Bored Well Mean?
A bored well is a well that's bored rather than drilled. It's smaller in diameter than a drilled well. It's designed to take advantage of low-yield, shallow aquifers and remain bacteriologically safe through the use of a combination of casings, collars, concrete slabs, sand, location and detailed specifications.
Depths of bored wells range from 30 to 80-feet and the specifications regarding the depth of the collar or casing, concrete slabs or covers, and proximity to potential sources of pollution may vary according to locale.
Trenchlesspedia Explains Bored Well
Bored wells are not the stars of the trenchless show (nor is that the reason they're bored), but they can keep practitioners of the arts of trenchless technology working during slack times.
The specs for bored wells vary from state-to-state and are often written by or developed in conjunction with state health departments, so as to ensure uniformity among the designers, engineers, boring contractors, and health officials at the county and state levels.
