Abstract: The master’s thesis was completed based on the assignment, state regulations, and reference materials. An external water supply system was designed for the administrative and warehouse complex. Based on the analysis, an external domestic, drinking, sewage, and firefighting water supply system was designed. A well was chosen as the source of domestic and drinking water supply for the administrative and warehouse complex. The water supply for the designed administrative and warehouse complex is provided from wells. Four wells are planned for the designed site The internal firefighting water supply system is a ring/dead-end system with a main pipeline diameter of ?80 mm, dry pipe, providing continuous 24-hour water supply to the fire site. To ensure the necessary pressure and flow for the ASPG.V and VPV systems, a firefighting pumping station with a YFP ED125-250/160/149.7-J3-2-K269 jockey pump is designed. The fire water supply systems of the administrative and warehouse complex are ring-shaped ? 76 mm, water-filled, designed from electro-welded steel pipes. The diameters of the pipelines have been determined. The object of the study is the internal and external networks for the administrative and warehouse complex. The subject of the study is the hydraulic operating modes of the networks of the administrative and warehouse complex. The purpose of the study is to determine the calculated water consumption, regulating capacities, diameters of the main network pipelines, and to calculate the pumping stations. Research results. 1. The calculated water consumption has been determined. 2. The necessary pumping stations have been selected. 3. The water supply network, sewerage networks and fire protection networks have been designed. 5. Hydraulic calculations of the networks were performed. 6. Pumping stations were designed (the capacity of the stations and the pressure of the pumps were determined, pumps were selected, hydraulic calculations of the suction and pressure lines inside the pumping stations were performed, and the pump axis marks were determined). 9. An assessment of the environmental impact of the design and construction of internal networks and water drainage was carried out.
