Stable and reliable operation of the drinking water distribution system is very important for vital human needs. Moreover, its integration with the use of Wireless Sensor Networks gives a valid way for better monitoring of water quality. However, this doesn't provide a higher resilience of the system in a case of many possible disruptions, caused by natural, inattentive or malicious factors. More or less, the vulnerability of this system performance highly depends not only on the power supply but on the data transmission quality factors, which affect a sensitive data in all stages of its delivery. Due to this, the authors proposed a novel idea by developing a digital model for monitoring of quality-focused parameters in a data delivery over Wireless Sensor Network based drinking water distribution system in Latvia. We proposed a concept of Quality of Resilience for overall system of Wireless Sensor Network for control of water distribution system. We also proposed and implemented a digital model, investigations, insights for self-organization in Wireless Sensor Networkbased water distribution system, which would help to increase the system's resilience to various short-time disruptions. This model implements a quality control in data delivery and provides the opportunity to re-organize topology of the sensors, aiming to maintain a stable operation of a system and reduce a percentage of messages from data processing system (broker) for data retransmission in a failure of any gateway - controller. This integrated solution for self-organization of sensors and data delivery with a selected Quality of Service level would increase both - the overall system's resilience in a case of shortterm disruptions and the stable system performance at that time.
