Cyndy I believe I have that kind of system....there is no sewage system where I live, and the old type septic tanks are not allowed. My system works by a small motor (next to the hous) and it aearates(sp) air thru the underground tank, and out pipes to the bayou in back of my house. It is legal to have this empty in the bayou...they tell me you can drink the water that is released in the bayou. Thjank you, but I will pass on that. The only trouble I ever have is with the roots clogging up the pipes, and the big tank has to be drained ...but not very often. I put root killer in 2x a year. Hope this helps.....
