Default Poolside Waterfalls

Just got finished having our in-groud pool installed so now it's time to start with the Waterfall. As I intend on making this the focal point of the pool, I am looking for some ideas of what you may have. I have purchased 1 pallet of Flag Stone and custom built my own "spill way" out of Stainless Steel being that my pool is saltwater. If you have a poolisde waterfall and would not mind sharing some pictures with me so I can get additioanl ideas, I would appreciate it...

Thanks

Here is our pool at our rental units. It is pretty simple, we have a separate pump for the pool and the waterfalls. We also put valves in so we can restrict the water going through the waterfalls and the fountain. The nice thing about the water falls is the sound, there is something about falling water. With what you are thinking maybe you would be better off looking at pictures of ponds.

Here is an old link of some of our members ponds, including mine, one thing I learned was I way, way under estimated the amount of flagstone I needed. I scored all mine with a chisel and fit each piece tight together, but I did use allot more flagstone doing this, but I was happy with the results.

There is all kinds of rules to apply, but I go by 300 gph per foot of width. This will give you approx. 1/4" thick worth of water @ 1' wide. Now that is not what I call a nice volume of water for a full body water fall. I like numbers between 500 and 600 gph per foot width of water falls.

Now those numbers are all great, fine and dandy, but they do not take into account of how high the water fall is and how long the hoses need to be to take water from point A to point B. Additional gph will be needed to adjust for these numbers.

A few things I should point out to you is:
- water will evaporate quicker with a water falls running constantly.
- if it's windy out, will the wind blow your slashing water out of the pool?
- if the water slashes on to concrete or stone it will evaporate the water instead of returning it to the pool.

My Waterfall will run off of the same pump that supplies the pool. I have a seperate 1 1/2 " line that was installed 22: off of the corner just for this application. As mentioned, I custom build my Spillway 22" W X 18" D X 16"L 10 GA with a 18" W X 22" L Spout. I plan on cutting each piece of Flagstone to gain an overall height of 48" Tall but I am unsure about the overall width. I would like to have a "step effect" in the waterfall with water faling from one level to another level and then finally into the water...

I plan on posting this "build" here on THT so everyone can hopefully enjoy and get some ideas if they ever wish to have one built

So, what's your pump putting out? ....all the rest doesn't matter until you know what your pump is pumpin gout.

That really sounds nice, i am curious to see the finished product. One thing about using one pump, is if you do have a leak in the falls, and when you add flagstone to the mix, you will lose water, your pool level will go down to either the skimmer level or the worst case scenario the bottom drain. Garrett hopefully will chime in on this but that is one reason to keep the two separate. How are you going to hide the stainless? Also I believe the hardest part is trying to keep it natural looking without looking like a big water-slide in the middle of nowhere. It is allot easier on a pond scenario as you can hide lots with landscaping.

The Stainless will be hidden within "inside" of the flagstone and the only part that should be visiable will be the 2" opening that will be used as the overflow. Each level of water will be contained to prevent spillage or splashing so water loss should be minnimal with the exception of the typical evaporation.

We use one pump with a diverter valve. We can change the waterfall flow and turn off if necessary.

Ours is in the corner and fed by a 1 1/2" pipe. 2: feeds from the pool and 1 1/2" returns with 2 hp pump and oversize sand filter. I don't have any pictures, but mine sits in the corner and is made of 2" thick stones stacked. maybe 2' high in the back and dropping down to a single stone at the pool. its about 4' wide. on the sides I have plantings and then pavers to complete.

This is the only picture I readily had that gives you an idea.

BACKTOTHESEA

That's the same plumbing that I have as well as the same build process that I am thinking of with the exception of mine being a little higher in the back then gradually falling towards the pool.

You have a very nice set up....

Absolutely as Mike as has pointed out, one needs to design against leakage....therefore a rubber linner is needed or an insert or a custom welded SS tub/ pan. Will you be using a resevior up top or direct flow?

A seperate pump with shut off and flow control is good....are you doing one or more than one entry into the pool?

To quote you, "As mentioned, I custom build my Spillway 22" W X 18" D X 16"L 10 GA with a 18" W X 22" L Spout". Sorry but you numbers are confussing to me, can you please explain them. How wide do you want your water fall to be? Will you only have one water fall?

Do you have any idea how much water you are going to get out of a 3,600 gph pump?
Do you know what the watts per hour are on that pump you'd like to run? Would you consider buying another pump?

We had this installed at the time we had the pool done. It has turned out to be a nice feature to have, I was unsure at the time we did it.
