Smart Water City

short description:

The success of "Smart Cities" is based on the use of various information and communication technologies (ICT) in interaction with the society. As a result, cities can be made more efficient and sustainable across systems, and municipal benefits can be generated. In addition to the reliable supply of fresh water to the entire community, the urban water infrastructure also guarantees the environmentally tolerable disposal of accumulated wastewater and the safe discharge of rainwater runoff. Although real-time controlling can be found in approaches, water supply and urban drainage systems are considered separately. Additionally, a separation of control options of the whole system exists also between end consumers and infrastructure operators.

The goal of this cooperative F&E – project is not only to examine a “Smart Water City”, but also the effects of a cross-linked water infrastructure on urban population and vice versa. For this purpose, a smart urban water infrastructure is implemented into an extended urban structure including the development of innovative communication technologies for the interaction between population, designers and decision makers. On this basis, intelligent public and private services for an efficient use of resources can be realised to investigate the potentials and effects of the interactions between urban population and technical water infrastructure. Together with the life cycle costs, the municipal added value of the smart urban water infrastructure can be determined.

The project consortium is using a two-stage approach for the implementation and testing of a “Smart Water City”. In the first step, the existing show- and experimental room “Smart Campus” at the Campus Technik of the University of Innsbruck is extended to determine the impacts of integrative and cross-system applications. The “Smart Campus“ functions as idealised experimental and demonstration object to show and to experience actors of the urban water cycle the functions, potentials and applications of a Smart Water City. In the second step, an intelligent water supply system is tested and examined in a less idealized, real urban tested. By using the Eco Plus Park Wiener Neudorf, the potential of an intelligent water supply system is determined under real conditions.

 

The realization of a smart monitoring and controlling network will increase quality in supply reliability (detection of pipe bursts and leakages as well as contamination) and failure probability (controlling drainage operation in sewer systems). Because of the holistic approach, new intelligent approaches for the operation as well as new operation and maintenance models as multi-actor partnership can be realized. For example, "smart rain barrels" are real-time controllable storage volumes for innovative rainwater management that are installed and operated at the household level. As a result, a decentralized retention of rainwater for irrigation purposes can be used (saving drinking water) and at the same time the discharge volumes into the sewage system can be reduced or shifted to periods with sufficient capacities. Through the interaction of a large number of smart rain barrels in a settlement area, it is also possible, for example, to reduce emissions into waters, but also to reduce the risk of flooding.
