Water through outside pipes

In a lot of homes in Guyana, there are tanks for storing water for use in the home. The tanks may channel/run the water to the kitchen sink, bathroom, and so on, but it is different from the way water is made available through the faucet (“kitchen sink pipe”) or bathroom in the US. There are also outside pipes that provide water (separate from a tank - maybe in Linden mostly). I like the outside pipes.
