Dry Sanitation Technologies: Developing a Simplified Multi-Criteria Decision Analysis Tool

Safely managed sanitation is indispensable for societies to ensure public health, environmental protection, and economic social development. This could be achieved, in large areas of the world, through dry systems. Dry systems are especially used water-scarce regions low-income households. In dense peri-urban areas, achievement safe necessitates a comprehensive fecal sludge management (FSM) service chain, surpassing mere provision latrines. research introduces an automatic Multi-Criteria Decision Analysis (MCDA) approach, which focuses on particular interface/storage stage FSM chain. The tool aims support decision-making process may useful early stages planning as it compares different technologies with potential application countries. It includes criteria parameters Social, Economic, Technical, Environmental dimensions options (SETEds), being adaptable contexts priorities. main key strengths were found its minimal data requirements ability customize operation maintenance cost parameters. These features particularly relevant data-scarce contexts, where traditional models lead unreliable recommendations or lack solution ownership by users. was applied Ambriz case study, coastal town Northern Angola, West Africa. obtained results analyzed show tool’s provides technology aligned site community characteristics.
