Building Art Stuidio on Concrete Slab - Drain Access Question

Building Art Studio on Concrete Slab - Drain Line Concern

Hello All,
I want to do a floor drain and a large utility sink. Basically a car-wash, where at will be going on. I'm nervous about burying drain lines in a slab. What are some ideas for giving access to the drain lines and also doing proper drains for this kind of application?

Any input will be greatly appreciated.

TIA,
Molo

1) Look into a sand/grease interceptor....
2) The lines will be buried UNDER the slab I hope...
3) Check out the tie-in's invert before doing anything - make sure you have the depth to do the plumbing...
4) Draw a quick floor plan and layout of existing plumbing with dimensions for us to assist better... We cannot suggest anything concrete without "plans"...

If the drain lines are installed properly you do not need access to them once the slab is poured. If they are installed so you need access to them, then you should have had a plumber install them, or at least a better plumber.

No specific plans at this point, basically a 24' x 24' square building on slab with water and sewer about 20' away at the street.
There are no plans because I want the drain lines to be a primary consideration. The floor drain and quite possibly the utility sink will see dirt, clay, sawdust, etc.
With that said, I don't want the drain lines to be slapped in or not given adequate consideration.
Does anyone have suggestions for designing a working, relatively trouble-free drain system that will have to deal with these kinds of materials?

TIA for any advice,
Molo

You could use channels in the concrete covered with a grating. Trench drain or something I think it's called. Then you can get to them if need to be.

troff drain like Lakee911 said might be a good idea. I would make sure you have clean outs. maybe a catch basin to keep the dirt etc... from causing problems down stream.
