Water is one of the most important aspects of life all over the world, arguably the most important. So it is critical to have a robust infrastructure that can handle the demands of water, whether they be for survival, or agriculture or it's million of other uses.

This OSAT is a garden hose splitter that can be used to split water streams from a common garden hose nozel. [1]. This splitter can be customized to any desired size, and can be paired with multiples of itself to further increase splitage.
Skills and Knowledge Necessary to Make the Splitter
No special skills necessary, just use of a 3D printer.

Common Problems and Solutions
Make sure you check what sort of hose you'll be using. If you're in the US it is most likely a GHS, outside of the us it is BSP.
Cost savings
The cheapest I found was 8.99. Although it also had valves. But chances are you can get around not having valves.
So cost saving is like 6.50 per unit. That's a 620% saving!
