What is it about?
Prioritizing the replacement of a pipe is a challenge for utility managers. This work proposes a methodology to prioritize pipe replacement according to water and energy savings per monetary unit invested – economic prioritization.

Why is it important?
Efficient management of water distribution networks involves factoring in water and energy losses as the key criteria for planning pipe renewal. The results demonstrate that using the unit headloss criterion (ageing) neither water, energy nor the investment is optimized. Significant water and energy savings are not fully exploited.
Perspectives
This work is an approach that may lead to high water and energy savings when operating water distribution networks. This work involves to have solved the hydraulic problem (a model is required) and also to have considered leakage at nodal level.
