If am getting a 30 dale serrif sale letter in mail, and have health dept septic problem, am I liable to fix it?

My house has had ongoing septic feild sewqge on the lawn for 9 months or so ago, and would cost $7500 to dig a new drainage field.
Since that time, I have been divorced, thru bankruptcy, and now pending serrif sale letter, 30days for me and my 7 kids to get out of the house and find places to live between me and my ex.
I was told to take short showers, do laundry at laundrymat, have the septic tank pumped a week before the health dept. inspects the septic...hopefully it will be dried up and pass, then it will be the banks problem. Is this right?
Do I have to fix the septic, just dry it up to pass, or do I have to do anything?
I am just soo frantic over this cause I cannot afford it and still get a place to live.
Also, do I have to take care of the lawn, house after moving out?
