I'M HAVING DRONE ENGINE TROUBLE!!!
james_s:
To carry such a heavy load I would definitely go with fixed wing if possible, that's not hard to do with electric but internal combustion will get you longer range. You'll probably need something like 1/6 scale aircraft.

The word drone has many meanings to different people. If you mean a machine that can operate without a person on the machine that acts autonomously or by a remote controller, the answer to your question is many fold. Without answers of your own to define better what you are asking, there can be no one single answer.
1. Is this a flying machine, a stationary machine, or a machine that travels on the ground?
2. What is the means in which you want to move 10 gallons of water; i.e. a quart at a time, a gallon at a time, or the full 10 gallons at once?
3. How far do you want to move this water?
4. Assuming this is a flying machine, what configuration are you attempting to use; i.e. fixed wing, helicopter style or other?
5. Do you already have a machine in mind or in your possession that you want to use?
6. How much budget do you have for this project?
7. What is the goal of this machine, other than to carry 10 gallons of water; i.e. contest, curiosity, want to DIY, humanitarian?
8. Where will this be done, inside a building, outside in the open air?
9. If outside, what type of climate; i.e. frigid, moderate, equatorial, humid, hot?
10. Are there any other considerations that you have not mentioned?
This sounds like a cool project, but, without you further explaining and giving more requirements, you can't really expect to get much useful feedback here, as many of us are seasoned engineers and will expect you to be at least a small percentage as thorough in your requirements as we are in our projects. You seem to be a beginner that wants to learn, and the first thing to learn is to be very thorough in your requirements.
Hope this helps...

My son is an internationally ranked drone racing pilot. We do a LOT of design, construction, testing, and flying here. My very educated response to the OP's post is:
"If you have to ask such questions, you are not qualified to build nor fly such an aircraft."
I honestly don't mean to sound insulting. I'm deadly serious. Anything powerful enough to carry 10 gallons of water (that's over 80 pounds!) as a payload is a serious threat of injury or death to anyone nearby. Racing drones typically spin five inch diameter props and are less than 300mm across, yet we call them "flying lawnmowers of death" and erect protective screens for the pilots and audience at competitions. Anything that can sustain 80 pounds of payload is going to be significantly larger and more powerful, with commensurate risk of injury. I'm not kidding... we're talking amputation of limbs and instantly fatal injuries.
Think a really long time about what you're considering, and if you still want to do it start with small platforms to gain experience. I'd suggest 2-3 inch props with appropriate payloads, then scale up. You need familiarity with the control hardware and software, for example, and that experience will scale up to larger platforms. But while you're gaining experience you won't be hurting or killing yourself or others.
Once again: I'm not exaggerating. I'm not cavalierly tossing around words like "injury" and "amputation" and "death" just to get attention. The motors/engines and rotary wings necessary to transport 80+ pounds are significantly stronger than the human body. Don't get hasty and make a permanent mistake. I encourage your enthusiasm and reseach into this field but do it slowly and responsibly.

I suspect long before death and dismemberment the $20-50k+ wallet shock to build it may ring some alarm bells before it gets to leaving the ground and if the CAA lets that happen either.
What Drones or are not to people is misshaped by the media and junk mail sub $100 ones in glossy colour.

Not to mention the court costs and attorney fees if someone gets hurt.
