Ensuring reliable and uninterrupted water supply for the residents of Bucha

The project involves the construction of two water supply lines with a diameter of 250x14.8 m from the hydroelectric power plant in the village of Havrylivka to the hydroelectric power plant on Lesi Ukrainky Street, building 28/1a, in the village of Vorzel. The total length of the pipeline route is 19,960 meters (in 2 strands). Since the pipeline route runs along a rather complex terrain, including taking into account the high-altitude location of the hydroelectric power plants in the village of Havrylivka and the hydroelectric power plant on Lesi Ukrainky Street, building 28/1a, in the village of Vorzel, the project involves the construction of an intermediate hydroelectric power plant in the village of Blystavytsia. Thus, the total route of the water supply lines is divided into two sections. The length of the first section from the village of Havrylivka to the village of Blystavytsia is 11,140 meters and it is planned to build it from pipes with a diameter of 250x14.8 PE100 SDR17. The length of the second section of the water supply route is 8820 meters and it is also planned to build it from pipes with a diameter of 250x14.8 PE100 SDR17. Electrical solutions. The estimated electrical load of the pumping station is 112.5 kW. The estimated electrical load of five wells is 137.5 kW. The power supply of the wells and the hydroelectric power station is planned at the expense of the existing capacities from TP 483 and TP 484 with a capacity of 160 kVA each. Technological accounting of the electricity consumed by the hydroelectric power station in the village of Gavrilivka is carried out by electricity meters NIK 2303 ARTT 1140 with current transformers 600/5, which are installed in the fiberglass shield of the pumping station. The fiberglass shield is installed near the KTP-10/0.4 kV, which is located on the territory of the existing hydroelectric power station in the village of Gavrilivka. Electric lighting is designed for 220 V, portable - powered by batteries. Lighting is adopted in accordance with DBN V.2.5-28:2018 "Natural and artificial lighting". Luminaires with LED lamps are adopted as light sources. Hydroelectric power plant in the village of Gavrylivka: pumping station of the 2nd lift (construction); engineering networks (construction); receiving tank 96 m³ (construction). Hydroelectric power plant in the village of Blystavytsa: pumping station of the 2nd lift, pos. 1 according to the general plan (construction); engineering networks (construction); receiving tank 96 m³ (construction). Ringing of clean water tanks on Volodymyra Kovalskyi St., Bucha, and hydroelectric power plant on Lesya Ukrainka St., building 28/1a in the village of Vorzel. The project provides for a bridge on the New Main from the previously designed water supply structure on Lesya Ukrainka Street in the village of Vorzel to the existing water supply structure DN315 (at the intersection of Bohdan Khmelnytsky Boulevard and Nove Shose Street in Bucha), which is laid from the existing water supply structure on Volodymyr Kovalsky Street in Bucha. The designed water supply structures are planned taking into account existing consumers and prospective connections, based on a throughput of 6,000 m3/day. It is also planned to install wells with fire hydrants on the designed water supply structure. This project also provides for the ringing of the designed water supply structure DN315 with the existing water supply structure DN250, which is laid along Borys Gmyra Street in Bucha, by installing a DN250 bridge. The designed water supply structures are planned taking into account existing consumers and prospective connections. It is also planned to install wells with fire hydrants on the designed water supply system. Groundwater intake from six artesian wells. It is planned to build six water intake wells for the exploitation of the aquifer complex (Cenomanian-Callovian) in the deposits of the Ivanytsia suite of the Middle and Upper Jurassic and the Zagoriv, ​​Zhurav, Burom suites of the Lower and Upper Cretaceous, with a productivity of 40.0 m3/h (960 m3/day). To ensure the operation of the well and the location of technological and electrical equipment above the well, it is planned to build a pumping station of the 1st underground lifting type, with a diameter of 2 m, made of reinforced concrete rings in accordance with TP 901-2-178.91. Structurally, the pumping station above the well is made of unified reinforced concrete elements. The internal diameter of the pumping station is 2.0 m, the height of the working part is 2.1 m. The foundation is a monolithic concrete block, on which the sealed wellhead rests with a column of water-lifting pipes suspended from it. The pumping station has natural ventilation.
