septic

Im considering buying some property that does not have access to city sewage. Can someone tell me how many acres I need for a septic system.

After reading Redclouds thread on the down spouts it made me want to ask this question. Here at drilling site I work out of a RV Camper. The septic holding tank froze up and now is clogged up with TP and crap. Other then finding someone to pump it out ( I tried snaking it ) does anyone...
