STATUS OF GIVING-DISTRIBUTIVE COMPLEX OF THE CITY WATER SUPPLY SYSTEM
Keywords:water supply system, giving-distributive complex, water network, hydraulic calculation, piezometer chart
We have calculated the key water intakes in different points of the system with the purpose of determination of the real load flow in the water supply system of the area of influence of water supply of city. We have proposed to develop the equivalent mathematical model of the supply and distribution complex in a number of stages and described in details each of the stages. For the purpose of modeling of work of the separate area of the water supply system of Poltava we have built the tree diagram of the system and carried out the computer based hydraulic calculation of the supply and distribution complex for the maximum water consumption. As a result of the mathematical modeling of work of the water supply system city of Kremenchug we have carried out the hydraulic correlation of system of the supply and distribution complex for the stated periods, defined the overloaded points of the water supply system, found the location of the the most distant consumer, calculated the water flow rate in water supply lines and carried out comparative analysis of the designed and factual flow rates at the control points of the system for the purpose of determination of conformity of the performed modeling of work of the water supply system in “Hidro” software application. Visual reproduction of the obtained results is made in the form of piezometer charts built in "KOMPAS-3D V15" CAD system. The piezometer charts are built on the schema of the main water supply network at a scale of 1:20000. The piezometric lines are drawn through the piezometer charts with at a pitch of 1 meter. The piezometer charts on the areas are determined with the help of interpolation. It is concluded that the main water supply network has sufficient throughput, and the pump stations provide the supply of the required amount of water.
