It Is Planned To Build A Gravity Sanitary Sewage System, A Sanitary Sewage Pumping Station, A Home Pumping Station And Pressure Sections. Properties Located In The Area In Question Will Have Gravity Connections To The Property Boundaries. 2. It Is Planned To Build A Sanitary Sewage Network With The Following Parameters: • Gravity Channels Made Of Class S Pvc Pipes (8.0 Kn/M2) Ø200mm – 2467.9 M • Pressure Channel Made Of Pe Hd Sdr 17 Pipes Ø90mm – 174.4 M • Pressure Channel Made Of Pe Hd Sdr 17 Pipes Ø110mm – 664.0 M • Pressure Channel Made Of Pe Hd Sdr 17 Pipes Ø125mm – 1123.6 M • Connections: - Gravity From S Class Pvc Pipes (8.0 Kn/M2) Ø160mm – 502.80 M - Gravity From S Class Pvc Pipes (8.0 Kn/M2) Ø200mm – 46.4 M - Pressure From Pe Hd Sdr 11 Pipes Ø63mm – 83.0 M • Planned Sanitary Sewage Pumping Station Ø2000mm – 2 Pcs. • Rebuilt Sanitary Sewage Pumping Station Ø2000mm – 1 Pc. • Rebuilt Settling Well Made Of Polymer Concrete Dn1500 – 1 Pc. • Reinforced Concrete Wells Dn1000mm – 29 Pcs. • Plastic Manholes Without Manholes Ø400mm – 63 Pcs. • Plastic Expansion Well Ø1000mm – 1 Pc. • Tee Well Dn1000 – 1 Pc. • Deaeration And Aeration Well Dn1200 – 3 Pcs. • Flushing Well Dn1200 – 3 Pcs. 3. The Construction Of A Sanitary Sewage Network Was Designed: • Gravity From Pvc-U Pipes Ø200 Sn 8 Sdr 34, • Pressure From Pe Hd Pipes Ø90-125 Butt Welded. In The Case Of Excavation Work, Pipes And Fittings In The Pe-Hd Sdr 17 Technology, Class 100, Pn 10 Can Be Used. • The Sanitary Sewage Network Is Reinforced With The Following Devices: • Sewage Pumping Station • Intermediate Inspection And Connection Wells Located On The Gravity Network, • Expansion Well Located At The End Of The Pressure Pipeline, Before Turning On The Gravity Part Of The Sanitary Sewage System, • Sanitary Sewage Connections Directed Towards Existing Internal Installations Residential Buildings And Undeveloped Building Plots Located In The Area In Question. Attention Is Drawn To Possible Discrepancies In The Location Of The Utilities Included In The Project And The Actual Situation, As Well As To The Existence Of Utilities In The Field That Have Not Been Surveyed. Cross Passages In The Road Right-Of-Way Of District Road No. 1909C (Under The Road) Should Be Made Without Trenches In A Protective Pipe. Wells Concrete Sewage Wells Dn 1000 - The Wells Should Be Made Of Concrete Rings In Diameters Dn1000 Connected With Rubber Gaskets With A Base In A Prefabricated Bottom, A Cover Plate With A Relief Ring And A Cast Iron Manhole. Inspection Wells Should Be Equipped With Cast Iron Manhole Steps With Anti-Corrosion Protection. Cover Elements (Ceiling Slabs) With Manholes Equipped With A Ø625mm Opening Adapted For Sewer Manholes. Manhole Class - Cast Iron Manhole D400kn. Wells Should Be Protected Against Damage. Tight Passages For Pvc Pipes Wi
