One of twelve water treatment technology units, this student manual on general plant operations provides instructional materials for seven competencies. (The twelve units are designed for a continuing education training course for public water supply operators.) The competencies focus on the following areas: water supply regulations, water plant parts diagram, water sources, monthly operation reports, daily demand variation, average water reserve, and water shutoff guide. For each competency, student objectives, resources (e.g., information sheets, forms, appendix materials, and references to manuals, pamphlets, or books), learning activities, and evaluation activities are provided. The appendices contain information sheets on storage, sources of water, records and reports, and record-keeping, calculations and simple hydraulics. Generally, an evaluation form with answer key is provided for each competency. (JH)
