This type of pool is often equipped with an oversized overflow channel, sized according to the volume of the pool, which creates a striking infinity effect on one or more walls. The water flows directly into the open-air compensation tank, where it is sucked up, filtered, and then returned to the pool through the inlet nozzles.

This solution is particularly suitable for sloping terrain, with an overflow downstream, and for limited spaces that do not allow for the installation of a traditional compensation tank. The configuration allows debris such as leaves and insects to be quickly removed, conveying them towards the channel and keeping the water surface constantly clean.
