The figure above shows a home surrounded by an AUTOMATIC Spray System that is putting up a wall of water that can stop a grassfire and embers. The water can come from a pool or a cistern or an above-ground tank.
At this home, a 600 gallon plastic above ground tank supplies the water. (Water from a household spigot is not nearly enough to protect a home.)
Note that the shape of the spray from each nozzle is actually a triangle.
Unlike rotary sprinklers, there are no moving parts.
When told to evacuate, the homeowner starts a pump and LEAVES.
The system will automatically start spraying when the fire is near.
The system was donated, by me, to the fire department in Mansfield WA, and was installed by me and by members of the local fire department.
The lowest cost version of the system uses hose to connect nozzles which are 10 ft apart.
The next section shows how stainless steel cradles can be used to bury the system in the ground. The nozzles are then connected by underground PVC pipe.
