Comments from the Finger: So, this seems like it belongs in an elemental pack of some sort, but I really don't see it like that. Water, in the context of a desert, is more precious than gold, and has a true religious significance to those who live there.
In the heat of the endless wasteland, water is precious, and access to it is key to survival. Priests only swear to the Water Domain in truly hostile environments, where water is scarce enough to command divine significance in the minds of the people. In these places, clerics which can summon elemental water are the bringers of life to utter desolation, and are often the only barrier between the unending heat and lethal dehydration.

Spring of Life
Your holy symbol is little more than a flask from which pure water flows. At 1st level, you can cast the spell create or destroy water once without expending a spell slot. After using this ability, you must complete a short or long rest before using it again.
At 8th level, you can cast this spell at will.
Channel Divinity: Refresh
By 2nd level, you can expend your Channel Divinity when you take a short rest to summon forth perfect elemental water from your flask. Each creature that drinks from this water while taking this short rest immediately regains one expended hit die.
Channel Divinity: Moisture Shield
At 6th level, you can use your Channel Divinity as an action to form a 5-foot-radius sphere of churning water around you, while you concentrate on this effect for up to 1 minute. Ranged weapon attacks targeting you or any other creature within the sphere have disadvantage.
Additionally, as a bonus action while the sphere is formed, you can lash out with a tendril of water from the sphere. This acts as a whip that uses your spell attack bonus for attack rolls, adds your Wisdom modifier to damage instead of Dexterity, and can originate from any point on the surface of the sphere.
By 8th level, you gain the ability to infuse your strikes with divine energy. Once on each of your turns when you hit a creature with a weapon attack, you can cause the attack to deal an additional 1d8 cold damage. At 14th level this increases to 2d8.
At 17th level, you have been blessed by elemental water, and as a bonus action can assume a form composed of water. For 1 minute, you have resistance to bludgeoning, piercing, and slashing damage from nonmagical weapons, and you can't be grappled, paralyzed, poisoned, restrained, or prone. After using this ability, you must complete a long rest before doing so again.
