I know of a cabin that has never had plumbing in it of any form, kitchen or bathroom. Could someone please advise what is would cost and involve to implement a very simplistic BUT year-round system to accomodate 2 (water conscious) people fulltime. It would have to be reliable in winter temps (average -5c but in rare circumstances as cold as -25c). There would be quite low useage (no laundry/dishwasher and river water very close for non-human usage). A well/septic field is not an option because of environmental restrictions. I am VERY inexperienced with this topic but thought perhaps a water cistern/holding tank (water delivered) and septic tank to be pumped out regulary?? All that would be required is very simple kitchen sink (to double as bathroom sink), small toilet, and very small shower (to use every other day). The amount of space required for toilet/shower "room" (neither of us are large people but small cabin) and the cost of the project are the 2 major factors regarding whether this endeavor is even feasible. Perhaps I underestimate the complexity of this question for this forum but ANY feedback would be VERY appreciated. THANKS!!
