Abstract This study presents the behavior of residual chlorine using computer modeling for a small water supply system located in La Sirena, Cali, Colombia. The study included field work to calibrate and validate the model together with lab determinations. Results show that the kinetics of first and second order together with the kinetics of mixed order can adequately describe the behavior of residual chlorine in this type of network. The research showed the variables that influence the behavior of residual chlorine in the network are: the quality of the input water, chlorine dosing, the effect of storage that increases the water age, and the presence of dead zones in the tanks. The study revealed that 95% of the reaction occurs in the storage tanks due to the small variation in the water level and the negligible reactions at the pipe walls. This study proved that the residual chlorine modeling in this small network in particular is a valuable tool for monitoring the water quality in the distribution network, which is useful to comply with water quality guidelines.

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.

The City

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.
