Rv garage with sewer hook up

Here you have to have a septic system designed based on the intended use by a certified engineer and have it inspected after the built is completed. My understanding is that the main differences between dumping rv tanks and plumbing in a house is the concentration of the waste water entering the septic tank. After taking a bath in a 2 person Jacuzzi tub you'll likely be dumping much more than a grey tank worth of water into the system. Also, the black tank is usually between 1/2 and 3/4 full, so let's say 30 - 40 gal. max, compared to 3 - 5 gal every time you flush the toilet in a house, no big deal. Then, I personally would say people living in their RV, or on a septic system in general for that matter, are much more aware of what they put down the drain, no harsh chemicals and ....., where some people on a municipal sewer system may think 'out of sight, out of mind'.
Your idea in regards to living in the RV while parked in an enclosed garage, I would not do it. If there is ever an emergency situation where you have to get out fast, there is no quick escape. When we had our 'garage' built, the RV (5th wheel trailer) was 'parked' inside when the building inspector came to do his job, he said "I don't care what you do after I leave, but think about it, potential moisture issues, structural (pole shed), CO gas from running the furnace and water heater, fire escape ...."

You are so right. The shop doors would be open along with an exhaust fan running most of the time. Safety first.

We did not put a septic dump in ours, however we have a macerator pump on our coach so we can, and HAVE, pulled the black tank hose to the septic cleanout pipe and dumped here at home.
99.9 % of the time we will dump at the campground before we leave, but it's nice to know we CAN dump at home if needed.

Here's our coachmahal.

Your septic tank stays full all the time. As you discharge into it the volume pushes the water already in the tank into the drain absorption system so you need to know how much your drain system will handle at any one time.

Depends on the type of septic system. Ours has 2 tanks everything goes into first tank and it spills over into second tank. This second tank has a pump with 2 floats when the level reachs the top float the pump kicks on and empties the tank to the second float.

Our tank is 1250 gallons with baffles on either side to retain solids. The liquid flows out to our leach field where it evaporates. I see no problem at all in using the system for an RV. If you were hooked up to municipal sewer they would give you problems but into your own once you get a general permit, there should be no issue.

You might need to call it s "cleanout" to get it by code in your area.

Never a good idea to let Black Tank free drain. Grey Tank is fine but Black Tank will soon have a build-up that can be costly to remove.
