Their are 2 parts I can remember.
Escaping in a sewer, finding hidden people/children down there, fleeing into the desert
finding a desert city and a ship that sails through the sand

I have looked for this book many times throughout the years, probably read it about 12 years ago. It sticks with me but Ive never found it or recalled extra details.

The Wind Singer?

Alyssa, what's the genre (which we need to add to the header/topic title) - e.g., adult or teen, fantasy or historical fiction?

[SBC]

Maybe The Waterless Sea by Kate Constable?

That doesn't sound familiar, I looked at the Wikipedia. I did go ahead and order one from thrift books so we will see. Thank you for the suggestion :)
