Infinity edge pools are swimming or reflecting pools that produce the effect of water extending to the horizon. They are also called zero edge or negative edge pools. In locations where the edge of the pool appears to merge with a larger body of water like an ocean, or with the sky, the effect of an infinity edge pool is extremely impressive.
Some of the most stunning pools ever built are infinity pools with a lake, bay or garden beyond. Enabling water to disappear over the edges of pool walls is unmistakably inspiring.
Design
Designing an infinity swimming pool is a highly specialized undertaking that takes planning, engineering and exacting science to properly create. Every circumstance must be considered before actual construction begins. Extensive structural, mechanical (hydraulic engineering) and architectural detailing is required. The structural engineering must be based on the geological conditions of the site.
The high cost of an infinity pool is often due to the foundation system that anchors it into a hillside.
How an Infinity Pool Works
The edge of an infinity pool ends at a weir that is lower than the required pool water level. A weir is a small dam that pools water behind it while also allowing the water to flow steadily over its top. The water spills into a trough or catch basin that is constructed below the weir and from there it is pumped back into the pool.
Advantages of an Infinity Pool
An infinity pool doesn’t have visible edges and so blends in with the surrounding landscape. This offers swimmers an unhindered view of what lies beyond the pool. It also provides better water circulation than a regular swimming pool.
Is an Infinity Pool right For You?
While an infinity pool would be an exciting addition to any property, it may work better for some homeowners than others. If you have a naturally sloping backyard and a more scenic view, you will find that an infinity pool will fit naturally into the surroundings. Such a pool reflects what’s around it so you’ll want a well-landscaped lot and stunning views to increase the effect.
Infinity pools are more expensive than regular pools because of the work required to design and build them. They are also prone to lose heat faster when they’re operating, because of the greater water surface area.
Maintenance
Typically, infinity pools require less overall maintenance and cleaning than regular inground swimming pools because the waterfall system is continually moving the water around. The greater flow within the pool provides an instant filtration system.
This water flow makes for less general cleaning of the pool itself, including clearing debris and scrubbing surfaces. However, leaves and other debris will end up in the catch basin so this area will need to be checked regularly and any debris removed so that the water flow remains unhindered.
Be sure to choose a pool builder with extensive knowledge and experience in building infinity pools and one that has in-house engineering and design departments.
