Septic system without d box and without manifold.

What can I do to repair such an old system???

Any answers or questions to help me learn will be replied to.

Thanks!septic

If you do not have a distribution box or a field, do you have a "cess pool"? If so, it is NOT an old system, because they are being installed around here every day. In fact it is the preferred system unless the property is sitting on a bed of rock.
