Opis:
The aim of the study was to compare the various water supply systems – from rural to agglomerations, in terms of continuity of water supply to the inhabitants in a crisis situation. The work included the diversification of water intakes with their number and the maximum daily production capacity and the diversification of water in the water tanks, knowing their number and volume. RB1 and RB2 diversification indexes have been proposed. Assessment criteria were included with comment. The research component is a two-parameter assessment of diversification for selected water supply systems using the indicators proposed by the authors. The use of proprietary indicators to assess the diversification of water supply using preference functions gives the ability to perform calculations easily and accurately.

Opis:
Water is the main source of daily life for everyone and everywhere in the world. Sufficient water distribution depends on the place and design of water tank in certain areas. Water storage tanks are relatively flexible structures and they can tolerate greater settlements than other engineering structures. Deformation of tanks may cause severe damages to tank or even loss of life and injury to people, so monitoring the structural deformation and dynamic response of water tank and its supporting system to the large variety of external loadings has a great importance for maintaining tank safety and economical design of manmade structures. This paper presents an accurate geodetic observations technique to investigate the inclination of an elevated circular water tank and the deformation of its supporting structural system (supporting columns and circular horizontal beams) using reflector-less total station. The studied water tank was designed to deliver water to around 55000 person and has a storage capacity about 750 m3. Due to the studied water tank age, a non-uniform settlement of tank foundation and movement of pumps and electric machines under tank’s body will cause stress and strain for tanks membrane and settlement of sediments. So the studied water tank can tend to experience movement vertically, horizontally or both. Three epochs of observations were done (July 2014, September 2014 and December 2014). The results of the practical measurements, calculations and analysis of the interesting deformation of the studied elevated tanks and its supporting system using least squares theory and computer programs are presented. As a results of monitoring the water storage tank, circular reinforced concrete beams and columns at three monitoring epochs. The body of water storage tank has an inclination to the east direction and the value of inclination is increased with the time.

Efektywność magazynowania ciepła ma wpływ na efektywność energetyczną instalacji ciepłej wody. Do jej zwiększenia przyczynia się utrzymanie rozwarstwienia termicznego w zasobniku ciepłej wody. Zaburzenie stratyfikacji termicznej może być spowodowane między innymi stratami ciepła ze zbiornika do otoczenia. W pracy przedstawiono dynamikę zmian temperatury wody w zasobniku o pojemności 350 dm3, podczas jego wychładzania w godzinach nocnych, na podstawie przeprowadzonych pomiarów temperatury wody magazynowanej na 15 wyróżnionych poziomach. Dla zasobnika obliczono współczynniki strat ciepła dla części górnej, bocznej oraz dolnej, jak również dla całego zasobnika. Uzyskane wyniki odniesiono do wyników badań innych autorów.

Opis:
Water and sediment in ships’ ballast tanks provide habitats for various organisms, and thus facilitate alien species introductions. Ballast tank water and sediment of 19 ships docked in the GRYFIA Szczecin Ship Repair Yard (Szczecin, Poland) located in an area connected with the River Odra estuary (Southern Baltic), were sampled in 2009–2011 to find out if the ships could be vectors of species introductions to the estuary, already known for the presence of non-indigenous taxa. This study showed the ballast water of the ships examined to house rotifers, copepods, cladocerans, and bivalve and cirriped larvae – common constituents of zooplankton assemblages in coastal waters. The ballast tank sediment supported meiobenthic foraminiferans, nematodes, harpacticoid copepods, turbellarians, bivalves, polychaetes, and chironomid and cirriped larvae. It is not possible at this stage to judge what meiofaunal taxa constitute an alien component in the estuary biota. Macrobenthos in the ships’ ballast tank sediment examined was represented mainly by nereid polychaetes. Although the unintended “biological cargo” examined proved quite diverse and abundant, it contained few identified alien taxa. It does not seem likely than any of them could pose a threat of a biological invasion in the River Odra estuary. However, numerous species remained unidentified, and therefore assessment of the risk of alien species introduction and invasion contains a large measure of uncertainty. On the other hand, the risk as such remains, since the density of ballast water-borne organisms in all ships exceeded the allowed limits.

