Need guidance on code compliant septic connection
Hello there!
I purchased a house with an apartment over a separate garage and recently found out that the apartment was pirated in. I am now tasked with bringing the whole thing to code. One of the things I have to do is get a conditional permit for the drain that runs across the yard and connects to the main septic line. The issue I'm having is getting someone to actually come out so I'm starting to lean toward just fixing it myself and calling the inspector out.
The length of the line from the garage to the septic line is about 80 feet. It's 3 inch in diameter and has only one cleanout, right at the point it exits the garage. I was wondering if someone could tell me what a drain line of this type needs to include to be code compliant. Here's some pics, apologize for the water, the septic company has left me hanging a week and we're getting a ton of rain.
Stats:
80 foot of 3" drain line
1 cleanout, 6 inches from exit of structure. No other cleanouts
Sweep 90 at structure, sweep T at septic line connection

Your picture links point to amazon but there is nothing there.
Try posting here directly...... how-to-insert-pictures.
I can't help you much with your problem there. I didn't think you could put two buildings on a common septic system. Did the inspector come out and survey the situation ? Ultimately what you do will be up to him.

Hi there Pete and thanks for taking the time to help. I didn't stop to think about the source not being vuewable. Sorry about that. It doesn't look like editing posts is allowed so I'll just post them below this message.
RE: your question: It will be a conditional permit. In my case, it means that regardless of the number of bedrooms on the property(4), the property will only be legally able to support 3 bedrooms(or more specifically, 2 people for each of the 3 bedrooms the system was originally permitted for). This is fine with me, I just need to make sure I do my best to try to make the physical system meet national code. Since I'm tired of waiting on someone to come out and do this, I'm going to try to make the necessary changes. So far, I think I've determined that it needs a cleanout every 50 feet of pipe, so I'm going to add one but I'm wondering what else I need to look at before calling the inspector.
Again, sorry for the messy trenches. I promise they were neat and tidy when I dug them

Pictures look good.
With all the rain lately it's pretty hard to do anything underground without there being a muddy mess.
The others will stop by and add advice.

First, septic's are generally sized according to the number of bathrooms although the number of bedrooms is loosely associated to that as well.
There really is no national code for septic systems, many states dont even have guidelines, if they exist it's at the county/local municipality level, they are the ones you need to be talking with!
The only thing that really screams out with your pictures is all that drain line is flat and shallow. It doesn't look anywhere close to having the min (absolutely min) 1/4" per foot (thats 20" for you) so your going to have some flow/blockage issue. Not to mention what will happen when that line freezes solid in the winter time!

The first step is to talk to your Building Inspections and Zoning Departments. You should have permits in hand BEFORE beginning the work. While it is not 100% required going for a permit after you've already begun work can start you off on the wrong foot with the inspectors. You also need to know up front if they will permit you to keep the illegal bathroom.
Marq1 brings up a very good and very obvious point. The lack of fall in your drain line. How much fall do you have between where the drain pipe exits the garage and where it connects to the septic? Is a gravity line even possible or do you need to install a collection pit and pump?

Not that is related to the question, how was this "apartment" plumbed originally?

That of course doesn't resolve the issue of freezing which I hadn't thought of.
I'm sorry, I'm not sure I understand.

Just curious, was it somehow plumbed to the septic tank originally or even hooked up?
#12
I know this is off topic but it's an intriguing situation and I hope your able to resolve.
So how was it plumbed before vs what your pictures show?
I'm trying to wrap my head around the need to install an 80' line for something, right or wrong, that was somehow working for a decade.
the apartment has been dumping into the main house's septic tank the whole time

Hi there guys, just wrapping this thread up. $4500 later(including the preparation and submission of the state dept of health package), an entire new line(enlarged to 4") was installed. They terminated the original connection to the main septic line and moved the connection directly to the tank, added cleanouts and placed the properly spaced cleanouts. I'm free and clear now to start tearing apart the apartment above the garage to start the process of bringing it up to code.
