Abstract The publication presents the main types of incidental events in collective water supply system. The special attention was addressed to the incidental events associated with a decrease in water quality, posing a threat to the health and life of inhabitants. The security method against incidental contamination in the water source was described.

This paper provides a detailed look into the historical development of the water supply system of a big industrial city and its impact on the river environment and needs of the wastewater treatment system. The city of Brno, Czech Republic, was chosen for this study because it has a long history in the field of water supply, and the city has changed rapidly over the last 200 years. The city’s development necessitated an adaptation of drinking water sources, most significantly the use of the Březová nad Svitavou facility, which resulted in a change of condition of the Svitava River. The notable decrease in river flow, aided by industrial development of settlements within the Svitava River catchment between 1850 and 1950, strongly contributed to the spread of river pollution. However, the construction of wastewater treatment plants during recent decades led to a restoration of river quality and, consequently, of the entire environment of the Svitava River catchment. This paper also presents a view on activities connected with the long term surface water quality monitoring and improvement with regard to water quality conditions in spring areas and the river network influenced by the water supply system.

The study was carried out to assess the performance and management analysis of Pasthali Water Supply System. Various data collection tools such as questionnaire survey, field observation and key informant interviews were used along with water quality analysis at the source, treatment plants, point of delivery and use. The filter bed media analysis was also carried out to assess the uniformity in the bed media. Mcrobial contamination in treated water was found due to improper sand granular used in filtration unit that hinder efficient removal of the microbes, lack of chlorination in the unit caused increase in microbial contamination at the point of delivery along with the unhygienic environment at the distribution tanks. Manual chlorine addition for three days was found to be effective in reducing microbial contamination drastically, but the water is recontaminated once delivered and stored at the household level. Improper handling and unhygienic storage location were found to be the major causes of increased contamination at households. The status of the water source is not safe either and seeks intermediate attention. The operation and management of Pasthali Water Supply System solely depends on water tariff and bears financial loss annually. The study also concludes that there is surplus of treated water termed as non-revenue water in the system. Proper granulation of the sand in the filtration unit and chlorination are must to ensure the safe water along with the awareness on the water management at the household levels. Supplying of non-revenue water to the nearby villages could be a potential to generate resources that ultimately strengthen financial aspects of the system and build resilience to financially break-down in the future.
