We have one Aqueduct, looking for a second. In our quest for the ultimate water collection bag to replace our 5 gal plastic Reliance collapsables, this comes close. (We also have used the blue Reliance Aqua-Sak. Nice material, but needs to be filled through the small spigot end opening.)

The Aqueduct holds nearly 5 gal and is a soft but sturdy material, not as prone to the annual cracking and leaks of the Reliance. Also, it fills with a single scoop mid-lake through the roll-top opening. Some dislike it based on a spigot that can seem to be a bit fussy, but we got used to it and it provides a good flow.

They used to be ~15-20 bucks and readily available. Now, there is just one supplier. Doubled price + shipping from Canada + membership requirement makes purchasing new a bit too spendy.

If anyone has an Aqueduct bag (white, not the black shower bag) that they are willing to part with, I'd appreciate it.

You can modify the top of the aqua sak if you know of a place to have it restitched.
