Leak in basement around PVC pipe through foundation
 

I have a large diameter PVC pipe which exits my basement for the
septic.

When it rains it leaks around the pipe.
The pipe looks like it was sealed with concrete.
I am assuming I will need to chip this concrete out from around the
pipe.

But, what type of sealer should I use on the pipe?

how deep is it from the outside?

I would try to improve outdoor drainage, do gutters downspout etc dump
water in this area

It is about 3 feet down.

I have been working on the grading and gutters, I thought I had it all
fixed now.

Dig around the pipe outside the house to expose it, surround the
pipe/foundation interface with tar, cover the tarred area with an insulating
layer (such as a board), then refill.

If it is only 3 feet, I would definitely dig from the outside as well,
and redo the sealing there, too. If possible, you want to keep the water
outside the (usually black tarry stuff) water seal on the outside of the
basement wall. *If you just redo the inside, that may slow it down, but
if water is still getting into the wall (especially if it is a block
wall), you will likely get leaks, or that white crusty stuff, elsewhere.
How long are your arms? You may not have to dig a very big hole- just
need to expose all the way around the pipe, far enough to brush all the
dirt off, and apply the new goop. Good idea to eyeball the pipe, and
maybe drop some food coloring down the toilet, just to make sure the
pipe didn't frost-heave and crack, and that sewage isn't leaking back in.

This is a poured concrete wall.
I will have to see what it will take to dig down.

I spent more time looking today.
The back yard patio is poured over the pipe in this location.
BUT there is a large pipe opening with no cover sticking out of the
poured concrete.
I wonder if it is leaking around the base of this pipe?
I don't even know what this pipe is for.

Is the top of the pipe threaded? If so, it is probably a cleanout port.
If not threaded, so kind of air vent. (I'm no septic expert, somebody
will jump in shortly...)

I looks like a poor attempt of a vent.
I am not sure if a vent is needed here..
The clean-out is on the inside of the house.
