Installing a Submersible Pump & Testing the Waterfall

The pump used in this video is a Water Rebirth pond pump rated at 9000 gallons per hour (GPH) (amzn.to/3C6JcPR). Pond pumps are high volume low pressure pumps as opposed to well pumps or cistern pumps which are high pressure low volume pumps. Just mentioning that so you know to use a pond pump for your pond or waterfall project.
So why a waterfall on this particular building project? Anywhere you build a house you're going to need to be familiar with the annual weather patterns and in some cases change the building plans accordingly. In Valle de Bravo, the rainy season is particularly powerful and potentially damaging to a house. With that in mind, I designed a method to capture most of the rain water that falls on the roof and the patios of the house and literally funnel it to the river. This design incorporated a stone waterfall which protects the steep terrain from the significant erosion that would otherwise occur. And as long as there's a waterfall it might as well be adapted to use as a water feature in the dry season. That adaptation is accomplished by adding a pond at the bottom with a submersible pump system to activate the waterfall as desired.

This was one of the best I have seen that was a real deal dude, so proud of you stranger

I smile ...... "the waterfall that was leaked," ........ and I'm concerned. Deb saw that waterfall and told me that she will be moving down there. That is really impressive - the concept, the design, the labor intensive construction. Beautiful. Thank you, thank you, thank you for sharing. Really enjoyable.

Very nice job. I am looking to do one very similar. What is the lift in feet you are placing on the pump you used? I am wanting to do a 9000gph pump and doing a lift of about 21 feet with 2 , 45 degree bends.
Thank you!

Hi Bryan, the lift on that is 13 feet and the pipe run is about 18 with two 90s and two 45s. I figured the end gph to be about half, so around 4500. I like it quite a lot but next year I may switch to the 12000 gph and see what that looks like. Apparently you can use a variable speed switch on those, or so I read.

Great stuff , I'm looking at building a similar construction in Uganda, I'd love you to share more on how you deal with the rainwater off your roof? I'd be having a flat concrete roof, and am wondering whats the best way to deal with it.

[@buildinginmexico]

I'd put a very slight slant to the roof - you don't need much - to direct the water where you want it. The roof on this building project we're currently doing will have a fairly gradual slope with a concrete and rebar damn on the bottom edge of the roof to direct the water to both ends where there will be 8 inch pipes to carry the water down and away, wherever that is.
