Hi all, I've been reading and learning all about the fresh, gray and black water tanks. Fresh water and/or filling up the gray tank seem to be the main drivers of having to pack up and leave your dry site (assuming the gray tank cannot be emptied on-site). Our Ollie will have the composting toilet option since we plan on boondocking often. I confirmed with Oliver sales that the black tank is still installed and just not used, so I'm thinking that it would be great to take advantage of that to increase the capacity of both the black and gray tanks.
Has anyone with the composting toilet ever done anything innovative with the spare tank?
Based on the assumption we will always have filtered and/or bottled water with us and will never drink or cook with the water from our fresh tank, would this be feasible:
- Pre-campsite, fill both the clean fresh and black water tanks with fresh water. So 32.5 + 18.5 = 51 gallons of fresh water to start with.
- when 18.5+ gallons have been used from the fresh water tank, transfer / pump the fresh water in the black tank into the fresh water tank (essentially, refill it back to 32.5 gallons).
- transfer / pump 18.5 gallons from the gray tank into the now empty black tank to make room for the new water in the fresh tank.
- leave campsite when there is no more water in the fresh tank and the gray and black tanks are both full of "gray" water
- Empty tanks in a legal place, rinse, wash/bleach and repeat.
I'm looking into various water storage solutions and before I buy anything I'd like to see if this is a possibility. Any thoughts on this appreciated!
Thanks!
