    Opis:
    The paper presents the current state of water supply and sewerage infrastructure and the need for its expanding in Radzyń district. The district is located in the northern part of Lublin Voivodeship in Poland. The following communes belong to Radzyń district: the municipal commune of Radzyń Podlaski and 7 rural communes: Borki, Czemierniki, Kąkolewnica, Komarówka Podlaska, Radzyń Podlaski, Ulan-Majorat, Wohyń. The data show that the water supply network in Radzyń district is well developed. The most significant percentage of the population using the water supply network has the rural commune of Radzyń Podlaski – 99.9%, while the smallest, commune Komarówka Podlaska – 54.5%. The survey showed that there was a very large disproportion between the development of the sewerage and water supply systems. The largest percentage of the population using the sewerage network has the municipal commune of Radzyń Podlaski – 99.7%. The smallest percentage of users of collective sewage disposal systems was recorded in the rural commune of Radzyń Podlaski (7.2%). The commune of UlanMajorat does not have a sewerage system. The survey conducted in 2016 shows that 8 collective wastewater treatment plants operated in Radzyń district at that time. The total capacity of the treatment plants is over 5,300 m3/d. In 2016, Radzyń district had about 1,000 household wastewater treatment plants. The presented data show that the condition of the sanitary infrastructure in rural communes of Radzyń district is unsatisfactory and requires the investment activities mainly aimed at expanding collective sewage disposal and treatment systems as well as developing a network of household wastewater treatment plants.

    Opis:
    The aim of this paper was to present the current state and the need for development of the sanitary infrastructure in the communes of the Bialski District located in the Lublin Voivodeship. The Bialski District encompasses 2 urban communes: Miedzyrzec Podlaski and Terespol and 17 rural communes: Biała Podlaska, Drelów, Janów Podlaski, Kodeń, Konstantynów, Leśna Podlaska, Łomazy, Międzyrzec Podlaski, Piszcząc, Rokitno, Rossosz, Sławatycze, Sosnówka, Terespol, Tuczna, Wisznice and Zalesie. The present paper uses the data from the surveys conducted in these communes in 2016. On average, 79.2% of the population used the water supply system in the surveyed communes, while 39.4% of the inhabitants had the possibility of discharging wastewater to the sewerage system. In the area of the communes, there were 20 collective, mechanical and biological wastewater treatment plants with a capacity exceeding 5 m3/d. The households which were not connected to the wastewater network, discharged wastewater mainly to non-return tanks. In the surveyed communes, there were 4437 household wastewater treatment plants. Most of them (above 80%) were the systems with infiltration drainage, which do not ensure high efficiency of pollutants removal and may even contribute to the degradation of the groundwater quality. In order to solve the existing problems of wastewater and water management occurring in the communes where the Bialski District is located, it is necessary to further develop collective wastewater systems and equip the areas characterized by dispersed housing with highly efficient household treatment plants, e.g. constructed wetlands.

    Opis:
    The paper presents an evaluation of the pollutant removal efficiencies of four primary settling tanks that were components of on-site domestic wastewater treatment plants located in the Roztocze National Park in Poland. We studied two four-chamber settling tanks which were elements of the technological lines of activated sludge treatment plants, and two threechamber settling tanks which provided primary treatment in hybrid constructed wetlands. The tests were conducted in the years 2017–2019. During this period, wastewater samples for analysis were collected from the first chamber (raw wastewater) and the last chamber (primary settled wastewater) of each settling tank. We tested the following pollution parameters: total suspended solids (TSS), BOD5, COD, total nitrogen (TN), and total phosphorus (TP). The following mean pollutant removal efficiencies were obtained for the four-chamber settling tanks: TSS – 68.3%, BOD5 – 50.4%, and COD – 49.5%; the three-chamber settling tanks were much less efficient at reducing those pollution parameters: 50.9%, 17.0%, and 2.3%, respectively. Neither the three-chamber nor the four-chamber settling tanks ensured effective elimination of biogenic compounds. In most cases, the concentrations of TN and TP in primary settled wastewater were higher compared to raw sewage, which means that these elements were being released from sewage sludge during treatment. Despite this finding, the study shows that a primary settling tank should be used as a basic component of any domestic wastewater treatment plant, as it ensures a considerable reduction in TSS and organic matter.

    Opis:
    The work presented the assessment of household wastewater treatment plants with drainage systems on the quality of groundwater in dug wells and deep water wells in the area of 3 selected communes (Drelów, Dębowa Kłoda and Urszulin), located in the Lublin province in south-eastern Poland. The investigations of the physicochemical composition of water from selected 28 dug wells and 2 deep water wells were conducted from June to July 2020, involving 9 measurement series. The microbiological studies consisted in 4 measurement series. The composition of the wastewater from primary settling tanks discharged to soil via drainage systems located in the vicinity of considered wells was also examined on a single occasion. The studies indicate that the water from wells are significantly polluted with ammonia, nitrites, as well as compounds of natural origin: iron and manganese. The presence of microbiological pollution of fecal origin was noted. The studies clearly indicate the possible pollution of the analyzed well waters with domestic sewage discharged to soil via drainage systems. Therefore, it necessary to take the actions aimed at improving the quality of groundwater in the Lublin province, including limitation of drainage systems, especially in the areas with unfavorable subsurface and hydrological conditions as well as low water supply coverage. The need to introduce changes in legal regulations and strategies for the development of technical infrastructure in counties, favoring the most efficient, as well as simple and inexpensive technologies, was indicated.
