This manual is intended to serve as a basic introductory text book and to provide instruction and guidance to field personnel engaged in the construction, operation and maintenance of small diameter, relatively shallow wells used primarily for individual and small community water supplies. It is aimed particularly at those persons who have had little or no experience in the subject. An attempt has been made to treat the subject matter as simply as possible in order that this manual may be of benefit not only to the engineer or other technically trained individual but also the individual homeowner, farmer, or non-technically trained community development officer.
