System-based decision trees for the selection of sanitation technologies

Decision trees, also called algorithms, provide a systematic and transparent representation of the decision process. Existing algorithms applied to the sanitation sector are either too simple, failing to consider the entire sanitation chain, or excessively complex, leading to counterproductive results. This work presents simplified decision trees to support the selection of sanitation technologies compatible with the local context while, at the same time, it helps to guarantee the required technical compatibility along the sanitation supply-chain, i.e., from the interface to the final destination of products.
