Another component to be designed in the building (house) drainage system is the storm drain system<\/strong>, the one responsible for capturing and conveying the rainwater from the building\u2019s areas (roof, parking, etc.) to an approved point of disposal.<\/p>\n

With our software DESAG\u00dcES (DRAINS), besides what has been seen in relation to the design of sanitary drainage system components in buildings, it is also possible to perform the design of Leaders and Storm Building (house) Drains<\/strong> as we shall see below.<\/p>\n

The storm drainage system design in buildings with DESAG\u00dcES is based on establishing, in the software\u2019s Pipes\u2019 Diameters Manager of the program<\/strong>, the maximum permissible projected drainage area that can be conveyed by Leaders as well as storm building drains. <\/strong>In this tutorial,<\/a> we have detailed how to introduce this data in the software, specifically relative to the values \u200b\u200byou need to specify to adapt the design to your country\u2019s standards code regulations<\/strong>.<\/p>\n

Thus, having made the geometric design of the storm drainage system in your preferred drawing software, it is possible to import storm drain pipes, inlets, and inspection chambers<\/strong> into the software, therefore having, in a few seconds, the storm system\u2019s mathematical model ready to be designed, through the definition of the diameter for leaders<\/strong> and longitudinal slopes and diameters for storm building drains<\/strong>.<\/p>\n

We\u00b4ll continue using the edification\u2019s example used in the sanitary drainage design tutorials to develop the actual article, so let\u00b4s see the steps involved in the design of the storm drainage system in buildings using DESAG\u00dcES:<\/p>\n

1. What you need to have: The storm building drains layout and the tributary areas to Leaders (roof drains) and inlets.<\/h2>\n

As we talked previously, the main necessary input is that you have, at least, a schematic diagram of the storm drainage system<\/strong>. This is the leaders\u2019 location on the building\u2019s roof, their discharge points (inspection chambers), their tributary areas, the storm building drains layout, its inlets (if any), inspection chambers, and location of the system\u2019s discharge point.<\/p>\n

Of course, in order to exploit the software\u2019s features related to the automatic determination of lengths, and create an annotated plan and isometrics drawings<\/strong>, the ideal situation is that, instead of schematics, you have the proposed layout drawn to scale and in a drawing file in DXF format which you can import into the program.<\/strong><\/p>\n

In our edification\u2019s example we\u2019ll use the last option<\/strong>. We have drawn on AUTOCAD\u00ae and on top of the building\u2019s architectural plan, the storm drainage system using lines, polylines, and single line text as specified in this tutorial<\/a>. The plan layout is presented in the figure below (remember that the building is symmetrical):<\/p>\n

As seen on the above image, we’ve added some notes so that you know what the involved levels are (roof level: 15 m elevation and parking at ground level: 0.00 m) as well as tributaries areas, in square meters (m2),<\/strong> which will be drained to Leaders and Inlet chambers.<\/p>\n

Specifically, in DESAG\u00dcES, it will be necessary to create:<\/p>\n
