How To put most basic drain into new garage slab

[Jawgarage]

Working on finalizing the plans for a 2 car addition to a current 2 car detached garage. There is no plumbing in either and no plans to add it. I do like the idea, however, of being able to wash off my car while in one bay of the new garage and have seen some done with a floor drain. My question is if this kind of a drain for water runoff needs to be plumbed and drained elsewhere or if I can basically have the mason add a drainage cover and grate and somehow build a small basin for the water to drain into? The ground under the garage is extremely sandy so I'd expect the water to simply drain into the ground. No idea if this would pass inspection with building codes however and am not looking for any problems. Just want to consider all options BEFORE it is built!!!!

Its best to ask your local permit folks first, but I think you could call it an emergency floor drain and run the drain pipe over to the side of the slab and into a dry well. It makes a lot of sense in areas where you park snow-covered cars inside a garage. The pipe running to the outside would give you the ability to include a clean-out, so you could clear out the drain pipe if it got clogged. You can buy pre-made dry wells from HD, and if installed correctly in sandy soil they should drain very well. The pre-made dry wells hold about 50 gallons of water.
