Wastewater treatment plant, network, road construction in Dabas

The Dabas City Municipality in Hungary from Europe region had released this tender for Task: Development of the sewage disposal and treatment system of the city of Dabas under a business contract, and conducting a minimum 6-month trial operation, performing the tasks covered by the warranty during the warranty period. The construction plans for the sewage treatment plant and network development to be established were prepared under the KEHOP-2.1.3-15-2022-00105 subsidy contract, therefore the FIDIC “Red” Book contract structure will be applied. A preliminary examination procedure was required for the entire investment, which was concluded with a resolution (PE/KTHF/00172-15/2024. - conducting an environmental impact assessment is not required). PART 1: Construction of a wastewater treatment plant and a poplar irrigation plant, network construction tasks a.) Construction of a wastewater treatment plant: The new plant will be built on the outskirts of Dabas, on the plot with the number 0148/5-8 hrsz, as a new, greenfield investment. The planned new wastewater treatment plant will treat the wastewater of the city of Dabas, its organic matter capacity is 30,670 PEE, and its treatment capacity is 3100 m3/day. Several different structures, buildings, and technological facilities are being constructed in the planning area. SBR wastewater treatment technology will be used at the new plant. b.) Establishment and renovation of a poplar irrigation plant The new poplar irrigation plant will include a new poplar irrigation plant, which ensures the final disposal of the treated wastewater. The design documentation includes a treated sewage main channel, a pressure pipeline, poplar tree ridges, irrigation trays, drain pipes and a bypass branch. In addition to the existing 21.5 ha of poplar trees, an additional 27.5 ha of poplar tree wastewater irrigation will be established. In addition to the construction of new drainage ditches, the restoration of the current, heavily degraded trays will be carried out on a scheduled basis. c.) Construction of sewer network and shafts (from control shafts 1 and 2 to the wastewater treatment plant) (Not affected by the trial operation) The fundamental task of this work section is to solve the problem of transferring the wastewater volume arriving via the currently operating 4 collector pressure pipelines towards the new wastewater treatment plant to be established. Within this framework, the following canal sections will be built: the new end lifting shafts, the pressure-type canal sections connecting the current collecting pipes (water control shafts), the pressure-operated collecting backbone pipes (twin pipes) connecting the new end lifting shafts and the planned new wastewater treatment plant. The plans also include the construction of a drinking water pipe ensuring the supply of network drinking water to the planned wastewater treatment plant. PART 2: Development of the sewage network in the city (Not affected by the pilot plant) This part of the work can be implemented independently, technically separated from Part 1. Which includes, on the one hand, the expansion of the sewage network of Örkényi Street and its surroundings (“Design of a new sewage treatment plant and related facilities in Dabas, Design of sewage network development related to the new sewage treatment plant in Dabas, Design of sewage network development of Örkényi Street and its surroundings - implementation plan, Work number: 2024/T90” - folder named “Örkényi Street sewage network”).Gravity and pressure pipeline sections are being built on Örkényi Road and Szőlő, Akácos, Rabárerdő, Venyige, Fenyves Streets, with lifting shafts and related facilities.
