Nice water caustics!
I agree. I didn't made the design, just the render, but I guess they would say that a good lawn mower with aspirator would solve the problem.

The water caustics are all kind of tricky; the first pool uses Nuno's method or something similar: two water surfaces; one real water but hidden to camera + one AGS that provides reflections and shows the caustics produced by the real water; it has the problem of showing dimmed unrefracted geometry too.
The second and third are made out of two renders: the main render is made with plain "real water" and the second would be the same but with water hidden to camera (so it shows unrefracted geometry but fast and nice underwater caustics. They are blended in post; the second one is deformed and rippled in post too to match the refracted geometry of the first one.
