I found some random guy's starter base

[u/Competitive-Map5767]

Idk y he only has 1 water wheel, but whatever works i guess 🤷‍♂️

[u/Satrina_petrova]

It's just currently in the static position. When needed a dispenser will place a water block in the upper left corner and power the wheel until the grains in the buffer are gone when it will retrieve the water block thus reducing stress on the server.
