…Edwards Underground Water District has developed these recommended minimum well construction standards. The method used to construct Edwards’ wells, and the construction details themselves can be a major factor in the quality and quantity of water being produced. The unique nature of the Edwards Aquifer as a limestone formation has made water well construction specialized and different from that in all other areas of the State. This manual is provided as a service to the residents of the District to inform those unfamiliar with the water well profession about generally accepted drilling procedures, practices, and construction specifications for Edwards Aquifer wells. It primarily addresses the construction of domestic wells.

 …The suggested water well design and construction information presented herein is provided for educational purposes in an effort to improve upon individual home water supply systems. There is a wide range of variables affecting the type of construction necessary from one well to the next. Any unusual situation many times will require a decision to be made on the spot which may alter the construction of the well not covered in this manual.

The location of a well will also be a deciding factor in the quality and quantity of water capable of being produced. It is recommended that prior to drilling a well, the individual having the well drilled, obtain all available information on the geology and groundwater resources of the area. Much of this information can be obtained from nearby well owners, water well drillers or public agencies.

The Edwards Underground Water District (now the Edwards Aquifer Authority) maintains records of new and historical well data which is made available to the general public.
