The Condition of Sanitary Infrastructure in the Parczew District and the Need for Its Development

Abstract

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 m 3 /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.

The State and Needs of the Development of Water Supply and Sewerage Infrastructure in the Radzyń District

“…Mains sewerage systems are the best solution for the disposal and treatment of wastewater, however, the possibility of constructing such systems may be limited by many factors, mainly technical and economic. These factors are related to the topography of the terrain, soil and water conditions and the settlement pattern, which is why they are of particular importance in rural areas [Micek et al 2018]. In situations where there are no reasonable grounds for building a mains sewerage network, sanitation programs need to adopt off- The analysis of the survey data shows that in the Radzyń district, the segment of off-mains wastewater treatment systems is gaining in importance.…”

“…The disproportion between the length of the water supply network and the sewerage network indicates that the latter is subsidiary to the former, and that its expansion is strictly dependent on access to a water supply system. Other important factors that hinder the expansion of the sewerage network is its greater technical complexity and the capital-intensity of investment in its construction [Micek et al 2018; CSO 2018].…”

The Condition of the Sanitary Infrastructure in the Bialski District in Poland and the Need for its Development

“…The Surveys carried out in the neighbouring districts show that in Radzyń District, the total length of the water supply network in 2016 was over 880 km and was used by 90% of the district population [Bogusz et al 2020]. In turn, in the Parczew District, the total length of water supply system was 630 km and on average was used by 88% of the population of the district [Micek et al 2018]. Despite the fact that in 2016 the water supply network on the territory of Bialski District was used on average by about 79.2% of the population, the analysis of the collected survey data allows us to assess the condition of the water supply infrastructure in the discussed district as unsatisfactory.…”

“…3). The conducted research allowed determining that in the Bialski District 39.4% of its inhabitants used the sewerage system, on average, while in the neighbouring districts: Radzyń -35% of the population [Bogusz et al 2020] and in Parczew -48% [Micek et al 2018].…”

Status of Water Supply and Sanitation Infrastructure in Opole County (Lubelskie Voivodeship, Poland)

“…However, despite considerable development, the size of the sewerage network in relation to the demand is still very small. In rural areas, especially those with a highly dispersed development pattern, the quantity and quality of sanitation infrastructure can be improved by constructing on-site domestic wastewater treatment plants (Bogusz et al 2020;Jóźwiakowski et al 2017;Micek et al 2018). In the years 2006-2015, the number of on-site treatment plants in Poland increased by 476%.…”
