Where does all the poop go?

So septic systems are a bit different here. A lot of times if the people actually have plumbing, the pipes just empty out into a river. A really really good septic is a hole dug all the way down to the water table, yum! But if your professional like we are, you build a 15'x15' two part decomposition chamber completely water proof. These guys dug for about 2 weeks what a back hoe could have done in a couple of hours. So... this is where the poop goes. Everything empties out into this tank which is right next to the bathrooms and into the first chamber where it sits and starts to decompose. Slowly the sludge enters into the next chamber and settles at the bottom while the liquid then passes through pipes run in the ground and empties into another hole where it will sit and filter into the ground. The other pictures are of our progressing classrooms and our beautiful gazeebo. The next two classrooms are under way!
