I have some friends that live over oil shale. The water is half oil and undrinkable. They tap into springs for drinking water and use septic tanks for cisterns. Pretty much the standard way to go in south eastern Ohio.
Have any of you guys built a cistern ?
I think those folks are just describing using a tank that is NORMALLY used as a septic tank for a cistern.I was wondering what you mean by cistern? Out here a cistern holds water for drinking or household use. A cess pool is for gray water that comes out of your septic tank, or sometimes a cess pool is the septic tank. It seems to me some of the posters are talking about both.
