We are building a new attached garage and working out some of the final items before breaking ground once the ground thaws.
We have discussed with the building inspector for our town when he stopped out to close out a permit on new windows about options for a floor drain in this area. He said we are fine as long as it drains to daylight. I am fine with that. We are not washing cars in the garage or anything with a lot of volume but mainly it will be snow melt.
The garage is 30x40, 3 car with 3 single 9' garage doors with in floor heat. We originally were thinking of centering two floor drains kind of like what I have in the pole barn. I am having the floor prepped for a 2 post in the middle bay and I got thinking that these traditional drains and slope to them might be problematic with a 2 post. In talking and looking around at options I saw some people do a trench drain near the garage door and slope the slab toward that. I spoke to the CFO (Wife) and she liked that idea as well.
Doing some searching and I see a lot of people mention this type of drain and say they are very expensive. I assume they are talking labor on setting these up. Is that the case? Sure compared to a simple floor drain the trench by % is a big cost jump but in terms of the overall garage build $400 in drains is a drop in the bucket and I think worth it. Even if it added $1000 to the project factoring in labor and supplies that is still under 1% of what we are doing.
On to my main questions. If I went with a product like this. Not 100% sold on this one but they are all pretty similar.

I am thinking two sections per door. So if I went with this one, buy the 5 pack and a single pack. This would provide 6.5' of drain per door. I would probably have a single exit, can I daisy chain them together and maybe do a sand trap at the end? Maybe skip the sand trap as there isn't going to be much going down there. I am thinking of changing the discharge so that it comes out the South East corner of the building right next to last garage door so the discharge pipe would be 4' at most. I have a pressure washer and will have water in the garage to where I could blast them out in the spring. I have read that people state they let a lot of cold air in during the winter months, again short run so I could put a trap in the pipe before exit and probably could blast away any sand that makes it down there with a hose or pressure washer.
As I mentioned I have a single drain in the pole barn now that is a sand trap. I clean it out maybe every other year and there isn't much in it. Though I only park one vehicle in there and push melted snow and ice toward the drain. The big difference is the slab isn't heated in there so it carries more sediment to the drain. The exit is also a lot further away.
