Now, the two springs and the Big Well supplied the city for a number of years until 1942 when the second Influx of workmen commenced. These were needed In order to build the large Baelo Magnesium plant which produces a light strong metal from which airplane parts and In­cendiary bombs are made| some 14,000 men were employed on this project, which cost In the neighborhood of $64,000,000. In order to supply all these men with water It was necessary to build a battery of 10 wells from which over 13,000,000 gallons of water can be produced each day. An ^Artesian" well means one from whioh the water flows naturally, without assistance from mankind. This is made possible by the water entering an impervious strata from a point high in the mountains, and being con­fined in this channel until it ie "tapped* by a well. The water then rises until it attains an outlet and thus we have an artesian flow. However, as more and more wells are drilled, this has a tendency to decrease the flow, and in such instances a pump is installed in the well to assist the water in rising to the top. The temperature here in the desert sometimes reaches 120 degrees in July and August, and of course a great deal more water is required than in moist, cool climates. The per capita consumption here in those months has reached 640 gallons daily, which is about four times the national average.
