New inground small reflecting pool

Hi,

I’m in the process of building a small 16’ x 9’ x 2’ high inground pool and am close to having the frame done to pour the concrete walls and floor. But before I pour am trying to find out what shape/size holes and how many to leave in the wall and what pump/filter system you all have that would be a good fit for this size pool. Also, would probably need a floor drain that would exit out into a field when it came time to drain for winter. Can you help? Do you know what openings I need to leave in the wall before I pour and can you supply the pump and filter system?

Thanks!

Mike
