In last years California, have seen heavy casualties because of the forest fires. In the latest forest fires, 77 humans died, more than 600 lost and a lot of houses burned. The cause of these fires is that the recent years have seen a drought. However, It appears that there are some problems in fighting the forest fires.

In this essay we will talk about a new method that is required in fighting to forest fires. The main feature of this method is that installing a moving sprinkler system over the forest. Depending on the size of the forest, a sprinkler system, which can grow up to a hundred decare, will move on the forest with hanging rails.This sprinkler system will move on fireproof feet and rails and will be guided by a hydraulic system wherever the fire is.

The system will be fed up from the nearby lake, sea, river, underground source or city fresh water system. The power supply needed for the system's fire pumps and hydraulic system pumps may be wind, solar or urban electricity. The installation cost of this system will be very low besides the damage from fires.

Considering that forest fires will continue, this system primarily should be installed in regions with high-risk for fires.
