Under ground water leak

I've been watching this water leak for a few months. I thought a leak and others thought just from a drip from the filters above.  It finally had a little stream of water even if ever so slightly.   The ground here swallows water very fast so very easy to miss a small leak.  I vaguely remember the ridged black pipe we were using was just a little short and not flexible for a turn like this.   It lasted a couple years but eventually decided to disconnect. May have been effected (was effected) by settling under the water spout.  

A two day project and more digging than I want.   Had to decide on the flexible hose to make that connection because the rigid black pipe is not flexible and basically brain dead.  20 pesos a meter for the clear stuff, very flexible and as strong as the black stuff. Actually both are easier to work with if they sit in the sun a few hours. The weak part are the hose clamps that corrode and become useless. A soldered copper pipe from one end to the other is a better solution.
