The Subject Of The Order Is The Construction Of A Sanitary Sewage Network With The Necessary Technical Infrastructure For The Town Of Werlas In The Solina Commune, Including The Catchment Areas Of The Pw1 And Pw2 Pumping Stations. The Scope Of The Planned Investment Includes The Construction Of, Among Others: - Construction Of Gravity Sewage Collectors Made Of Pvc Line Pipes On A Length Of 3,684.50 M (Preparation Of The Site For Construction, Earthworks, Assembly Works), - Construction Of Pressure Sewage Collectors Made Of Pe Line Pipes On Length 2,543.00 Meters (Preparation Of The Site For Construction, Earthworks, Assembly Works), - Construction Of Manholes Plastic Sewage Systems For Inspection From Ground Level, - Construction Of Concrete Inspection Chambers For Inspection From The Bottom Of The Chamber, - Construction Of Sewage Pumping Stations Pw1 And Pw2 With Equipment In Polymer Concrete Tanks, Along With Fencing And Hardening Of The Pumping Station Area And Construction Of Exits, - Construction Of A Power Supply Energy To The Pw1 And Pw2 Pumping Stations, - Construction Of Sewerage Passages Through Obstacles, Collisions, - Reconstruction Of Surfaces, Among Others: Roads, Sidewalks, Squares. Due To The Terrain, Two Network Sewage Pumping Stations Were Designed, Marked As Pw1 And Pw2. The Designed Pw2 Pumping Station Will Enable The Transport Of Sewage Supplied To It Through Gravity Channels To The Pw1 Pumping Station, Which In Turn Will Enable The Transport Of Sewage Transferred From The Pw2 Pumping Station And Flowing Through Gravity Channels To The Existing Sanitary Sewage Network In The Town Of Zawóz And Further To The Sewage Treatment Plant Also In Zawóz. A Gravity Sewage System Was Designed With Pvc Line Pipes And A Pressure Sewage System With Pe Line Pipes. Inspection Chambers Are Designed To Be Made Of Plastic, With No Manholes, For Inspection From Ground Level: - Pvc/Pp Ø 400 - Pp Ø 400 Base, Sn8, Pvc/Pp Ø 400 Rising Pipes, Corrugated, Double-Layer Sn8, Topped With A Ø 315 Telescope With A Cast Iron Cover, Class B125 , D400 (Incl Roads), Connection Of The Rising Pipe With The Telescope Using A Pp Collar Ø 400/315, Tight Connection With Gaskets. Concrete Inspection Chambers Will Be Used To Enable Inspection From The Bottom Of The Manhole. Covering Concrete Manholes With A Reinforced Concrete Slab Or A Reduction Reducer And A Reinforced Concrete Slab. A Cast Iron Manhole With A Load Class Adapted To The Type Of Terrain Will Be Installed In The Slab. Depending On The Area Where The Well Will Be Located, Heavy Type Manholes (Roads, Entrances, Parking Lots) And Manholes For Wells Located In Other Areas Are Designed. The Approximate Lengths Of The Designed Sewage Network Are As Follows: - Gravity Sewerage Approx. 3,684.50 M - Pressure Sewage Approx. 2,543.00 M. A Detailed Description Of The Subject Of The Order Is Included In Annex No. 3 To Swz - Design Documentation And Technical Specification For The Execution And Acceptance Of Constru
