What are those green pipes sticking out of the ground near the stream? And shouldn't the stream have a cement bottom to keep the water from draining through the mud?
I'm not educated in construction, but I think the green pipes look like the clean out pipes in our yard. I'm not sure why you would need three in close proximity though. Clean out pipes are installed so that they can unclog pipes when someone drops something in the toilet. For example: The previous owners of our house flushed a wash rag down the toilet which clogged the pipes backing up the greywater running from the house to the sewer. If there is a long distance to an access point it is very difficult to snake out the clogged spot. It can save having to dig up your yard or jackhammer your driveway.
I imagine there has to be a barrier for the water in the stream as well. If not those lanscaping rocks will also sink into the soil.
