HOSE SYSTEM TO DELIVER WATER AFTER AN EARTHQUAKE is described at the bottom of this page.


The above photo shows 200 ft of hose that can be used to confine a prescribed fire (RxFire).
There is a spray nozzle every 10 ft that sprays water onto the adjacent area.
The hose can also be used to protect a home from embers from a nearby fire, and also prevent
a grassfire from reaching the home.

The image above is a Hale fire pump that drives the hose system.
It can deliver 300 gpm at 70 psi.

The image above is a swimming pool that supplied the water to the Hale pump.

Earthquakes often break water mains. The quakes usually start many fires. If water mains are broken, the firefighters won't have water to fight the fires. Drinking water is also needed by the population of the earthquake region.

IFFC proposes
a very long portable hose system that can be rapidly deployed to deliver water to.
It can be delivered, by ground or air, to locations that have lost their water supplies because of earthquakes, floods, and large storms.
The system will be computer controlled so that it will be easy to operate.

The long hose system can bring water from 10, 20, or 30 miles away. There is actually no limit, other than expense, to the length of the hose system.

The figure above shows pickup trucks with portable diesel pumps and hoses on reels.
The pickup trucks have deployed the hose, from the reels, while driving across the terrain.

The hose contains a small gauge wire that supports a digital data network which,
by remote control, monitors and controls all of the pumps in the system.
Multiple pumps are needed when water is pumped long distances.
Hoses have limited ability to handle very high pressures, so that multiple pumps are needed
to boost the pressure at given intervals.

All of the pumps in the relay can be controlled by a personal computer that is driven from a control panel.
Once the hose and pumps of the system are deployed, there is no need to dedicate an operator
to control each pump.

The figure below shows that tractors can be used instead of pickup trucks.
The picture below shows an existing military system that delivers water and diesel fuel to forward posts.
The hose shown contains an embedded wire that is used to prevent static electricity from igniting diesel fuel.

We plan to use this type of hose in the proposed hose system. The embedded wire will support an Ethernet type digital network that performs the monitoring and control of all of the diesel pumps in the hose system.

The picture below shows a much smaller reel that can be used to deploy the proposed hose system.
 The image below shows that it is possible to deploy the hose system over very rugged terrain via a large helicopter.
