Work Detail

The Subject Of The Order Is The Task Entitled: Construction Of A Sanitary Sewage System And A Vacuum Station In Kalety Miotek, Zielona, ​​Mokrus, Truszczyca. Stage Iii - Kalety Mokrus With Connections., In The Scope Of: 1.Vacuum Pipelines: Pe Pipelines Dz 160 Mm, L = 399 [M] Pe Pipelines Dz 125 Mm, L = 306 [M] Pe Pipelines Dz 110 Mm, L = 1176 [M] Pe Pipelines Dz 90 Mm, L = 1251 [M]2.Gravity Pipelines: Pvc Pipelines Dz 160 Mm, L = 1540 [M]3.Cable Monitoring Of Vacuum Sewage: 1 Set. The Offer Is Required To Include The Connection Of Buildings To The Sanitary Sewage Network In Accordance With The Technical Documentation And Bills Of Quantities. Vacuum Wells: The Vacuum Well Is To Ensure Clear Physical Separation/Separation Of The Sewage Chamber From The Valve Chamber. The Vacuum Valve Is To Be Accessible From Ground Level Without The Need To Enter The Valve Chamber Of The Well. Both Chambers Of The Vacuum Well Must Be Separated Using A Special Vacuum-Tight Closure. Valve Chambers Must Be Separated From Sewage Chambers. The Valve Chamber Must Have A Service Tee With A Plug At The Vacuum Inlet Enabling The Valve To Be Isolated For Servicing Or During Construction. This Tee Must Also Enable The Connection Of A Special Suction Pipe Enabling The Removal Of Obstacles From The Sewage Chamber. The Inflow Of Sewage From The Building Is To Be Carried Out Using A Standard Gravity Pipeline. The Valves Should Be Activated By A Pneumatic Device Without The Need To Use Electricity. Mechanical Or Float Actuation Is Not Permitted Due To The Possibility Of Blocking. The Valve Body Should Be Made Of Abs Plastic. Diaphragms Should Be Made Of Epdm Material Resistant To Sewage. The Valves Should Be Watertight, Compact, Take Up Little Space And Be Light In Weight So That They Can Be Easily Serviced. The Vacuum Valve And Controller Must Be Easily Accessible. The Negative Pressure Well Is Intended To Prevent Groundwater Infiltration. For This Reason, It Is Preferred To Use Complete And Tight Systems Made Of Pe. Valve Chambers And Sewage Chambers Of Manholes Are Also To Be Made Of Pe. The Connection Of The Gravity Pipeline Discharging Sewage From The Building Is To Have A Diameter Of Dn 160. A Section Of The Pipeline Discharging Sewage From The Building With A Diameter Of Dn 160 Serves As An Emergency Additional Capacity. The Vacuum Well Is To Have A Connection For Removing Sewage In Emergency Cases Using A Simple Vacuum-Tight Ball Valve. Controller: The Controller Must Be Able To Be Mounted Using A Quick Connector, In A Vertical Position To The Valve Body Inside A Dry And Clean Valve Chamber Of The Well. The Controller Is To Be Made Of Polyamide Reinforced With Glass Fiber. The Controller Cannot Require Additional External Power Supply, E.G. Electricity. The Design Of The Controller Is To Ensure That The Vacuum Valve Is Opened When The Sewage Level In The Tank Reaches The Set Level And Turned Off At A Minimum Negative Pressure Of -22 Kpa To Eliminate The Possibility Of Par
