Distance is a function of nozzle velocity and jet stability.

So a small nozzle will project a fine jet a long distance, but if you want bulk water flow you will need a larger nozzle.

Putting a spin at the nozzle exit will increase jet stability.

When you have selected your nozzle then you need a pump to deliver the mass flow desired. Benoullis equation will allow you to match the maximum system pressure at any point to the maximum mass flow.
In general pick a pump that pumps a lot of water through a large orifice and then throttle it down to a small nozzle.

Remember to work out the power required to move that much water as well, otherwise your batteries will run flat before you get the system up to pressure.

Those are pretty vague constraints, Erazman. You could buy yourself a fire engine, but I suspect that that is somewhat beyond your budget.

The 1MW pump powering Lake Geneva's "Jet d'Eau" might do.
