    Opis:
    W artykule zawartym w niniejszej zbiorczej publikacji pt. "Mapy ryzyka funkcjonowania rozległych systemów technicznych" przedstawiono idę stosowania i rozpowszechniania technicznych map ryzyka. W niniejszym opracowaniu przedstawiony został przykład zastosowania niniejszych map dla systemu zaopatrzenia w wodę miasta Płocka.
    Risk maps of technical systems functioning make up new approach to reliability issues. In applied so far approach they had a form of statistical analysis based on statistical data. However risk maps make up the dynamic image (like functioning technical arrangement) of technical risks connected with the given technical system. The technical risk map illustrates distribution (profile) of technical risks for the analysed technical arrangement, resulting from the exact analysis of individual technical risks caused by technical internal and external threats occurring in the given technical system. The example of technical risk maps application for the water supply system in Płock is presented in this paper. Analysis presented in the paper was based on six coefficients of expert assessment to which probabilities of their occurrence and costs of results caused by these coefficients (technical risks) were assigned. Applied coefficients are: - possibility of fracture or break of water pipe, - possibility damage on connections of water pipes, - possibility of corrosive damage of water pipe, - possibility of damage on armature of water pipe, - possibility of damage of fire hydrant, - other possibilities of damages not classified in above mentioned coefficients. Analysis was also based on the basic reliability coefficients of the water supply system which were presented in tabular form. Analyses of created during research risk maps showed that used during research expert coefficients (technical risks) not fully described technical threats influencing on the water supply system. However they allow to state: o technical risks directly connected with the water-supply network cause threats with quite big frequency and moderate financial results, o level of the risk of failure appearance, damage of the water supply system, diminishes along with increasing distance to key, integral elements of the system, such as: pumping stations, zone pumping stations, equalizing reservoirs, o enlargement of the level of failure appearance risk exists in water-supply rings with compact shape. This is a result of enlargement of technical armature occurrence thicknesses in the given area, water-supply pipes with bigger diameters cause growth of the level of failure appearance risk. This is caused by enlarged cost of failure effects removal on this type of water pipes, ring networks in relation to ramified networks are characterized with lower level of technical risk of failure appearance, which is caused by construction of these systems, sensitivity of risk map directly influences on possibility content-related evaluation of gained results

    Opis:
    Celem pracy jest modelowanie wybranych parametrów sieci wodociągowej miasta Łapy oraz symulacja zamiaru podłączenia nowych ujęć dla różnych wariantów lokalizacyjnych. Jako obiekt badań wybrano sieć wodociągową miasta Łapy o liczbie mieszkańców 2300, zasilaną z trzech ujęć. Średnie dobowe zużycie wody wynosi 1383 m3/d. Większość wody zużywana jest przez mieszkalnictwo oraz tereny przemysłowo-składowe.
    The aim of the work was modeling of selected parameters of the water supply system of Łapy city and simulation of intention of connecting new intakes for various location variants. Water supply system of Łapy city with 2300 inhabitants supplied from three intakes was the object of investigations. Average day usage of water is 1 383 m3/d. Majority of water is used by housing and industry and storage terrains. In the first phase of creating the model digital map of Łapy in the scale 1:500 was used and following layers were marked off: net of water supply conductors, borders of plots and buildings. On the base of created map exact values of length and diameters of sections of water supply system and ordinates of individual elements of water supply system were obtained. In order to asses water usage records of readings (years 2006 and 2007) from all water meters located on the water supply system, of total 2056 objects, were taken. In order to verify values pressure in created model of water supply system [1] data loggers of pressure and temperature Cellbox-H were located on selected underground hydrants. Measurements gathered this way were used for comparison and calibration of pressure in given points of net obtained using the model and using real values from data logger. Utilization of measurements of water usage within one year in studied municipal enterprise allows to model average day water demand on the water supply system [2]. Modelling water pressure on the individual sections of water supply system is possible thanks to suitable introduction of data about studied system to programme executing the hydraulic simulation on the base of digital map of the city. In order to obtain credible results it is indispensable to start model on the basis of values of average day water usage and verification of obtained thanks to model pressures with measurements from data logger. Than calibration of model on the basis of executed measurements should be conducted, and next simulation of work in various conditions should be made.

    Opis:
    Powierzchnia naszej planety w ponad 70% pokryta jest wodą, przez co stwarza się wrażenie o powszechnej obfitości wody na Ziemi. Jednakże dla oceny zależności naszego bytu od zasobów wodnych jest istotna dostępna ilość świeżej (słodkiej) wody. 97,5% wszystkich zasobów wód na Ziemi stanowią wody słone oceanów, mórz, części jezior i wód podziemnych. Zasoby wody świeżej stanowią więc zaledwie 2,5% światowych zasobów i w prawie 70% występują one w zlodowaceniach Antarktydy, Grenlandii, obszaru Bieguna Północnego i w wyższych partiach gór. Stąd też ilość świeżej wody, dostępna dla ludności do bezpośredniego spożycia stanowi mniej niż 1% światowych zasobów (0,7%) [1, 8, 10, 13, 19, 33, 76].
    The commonly held belief that there is widespread abundance of water on Earth, is grossly exaggerated. It comes from the fact that 70% of our planet is covered with water. However, the amount of accessible fresh water to satisfy our living needs constitutes less than 1% of world resources. Moreover, only this amount of water is regularly renewed by the ecosystem in the form of rainfall and snowfall. Water resources vary depending on the region: Middle East and South Affrica - 1000 m3 per person per year, Poland - 1460, Europe - 4560, World-7400, Central America - 23 900. Regions particularly deficient in water resources are the Middle East, South Africa, Poland and a number of regions in Europe. This inequality in accessibility of fresh water resources leads to a lot of cross-border tension and conflicts. According to the UNESCO report this situation may lead to many wars over water in the near future and may pose a threat to world peace. The Framework of the UE Water Directives from 2000 obligates membership countries to ensure that by 2010 they have implemented balanced policies concerning water consumption. The arrangements of the EU Water Directives were implemented in Poland in 2001 under The Water Law Act. During the 20th century the world population increased almost three times, whereas water consumption increased sevenfold. According to the statistics of the UN from 2001 the world population will increase from 6.8 billion at present to 9.8 billion by 2050. At the same time, according to the most optimistic prognosis the population in Poland will decrease from 38.5 to 36.6 million accordingly, and by the most pessimistic prognosis to 29.6 million. Simultaneously, a very unfavorable change in the structure of Poland's population will take place as a result of the process of ageing. The WHO and UNICEF estimates from 2004 state that 1.1 billion of the world population did not have any access to fresh water. At the same time 2.6 billion did not have proper sanitary conditions. It resulted in 5 million deaths per annum. Daily water consumption per capita in the most developed countries was equal to monthly water consumption per capita in the economically underdeveloped countries. It has been commonly agreed that water should be considered as a universally accessible natural resource. The poorest who cannot afford to pay for water consumption should be subsidized. The population of our planet will have a chance of surviving, providing people learn how to live without wasting water resources and how to manage them rationally and economically. Water safety should be given the same recognition and priority as electrical safety.
