What type of floor drain should I construct for my pole barn? I am not going to install running water , the size will be 40x32, and I am in a rual area and I don't have to contend with city codes, just need a system to drain water and snow from my vehicles when there parked.

I put in a 3" pipe with three floor drains for my 34x70 pole barn, plus one in the compressor room, and a sink drain for further use. It is run to a rock filled pit, with an overflow to the french drain system.
I spend a few hundred bucks on the piping and fittings and have plenty of fittings left over. I went from a trap per drain to a single trap at the end.
Would you like my box of left over fittings at a deep discount?

If you are not hooking up to a sewer or septic system you don't need the traps.
Their purpose is to stop the back up of any sewer gas into the building.
If you are just draining to air or a rock filled hole you will have no sewer gas to worry about.
If you have to worry about freezing 3 inch is the smallest you want to go.

I put a bell-trap style floor drain under each vehicle bay in my 36x26 garage. The bell traps do a good job of catching sand/salt/crud that melts off the cars in the winter and are easy to clean out.
All 3 floor drains tie into a 3" PVC drain line which daylights outside on the downhill side of my garage.

Hey all, first question on here after hangin out in the shadows. HA. I dont mean to hijack the thread either. Im planning on floor drain in my 40x38 garage. My question is how much slope should the floor have to a drain in the center of the parking side which is 24x38? Just for snow melting or the occasional inside car wash. I dont want my stuff rolling towards the center of the garage hahaha.
+1 on the below. I used the same, but not in a pole barn. Works great, can't imagine winter life without it.
I have about an inch and a half of slope over 12 feet. It's approximate. A marble would roll to the drain, but a creeper or mechanic's stool does not.

I used 3 round plastic drains (1 per bay) in my garage. Those are connected to 3" Schedule 40 PVC that runs out the side of the garage, through the footer. The 3" crosses my driveway and "daylights" in a 12" X 12" grated box. The box grate is under the level of the floor drains by about a foot and serves as an overflow. A french drain exits the box. It's about 12 feet long constructed of black perforated pipe, and is sloped down into a trench backfilled with crushed stone.
As far as slope in the concrete floor of the garage...mine has about an inch back to the drains.

typical slope is 1/4" per foot of horizontal travel...so a 4' would drop an inch, 48' would need a foot.

I didn't put in any. Water either evaporates or goes out under the door.

In my 30x40 I only put a drain in the bay that I thought would ever have a car parked in it that would be wet or have snow/slop on it. The other bay will have a lift, and the rest of the garage will be workshop area, that is all perfectly flat. In the open bay, we just used a regular old 6" plastic round drain.
