“…For the assessment of diversification the following parameters were proposed: Q -parameter associated with the resource of water in the water supply subsystems (WSS) [31], V-parameter associated with the volume of water in the network water tanks [32,33], M -a parameter related to flow ability of pressure pipelines of the second degree pumping station [15,24].…”

The subject of the publication is the presentation of a methodology for determining the degree of diversification of water resources in collective water supply systems (= CWSS). Knowing the number of subsystems for water supply and their share of total water production, it is possible to calculate the dimensionless Pielou index. Similarly, the diversification indicators for networked water tanks (number and volume) and pressure pipelines of the second degree pumping station (number and flowability) can be determined. The work presents the calculation of diversification indices for selected CWSS in Poland. The presented methodology gives the possibility of three-parameter evaluation of settlement units with different water demand and different technical structure.

“…The analysis conducted is helpful, as emergency-response plans are developed; and as decision-making is engaged in, with regards to the need to implement corrective actions and develop future goals in terms of modernization or system expansion, so that the safety of gas supply is assured [35,36]. A very important issue is to predict threats affecting the loss of system security, taking into account failures or undesirable events that could cause a domino effect, or so-called cascade failure [37,38], via implementations of economical and reliability criteria for the integrated safety assessment [39][40][41][42][43][44].…”

The development of appropriate methods by which to assess the functioning of gas pipelines helps limits the consequences of disasters, in that way protecting users better. Assessment methods of this kind are presented in this paper, which advocates the integrated risk area identification method. The risk taken account of is understood to be a function of the probability or frequency of occurrence of undesirable events, and comes with parameters defining the consequences of these events, should they arise, in terms of their magnitude. The level of system vulnerability to events of these types is a factor considered, and the risk calculation is of a kind that encompasses both quantitative and qualitative aspects. The approach taken is regarded as a quick and simple risk-assessment tool applicable to the daily operation of gas networks for a gas company. Specifically, the framework of the research carried out extends to: (1) Estimation of the average cost of failure of gas pipelines in the case of an urban agglomeration in SE Poland; (2) assessment of the level of integrated risk facing the gas-supply subsystem, by reference to the risk area identification method; (3) failure forecasting by way of regressions with delay; and (4) conclusions regarding failure risk assessment in a gas-supply network, as well as a consideration of prospects. The framework referred here, thus constitutes the basis for both analysis and assessment of the safety of a gas-supply system.

Abstract. The subject of the publication is the analysis and assessment of failure rate of the water supply network in a district city located in southeastern Poland. The analysis was based on the failure rate index. In addition, the paper uses the Bayes theorem to determine the probability of failure of water supply network. The exploitation data obtained from the water supply company were used in the work. It was found that the water supply network of the analysed city is characterized by good technical condition.
