Sizing the drainage network

- [Instructor] If we were to pop underground here…and just change some of this…so it's a 60 diameter.…I don't want a sump on it.…I'm going to change that to zero,…change it to zero,…and what else?…I could change this particular pipe…to a 24 inch.…

So we've made those two changes now.…We've changed this inlet to a zero foot sump,…and we've changed this from a 20 inch pipe…to a 24 inch pipe.…Now, whenever you make changes to your drainage network,…the best thing to do is to size the drainage network again.…So let's hit Size the Drainage Network…and see whether those changes that we made…to those parts of the network are any good or not.…

So we can change the rainfall.…We're going to leave it at one and 10…because that's what we have to measure against,…and we're going to make sure…that it's using our OC_NC table, which it is.…So then, just hit Enter to size the drainage network.…Again, we need to wait for a little…because InfraWorks needs to redraw the drainage network…with all of its components.…

So that does take a little bit of time.…
