Understanding gravity systems
- Before we begin learning how to design gravity pipe networks in Civil 3D, let's first understand the nature of pipe networks themselves. Pipe network design in Civil 3D is divided into two types: gravity and pressure. Gravity pipe networks are, of course, used for gravity systems such as storm sewer and the gravity flow portions of sanitary sewers. In our example drawing here, we see some storm sewer inlets and walls and man holes. And the intentions of these systems is to collect and convey rainwater from where it's falling to a safe place where it can be treated and released safely back into the environment. For a gravity pipe system to function properly, it has to be designed with a few important requirements in mind. The pipes have to have enough slope for water to flow through them, because after all, we're relying on gravity for water to flow. The pipes have to be large enough to pass the flow that they're expected to convey. We actually do calculations to figure this out. How…
