A perimeter pool, also known as a perimeter-overflow pool or vanishing edge pool, is a type of swimming pool where the water level is even with the surrounding deck, creating a seamless, visually appealing effect where the water appears to vanish.
Here's a more detailed explanation:
-
The Vanishing Edge Effect: The defining characteristic of a perimeter pool is that the water overflows the edges of the pool on all sides. This creates the illusion of a continuous, reflective surface that blends seamlessly with the surrounding landscape.
-
How it Works:
- The pool's water level is maintained right up to the edge of the pool's coping.
- As water spills over the edges, it flows into a hidden gutter or trough that runs around the entire perimeter of the pool.
- This collected water is then filtered, treated, and pumped back into the main pool, maintaining the water level and completing the cycle.
-
Key Components:
- Overflow Gutter: A crucial element that collects the overflowing water. It's typically concealed beneath the pool deck.
- Surge Tank (Optional): Sometimes incorporated to handle fluctuations in water volume due to bathers entering and exiting the pool, rainfall, or evaporation. This tank helps maintain a consistent water level and prevent the pump from running dry.
- Filtration and Circulation System: An essential system to filter, sanitize, and circulate the water from the gutter back into the pool, maintaining water quality.
-
Advantages:
- Aesthetic Appeal: Perimeter pools are visually stunning and create a luxurious and modern look.
- Noise Reduction: The constant overflow of water can help mask background noise.
- Effective Surface Cleaning: The overflowing water constantly removes surface debris and contaminants, improving water quality.
-
Disadvantages:
- Higher Construction Costs: Building a perimeter pool is generally more expensive than a traditional pool due to the added complexity of the overflow system and the need for precise engineering.
- Maintenance: The overflow gutter and filtration system require regular maintenance to ensure optimal performance.
- Potential for Heat Loss: The increased surface area exposed to air can lead to faster heat loss, potentially increasing heating costs in cooler climates.
In summary, a perimeter pool is a sophisticated pool design that utilizes a continuous overflow system to create a stunning visual effect where the water appears to vanish into the surrounding environment.
