I dont see anywhere in the linked blog post that talks about how that drain was constructed. However, walkout drains should be designing for the maximum precipitation in a single storm, say in a 15 minute period. In Herriman where I live we get microbursts 2-3x per year where even the drains in the curb will be overwhelmed. This has happened several times in the 20 years I have lived here.
Hello David, This drain style is proven and works well for many people in your area. However, it may not be a good fit for you in your particular application. We missed putting that link. Sorry about that. The drains we build are designed for the maximum rain fall in a 15 or so minute rain fall. In the video we did this, and then added about 3x more water just to see if it would still be ok, and it was! While we have built these drains like this for several years and never had a problem, in Herriman and Lehi and other areas around Salt Lake, this is partly because we make sure water does not drain toward the walkout. So the only water we need to drain is the actual rain fall. In a heavy rain, there just simply is not that much water that falls into the walkout based on its relatively small square footage. This is why they do not flood over. If you are concerned about the drain having capacity problems, we can definitely increase its size and volume capacity. We could also install an electric pump that pushes the water up and out to a location of your choosing, maybe the street or other location so it can be added to the storm water the city manages. There are plenty of options for your choosing, and while this drain works well for many people, it may not be the right fit for you. Thanks for watching and I hope you enjoy our other videos. Have a nice day!
We are updating the link we missed in the video. I wanted to let you know this is the link to how the drain is built: ruclips.net/video/6RemRBorjDs/видео.html
