Resumo(s)
It is critical to ensure the efficient management of water supply networks to reduce water
losses caused by cracks and ruptures in the underground infrastructure. These issues have an
impact on environmental sustainability, resource efficiency, and operational costs. This issue
is especially important in aging infrastructure, where unbilled water losses frequently exceed
acceptable limits.
The study's main goal is to identify critical areas within Albufeira's water supply network, which
experiences 23% annual unbilled water losses. The study uses a multi-criteria analysis
methodology based on the Analytical Hierarchy Process and Geographic Information Systems.
The study looked at environmental, physical, and operational factors to create predictive maps.
The data were transformed into a hierarchical model, with weights assigned based on expert
contributions reported in scientific articles. The model was validated using techniques such as
acoustic geophones and thermal drones.
The findings show that the proposed methodology significantly improves the efficient
management of water resources by reducing losses and costs while promoting sustainability.
High-risk areas were identified, allowing for prioritization of maintenance interventions.
Applying the Analytical Hierarchy Process model reduced failures from 35% to 40%, detecting
leaks efficiently. It is concluded that integrating and Geographic Information Systems,
Multicriterial Decision Analysis, and Analytical Hierarchy Process improves water supply
network management by reducing water losses, operational costs, and environmental
impacts.
