This is pic1000 the source of it #wakeupkitty and @freewritehouse I see water line, and some amount of water flow in it through down. Behind water line I think have a garden because I see also greenery. It near a house. I feel the house holder he supply water into garden. Story this water make possible to life, no one live without. This house owner to taking interest in greenery so he make that water line for supplying water to his garden which behind his house. He use his technic for transfer water one place to another. He doesn't want to wast his extra store water, so he transfer it to his garden.
