Zero Overflow Edge
perimeter overflow
So coming back to the spa overflow edge, we see very similar characteristics to the water feature I just showed or I showed above. And this is also a beautiful feature water feature for your backyard. If you want any consultation on building a zero edge pool or spa, and if you want to know how to design it, how to construct it, any of those details, how to estimate the size of a surge tank, contact me and I can give you some options to either do it yourself, to guide you through the process or I can do all the calculations for you. I can do design work, but I also have a designer that I can recommend if you want an award-winning designed infinity pool or and zero edge overflow pools.
The first photograph is of a zero edge spa. It overflows into the pool and it is called a zero edge overflow because water flows over all of the edges. Keep in mind that when the spa is heated, then the overflow stops and the water just recirculates from the spa back to the spa. And so all of the heated water is retained in the spa. However, whenever it is not in spa mode and the pump is running, then it becomes a feature, a water feature, and it flows over the spa edge or edges into the pool.
The next image down, or series of photos are of, again, another example of the same idea. But these vessels overflow, not only do they overflow into each other to some extent, but they also overflow the edges. And looking at the photograph, it is quite a baffling situation. When water is seen to overflow the pool, and the question arises as to where does the water go? And part of the beauty of these zero edge pools and spas is that the water seems to flow over the edges in some sort of a magical way. It’s completely inexplicable when looking at these zero edge pools and also the spa.
And here is a key factor, is that around the entire vessel, if it’s not flowing into a pool such as this one, it will flow into a concealed trough that is concealed underneath a grate. Generally, the grate will be fiberglass or stainless steel, and on top of the grate will be either some sort of gravel or something decorative.
So speaking about how this is built, I will explain that this is a very complex series of pools that not only flow into each other to some extent, but also flow over their edges.
And so in building something like this as a builder, if you are a builder, you will not want to second guess how this is built. It does require advanced understanding of fluid dynamics, and of course how the system should be plumped. And I will give you some answers. So if we look at each one of these vessels, we see that water flows over the edges. Now, if for example, the water flowed seriously from the top pool into the adjoining pool and so on and so forth down to the end pool, then this would’ve drained itself. So it really gives us the illusion that it’s doing that, but that’s not the way it is plumbed.
So let me speak about the plumbing to try and create something like this. What happens with the plumbing is that each vessel has a line that goes to each vessel. So there’s a return line in each vessel, and the return is coming in through a very cleverly concealed return that we can see with a slot allowing just enough water through to ripple over the edges.
Now, knowing that each one has its own dedicated return line means that there is a surge tank somewhere in this vicinity where water is sucked out of the surge tank via a pump or a series of pumps, and then water is returned back to each vessel. Now, that can be done with one dedicated pump to one vessel. So in other words, each one would have a suction line from a surge tank and going back to each vessel. So we could count 1, 2, 3, 4, at least five pumps to run this successfully. It cannot run on one or two pumps that basically suck water from a surge tank and return the water back to the top because it would never have this consistent amount of flow. So while these are complex, they’re very difficult to build. They are extremely rewarding, and they really create such a serene effect and style either for your backyard or even a fountain feature for your front yard or your business.
So coming back to the spa overflow edge, we see very similar characteristics to the water feature I just showed or I showed above. And this is also a beautiful feature water feature for your backyard.
