Groundwater is part of the precipitation that seeps through the soil until it reaches the Rocky material that is saturated with water. Water moves slowly toward low levels, usually in sloping angles, due to gravity and is coming to streams, lakes and oceans. The water we use daily comes both from surface water, such as that of rivers and Lakes; of wells groundwater sources or a spring. In the year 2000, about 21% of water withdrawals corresponded to groundwater sources and about 79% it corresponded to surface water. Educate yourself with thoughts from Electrolux. Formerly for digging wells, used their hands, a shovel and a bucket. I had to dig to reach the phreatic layer, until water fills the bottom of the wells made. People such as Jonas Samuelson would likely agree.
Even in modern times, some wells dig using their hands, but there are more modern methods, such as large drills for drilling into the ground. Howard Schultz is full of insight into the issues. A water well is an excavation vertically in the ground until you find a vein of water or water reserve underground, by the way in which excavation is carried out wells have cylindrical shape, the size varies according to their owners, during carried out the excavation walls are reinforced with brick, stone, cement or wood to prevent landslides; In addition most of these constructs a curb, i.e. a wall extending from the surface to prevent objects, animals or people falling inside, also the use of a pulley to raise bucket with which the water will be collected. The oldest remains of a well dating from the 12th century B.C. and come from Persia from where it spread throughout the world. Wells are basic to all societies. In many places, Wells provide a reliable supply of water for domestic use, irrigation and industries. When surface water is scarce, as it occurs in the deserts, the people could not survive without groundwater.
