COMPREHENSIVE TECHNICAL SURVEY OF TREATMENT FACILITIES FOR RECONSTRUCTION OF URBAN WATER SUPPLY SYSTEMS
Modern and corresponding to the entire necessary requirement water treatment facilities should be in every settlement. And the state of ecology in the surrounding area will depend on how well these systems perform the functions assigned to them. Untreated liquid waste can cause bad consequences, the death of flora and fauna, soil contamination, as well as people. Reconstruction, technical re-equipment, renewal of water treatment and water disposal facilities are an important and logically justified process for the development of improving the efficiency and safety of water purification technology for its subsequent consumption by the population. This is due to changes in the living conditions, with scientific and technological progress, with an increase in the norms and rules requirements for the efficiency, quality and safety of the purification and water treatment process, a decrease in energy consumption for the structure operation and the transition to alternative and safe energy sources. Water treatment and water disposal facilities reconstruction consists in full or partial changes of their structures, modernization and improvement of technological processes at water treatment facilities, replacement of outdated main and auxiliary equipment with modern ones. Reconstruction justification of water treatment and water disposal facilities is carried out due to a full comprehensive technical survey of structures, main and auxiliary engineering equipment, their performance, efficiency and safety. The comprehensive technical survey results make it possible to determine and select technically and economically viable solutions for the modernization and reconstruction of water treatment and wastewater disposal facilities. The paper presents the comprehensive technical survey results of a treatment facilities block in a water treatment plant, identified defects and damage affecting the structures bearing capacity, performed a design justification of the structures technical condition, proposed methods for eliminating the identified defects and damages within the planned reconstruction of water treatment facilities.
