is probably one of the best things I have ever built. I work with a boys group
called Royal Rangers, which has 2 main campouts each year. They are normally
held out in the middle of the field with only a garden hose as a water supply.
The water cannons are setup on a small slope so all the water drains into a big
hole I dig. This holds the water so it can be recycled and used over again. I
have a new design I want to try which will use 2 pumps. Then I can dig a small
hole. The one pump will pump from the hole into a large trash can next to the
hole. This will be the above ground storage. Then I will just a pump from the
trash can to operate the cannons.
In this video I super sized my water cannons to 4 on each side. Normally is has 2. In the past I used a 1hp sump pump but in this case I rented a gas powered water pump. Because the hole was so large to store the volume of water needed I did not have a tarp big enough with me to put in the hole, hence all the muddy water
