Just looked up the water feature the client wants to use and the weight of the water fountain is ...303lbs. Might have to be a vault or basin to support that kind of weight. I have tried to find the specs of weight capacity of the vault below, but cannot find anything.
If I were to use a basin, it would need to be wider than the bottom tier of the water fountain which is 34" right? From what I can tell, the basins just collect water from the top and not from the sides like a vault. Large basins seem to be really expensive.
