Design of Wastewater transmission pipelines<\/strong><\/h2>\n
Wastewater transmission pipelines are a particular type of infrastructure with critical consideration in the design stage such as safety issues due to the fact that wastewater transmission pipelines generally convey significant sewerage flow from the collection network to a wastewater treatment plant. Therefore, the design procedure not only should meet the minimum criteria for the correct sizing of components to complement the baseline parameters and the basis for developing custom designs but also should interface design between components such as pipes, manholes and access structures, whole system reliability in any unforeseen circumstances.<\/p>\n

Design of wastewater transmission pipelines comprises main items as follows:\u00a0\u27a3\u00a0Analysis of Design flow<\/p>\n
\n
Determine the design period<\/li>\n
Flow from the upstream infrastructures such as collection networks, pumping stations, etc.<\/li>\n
Regional Analysis to specify land-use and regional extensions<\/li>\n
Per capita flow analysis for residential users and commercial or other nonresidential effluents<\/li>\n
Infiltration and inflow analysis and storm runoff estimation<\/li>\n<\/ul>\n
\u27a3\u00a0Define design criteria;<\/p>\n
\n
Pipe and canal material<\/li>\n
Manhole material<\/li>\n
Min. conduit size<\/li>\n
Conduit velocity range<\/li>\n
Conduit depth of flow range<\/li>\n
Conduit slope range<\/li>\n
Conduit construction depth range<\/li>\n
Modeling and design method<\/li>\n<\/ul>\n
\u27a3\u00a0Hydraulic Design<\/p>\n
\n
Preparing the layout of alternatives of wastewater transmission pipeline with technical-economic comparison<\/li>\n
Creating the model by allocating topographical and flow data<\/li>\n
Designing the transmission line to specify the conduit size and invert elevation and considering design criteria and constraints.<\/li>\n<\/ul>\n
\u27a3\u00a0Design of other components;<\/p>\n
\n
Manhole<\/li>\n
Drop manholes<\/li>\n
Inverted siphon<\/li>\n
Overflow structures<\/li>\n
Weir structures<\/li>\n<\/ul>\n
\u27a3\u00a0Construction Plan and drawings<\/p>\n
\n
Establishing layout and drawings for the construction stage and preparing BOQ (bill of quantity) report is an important part of the design procedure to estimate cost of construction and manage the tenders. POD delivers this service by fully-automated software to create construction drawings in plan and profile sheets both facilitating implementation of detailed plan of wastewater transmission pipeline. POD network plan and profile maker provide some exclusive features as in the following:\n
\n
\u00a0<\/li>\n
Precise data illustration of pipe and manhole<\/li>\n
Best direction and place to avoid interference of data<\/li>\n
Add or remove any data from the collection<\/li>\n
Customizing the drawing method for example in a table or by a leader line<\/li>\n
Changing the font type and size easily<\/li>\n
Select and filter the elements by specific data field<\/li>\n
Open, save, edit and copy the drawing in CAD-based platform<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n
