Just a bit of additional info... The estimated price of a septic system in this area can run between $30k and $50k when all is said and done. Part of the reason for the high cost is we are looking at building a large primary house and then a shop with a secondary living area so the septic will need to be sized quite large. That type of coin just isn't in the cards currently plus we couldn't even start until we have a full site plan figured out and that is going to take a couple of years.
I'm thinking of something more like
this. That would give me enough capacity for a week at a time and it could fit right under the trailer making it easy to use. I will just transfer the waste to this when the trailer tanks get full and then when this is full, have a pump out company come and service it. Grey water I will probably just let water some trees nearby an make sure we use appropriate biodegradable soaps and such.
For fresh water we would get a similar tank approved for fresh water. There is possibly a spring on the property (have to confirm) so we might be able to refill from the spring. If that isn't possible, we will have to look at a water delivery service.
I'm looking at spending maybe $1k to $3k to get going. This setup is intended to be temporary, 3 to 5 years tops with us using the trailer maybe for 1 to 2 weeks each of those years.
