This is what I use...
You buy the water plus $6 for deposit on the jug. Do what ever with the water and use the jug for your
SW purposes. I have a dozen plus 3 other 5 gal jugs of different design to go out and collect
NSW. If you want to keep from leaking cap the top with plastic bag and a rubber band. BINGO, cheap 5 gal water jug. The new design even has built in handles on the side.
