That is a plumbing vent pipe. Many times the vent can not go through the roof and out so it is just vents to the outside through the ground. This is usually true with any plumbing fixtures that are installed below grade. Like a basement apartment. It has a elbo pointing down so rain and other things can not enter the pipe.

Since plumbing vents are required to vent above the roof, I would say they are for an energy efficient furnace/AC unit. They use the pipes for fresh air and exhaust.

My guess would be an intake and exhaust for a high-efficiency gas furnace.
The fact that there are two make the idea of it being a plumbing vent unlikely -- no reason for two that close together.

more than likely they are connected to a underground storm water retention system if the system gets water logged then the water would flow out of the pipes onto the ground.

One possibility is ventilation for a cellar, or they could be growing SOMETHING in the cellar, the elbows keep out the rain to a degree, or maybe it is a spy tool for listening to slugs mating in the garden!

Sounds like vents for a septic system.
