I'm an Architect. I have a raised overflow pool in my project with approximately 200,000 gallons of water. Yes, it's massive.
We need to make our pool looks as if it's floating. So we're working on hiding the gratings to be a minimal slot hidden under the pool's stone edge.
The question is how we can calculate the gutter size hidden under the stone finish deck? We're afraid that while the pool is splashing with huge amount of water _since too many users will be using it_ that the gutter won't be sufficient and the water might come out again out of the drain slot.
