Does using a sprinkling system save water?

Does using a sprinkling system save water? I wonder if having a system that is on a daily timer will save water as opposed to bringing out a portable sprinkler?

Sprinkler system can't save enough water, but some part it can save water and time. There were timers that can start and stop tehe pump also rotating sprinklers are enough for watering around the garden.
