Abstract
In this study, we investigated the modelling and optimization of drinking water supply system reliability in the village of Zaben, Czech Republic. An in depth overview of the water supply network in the municipality, passport processing and accident and malfunction recording is provided based on data provided by the owner and operator of the water mains as well as the data collected by our own field survey. Using the data processed from accident and failure reports in addition to water main documentation, the water supply network in Zaben was evaluated according to the failure modes and effects analysis methods. Subsequently, individual water supply lines were classified based on their structural condition. In addition, a proposed plan for financing the reconstruction of the water supply mains in Zaben was created. As such, this study provides an overall assessment of the water supply network in Zaben alongside a proposed plan for the structural restoration of the water supply system, which accounts for the theoretical service life of the system and the financial resources of the owner.
Highlights
Drinking water supply systems have significant impacts on the quality of human life, health, and hygiene
Water supply networks in the Czech Republic are an extensive grid of 77.146 km of water mains that supply water to 9.93 million people—approximately 94% of the population
We applied the methodology for evaluating the technical condition of the water supply system, according to the general Failure Methods and Effects Analysis (FMEA) approach
Summary
Drinking water supply systems have significant impacts on the quality of human life, health, and hygiene. It is possible to mainly include emergency services in the form of an integrated rescue system, especially the fire safety of the area and health care, as well as food, chemical, industrial or agricultural production This issue is a severe issue in other countries around the world, which corresponds to the subject of many publications interest [3,4,5,6,7,8,9,10]. The of the supply of drinking water means a reduction of human life living standard, author of [11,12] stated, using the example of a pipe route failure, that even a small-scale failure can and a reduction theentire functionality of other parts on which is directly dependent It is cause the collapse ofinthe system and affectstate the performance of society the entire water network. Lines E, F and G have a low operational reliability [20]
