I know this is vague but nothing was labeled.
You’ll need to provide more information than that.
I know, it was a long shot. I’m trying to get info from the seller
How was the circuit labeled in the electrical panel?
Jeeez Jeff…technical, technical, technical… 
Looks like a well casing head and electrical service for the pump.
Rural inspection?
Never seen a septic tank that close to a home.
Ask the vender or vender’s agent for disclosure. “Please disclose is the home water public or a private potable water supply?”
Should be in the listing as well.
Masonry clearance.
Sometimes the difficult problems have the simplest of solutions! 
Water well head. Lift stations have a different setup.
Did you see a well water setup (pressure tank, etc…) inside the house?
I never got clarification from the seller. I do know that it has city water and the buyers were told it has a septic system. This was on a slab and I did not see any tank or typical well system.
Is this a house you inspected?
Yes, but I do not inspect wells or septic tanks.
I usually just identify if they are present.
Just shot in the dark, but there are septic irrigation systems that uses waste water to irrigate certain vegetation.
It looks like it could be a small pump inserted into the tank with the smaller PVC as the supply to the lines. As I said, just a guess,
Thanks guys. I’ll update you if I ever hear back from the seller or sellers agent.
Often they are buried in a concrete vault of sorts, in situations like that, around here…just food for thought.

If this is for sewage the buyers will to need to watch their diets because those 3/4" lines aren’t gonna carry too much solid waste.
Okay, I just found out from the sellers it is for a sprinkler system. Sorry for the confusion but thanks for the input!
