Abstract

The article analyzes the coverage of water supply and sanitation services among the rural and urban population of Karaganda region; presents data on the length of networks and their technical condition, as well as the effectiveness of water disposal system facilities. The aim of the work: to study the degree of coverage of water supply and sanitation services and their technical condition among the rural and urban population of Karaganda region for the period 2010-2020. Retrospective analysis of secondary data with a depth of 10 years, form: “On the work of water supply and sewage facilities in the Republic of Kazakhstan”. Among 421 rural settlements of the region – 245 are provided with the centralized water supply (89,9%), 166 with the decentralized water supply (9,9%) and 8 with the transported water supply (0,2%). Coverage of the centralized water supply in urban areas of the region is 98%, coverage by the centralized sewage system is 78.43%. The length of water supply networks in rural areas tends to increase with an increase of 80.5%, the drainage system also increased by 81.2%. In urban areas, the length of networks remained unchanged. The coverage of the rural population with central water supply and sanitation significantly increased during the study period. The results of the research indicate that at present there is a significant imbalance between the provision of the population with centralized water supply and centralized water disposal. The technical condition of water supply and sewerage networks in rural areas remains at an unsatisfactory level, which leads to high losses and deterioration of drinking water quality.
