Abstract. The subject of the publication is to present the method of water consumers safety analysis and assessment to implement the so-called Water Safety Plans (WSP), recommended by the World Health Organization (WHO) in Poland. The paper presents the method of water consumers safety analysis and assessment, which is based on failure mode and effects analysis (FMEA). The failure mode and effects analysis is widely used to analyse the reliability and safety of products and processes in technical systems. The procedure in the FMEA is based on the identification of potential undesirable events, assessment of effects and determining the causes of these events, assessment of frequency, the possibility of detection, estimating validity of the actions and estimating how to prevent undesirable events, re-examining and assessment of these events. The developed method of water consumers safety analysis and assessment is a complement and extension of recommended for WSP matrix methods, which according to the author's opinion is not sufficient for a proper analysis of undesirable events that may happen in collective water supply system (CWSS). The use of the FMEA method will allow for better identification of existing hazards and to determine the cause-effect relationships between them. Reliable access to drinking water is one of the basic conditions for the development of civilization.

“…The investigations related to the technical condition of buried infrastructure are extended and many mathematical modeling methods and special software are used to increase the efficiency of the management of water-pipe networks [6][7][8]. The prediction of failure rate could be carried out not only using typical statistical methods [9], but also using algorithms based on artificial intelligence [10][11][12].…”

The paper describes the results of failure rate modeling using K-nearest neighbours method (KNN). This algorithm is one among other regression methods, called machine learning methods. The aim of the presented paper was to check the possibilities of application of such kind of modelling and the comparison between current results and investigations of failure rate prediction in another Polish city. Operational data from 12 years of exploitation, received from water utility, were used to predict dependent variable (failure rate). Data (249 and 294 for distribution pipes and house connections, respectively) from the time span 2001–2012 were used for creating the KNN models. On the basis of other data (one case for each year) the validation of optimal model, based on Euclidean distance metric with the number of nearest neighbours K = 2, was carried out. The realization of the modelling was performed in the software program Statistica 12.0.

“…Moreover, with regard to natural conditions, the territory of Central Europe is among areas with a low level of water stress [3,9]. Despite this fact, there are several reasons to consider research into the connection between the lower quality of drinking water supply and the development of municipalities in Central Europe to be topical [10][11][12][13]. An analysis of current influences on insufficient drinking water supply for the inhabitants of small municipalities in the Czech Republic is the subject of our study.…”

Repeatedly occurring droughts in the Czech Republic in previous years have heightened the need to answer questions concerning the provision of drinking water in small municipalities in the context of their development. The goal of the research was to assess what mutual relationships exist between insufficient drinking water supply and the socio-economic level of municipalities with less than 2000 inhabitants. The basis of the study is formed by data collected via a questionnaire survey of the mayors of 2110 municipalities. For the purposes of the analysis, the Drinking Water Supply Threat Index (DWSTI) composite indicator was established. Subsequently, the effect of selected factors on DWSTI was determined via correlation and regression analysis, and results were compared for two size groups of municipalities indicate water supply problems. The digging of new wells for individual needs is seen to be the most significant signal of problems. The absence of water supply infrastructure results in a heightening of the socio-economic deprivation of small municipalities, as it limits new building and becomes a limitation to their development. A solution is possible based on regional or trans-regional financial and managerial support of development together with an active approach on the part of municipalities.
