Nowadays, fresh water is already one of the most critical issues for modern cities. However, we still manage and use the water in the traditional way which is unwisely and wasteful. Therefore, in this article the concepts of modern urban water systems are explored and demonstrated. First of all, water supply, wastewater disposal and rainwater discharge; three systems are planned and designed as one integrated urban water system (IUWS). Then, urban water end users are re-categorized followed by the depiction of special end users, such as landscape and waterscape, and so on. Possible system options are also discussed, like source separation collection, water reuse and multi-stage water utilization, etc. Afterwards, how to properly complete the water cycle within urban area is investigated, whereby new concepts are generated and demonstrated. Based on this concept, the interactions between city capacity and water capacity are discussed from the viewpoint of the city master planning in the end.