Opis:
The analysis of a solar installation operation was conducted on the example of a detached house in the Lesser Poland province in Poland. A gas boiler and three flat-plate collectors are located inside the house, which are used for heating water in the hot water tank with a volume of 220 dm3. The installation was established in 2012. The heat measured system (for solar gains) was added in 2014. In 2015–2019 solar heat gains measured per area of absorber were higher than 340 kWh/m2. During a two-week period in June 2015, the insolation on the horizontal plane and the temperature were measured in 4 different points of the hot water tank. On this basis, heat losses from the storage tank were determined, i.e. a decrease in temperature during periods with and without the consumption of hot water by the residents. During this period, a temperature higher than 80°C was observed several times in the hot water tank. In two parts of the hot water tank, rhe determined temperature decreases were used to obtain the heat loss amount. In the analyzed period (2 weeks), 9 days were observed with solar heat gains higher than 9 kWh/day. For these days, the value of heat loss from the solar hot water tank was estimated at over 6 kWh/day. This data corresponds to the actual heat demand for hot water preparation in the building at 7.3 kWh/day. The correlation between daily solar heat gains and solar hot water tank heat losses were also determined. In addition, based on the amount of heat losses, the value of the tank loss coefficient was estimated. The obtained value was compared with the manufacturer’s data and reference data.
Analiza aspektów pracy instalacji solarnej została przeprowadzona na przykładzie domu jednorodzinnego w województwie małopolskim w Polsce. W analizowanym budynku jednorodzinnym znajduje się kocioł gazowy i instalacja solarna złożona z trzech płaskich kolektorów słonecznych. Urządzenia te odpowiadają za przygotowanie ciepłej wody użytkowej magazynowanej w zasobniku o pojemności 210 dm3. Instalacja powstała w 2012 roku, w 2014 roku została opomiarowana pod kątem uzysków solarnych. W latach 2015–2019 mierzono uzyski solarne, były one wyższe niż 340 kWh/m2 powierzchni absorbera. Podczas dwutygodniowego okresu w czerwcu 2015 roku mierzono także natężenie promieniowania słonecznego na płaszczyźnie poziomej i temperaturę w 4 różnych punktach zasobnika ciepłej wody. Na tej podstawie określono straty ciepła z zasobnika, tj. spadek temperatury w zasobniku w okresach z i bez poboru ciepłej wody użytkowej przez mieszkańców. W tym okresie zanotowano temperaturę wyższą niż 80°C w zasobniku tylko przez kilka stosunkowo krótkich okresów. Wyznaczone spadki temperatury w dwóch częściach zasobnika ciepłej wody użytkowej użyto do określenia ilościowych strat ciepła. W analizowanym okresie (2 tygodnie) zaobserwowano 9 dni z uzyskami solarnymi wyższymi niż 9 kWh/dzień. Dla tych dni oszacowano wartości strat ciepła z zasobnika na poziomie powyżej 6 kWh/dzień. Dane te korespondują z rzeczywistym zapotrzebowaniem na ciepło do przygotowania ciepłej wody użytkowej w budynku na poziomie 7,3 kWh/dzień. Określono także zależności między dziennymi uzyskami solarnymi a stratami ciepła z zasobnika (korelacja). Ponadto bazując na wielkościowych stratach ciepła, oszacowano wielkość współczynnika strat ciepła z zasobnika. Uzyskaną wartość porównano z danymi producenta i danymi referencyjnymi.

Opis:
The civilization progress entails an increasing demand for water. There are many different technologies for collecting water from alternative sources. An efficient and cost-effective solution is to use small tanks for rainwater runoff from rooftops. In this way, the harvested water can be successfully used to flush toilets, which stands for 30 percent of water consumption in households. The capacity of water tanks depends on the technical and economic possibilities. Using a dual flush system in toilets that allows for both rainwater and mains water usage can lead to a significant reduction in the tank size. In Bielsko-Biała, given its environment, one-family dwellings, a rainwater tank with a capacity of only 0.25 m3 per person and a roof area of 30 m2 per person, it is possible to save almost 80 percent of treated mains water used in toilet flushing. It constitutes over 10 m3 of water per person per year. A nomogram made for choosing the right tank according to the roof area and tank capacity allows assessing the possibilities in terms of drinking water savings in any building in the environment of Bielsko-Biała.

