Asset management can help the water sector with this. The water sector manages facilities with an estimated replacement value of 100 billion euros. It is important to make optimal use, maintain and replace these ‘assets’. Assets are all the physical (business) resources and facilities that a company or organization needs to perform the work properly. Assets in the water chain are, for example: pumps, sewage pumping stations, treatment plants, waterways, dikes, buffers and discharge pipes. Asset management focuses on minimizing costs over the entire lifetime of these facilities, without undesirable risks. This covers the entire process of investing and financing, maintaining, renovating and replacing. Water boards, water boards, drinking water companies and municipal sewerage companies can use asset management to control costs in the water sector, without losing sight of quality.
