The overall goal of this study is to understand the renewal of investment needs concerning the urban water cycle in Spain. To achieve this objective, three specific goals were identified:
1. Performing an inventory of special infrastructures and networks that make up the integrated urban water cycle, in its current actual configuration.
2. Calculating the as-new replacement value of the cost resulting from setting up all that capital.
3. Estimating the annual cost of renewal investment to sustainably maintain the capital, stemming from different scenarios based on their renewal period.
The scope of this project covers the analysis of urban water cycle investment needs, distinguishing between water supply and sanitation services. In turn, each part of the integrated water cycle is broken down into networks and special infrastructures.
