Its not that they don’t want people in the countryside.
But with some living in trailers and dumping their grey water wherever they please, it gets nasty, and the water table is low there (think punchbowl), septic must be researched properly.

My place had an artesian well, flowed year round.
But septic would have been more of a challenge.
It would have had to be on the opposite corner of the property to be safe and functional.

The SLV is a whole different place, think of a third world country transplanted and you’d be close.

This is a place where hanta virus is still going strong.
