Terminology


Pump Test	The procedure involving pumping water for a specified period of time to determine the yield characteristics of an aquifer.
Static Water Level	The stabilized level or elevation of water in a well not being pumped.
Well pumps are sold by pump dealers, some water well constructors, plumbing supply dealers, and various retail outlets. The water well constructor can tell you the well production and drawdown of the yield test. Using this information and the well diameter, you can select a pump to meet your water needs. The delivery system should produce enough water while using as little energy as possible. Selecting a pump with a capacity greater than the well yield can cause problems, such as muddy or sandy water, pump failure, or even well failure. Several types and sizes of pumps are used in domestic wells. Each has certain advantages, depending on the depth to water, the size of the well, and the amount of water needed. Your pump supplier can recommend the best type and size for your needs. Selection of a pump too large for your well has no advantages and may damage your well.
