The document discusses the need for proper maintenance of water service assets to ensure their continued serviceability for future generations. It notes that from the 1950s-1970s there was population growth and economic boom which required building new water infrastructure, raising public debt. From the 1970s-1990s, environmental awareness increased standards. The document estimates renewal needs at 15 billion euros but notes current planned investments are not enough. It argues that more funding is needed for maintenance and better asset management to avoid leaving problems for next generations to solve.
