Tenders Are Invited For Modernization Of The Municipal Sewage Treatment Plant In Jeżewo

The Subject Of The Order Is The Modernization Of The Municipal Sewage Treatment Plant In Jeżewo In Order To Ensure Good Environmental Condition Through Proper Treatment Of Sewage That Will Be Supplied Now And In The Future. The Municipal Sewage Treatment Plant In Jeżewo Is Located In Jeżewo, Ul. Łąkowa 2, Plot No. 58/11, Jeżewo District, Jeżewo Commune, Świecie Poviat, Province. Kuyavian-Pomeranian Voivodeship. The Modernization Of The Sewage Treatment Plant, Which Is The Subject Of The Investment, Is Located On The Above Plot, Within The Boundaries Of The Currently Existing Fence, With An Area Of ​​Approximately 0.8969 Ha. The Sewage Treatment Plant Was Built On Virtually Virgin Land And Was Put Into Operation In 2003. The Following Facilities Are Currently Located On The Premises Of The Sewage Treatment Plant In Jeżewo: - Sewage Pumping Station - A Technological Facility Including Two Intake Wells And A Gate Valve Chamber, - Grate Building, - Vertical Sand Trap, - The First Reactor - A Facility Including The Following Technological Components:• Kdp Dephosphatation Chamber• Kdn Denitrification Chamber• Kn Nitrification Chamber• Ow Secondary Settling Tank• Krw ​​Internal Recirculation Chamber• Krz External Recirculation Chamber• Ktso Oxygen Stabilization Chamber - Blower Station, - Sludge Dewatering Station - Both Stations Located In A Common Building, - Technical Service Building, - Dewatered Sludge Storage, - Purified Sewage Measuring Chamber, - Equipment Shelter, - Feed Sewage Collection Station, - Feed Sewage Tank, - Sewage Retention Tank, - Retained Sewage Pumping Station, - Gas Tank, - Pole Transformer Station, - Telecommunications Mast. The Scope Of Modernization Of The Municipal Sewage Treatment Plant In Jeżewo Is To Include The Construction Of A Second Reactor With A Technological And Construction Form Analogous To The Existing First Reactor, Taking Into Account The Necessary Activities To Ensure The Supply Of Compressed Air To The New Reactor And Its Connection With Existing Facilities, Networks And Automation System. In The Designed System, It Will Be Possible To Operate Both Reactors Simultaneously Or Only One Of Them. The Following Activities Are Planned As Part Of The Investment:• First Reactor - Reconstruction Of The Installation In The Existing Facility. Modernization Of The Existing Reactor Will Include Reconstruction Of The Compressed Air Installation In Order To Adapt It To The Planned System. Aeration Of Two Reactors From One Common Source Of Compressed Air (I.E. Blower Station). The Planned System Will Have Two Reactors, And Each Of Them Will Have Two Separately Aerated Chambers (The Kn Chamber And The Ktso Chamber), So There Will Be A Total Of (At Least) Four Chambers With Individually Different Demands For Compressed Air Supplied From One Common Source. • The Second Reactor - Construction Of A New Facility Including The Following Technological Components: - Kdp Dephosphatation Chamber - Kdn Denitrification Chamber - Kn Nitr
