I have an older concrete pool and from what it looks like possibly made of cinderblocks. Currently my pool has a liner in it due to major cracks in the structure of the pool wall itself. I am toying with the idea of next time I need to replace the liner just repairing the concrete and if possible turning it into an infinity pool. I am uncertain what type of pool my current pool would be classified as, it is a shallow in-ground pool with a water depth a little over 5' but the wall of the pool is partially out of the ground on all sides, from the most visible side it is about 1 foot high and to the back side it is probably about 2.5 feet up. This design makes me think it might be possible to just lower (cut away) at the backside or just add more concrete to the other sides.
All that aside looking at other infinity pool in hotels and other places, to me it looks like pretty simple idea, the water overflows into a collection camber with two sets of pipes one set of pipes that actually feed the water to the filter and another set of pipes that work as a sort of overflow to drain the water from getting to high. Over the collection caber you add some grating to keep out large debris. Have the return the same as you would in any other pool. Please someone correct me if there is more too it, I am just basing this off of what I have scene and about 10 years of saltwater aquarium hobbyist work.
As for my initial question regarding my pool being converted into an infinity pool does this seem like a possibility?
Thank you for looking!
