Wastewater Treatment Plant Construction Work - Execution Of Construction Works Consisting In The Expansion And Modernization Of The Sewage Treatment Plant In Działdowo As Part Of The Project Entitled: Implementation Of Obligations Arising From Directive 91/271/Eec In The Działdowo - Expansion And Modernization Of Sewage Plant In Działdowo. The Subject Of The Contract Is The Execution Of Construction Works Involving The Expansion And Modernization Of The Sewage Treatment Plant In Działdowo As Part Of The Project Entitled: Implementation Of Obligations Arising From Directive 91/271/Eec In The Agglomeration Działdowo-Expansion And Modernization Of The Sewage Treatment Plant In Działdowo As Part Of Fenx.01.03 Water And Sewage Management Of Fenx 01 Priority. Energy And Environment From The Cohesion Fund Of The European Funds For Infrastructure, Climate, Environment 2021-2027 (Hereinafter Project). The Place Of Implementation Of The Subject Of The Contract Is The Area Of ​​Przedsiębiorstwo Gospodarki Komunalnej I Mieszkaniowa Sp.Z O.O. With Its Registered Office In Działdowo (13-200), At Ul. Gen. J. Haller 32. The Investment Is The Extension And Modernization Of The Existing Sewage Treatment Plant In Działdowo. The Investment Provides For The Reconstruction And Extension Of The Existing Sewage Treatment Plant By Building New Facilities And The Reconstruction Of Existing Facilities. The Part Of Mechanical Sewage Treatment And Process Automation Will Be Subject To Modernization In Terms Of Technology. After Modernization, The Sewage From The Sewage Pumping Station Will Be Pressed Into The New Expansion Chamber. A Valve Chamber Will Be Built In Front Of The New Expansion Chamber, Enabling Redirection Of The Sewage Stream To The Existing Expansion Chamber No. 1. The Existing Sandstone Will Be Left As Emergency, In The Event Of Service Works Or Failures Of The New Sandstone. From The New Expansion Chamber, Sewage Will Go To A New Sandbox.
