Reseña

The main goal of this study is to understand the renewal investment needs concerning the urban water cycle in Spain. To achieve it, an inventory of the assets (networks and special infrastructures) that make up the integrated urban water cycle, in its current actual confi guration, was developed. Also, the as-new replacement value of the cost resulting from setting up all that capital was calculated and, then, the anual cost of renewal investment to sustainably maintain the capital was estimated, stemming from different scenarios based on their renewal period. Therefore, the results of this paper are intended to raise awareness on overall renewal investment needs of the urban water sector, in order to ensure the continuity and safety of present and future water services, as well as to promote and maintain those infrastructures that guarantee the provision of water supply and sanitation services.
