Description

Auto-translated from German

The wastewater treatment facilities of the city of Querfurt currently include the operation of mechanical pre-treatment at the historical site of the Querfurt wastewater treatment plant and a 20-year-old wastewater transfer to the Karstdorf wastewater treatment plant. Biological treatment and further sludge treatment take place there. The transfer to the Karsdorf wastewater treatment plant is severely damaged and the energy expenditure for transport is disproportionately high. Therefore, planning for the optimization of wastewater treatment is to be developed. Previous preliminary investigations have shown that replacing the transfer and building a biological treatment stage are the most energy-efficient options. In the course of a feasibility study in service phase 2, a renovation of the transfer is to be considered as an additional option. The aim of the planning is the energy optimization of the existing wastewater treatment and the subsequent transfer to Karsdorf, taking into account all relevant framework conditions. For this purpose, planning services according to HOAI are required in the areas of buildings, civil structures, technical equipment, EMSR, and structural planning. If necessary, various expansion stages must also be considered. The various measures and the exact objectives can be found in the tender documents (D1_Leistungsbeschreibung). Based on the EU Municipal Wastewater Directive, the wastewater treatment plant to be planned must be designed in such a way that: - the share of self-generated electricity is at least 70%, - the specific energy consumption of the plant is max. 23 kWh/EW, - the plant is capable of reliably meeting the specified monitoring values in the effluent. The planning services to be provided (breakdown of service areas and service phases) are also summarized in detail in the service description (D1). The following dates are planned for the execution of the tendered planning services: Planning start: 09/2026 LPH 2: Preliminary planning reading version 12/2026 LPH 2: Completion and handover of the complete preliminary planning 01/2027
