I'd like to suggest something more costly, but perhaps more cost-effective in the long run.

What I use for water storage is the Scepter GI Runt (2.5 gallons). These things are very heavy-duty plastic and intended for military, expeditions and such like. No spigot. Large pouring spout with a smaller one built into it.

I have six of them, all still in fine shape after three years.

Scepter also makes a 5 gallon version, same design.

I found them at brigadequartermasters.com.
