1能源和水的自由和不受限制的可得性和可得性能够促进经济的增长并支持生活质量。水-能关系被认为是全球增长的水市场在未来几年必须面对的最重要的多学科挑战之一。目前，许多水系统没有从长期可持续性的角度进行管理。水务公司(WU)面临着进一步的挑战，如基础设施的老化和低成本回收，导致运营和维护(O&M)缺乏资金。在水的生产和分配的所有阶段，从提取、处理到运输，都需要能量。能源成本是WU最关心的问题，无论地理位置、规模和供水网络效率水平如何。另一方面，在发展中国家，吴邦国很难改善他们的服务或将他们的网络扩展到没有服务的社区。考虑到所有这些事实，并考虑到迫使对来自不同领域(市场、技术、社会……)的压力作出反应的经济和竞争情景，因此需要实施新的方法和流程，以满足这些日益增长的需求，并设法实时管理反应和行动。智能软件解决方案可以应用于网络，无论它们是否有智能测量和大量的数据或较少的记录数据。它们增强了操作员的能力; knowledge of this data, turn it into useful information for decision-making related to the operation, maintenance and the design of the water supply network. In this paper, an application of an intelligent software solution is presented. WatEner, a smart Information and Communication Technology (ICT) solution that combines the key factors of energy consumption with further operational requirements of drinking water supply to improve the management of water supply networks, has been tested with good results by the WU of the city of Karlsruhe, a water rich area in North-West - Europe where the main objective was to save energy in the drinking water distribution. As a conclusion, a non-structural solution for the water-energy nexus can have a great impact on several matters (e.g. climate change, carbon footprint, WUs balance sheets, water losses) with reasonable investment in only a few sensors in the water supply network.
