(t) “Water supply system” means the source, works and auxiliaries for collection, treatment and distribution of potable water from the source of supply to the water service connection.
(u) “Well” means an artificial excavation that derives water from the interstices of the rocks or soil which it penetrates. Wells referred to in Sections 1040.12 and 1040.13 are “shallow” or “deep” depending upon whether they derive water from “free” or “confined” ground water respectively. However, wells of depths greater than fifty feet in unconsolidated formations shall be classified as deep wells. Any exploration, testing or production well for whatever purpose constructed, is considered a water well, and subject to this chapter, since improper construction can lead to ground water contamination.
(1) “Bored well” means a well that is excavated by means of a soil auger (hand or power) as distinguished from one which is dug or drilled.
(2) “Drilled well” means a well that is excavated wholly or in part by means of a drill (percussion or rotary) operated by cutting or abrasion or by use of a water jet.
