I found this article in Internet, I made some modification 

water issue in Palestine 

Palestinian people suffer from the water problem and the first responsible is the Israel occupation that control the water and deprived millions of Palestinians of the population of enjoyment or even to act minimum of their natural right where and which is supposed to guaranteed by laws and international conventions and human rights organizations and peace treaties.

The water crisis in Palestine contrived, and it is political par excellence, Palestine from countries that have a good renewable water sources in the region Where meteorological data indicate that in the past one hundred and fifty years the country did not witness a trapped the rain, the rainfall over Jerusalem the rate 564 mm per year, In addition, the West Bank, has an exceptionally high rate of feed water and  low groundwater runoff rate This means it has a good stock of groundwater, but that "Israel" deny access to it.

Oslo agreement has pointed to Israel's recognition of Palestinian water rights. However, the definition of these rights was postponed to the final status negotiations. Add to that the agreement is devoid of explicit text emphasizes the control of the Palestinians on the water, including the areas classified as "A", That is to drill a well must get Israeli approval, and often the answer is no, because the joint water board requires unanimity in its decisions.

Recommendations of the World Health Organization, the individual needs to be about a hundred liters of drinking water per day, to be available and affordable. While the Palestinian citizen not only gets a percentage ranging from 30 ~ 60 liters per day, according to the region and the chapter, and in some areas gets 100 liters, while the settler gets times this figure.

In the West Bank, the Israeli Water Company (Mekorot) to withdraw large amounts of groundwater inventory, or from wells located directly on the armistice line (free of charge), and then sell these waters again to the West Bank municipalities. And often gets severe deficit and a shortage of water among the Palestinians, especially in the summer, what drives people to buy water at high prices. The reason for this is that the Israeli companies cut off the water from the Palestinians and give it to the Israelis, because Israel is a tool to use water pressure and blackmail and collective punishment.

The construction of the apartheid wall has led to book a lot of water wells, and to deprive the Palestinians of an important source of groundwater, Palestinian areas and the loss of future production on land that swallowed along the wall.

In the negotiations Israel presented figures are incorrect in terms of the ability of groundwater basins and the maximum allowed in each basin, where it was to manipulate the numbers especially the eastern and western basin What serves the Israeli interest to label basins closed basins, and do not allow any Palestinian to dig wells there.
