The TAWARA_RTM project aims at developing a complete platform to control the quality of the tap water with respect to the radioactivity content. The platform will provide a real time measurement of the activity in the water (measuring the gross alpha and beta activity) to verify whether the distributed water is far from the limits set by the EU legislation (see Directive 98/83/CE of the European Council) reaching thresholds that require rapid actions. In case of an alarm due to an activity in the water lager than the defined thresholds, a warning message is sent to the water plant management to verify the need of stopping the water distribution. At the same time, a second part of the system is activated, to determine the nature of the contamination by gamma ray spectroscopy, defining the nature of the contamination and the corresponding counter-measures. Moreover, the determination of the contaminants is needed to establish the effects on the population and produce a full information report to the Civil Security Authorities. The prototypes of a real time monitoring system and spectroscopy analyzer will be designed, built, tested under laboratory condition and finally installed at the water plant in the North Waterworks Plant [Zakład Wodociągu Północnego] of Warsaw managed by the Warsaw Waterwork Company (Miejskie Przedsiębiorstwo Wodociągów i Kanalizacji w m.st. Warszawie S.A. – MPWIK), for the demonstration campaign. The site selected for the demonstration is particularly problematic for possible radioactivity contamination being communicating through the network of rivers and canals with the Chernobyl region and being close to a Polish National Nuclear Waste storage site.The TAWARA_RTM project will include the development of the complete platform including the fast Real-Time Monitor system (RTM), the Spectroscopic system (SPEC) as well as the Information and Communication System that will be designed to include in future also chemical and biological sensors.
