We need new septic system..

Please help our family we lost our house  to a house  fire in july. We had our house rebuilt and have almost overcome this tragic  situation and moved on with our life and we now have moved  into our new house and we now have found  out that our septic systm  has been abandoned  and filled in with sand..we are out of money and we now have no way to shower  or was dishes let alone go to the bathroom. We are asking for alittle bit of help before winter comes and freezes the ground and then we will have to wait till spring. We have been through so much in the last four months  we just want to start over and bot stress anymore. Thanks for taking time to read. Merry christmas and happy holidays.
