Opis:: In this study, the current operation efficiency of the wastewater treatment plant (WWTP) in the city of Kłodzko in the Lower Silesia Voivodeship (Poland) was analyzed and the predicted amount of the wastewater flowing to the WWTP in a 20-year period (until the year 2036) was estimated. The data on the quality and the quantity of raw (entering to the WWTP) and treated sewage from the years 2012-2016 were analyzed. The five essential pollutants indicators: biochemical oxygen demand (BOD₅), chemical oxygen demand (COD_Cr), total suspended solids (TSS), total nitrogen and total phosphorus, regulated in the water permit were used to evaluate the efficiency of contaminants removal. On the basis of the percentage reduction of the individual pollutants indicators and their acceptable concentrations in the treated sewage, the effectiveness of the operation of the object was determined. Furthermore, a so-called the treatment plant reliability factor (RF) was calculated and its value below 1.0 indicates the correct operation of the wastewater treatment plant. After determining the prospective amount of raw sewage in 2036 (based on the decreasing population in the city) it has been found that the WWTP will work with a significant reserve of capacity and the modernization of the treatment system, leading to a decrease of its capacity should be considered.

Opis:: At the current stage of discharge and treatment of municipal sewage and other types of wastewater in the territory of Ukraine, traditional technologies of biological treatment in aero-tanks by the process of aerobic oxidation involving active silt characterized by low efficiency are largely used. It was established that biological treatment and additional treatment of sewage involving hydrophytes are efficient. The research on wastewater quality and the efficiency of sewage treatment was conducted in three phases: Phase 1 – “the quality before treatment”, Phase 2 – “the quality after mechanical-biological treatment” at the existing municipal treatment plants, Phase 3 – “the quality after additional treatment by hydrophytes”. In order to determine the efficiency of using hydrophytes additional treatment, Eichhornia crassipes (water hyacinth) and the perennial aquatic plant Lemna minor were planted in one treatment pond. The results of the experiment made it possible to determine high efficiency of using hydrophytes for additional sewage treatment. In particular, the efficiency of additional treatment in the treatment ponds removing the residue of suspended pollutants for 40 days was 32%, toxic salts – 13.0–23.0%, oil products – 30.0%, biogenic substances – 68.5–83.3%. It caused a drop in the values of chemical and biological oxygen demand for 5 days by 89.6% and 61.2%, respectively. The efficiency of sewage treatment removing toxic salts and oil products reached 97.7%, whereas in the case of mineral and organic pollutants – up to 99%. That contributed to a considerable increase in the wastewater quality by the criteria for fisheries. In particular, high nutritional value of Eichhornia crassipes and Lemna minor allowed obtaining 12.5 tons of hydrophyte wet mass that can be used as green manure, feeds for farm animals, poultry and fish.

Opis:: The paper describes the status of water supply and sanitation infrastructure in the Kraśnik County. The description is based on the official statistical data and the data obtained in a survey carried out in 2016. The Kraśnik County is located in the Lublin Province and comprises 10 communes: one urban commune (the Municipality of Kraśnik), two urban-rural communes (Annopol and Urzędów), and seven rural communes (Dzierzkowice, Gościeradów, Kraśnik, Szastarka, Trzydnik Duży, Wilkołaz, and Zakrzówek). In 2016, an average of 90.9% of the County’s inhabitants had the access to the mains water, but only 13.5% were connected to the mains sewerage. The County has six centralized wastewater treatment plants with a total capacity of approximately 14.164 m³/d. The survey data showed that the records of cesspools were kept in only four of the County’s communes: the Municipality of Kraśnik, Urzędów, Wilkołaz, and Zakrzówek. The total number of cesspools in those communes was 4776. The Kraśnik County is in great demand for the construction of on-site domestic wastewater treatment plants, which are an excellent alternative to cesspools. The network of domestic wastewater treatment plants in the Kraśnik County is made up almost entirely of systems with a drainfield, which may pose a serious threat to the soil and water environment. The results of the present study suggest that Commune Offices must take decisive steps to eliminate the existing disproportion between the coverages of the sewerage and water supply systems in the County’s communes.

Opis:: 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.

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 Ryki District located in the Lublin Voivodeship. The Ryki District encompasses 1 urban Commune – Dęblin, 1 urban-rural Commune – Ryki and 4 rural communes: Kłoczew, Nowodwór, Stężyca and Ułęż. The paper is based on the data from the surveys conducted in all the afore-mentioned communes in 2016. In the whole district on average 71.3% of the population used the water supply network, while 42% of the inhabitants were able to discharge wastewater to the sewage system. Within the area of the Ryki District, 5 collective wastewater treatment plants with a capacity exceeding 5 m3/d functioned in 2016. The households which were not connected to the sewage network discharged wastewater mainly to non-return tanks. About 440 household sewage treatment plants were found in the surveyed communes. The overwhelming majority of such small objects in the discussed district were activated sludge systems (92%). The research carried out in 2016 proved a strong need to develop the current state of the sanitary infrastructure in the Ryki District. A particular emphasis should be placed on the wastewater management by connecting the inhabitants of urban areas to a joint sewage disposal system. Ecological awareness must be raised so as to encourage people to invest in household wastewater treatment plants, which should be used in the areas with scattered development.

Opis:: 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.

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.

Opis:: The Cisadane River, Tangerang City, is one of the most important rivers in Indonesia. This river provides raw water for Municipal Waterworks (PDAM) of the Tangerang City and Soekarno-Hatta International Airport, but the water quality tends to deteriorate due to pollution. The government has made various efforts to manage the river water quality, but no significant resolution was issued yet. The problem is becoming more complicated due to land-use changes that affect the pollutant load. Therefore, more precise, integrated, and comprehensive management is needed. This study used an approach with various methodologies according to the stages of the research, including; qualitative and quantitative analysis, GIS, statistics, risk management, and System Dynamic. The outcome of this research was the development of the policies in river water quality management, specifically land use manage-ment, separation of drainage channels from domestic sewage channels, enhancement of Wastewater Treatment Plant (WWTP) services coverage, as well as reinforcement of institutional and regulatory aspects, especially in funding commitments.
