In this video I'm going to show you how you should not build a water wall, how you should not do the water distribution and the overflow channel.

The first problem here, as you can see, is that the back wall is very low and the water can escape at the back too, if you produce here more waves. And then the second thing is that we just have a couple of metal plates with holes inside this overflow channel, inside the gutter. But the feeding comes from the middle. So, if this is the complete overflow channel we have a feeding from the middle and on that feeding there sits a small cap. So, this is this one and this cap causes the water only to escape into two directions, so we get a venturi effect which means that we produce a lot of pressure here due to the water which comes to the sides. But we have low pressure here in the middle and according to that, the water does not flow over the overflow channel here in this middle area, and...

So, when you build a water wall or an indoor waterfall then you want to use a water additive against germs and algae, but you should take care and be very careful to test the water additive, because it might happen that your water additive is changing the surface tension of the water and then you can have two effects, which are pretty bad.

One effect can be that  you will not be able to create a water film across the whole glass plate, like for example in this water wall. Here you can see we have a very nice complete water film covering the whole glass plate with harmonically distributed waves. So if you use the wrong water additive and increase the water tension of the water then you get such streams which then do not cover the complete glass plate and they're also pretty loud and they create splashing.

Then the opposite of that is if you have a water additive against algae and germs which is destroying the tension, the...

I found this pretty loud Indoor Water Wall in a Hotel - it is impressive, but a little damaged. (This waterwall was not build by us.)

In this video I'm going to show you how we have planned a water feature in the backyard for a customer.

Here you can see the basic set up, already with all the covers but just up front, down here, we have a tank. Here we would have the pump. The pump would direct the water through a 32 millimeters diameter hose or pipe to the top of the water wall and then the water would be distributed in an overflow channel, which I will show you in a minute, and then the water would go across those natural stone tiles, being collected here in a bottom tank and then moving forward back to the tank, which is digged below the grass. So, this is the main circle.

Then you can see here an overflow channel made of stainless steel which is supported by 2 PVC sub distributions. So, this 32 diameter pipe is then divided into two pipes and each would have a PVC sub distribution. This sub distribution is very clearly explained in our Glass Waterwall...

I want to thank Ameen who has sent me this video of the water wall he has built and here's a challenge : actually it is working, not bad, as you can see here, so he has a complete cover of the surface, but he contacted me because he said it's not possible to let the water run down slowly.

So this is because if you use such a pipe with holes then the water does not have the possibility to unite, so you have those different streams. In an other video a few weeks ago I have shown you this water wall which I have found in a pharmacy and it's a very beautiful water wall, by the way, so the stainless steel work is really like an art. But the water distribution also was made with holes in a pipe. And as you can see here too, you when the holes get polluted then the water will run down the pipes. This is one problem or one reason why I don't like such pipes but the other reason and this is what the problem Ameen has right now, is that you...

In this video I want to show you our test, which we have made, with natural tile stones in order to create a water wall. So the customer asked us to plan a water wall and so we did what we always do and what we really recommend, we tested those natural stone tiles before we did the planning and the installation. And there are actually the two most important things are here splashing and free falling drops and the color of the stone.

Let's just begin with splashing. So we have tested the water distribution with different amounts of water, well, it's not precise but it's just a volume of water which we have driven across the surface and you can see here at 25 percent, well, it's barely covering the whole thing. Then we opened the pump a little bit and, I think, this has been the best setting with 50%. 75% creates too much streams and I would say it's too much and 100 percent is far too much.

So, okay, so we have found out that the...

In this video I'm going to show you the three big problems you might face when you use a pipe with holes like here in order to get water distributed at a water wall or at the indoor waterfall. I'm gonna use this example because, actually it's pretty sad, because this is a real good craftmens work, actually it's really an artistic design and it's high-quality stainless steel work here, but the sad thing is that the guy who has built it probably never has build a water wall before because otherwise he would have used another water distribution system.

So three problems will occur when you use a system like this: The first one you can see it here: you don't get a complete water distribution as you can see we have here at the left and at the right side dry zones. This is because of the water distribution and because of the borders here. So, that's going to get ugly, because you might imagine that this is actually not looking good if...

In this video, I want to show you the overflow channel or you can also call it spillway or gutter, I use to produce water walls. Actually this system I have used probably more than 150 times, and from my opinion, it's the best one because you can make a very good water distribution so that your surface, where you run the water over, is going to be floated completely. Because this is actually the biggest challenge to get a water film which will cover the whole plate. You can use a glass plate or you can use a stone plate or a stainless steel plate but it's always the most important thing is to get the water harmonically distributed on that surface. For that reason, I'm using this so called overflow channel and I'm going to show you also a couple of videos about this overflow channel in real life. But let's start with this construction drawing so that I can explain you the main elements of it.

So first of all, it was until today,...
