The purpose of this work is to study the operation of water supply and drainage systems, improving the methods of calculation of elements and methods of water purification, foundations and foundations of hydraulic structures. Research methods - theoretical research, improvement of models, modeling of processes, improvement of calculation methods. The efficiency of natural water purification by the method of dynamic ultrafiltration is confirmed. A regularity is determined that determines the dose of coagulant depending on the color of the water. Recommendations for applying a dynamic layer on the surface of the ultrafiltration membrane substrate have been developed. The analysis of regularities of biological treatment technology with membrane separation for treatment of urban and industrial wastewater is carried out. A method for determining the values of leakage of coolant and water from municipal utilities has been developed. The method of determining the dependence of lowering water levels in group water intake wells on a number of factors has been improved.The variational method of boundary elements for VAT calculation of water-saturated bases has been improved. The factors influencing the hydraulic particle size are determined, the dependence of the cleaning effect on the settling time is established. A model has been developed that takes into account the pulsed mode of operation of ionizers and selects the required values of ion emission.
