Sewage Treatment Tenders

Details: The subject of the planning is the Luckenwalde sewage treatment plant, in particular the biological/chemical treatment stage. Planning solutions must be found for the following key problems: The biological stage is currently strictly structured as two-lane systems, with no mutual redundancy. For example, aeration tank (bb) 1 cannot be operated together with secondary clarifier (nkb) 2 or nkb 1 and nkb 2. The sludge from both bb lines is currently kept separate and there is no mixing. This severely limits possible operating conditions. In particular, if one tank fails, the entire line fails. The sludge properties can develop very differently in the two lines, which can lead to operational problems. The tanks are not hydraulically separated, which means that the water level upstream in the bb and in the inlet distributor structure is influenced by the water level in the nkb. The return sludge pumps are also not hydraulically separated, so that the pump output directly influences the water level in the Nkb. The basins and structures have little freeboard, there are practically no hydraulic reserves. The economical construction method meant that with the existing building fabric, a hydraulic separation of the basins and structures is not possible while maintaining the design inflow. Bb and Nkb are each connected by submerged outgoing and incoming short pipes. Therefore, it is currently not possible to add P-precipitant to the Bb outlet (preferred recommended dosing point - see Dwa M 206). Machinery and equipment are over 25 years old, the building fabric is in need of renovation. In particular, the inlet distribution shaft on the west side of the building is in dire need of renovation on the concrete side and is to be replaced. From a process engineering point of view, cross-redundancy of the tanks and merging of the flows after each tank (mixing and re-dividing) would be recommended in order to make the operation safer and more stable.

Details: The Subject of the Public Contract is the Construction of the "Sewage Drainage of the Municipality of Samotišky" Related to the Project of the Contracting Authority with the Title "Sewage Drainage of the Municipality of Samotišky", Project Registration Number 1240700027 Within the Framework of the Subsidy Title Financed from the National Environment Program. In the Municipality of Samotišky, it is proposed to build a new sewage gravity sewer system terminated by the Samotišky pumping station, which will transport wastewater by pressure to the sewer network of the City of Olomouc - to the collector "k" leading in the extravilán of the local part of Droždín, which drains wastewater towards the local part of Olomouc Chválkovic. The sewage wastewater of the Municipality of Samotišky will be treated at the Olomouc sewage treatment plant. Technical and Technological Description of the Individual Parts of the Subject of the Public Contract, Including the Project Documentation and the Bill of Quantities, Which Forms an Annex to the Tender Documentation. The Contractor undertakes to carry out the work in accordance with the Tender Conditions and the Project Documentation. All Requirements for the Contractor arising from the Project Documentation are binding on the Contractor and must be included in the Supplier's Offer. Completion of the Work means the complete, functional and flawless execution of all construction and assembly works and structures, including the supply of necessary materials and equipment necessary for the proper completion of the work, as well as the performance of all activities related to the supply of construction works and structures, the performance of which is necessary for the proper completion of the work, including the coordination and completion activities of the entire construction. The Work Will Be Implemented In Accordance With The Applicable Laws Of The Czech Republic And The Czech Republic And According To Generally Binding And Recommended Regulations And Methodologies. The Client Emphasizes That The Contractor Of The Work Must Comply With All Technical And Technological Procedures Within The Implementation Of Individual Works Under The Order. The Basis For The Preparation Of The Offer Is The Project Documentation For The Implementation Of The Construction Of The "Sewage Treatment Of The Municipality Of Samotišky" Prepared By The Contractor - The Association Of Companies Aqp+vodis, Formed By The Company Aqua Procon Sro, Registered Office Palackého 12, 612 00 Brno, Company No.: 46964371 And The Company Vodis Olomouc Sro, Registered Office Tovární 1059/41, 772 11 Olomouc, Company No.: 25835815, In 05/2023 And Further See Project Documentation (hereinafter referred to as the "Project Documentation"). All features, procedures, requirements and specifications are stated in the draft contract for the work, which is annex no. 3 to this tender documentation and in the project documentation, which, together with the statement of quantities, is annex no. 4 to this tender documentation. The contracting authority expressly mentions the need to carry out the work in accordance with the document Methodology for the DNSH principle. This methodology has application priority over the project documentation, i.e. in the event of a conflict regarding the method of carrying out the work, the procedure according to the document Methodology for the DNSH principle will be preferred, or the work will be carried out in such a way that this methodology for the DNSH principle is observed. The contractor also undertakes to properly document compliance with this methodology as required by the subsidy provider. Both the Methodology for the DNSH Principle and the Requirements for Its Reporting Are Part of the Project Documentation, or Are Available in Their Current Form on the Website of the Subsidy Provider at Https://www.mzp.cz/cz/podminky_cerpani_eu_fondu Technical Supervision for This Contract May Not Be Performed by the Supplier or a Person Connected to It. If the Terms of Reference, Technical Specifications, Project Documentation or Statement of Quantities Refers to Certain Suppliers, Products or Patents for Inventions, Utility Models, Industrial Designs, Trademarks or Designations of Origin, Pursuant to the Provisions of Section 89, Paragraph 6 of Act No. 134/2016 Coll., On the Award of Public Contracts, Considers Such a Reference to be a Specification of Technical Conditions Which Would Not Be Sufficiently Precise and Comprehensible Without Its Use. The Contracting Authority Explicitly States and Admits the Possibility of Offering Another Equivalent Solution for Each Such Reference.
