The forcing of the spring to the surface can be the result of a confined aquifer in which the recharge area of the spring water table rests at a higher elevation than that of the outlet. Spring water forced to the surface by elevated sources are artesian wells. This is possible even if the outlet is in the form of a 300-foot-deep (91 m) cave.
Groundwater recharge or deep drainage or deep percolation is a hydrologic process, where water moves downward from surface water to groundwater. Recharge is the primary method through which water enters an aquifer. This process usually occurs in the vadose zone below plant roots and is often expressed as a flux to the water table surface ...
Artesian well near the Myllylähde spring in Alastaro, Finland. Not all aquifers are artesian (i.e., water table aquifers occur where the groundwater level at the top of the aquifer is at equilibrium with atmospheric pressure). Aquifers recharge when the water table at its recharge zone is at a higher elevation than the head of the well.
A spring supply is a provision of piped mains water to a number of consumers direct from a natural spring.Spring supplies are therefore a source of groundwater, which in most instances has fewer micro-organisms (e.g. coliform bacteria and protozoa such as Giardia and Cryptosporidium) and chemical contaminants than a supply from surface water.
An estimated 55-80% of the city's water supply is derived from the Arkell Spring Grounds, located in the municipal "Southeast Quadrant" well system. [1] [3] [7] [13] Although located outside the city limits, the Arkell Springs Grounds exist on a 350 hectares (860 acres) plot owned by the City of Guelph. The six wells on this property range 14.2 ...
Recently completed infiltration basin for stormwater collection. An infiltration basin (or recharge basin) is a form of engineered sump [1] or percolation pond [2] that is used to manage stormwater runoff, prevent flooding and downstream erosion, and improve water quality in an adjacent river, stream, lake or bay.

Water located beneath the ground surface An illustration showing groundwater in aquifers (in blue) (1, 5 and 6) below the water table (4), and three different wells (7, 8 and 9) dug to reach it. Groundwater is the water present beneath Earth's surface in rock and soil pore spaces and in ...
Storing water underground during years of increased rainfall relieves pressure from the surface water sources and lessens the need for imported water during dry years. Another advantage of groundwater recharge is that it is one of the cheapest sources of water available when compared to desalination, recycled water, imported water, or reservoir ...
