“…The energy of water that is needed to generate electricity is obtained by using either the natural flow of water in rivers, or the difference in levels between the channel in which water flows further and the water stored in reservoirs or lakes. Another possibility of acquiring hydroenergy are the movements of oceanic waters [4]. The first attempts to create electricity with the help of wind had already taken place in the nineteenth century, but it was not possible to implement it on a large scale.…”

The increase in energy consumption in the world, with the decreasing resources of conventional energy, is increasingly leading to campaigns aimed at limiting the acquisition of energy from non-renewable sources to intensify the use of alternative energy sources. The paper presents the possibilities of obtaining heat energy using a heat pump for heating purposes, ventilation and hot water preparation. Hot heat sources for the heat pump are discussed and their energy possibilities in relation to the geographical conditions of the territory of Poland. Variants of heat pump cooperation with renewable sources in the form of air, soil and water were adopted for analysis. Two cases of co-operation of the ground collector with the heat pump are also considered, in the form of vertical and horizontal wells of the heat exchanger type. Based on the known methodology of seasonal heat demand, the final and primary energy consumption was determined for each analyzed case together with auxiliary energy. Based on the calculations carried out, the final emission of carbon dioxide was determined for individual cases and they were compared with the emission that would be generated when producing heat using a gas boiler and heating network.

“…However, if water intake is shut off, the volume of water stored in tanks assumes a key role [15,16]. Collective pressure pipelines associated with second-degree pumping stations, whose number and diameter affect the of water supply, are also of importance [17][18][19][20][21][22]. In turn, a reduced water supply, or total lack of water, can threaten the lives or health of water consumers, with financial losses among both recipients and water companies also possibly arising.…”

The approaching prospect of obligatory implementation and pursuit of Water Safety Plans forces water companies to reflect on supplies in crisis situations that, for example, relate to the closure of a basic intake, or scarcity of water due to climates changes (droughts). Where supplies are diversified, there can be greater certainty as to the continuity of good quality supply, even in an emergency. As one of each country’s systems of critical infrastructure, the collective water supply system (CWSS) should be protected, with the diversification of supply treated as a basic tool to raise levels of security among consumers. This article, therefore, presents a method from the authors’ by which diversification may be assessed, including by reference to basic and key elements of the CWSS capable of affecting the continuity of water supply. Sample calculations using the proposed method are also presented here for selected Polish cities. In the event, as only one Polish CWSS can be assigned to the category representing excellent diversification, the suggestion is clearly that Poland’s systems must still progress with the diversification of water supply, in order to further reduce the risk of water shortages.

“…A useful construct has risk analysis divided into the two components of assessment (identifying, evaluating, and measuring the probability and severity of risks) and management (deciding what to do about those risks) (Haimes 2004 ; Szpak and Tchorzewska-Cieslak 2015 ). Risk analysis for technical systems is now highly developed and used i.a.…”

A new concept for risk analysis relating to the degradation of water reservoirs

This paper presents a proposal for a procedure by which to analyse the risk of reservoirs being degraded. The body of water assessed for its susceptibility to degradation in line with the proposed procedure is Myczkowce Reservoir, SE Poland. This reservoir has a maximum capacity of ten million m3 and helps provide hydropower, by serving as a surge tank located above the main Solina Reservoir. On the basis of an assessment of its morphometric and hydrological parameters, Myczkowce Reservoir was assigned to the low-resilience category where risk of degradation was concerned. The primary factors responsible for that are limited capacity in relation to shoreline length, a lack of thermal stratification, and a high value for the Schindler index. These and other environmental parameters provided for Myczkowce’s assignment to the category of susceptible to the impact of matter supplied by its catchment, with this reflecting the instantaneous nature of the basin, high values for the Ohle coefficient, average catchment slope, and the lack of a septic system. The designated risk level supported Myczkowce’s assignment to a category characterised by an “unacceptable” risk of degradation. The proposed method taking two parameters (resilience and susceptibility) into account represents the first universal method for assessing reservoirs without reference to risks such as drought, flooding, or lack of water supply for human consumption. The risk depends only on the reservoir and catchment parameters.
