Tenders Are Invited For Design And Realization Optimization Of The Wwtp Sliedrecht in Netherlands The

Work Detail

Assignment Description To Make The Wwtp Stry -Proof To At Least 2040 Are Renovation, Adjustments And Extensions To The Wwtp. The Waterline Of The Current Wwtp Is At The End Of Its Technical Lifespan. The Civil Constructions Require Inspection And Repair. Mechanical Components Are Due For Replacement. With The Work For The Renovation, Wsrl Also Wants To Increase The Capacity Of The Wwtp So That The Wwtp Can Incorporate The Forotized Increase In The Biological Load. The Current Capacity Of The Wwtp Is 48,000 I.E. (À 150 Grams Of Tzv) And Hydraulically 1,650 M3/H. The Wwtp Must Be Extended To A Biological Capacity Of 73,000 I.E., What The Forotized Load Is In 2033. The Planned Renovation And Expansion Is Based On The Placement Of A Fine Sieve, Recirculation In The Aeration Tanks And The Addition Of Additional Astr For The Biological Capacity Of The Wwzi. Wsrl Wants To Jointly Develop The Preliminary Draft (Vo) And The Final Design (Do) With A Contractor In The Construction Team (Phase 1). The Assignment States That The Contractor Will Be Granted The Implementation Design (Uo) And The Realization (Phase 2) After Completion Of The Do, On The Condition That Wsrl And The Contractor Will Agree On The Contract Sum For Phase 2 Phase 1 - Draft Wsrl Concludes An Agreement With One Contractor For The Elaboration Of The Design. It Is About: Elaboration Of The Design Principles Into A Preliminary Draft (Vo); Further Elaboration Towards A Definitive Design (Do). This Phase Is Performed Under The Conditions Of The Awvodi. Important Design Principles Are: Fine Sieve Application: It Was Decided To Place A Fine Sieve Based On An Earlier Pilot. In Secondary Education, The Choice Must Be Made Whether And How Opportunities For Raw Material Extraction (Including Cellulose) Must Be Taken Directly Or Later. Recirculation In Aeration Tanks: Research And Design Of A Solution To Increase Capacity With Recirculation Pumps And Extra Aeration Plates, And Decision -Making On The Future Role Of The Existing Rotating Bridge. Renovation Of The Wwtp: The Waterline And Parts Of The Sliblin Must Be Inspected, After Which The Need Must Be Determined Of A Renovation/Revision Or Replacement. Phase 2 - Engineering & Realization After Completion Of The Do, The Contractor Can Also Carry Out The Engineering And The Realization In The Event Of An Agreement On Price And Conditions. This Phase Is Performed Under The Conditions Of The Uav-Gc 2025. Result And Objectives The End Result Of The Project Is A Renovated An Adapted Wwtp Sliedrecht That Functions Reliably, Efficiently And Future-Proof.
