Proper installation, inspection, operation, maintenance, repair and management of small water systems have a significant impact on the operation and maintenance cost and effectiveness of the systems. The objective of this manual is to provide small water system operators with the knowledge and skills required to operate and maintain these systems effectively. This manual contains information on: (1) what small water system operators do; (2) sources and uses of water; (3) how to operate and maintain wells and pumps; (4) the operation and maintenance of small water treatment plants; (5) the disinfection of new and repaired facilities as well as water delivered to consumers; (6) techniques for recognizing hazards and developing safe procedures and safety programs; (7) laboratory procedures for analyzing samples of water; and (8) procedures to develop a reasonable rate structure. The document was developed to serve as a home-study or self-paced instructional course. The appendices include a trial final examination (with answers), tips on solving small water system arithmetic problems, water abbreviations, a glossary of water words, and a subject index. (TW)
