Find out the 5 typolgies of overflow

It is impossible not to be amazed in front of an infinity pool. You immediately want to get closer, touch the water, contemplate it or maybe even dive in.

Infinity pools are built with very high technological standards and often offer wonderful scenic effects.

But what exactly is an infinity pool?

As the word itself suggests, in an overflow pool the water touches the edge of the pool and gently pours along the walls, ending up in a channel located on one side of the pool or along the entire perimeter. Unlike the skimmer pool, in which the water recirculation takes place through the skimmers (outlets positioned on one of the walls), the filtration of water in an overflow pool is much more efficient in terms of maintaining the quality of the water which is always somewhat crystalline.

Furthermore, from an aesthetic point of view, the infinity pool has a much more elegant and prestigious appearance. Since the water level in the infinity pools reaches the top of the pool, all the space that goes from the water surface to the upper edge of the pool is eliminated, with a much better aesthetic result.

The unquestionable technological and aesthetic superiority of this type of swimming pool logically increases its costs, but as we have said several times, an infinity pool offers so many advantages that it can be considered without a shadow of a doubt The Swimming Pool par excellence.

 

THE VARIOUS TYPES OF OVERFLOW

The vast majority of people think that when we talk about an overflow pool we are talking about the pool with a panoramic effect, also called an infinity pool. However, this is a big misunderstanding since an overflow pool can be built in various ways and with different types of water overflows.

There are five different categories of overflow and in this article we will explain them one by one.

 

PANORAMIC OR INFINITY EDGE

The infinity pool is the ideal solution for those who love the visual continuity between sea and sky or between earth and sky. The water level reaches the limit of the wall and then falls by gravity into a compensation tank thus creating a spectacular cascade effect. The water can alternatively fall in a choreographed way into a smaller tank set at a lower level than the main one. We also remind you that the infinity overflow can be made on two consecutive sides of the pool.

  

  

 

FLUSH OR ZERO EDGE

In flush or zero edge pools, the water reaches the limit of the wall, flushes with the edge beyond, before falling by gravity into a slot and reaching the overflow tank. Considering the absence of overflow channels, the visual effect is clean and modern. It is also possible to customize the edge by choosing different materials for its building.

  

 

UNDERFLOW OR HIDDEN FLOW

The underflow swimming pool has revolutionized the concept of water overflowing. The pool’s water overflows under the pool’s edge, along the perimeter, hiding the overflow channel, thus achieving a clean and aesthetic final result.

Thanks to this technology it’s possible to easily adjust the level of the overflow that may eventually undergo some changes due to the settling of the ground or geological events.

  

 

TRADITIONAL OVERFLOW

The traditional overflow pool is made with a whole perimeter overflow channel. The water comes flush with the outside pavement overflowing in a classical duct or into splits directly cut in the floor or at the edge.

  

 

RAISED OVERFLOW

In the raised overflow pool, the water flows out of edge into a channel  placed at a lower level than the surface of the pool, forming in some cases a real cascade effect, and in others a simple wall of water flowing elegantly on the edge of the pool.

This is in fact a special type of flush edge overflow, with the difference that the edge of the pool is raised along the entire perimeter or along one or more sides.

The particular design of this type of swimming pool easily adapts also to wavy, steep terrains with the cascading sides placed in sloping areas.

  

 

ADVANTAGES OF THE INFINITY POOLS

We have already talked about this topic and if you want to learn more you can consult our article on “The 7 advantages of Overflow Pools vs Skimmer Pools”.

Building an overflow pool involves an important economic effort: on the other hand we are talking about an asset that not only increases the prestige and value of the house, but that will last forever and will be used in the years to come by friends, relatives, children. and grandchildren (we have many clients who have given us testimony of this).

Making an investment means facing the expense wisely, with a keen eye on the long term as well as on your own aesthetic tastes. After all, it is an element intended for well-being and an increase in our quality of life.

 

RELY ON TRUE POOL PROFESSIONALS

Like all beautiful and quality things, even with regard to overflow pools there is a "weak point": the execution of the works. Not surprisingly, after over 30 years of experience in the sector and having created swimming pools of all types, shapes and sizes, we have decided in recent years to dedicate ourselves exclusively to the construction of overflow pools.

In fact, building an overflow pool requires much more mastery, knowledge and experience than normal skimmer pools. It is therefore VITAL to rely on a serious, professional, specialized company able to follow the customer at 360 degrees, from consultancy to construction site work, from the implementation of current regulations to technical projects.

After all, this is YOUR pool. Request high executive standards and first-rate professionals.
