbates the problem of water shortage. The World population is currently 7 billion people, and each of them needs at least a liter of water a day. What is more, with the explosive growth of the world population, water

This process called reverse osmosis. This process is used in North African countries. For example, in Tunisia water sources comes from desalination, with Tunisia spending over 70 million euros in desalination projects in 2010 (The International Desalination and Water Reuse Quarterly industry, 2010). Cost of a 10-15 million gallons per day plant would be between $190 million and $260 million.

3.2 Groundwater Exploitation

The other technique, which could help to provide water to arid areas in North Africa, is the exploration of groundwater. Ground water comes from the rain and when hitting the ground water moves to the ground between soil through cracks in rocks, which calls aquifers. Using underground water is suitable for areas, which are not close to any water source or, which are in the desert. The cost of accessing to the underground water is very expensive; it costs nearly $550,000 for one pump (New Jersey Ground water association, n.d). Using this technique can’t be done everywhere, because in some places in the world the underground water polluted and leaking gas pipes. This kind of technique used in Egypt. Groundwater development in Egypt is not only confident in the Nile Valley and the Delta, but also applies to desert regions, where a large number of non-renewable underground water stored

3.3 Rainwater Harvesting
The other technique, which can help the water crisis is harvesting of
