Explore the detailed procedure of creating and implementing a new drainage network, starting with minor modifications to a sedimentation basin and ending with a fully functional storm drain system. The article covers everything from initiating pipe network creation tools to inspecting the final 3D model of the newly built drainage network.
Key Insights
- The creation of a drainage network begins with minor edits to the sedimentation basin. This includes adding infill and updating the surfaces.
- The drainage network is created using a pipe network creation tool, ensuring that there are no assigned alignments or labels. The network is constructed upslope, starting with the outfall headwall.
- The final step involves viewing the newly created drainage network in 3D to ensure all lots are connected to the main trunk and drain out to the outfall.

Now that we've moved this sedimentation basin down to a better location to drain all of our pads to it, we have to do a couple of little edits before that. I noticed that we're missing our infill from our sedimentation basin, so we've got to go ahead and go add that back.
We're going to go ahead and go to grading, creating creation tools. We're going to go ahead and make sure that we're in the dev main, dev main grade, and we're going to go ahead and go to this drop down for create infill. We're going to go ahead and pick inside of our feature line, and we're going to go ahead and hit ENTER, and then we're going to close out this window.
We're going to go ahead and go up to surfaces. We're going to update this dev combo. We're going to right click and select rebuild.
We're going to go to finish construction, right click and select rebuild, and from here now we're ready to start building this new drainage network. We're going to go ahead and start by drawing a pipe network. We're going to go ahead and go to pipe network creation tools.
We're going to create this pipe network by calling it dev branch strm like we did before. We're going to go ahead and go with a storm sewer. We're going to be targeting our finished construction surface, and we're not going to be assigning an alignment, a structured label, or a pipe label.

So I'm going to go ahead and click okay, and from here we're going to go ahead and go into the creation method for our new network. We're going to first change the direction we're going to be building this thing upslope. So then we're going to select our first structure from the bottom of our network, which is going to be our outfall headwall.
Then we're going to be selecting our pipe. We're going to go ahead and go with another concrete pipe of 12 inches. My headwall is the first headwall here, my 38 × 6 × 37.
From here I'm going to go ahead and do pipes and structures, and again confirming we are going upslope. Now I'm going to build my network by snapping into a location somewhere around here. Then I'm going to place a new structure.
I'm going to go back to my rectangular structure slab top rectangular frame, my 15 × 15. I'm going to go ahead and place that structure here, and then I'm going to place a new structure on my lot 6 site. I'm going to go ahead and hit escape.
Now I'm going to go ahead and build another branch of the network by doing structures and pipes. Starting at this structure here, navigating up to the locations of my pads, I'm going to place a structure at each point where a pad can tie into it. So I'm going to click here, I'm going to click here, I'm going to click here, here, and here.
Now I'm going to go ahead and escape out. Now I'm going to place my structures. I'm going to go ahead and go structures only.
I'm going to place a structure at this location, at this location, at this location, at this location, and at this location. Now I'm going to go ahead and toggle my change in slope. I'm going to go to downslope.
I'm going to go to pipes so that I'm controlling based on this structure. So I'm going downslope from here to this structure, escape. I'm going to go on a pipe from this structure to this structure and escape.
I'm going to go from this structure to this structure using a pipe and escape. I'm going to go on to pipe again from this structure to this structure and escape. And then on my last connection, pipe from this structure to this structure.
I'm going to go ahead and escape, close out this toolbar. I'm going to go ahead and select my pipe network by expanding out pipe networks, expanding out networks, selecting dev branch storm, right-clicking, selecting. And then I'm going to go ahead and go to object viewer and view my new pipe network.
I'm going to bring this window over, expand it out and rotate into three-dimensional view. And so from here, what we can see is that we have a new storm drain network that connects all of our lots to a main trunk and drains out to our outfall. So I'm going to go ahead and close this.
I'm going to escape out and then I'm going to save my drawing and I'll meet you in the next video.
