How does an overflow pool work?

The modern overflow swimming pool system is becoming highly popular in contemporary design projects. The technical and design evolution of special ceramic pieces has enabled architects and construction professionals to use this system, in which the swimming pool water is constantly being renewed. Another major characteristic of these systems is the aesthetic effect of continuity created by the water overflowing the edge.

Discover how an overflow pool works

The overflow coping system offers complete integration between the interior and exterior of the swimming pool, harmonising the visual appearance of the space. Achieving this spectacular effect requires special ceramic pieces that are especially designed for this system. Besides playing a specific role in lining the pool and filtering the water, these systems are becoming an increasingly important feature in terms of aesthetics.

The Exagres catalogue includes a wide range of collections with all the special pieces required by overflow pools, including the ceramic grid and overflow coping pieces, as well as various finish options, such as stone, marble or cement.

But… how does an overflow pool work?

Operation

In an overflow pool, the water is constantly overflowing the edge to achieve an optical effect in which the surface of the water blends with the horizon. For that reason, it is essential for the water in the pool to always remain in the same condition. Unlike skimmer pools, in which the water bounces of the sides, an overflow system keeps the water in constant motion: the overflowing water passes into the channel that surrounds the pool through a ceramic grid; this water moves on to the balance tank and then the filter to be later returned to the pool after filtration.

The various construction options for overflow pools include the infinity and lake effect varieties, genuine visual spectacles in terms of aesthetics and constructive design

The infinity and lake effect pool varieties are the most common in the overflow system. The pool coping, which sits below the water level, is an essential part of their construction and enables the water to constantly overflow. The most important component of lake effect pools the ceramic grid through which the water enters the channel and filter system directly.

Filter system

Overflow pools are the cleanest. Any leaf or dirt that falls into the water will disappear over the edge, preventing it from reaching the bottom to accumulate or decompose. Due to their characteristic filter system, the water is constantly being renewed over a short period of time. This means that the water is always kept clean and crystal clear.
