Bring 5 Wastewander Water Pouches to Spigot Operator Luglunket in Gadgetzan.
Greetings <name> - the name's Luglunket, and we've got an important job for you if you're up for it! Huzzah!
Nothing would please me more as a seasoned spigot operator to take any Wastewander water pouches you might find out in the desert. That's our water anyway - the nomads have just stolen it is all! The Gadgetzan Water Company will offer you an official care package for every five you turn in. Most importantly though, you're helping Gadgetzan help itself!
