DEVELOPMENT OF THE SCHEME OF OPTIMIZATION OF WORK OF THE COMBINED MAIN COLLECTOR “KNS-5 – KNS-4” OF THE CENTRALIZED DRAINAGE SYSTEM OF THE CITY OF KHERSON

Abstract

The article presents a scheme for optimizing the operation of the combined main collector KNS-5 – KNS-4 of the centralized drainage system of the city of Kherson. The urgency of modernization and development of drainage is presented. These are issues that need to be addressed immediately. The purpose of the research on the possibility and expediency of developing a scheme for optimizing the operation of the drainage system of the city of Kherson. Quantitative characteristics of the existing main sewage pumping stations in the city of Kherson are presented. The technological scheme of sewage pumping and the city drainage system are given. The characteristics of sewer networks, their length, material, wear are presented. Water consumers and wastewater discharge to the sewer collector area are given № 22. The distribution of wastewater discharge volumes by consumer categories is calculated. Tariffs without VAT for centralized sewerage services approved for 2021 are presented. The scheme of the combined section of the sewer collector “KNS-4 and KNS-5” and its tracing are given. The detailed characteristic of two threads of pressure pipelines from KNS-5 is executed. Presented length, material, year of construction. The characteristic of the collector № 22 (number of serviced residential buildings and population, length, material) is given. The results of certification of the sewerage network are presented. The analysis of the current state of the sewerage network is revealed, a number of shortcomings and remarks are revealed. Analysis of the hydraulic calculation of the reconstructed combined section of the sewer collector № 22 during the transportation of the theoretically justified maximum second flow revealed a number of remarks. The normal mode of operation of the distribution system of drainage is offered. Opportunity to provide, subject to the implementation of the above measures for its reconstruction.
