6.7. PROFOS pressure pipeline-discharging pipeThe definition of the diameters of the pressure pipeline-discharging pipe is based on:● Flow rate shower;● Velocities at which the casts are minimal;● The allowed minimal velocities for movement of waste waters;● The danger of waste waters rotting when the stay is bigger in the pipelines;● The adnger of clogging;● The pipeline material must be in accordance with the pressure requirements, quality characteristics of waste waters and the soil;● The pipelines must be resistant to external and internal loads and to be watertight.6.8. Project documentation preparationPipelife offers the designers preparation of a project of a sewage pump station in accordance with the standards and the requirementswhich are applicable to the final product of your investment projects.The project, prepared by our engineers includes:1 Selection of the appropriate pump aggregate-one or two in accordance with the specific situation2 Pump’s type with technical parameters, work diagrams, drawings of the details3 Manholes selection, equipment with the selected pump aggregate, assembly and pipeline connections4 Situating on the desired by the investor spot5 Detailed drawings and profiles of the specific design situation6 Technical note with calculations7 Assembly and exploitation conditions8 Price of the selected productIn order to prepared the above mentioned project documentation it is necessary to submit the following data (see Table 7):Necessary parameters Designation Data CommentWaste water capacity (l/s or m 3 /h)QFor household waste waters –the maximal water quantity.
