Prediction methodology for suitable water and wastewater processes

THIS MODEL WAS COMPUTERIZED AND A MANUAL APPROACH WAS ALSO DEVELOPED. THE MODEL BRINGS TOGETHER A NUMBER OF CRITICAL INPUTS RELATING TO THE EFFECTIVE INSTALLATION AND USE OF VARIOUS WATER AND WASTEWATER TREATMENT METHODS, PROCESSES, AND COMBINATIONS OF PROCESSES. THE OUTPUT OF THE MODEL IS A LIST OF THE PLAUSIBLE ALTERNATIVES FOR WATER AND/OR WASTEWATER TREATMENT IN DEVELOPING COUNTRY COMMUNITIES. THE OUTPUT ALLOWS PLANNERS OR PROJECT ENGINEERS TO LOOK AT ALL THE PLAUSIBLE PROCESSES AND THEIR RELATED CONSTRUCTION COSTS, PLUS THE OPERATION, MAINTENANCE, AND MANPOWER REQUIREMENTS ASSOCIATED WITH EACH OF THE VARIOUS PROCESSES. THE KEY ELEMENTS OF THE APPROACH ARE: THE SYSTEMATIC EVALUATION OF THE IMPORTANCE AND INTERRELATIONSHIPS OF ALL RELEVANT ASPECTS OF THE PROBLEM, SUCH AS TECHNICAL, ECONOMIC, SOCIAL, POLITICAL, AND CULTURAL FACTORS; THE ASSESSMENT OF ALTERNATIVE COURSES OF ACTION; AND AN ANALYSIS OF IN-COUNTRY COSTS AS THE BASIS ON WHICH POLICIES CAN BE DETERMINED AND DECISIONS MADE. REPORT COVERS THE PREDICTIVE MODEL"S FORMAT, DATA REQUIREMENTS, SELECTION OF APPROPRIATE COSTS, AND COMPUTERIZATION. A TEST MODEL USING AN ACTUAL CASE STUDY IS INCLUDED. SEPARATE MANUALS COVER MANUAL AND COMPUTER COMPUTATION METHODOLOGY AND DATA REQUIREMENTS.
