Stormwater Network Design<\/strong><\/h2>\n
Stormwater drainage design is an integral component of both site and overall stormwater management design. Stormwater collection systems must be designed to provide adequate surface drainage while at the same time meeting other stormwater management goals such as water quality and groundwater recharge, etc.<\/p>\n
Stormwater drainage systems can be categorized into minor (inlets, street and roadway gutters, small channels, and small underground pipes) and major systems (trunk lines that receive the water from the minor system). Three considerations largely shape the design of these systems: flooding, public safety and water quality.
To achieve this, POD has developed an exclusive software called \u201cNetU\u201d with robust engine design to provide the designers along with special features to deliver an optimized plan. To learn more about NetU\u00a0click here<\/a>.<\/p>\n

Design of stormwater network comprises main items as follows:<\/strong><\/p>\n
\u27a3\u00a0Analysis of Design flow for each conduit<\/h4>\n
\n
Determine the design period<\/li>\n
Topography analysis 1- to determine runoff pattern; high points, ridges, valleys, streams, 2- Check potential drainage outlets; On-site (structural control, receiving water), Off-site (highway, storm drain, receiving water, regional control), Natural drainage system (swales), Existing drainage system (drain pipe).<\/li>\n
Regional Analysis to specify land-use, city or rural service boundary and extensions<\/li>\n
Run-off pattern and flow analysis<\/li>\n<\/ul>\n
\u27a3\u00a0Assessment of existing network<\/h4>\n
\n
Preparing the layout of existing stormwater network<\/li>\n
Evaluation of construction data as conduit size, slope, upstream and downstream invert elevation.<\/li>\n
Modeling the existing network to determine the capacity with the latest flow analysis during the design period<\/li>\n
Attune the qualified existing stormwater network with new proposed network; the connection and any modification if needed.<\/li>\n<\/ul>\n

Preparing the layout of stormwater network both minor and major in the area; drawing a tree-line network within a city or a vast area is a time-consuming operation. POD has developed an outstanding feature to draw the network in an automatic process of an aerial image of the plan area<\/li>\n
Creating the network model by allocating topographical and flow data for each element<\/li>\n
Designing the network to specify the conduit size and invert elevation and considering design criteria and constraints.<\/li>\n<\/ul>\n

\u27a3\u00a0Construction Plan and drawings<\/h4>\n
\n
Drawings are so important how to transfer the design data of stormwater network in the construction process in the simplest but precise way. The construction drawing by this concept will guarantee the quality of construction, and also leads to decrease in the construction period. POD delivers this service by fully-automated software to create construction drawings in plan and profile sheets both facilitating implementation of detailed plan of stormwater network. POD network plan and profile maker provide some exclusive features as in the following:\n
\n
Precise data illustration of each element<\/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
