  2. 2. OUTLINE  What are Intelligent/Smart Water Systems/Networks?  Why do we need them?  iWIDGET  project  case studies  To meter or not to meter?  Conclusions © The Smart Water Networks Forum
  3. 3. WHAT ARE SMART WATER NETWORKS?  Smart Water Network solutions improve the efficiency, longevity, and reliability of the underlying physical water network by better measuring, collecting, analyzing, and acting upon a wide range of network events. This can take shape in different phases of the utility process, such as real-time monitoring and automation, operational readiness, or network planning. Source: The Smart Water Networks Forum
  4. 4. WHAT ARE SMART WATER NETWORKS?  A smart water network is an integrated set of products, solutions and systems that enable utilities to remotely and continuously monitor and diagnose problems, prioritize and manage maintenance issues and use data to optimize all aspects of the water distribution network.
