Overflow Pools, Benefits & Challenges:

The majority of top aquatic facilities now include two or four-sided ‘overflow pool’ or ‘wet deck’ design. What is now standard in pools across the world has its origins in the swimming events of the March 1972 Munich Olympic Games. Australian market leader Anti Wave takes a look at the characteristics, its benefits and challenges.

Benefits of Overflow Pools

When compared to traditional-type non-overflow or ‘skimmer’ pools, overflow pools provide a more professional, aesthetically pleasing pool deck environment, allowing higher filtration rates and enhanced water filtration.

With an overflow pool deck, the entry is at water level, while the water is directed across the pool surface and over into the overflow gratings and channels, which minimizes the turbulence.

For competition swimming facilities this leads to minimal turbulence caused by swimmers returning back into the Swim lanes. Non-overflow pools are not as effective at turbulence dispersal, as the waves are reflected into the pool walls, causing refracting turbulence.

Overflow pools provide a more professional pool experience for swimmers and provide a faster pool for competition and training.

Overflow Pool Challenges

The ability of swimmers to execute successful flip turns can be affected due to the lack of raised wall sections at the turning point. Injuries have been known to occur due to swimmers feet.

Overflow Pools are by design a ‘wet deck’ pool environment. Coaches and staff who are in nearest proximity to the swimmers can receive large splashes of water by each turning swimmer.

The overflow pool design also require the installation of End Walls or Block Stands in order to raise the blocks to the required regulation height, over the overflow grating channels.

Anti Wave Overflow Pool Solutions:

To meet the demands of the overflow pool, Anti Wave has a range of innovative performance solutions available in their product range.

1. Overflow Pool Gratings

Anti Wave can supply a range of overflow pool gratings with two main varieties – Transgrate or LongiGrate.

TransGrate is recommended where curves are present that require a straight or curved installation.

LongiGrate are installed in straight edged pools, where a higher level of structural support is required over the gratings channel, such as where deck equipment is to be placed over the gratings.
