The diy 3 barrel septic tank system for your cabin or RV. 55 gallon drums!

My DIY homemade septic system is finally finished! I used two 55 gallon barrels, one 3 1/2 inch PVC pipe, one 2 1/2 inch PVC pipe, and some exterior caulk. The digging was the hardest part 😅
Also, I would add some water to both barrels for weight so that you won't risk the barrels lifting out of the ground from heavy rainfall, since they are basically giant air bubbles when empty.
