Urban Water Security Index

Level Municipal2021

Definition​

The Urban Water Security Index (ISH-U) measures a city's ability to guarantee water in adequate quantity and quality. It ranges from 1 to 5 (or from Poor to Excellent) and assesses the efficiency of water production (vulnerability of water sources) and the efficiency of distribution (network coverage and loss control).

Interpretation​

Despite being an index that considers purely technical and hydrological aspects, and is not capable of capturing perceptions from lived experiences, it is the indicator used by the National Water Agency at the national level.
