some questions on designing pondless feature

I'm bidding on a back yard feature with a drop of about 7 feet. It will be 35' to 40' long and end to a basin which will be incorporated into a 23' radius pave stone patio with fire pit.

I figured I would make it meander through 2 or 3 curves and have 7 to 10 falls, maybe a few falls with more than one cascade.

Should I have less falls with a greater drop? Or would 8 to 10'' per fall give the sound effect that we want to create? I want it to be heard from the upper patio 30' away from the start of the falls (70' away from the basin and last fall).

Also, how many GPM should I use on a feature of this size? and how wide should I plan to make it? I was thinking 3' wide or so?

Thanks for looking and I appreciate any advice for my design.

I'm going to do some image editing with pro landscape eventually for this project, and I will post the proposed look after I'm done.

30 people look, but no one says a word?

These aren't stupid questions are they?

Just from your measurements of your stream, you are already at roughly 15' of head pressure not including your fittings. So at 3' wide of your falls your pump size is gona be least 10000 gph of water going over your falls to give your achieved sound give or take a little. Make sure you use a 3" line or 2 2" lines with two separate pumps.

You will need at least 10,000 gph, prolly more to get the effect that you want. The primary/source waterfall should be 3 - 4 feet wide and incorporate a drop of 2 - 3 feet. This must be your focal point both visually and acoustically. Incorporate a catch basin at the base of the primary falls to control splash and create the desired sound. Vary the width and depth of the stream to create interest and maybe even include a couple of step pools.

Pics would help as would a present site plan.

A feature of this size footprint can incorporate so, so many interesting mini-features.

Two pumps would be OK, but not really needed IMO unless you want to build some redundancy into the feature. This IS a good idea, if budget permits.

Post more info; get more info!!

On this build I used an Anjon Bigfrog 5500 pump. The width is close to what you want, but I'm not sure it will produce the sound your wanting.

Another thing to look at is most 10K pumps will average $90-$100 a month to run. He He I couldn't resist when I found this vacation pic.

Andy should use the first photo as a design template. Something like that would definitely please his client. They would, for sure, get more 'splash for the cash'. I would love to tackle a project like that!

When you say catch basin at the beginning, do you mean just a deeper and wider area than the rest of the stream?

I'm loading site plan number 1.
I'm sure it will change.
Right now I'm just in the process of figuring materials and spitting the client a price.

I have a picture on my camera that I will post as soon as I restart the computer. Its not working right at the moment.