The aim of the work is to present the current state of water and wastewater management in the municipalities where the Polesie National Park (PNP) is located. The PNP is situated in Lublin Voivodeship, in the area of six municipalities: Sosnowica, Hańsk, Urszulin, Stary Brus, Wierzbica and Ludwin. The data used in this paper, were obtained on the basis of the surveys conducted in these municipalities in 2016 by the Department of Environmental Engineering and Geodesy of the University of Life Sciences in Lublin. In the analyzed communes, there was a very large disproportion between the usage of sewerage and the water supply network. It has been shown that 79.1% of the inhabitants living in the afore-mentioned communes used the water supply network and only 22.5% of them used sewerage. In the discussed communities there are 9 collective, mechanical and biological wastewater treatment plants with a capacity of over 5 m3•d-1. On the farms located in the scattered areas, which are not connected to the sewerage, wastewater is discharged mainly to the septic tanks. In four out of the six analyzed municipalities, there were 2345 septic tanks registered. Domestic sewage from some farms is purified in household wastewater treatment plants (395 pieces). The plants with the drainage systems are prevalent (84.9%), which may contribute to the groundwater quality degradation. In order to protect the natural environment within the communes that form the PNP, it is necessary to undertake the actions that will contribute to the improvement of the current state of water and wastewater management. While solving the existing problems related to water supply and wastewater treatment, it is strongly required to adhere to the principle of sustainable development and use highly effective systems in order to ensure that the ecological effects are appropriate.

This paper investigated the problems and impacts of transient flow in pipeline systems due to pump power failure. The impact of different protection devices was presented to assure surge protection for the pipeline system. A model via Bentley HAMMER V8.0 Edition was employed to analyse and simulate hydraulic transients in the pipeline system, and protection alternatives were studied. Surge protection included using only an air vessel, using an air vessel and two surge tanks, and employing five air vessels and vacuum breaker. The obtained results for pressures, heads, and cavitation along the pipeline system were graphically presented for various operating conditions. Using five air vessels with vacuum breaker valve as surge protection proved to be more effective and economical against pump power failure. Changing the flow density did not have a significant impact on the pressures. For protection with an air vessel; it was concluded that the value 40% of the original diameter for inlet pipe diameter of air vessel, and the value of 2/3 of original pipe diameter were critical values for the transient pressures. Cast iron pipes proved to be the best pipe material for all studied volumes of the air vessel. For protection with an air vessel and two surge tanks; as the inlet pipe diameters increased the maximum pressures increased and the minimum pressures decreased. Regression analyses were performed obtaining equations to predict the pressures according to the inlet pipe diameter, the area of surge tank, and the pipe diameter.

The aim of this paper is to present the current state of water and sewage management in the communes where the Roztocze National Park (RNP) is located. The park is located in Lubelskie voivodship, in the territory of four communes: Zamość, Zwierzyniec, Adamów and Józefów, while its buffer zone is located in the communes of Krasnobród, Tereszpol and Szczebrzeszyn. The paper uses data from surveys conducted in these municipalities in 2016. On average, 68.9% of the population used the water supply system in the municipalities surveyed, while 33.4% of the inhabitants had the possibility of discharging sewage to the sewerage system. In the area of the communes, there are 10 collective, mechanical and biological wastewater treatment plants with a capacity exceeding 5 m3·d-1. The households which are not connected to the sewage network discharge wastewater mainly to non-return tanks. Four out of the seven surveyed communities had 64 domestic sewage treatment plants, including 60 systems with infiltration drainage, which do not ensure high efficiency of removing pollution and may even contribute to the degradation of groundwater quality. In order to solve the existing problems in the area of sewage and water management occurring in the communes where the Roztocze National Park is located, it is necessary to further develop collective sewage systems and equip the areas with dispersed buildings with highly efficient, residential sewage treatment plants, e.g. constructed wetlands.

The aim of this paper is to present the current state and the need for development of sanitary infrastructure in the communes of Parczew District, in Lublin Voivodeship. Parczew District encompasses seven communes: Parczew, Dębowa Kłoda, Jabłoń, Milanów, Podedwórze, Siemień, and Sosnowica. The present paper uses the data from the surveys conducted in these communes in 2016. On average, 88% of the population used the water supply system in the communes surveyed, while 48% of the inhabitants were connected to a sewerage system. Parczew District had 12 collective mechanical and biological wastewater treatment plants with a capacity exceeding 5 m3/d. The households which were not connected to the sewerage network discharged the wastewater mainly to non-return tanks. In the communes surveyed, 1,115 households had domestic wastewater treatment plants. All of them were systems with infiltration drainage, which do not ensure high efficiency of removing pollutions and may even contribute to the degradation of the groundwater quality. In order to solve the existing problems of sewage and water management in the communes of Parczew District, it is necessary to further develop the collective sewerage systems and equip the areas which have a dispersed development layout with highly efficient domestic treatment plants, such as constructed wetlands.
