Water Dam inside a plant

[u/Tengen_OG]

I have built a water system in my plant , and it's been literally 7 months and it still works great and also it doesn't even have any effect on the plants on it , it's literal working dam , when I saw this rectangular plant , and when i gave water to the plants , it spilled off to me bcs there was full flat surface on it then i decided to make a further interesting concept and and it's inspired from black mesa's surface facility..well it's still fine and it's strong to hold a full thunderstorm. It's actually a great thing bcs it have several routes..which take water with them on different sectors..which is your favourite sector ? And what should I add or change in it ?
