Tenders Are Invited For Construction Of A Water Supply Network And Sanitary Sewage System With Connections In The Town Of Chojno

4. The Scope Of Construction Works Carried Out As Part Of This Investment Includes: A) Water Supply Network With Connections The Designed Water Supply Network Should Be Incorporated Into The Existing Water Supply Network Made Of Pvc 110 Pipes By Building A Water Supply Node. Along The Route Of The Designed Water Supply Network, Eight Above-Ground Fire Hydrants Dn 80 Were Planned To Be Built. In Addition, Forty Water Supply Connections Were Planned Along The Route Of The Water Supply Network. Water Supply Connections Should Be Made Of Pe 40 Sdr 17 Pn 10 Pipes. The Connections Should Be Incorporated Into The Designed Network By Installing Self-Drilling Clamps Type Nwz/Pe 100/40 With Cut-Off Valves Dn 32. Water Supply Connections Should Be Terminated With A Pe 40 System Plug On Individual Building Plots. Along The Route Of The Designed Network, A Passage Under The Municipal Road Should Be Made Using The Trenchless Method, Using Jacking In A Protective Steel Pipe Dn 216/10 L = 14.0 M. The Water Supply Should Be Laid At A Depth Of At Least 1.8 M Below The Ground Surface. A Water Supply Network Was Designed Using Pvc 110, Pn 10 Pipes Connected With Gaskets. The Water Supply Network Should Be Marked In The Ground With A Location Tape Placed 0.2 M Above The Water Supply Cable. The Total Length Of The Designed Water Supply Network Will Be - 1640.0 M, Of Which: - Pe 40 Pn 10 Sdr 11 -238.0 M, - Pvc 110 Pn 10 -1402.0 M, - Above-Ground Hydrant – Set 8,- Assembly Nodes - Set 3,- Self-Drilling Clamps Dn 110/40 - Set 40,- Jacking With A Steel Pipe 216/10 L = 35 M / 2 Sets.B) Sanitary Sewage Network With Connections: The Construction Of A Gravity-Pressure Sanitary Sewage System With Connections Was Also Designed. The Designed Network Should Be Connected To The Existing Pvc 200 Collector By Building A Dn 1.200 Inspection Well And Creating A Base. At The Place Of Installation Of The Well, It Is Planned To Dismantle The 5X5m Asphalt And Rebuild It Again. The Planned Construction Of The Sanitary Sewage Network Should Be Made Of Pvc Pipes Dn 200 And Pvc 160 Sn 8 Lite Pipes And Pe 90 Sdr 17 Pn 10. Along The Route Of The Sanitary Sewage Network Under The Construction Plots, It Is Planned To Install The Sanitary Sewage System In A Pe 355 Pn 10 Sdr 17 Casing Pipe L = 83.0 M. Inspection Wells Dn 1,200 With A Wall Thickness Of At Least 135 Mm With Profiled Bases Were Designed By The Well Manufacturer, And Pvc Dn 400 Wells For Sanitary Sewage Connections. A System Expansion Well Made Of Pe Dn 1000 Was Designed Along The Sanitary Sewage Route. A Sewage Pumping Station In A Polymer Concrete Chamber Dn Internal Was Also Designed. 2000. For The Installation Of A Sewage Pumping Station, It Was Planned To Build A System Panel Fence On The Foundation And Harden It With 6.0 Cm Thick Concrete Cubes Secured With An 8/30/100 Curb. Sewer Lines: For Sewage Collectors, Use Sewage Lines Made Of Pvc Dn160, Pvc 200 Sn8 With A Solid Wall And Pipes Made Of Pe 90 Sdr 17 Pn 10. Wires Should Be U
