Black and or Gray Tanks holding...

I guess time well tell but about how long will it take a family of three to fill these tanks?

I am certain the gray tank will fill the fastest but just how fast...

any helpful ideas about this well be great.

I know that if it is just hubby and myself that the black tank can go at least 2 weeks (30 gal). Gray, well that depends on how much I cook and have dishes to wash. We normally take showers at the bath house, ALL kinds of hot water and 20 times the room!

Take navy showers & use paper plates. That can reduce the amount of grey water.

Our 30 gallon tanks hardly ever fill up with 2-3 days of camping. If you are scared of the showers at the campground & wash dishes alot, just get a Barker portable holding tank.
We switched to strong, paper plates and good plastic silver ware & cups to cut down on grey water.
Seems like we can't ever get a good gauge of our black tank level, even after installing a Tornado. But it does clean alot of garbage off the black tank walls. I wonder about the 2-ply toilet paper breaking down, even with plenty of treatment put in. I keep seeing it wash out through the see-through sewer elbow.
Hope this helps.

With me, DH and 2 small kids, we fill the gray tank after about 3-4 days. I'm the only one who showers in the camper - DH doesn't fit and frankly, i don't care if the kids go w/o for a few days as long as they aren't truly dirty. (they're 5 and 7, they don't smell yet, lol) I usually wash dishes 2-3x a day, everyone brushes teeth, washes hands, etc.

Black tank takes a lot longer, i think we filled it the one time we camped for a week straight.

This past weekend, we only had electric - so i used paper plates and burned them in the fire, plus showered (and other stuff, IYKWIM) at the bath house. After 3 nights, gray tank was reading 2/3 full.

Some campers have 2 grey and one black tank, as mine does. The galley is in the front by itself, and the bath sink and shower are towards the rear. They are both 30 gallon, I think.

We also have two grey and one black water holding tank. We've lived in ours and have found that once a week we have to dump the black water tank and the grey water tank for the galley (we usually leave the shower's grey water tank open - with a full hookup site, this way we can take as long a shower as the hot water tank gives us)
