Summary
In a time of change of paradigm, in the exploration of natural resources, it is on those which have much easier access that have been suffering significant changes. The exploitation of water resources from an underground source is an example of this and is already the main source of water supply for different purposes in many countries. According to the Interim National Water Plan Version (PNA; MAOT; 2001), in Portugal for public supply are consumed 349 hm3/a of groundwater source, which represents 62% of total consumption, the industry consumes about 179 hm3/a (46% of total) and to irrigation consumption were estimated for 4210 hm3/a, for a total of 64%. The increased consumption of water from underground sources can be explained by the lower susceptibility of these are affected by pollution and extreme hydrological phenomena (prolonged droughts), as seen in the degradation of quality and sharp seasonal variations in water reserves found on the surface. It is therefore important to invest in recovery and adoption of good construction practices of water wells, with a view to sustainable exploitation of the resource. This paper describes the stages of the licensing process, presented the key steps in drilling operations and construction of water wells. Finally, in addition, we present a case study of the construction of an water well for the public supply of two locations in the municipality of Moita. This well was drilled using the rotary with reverse circulation technique, reaching 251 meters deep and captures water from aquifer levels of the base of the Pliocene on the aquifer of the left bank of the Tagus-Sado Basin.
