DETAILS ON HOW TO BUILT A INTERIOR WATER WALL ABOUT 12' HIGH AND
10'WIDE THE WATER WOULD RUN DOWN OVER A SMOOTH(almost vertical) ROCK
SURFACE INTO A holding tank then returned to the top of the water
wall.Need pump size, size of pipe and what size holes in the pipe at
top of wall to dispense the water evenly

Hi watewallman,

If my findings are satisfactory, please let me know and I will post
this information as the official answer to your question.


I found information at: DoItYourself.com Community Forums - building a water wall 
http://forum.doityourself.com/showthread.php?t=164246

"if when you say a water wall you really want a weeping wall, this
would give the effect of a wall that is always wet, i have seen this
done with several mediums. you can get expensive pre fab walls or make
one yourself with tiles. the easiest way to get the effect is to get
the smallest tubing you can, probably 1/4" would be best, next drill
holes that are slightly larger than the tubing and slide the tubing
into the hole so that it is snug and the water will go on front of the
wall and not leak behind it. all of these tubes can be connected
together with T-connectors and fed to a pump at the bottom of the wall
where you will need to build a small reservoir to hold the water. this
can be built from wood with a rubber liner or welded from steel."

"We built a wall of water for a client with very good results using a
1 3/4 HP shallow well pump to deliver the water to a 1" copper pipe,
about 20' vertically above the pump, 5' long, drilled with 1/8" holes
spaced 1" apart. The ironic thing was that the water flowed better
from the holes at the opposite end of the pipe from where the supply
was delivered. You would think the flow would be greatest at the end
where the water was delivered, but that's just not the case. Next
time, I wouldn't pressurize the water coming into the overhead pipe,
or source of the fall. I'm going to experiment with a 1" copper pipe,
cut open horizontally to allow the water to simply spill/flow over the
edge of the cut with the rest of the interior volume of the pipe
acting as a reservoir."

Best regards,

no I am not looking for a weeping wall it is a true water wall inside
a new home.It is for aesthetics only, I will indeed  be using a drak
gray slate I'm not sure how to put the lights behind the water feature
I was going to connect the slate to the wall,which would be
waterproofed due it beginning an interior wall.It seems using the
center of the outlet pipe would work fine, when it is said that a
small pump would work wuoldn't the needed volume of water over the
10'w X 10'h have a bearing

Hi Waterwallman,

As per Tlspiegel's info above, it looks like you will need only a
small pump to achieve the head height of 12'. Volume spread might be
achieved by pumping to the centre of the outlet pipe, not just at one
end.

Is your application for aesthetics, or is it for a commercial
application inside say a paint spray booth? Friends of mine have built
both. If for airbourne spray retrieval of toxins, coupled with fans
for air circulation there are cheaper methods than using rock.
Corrugated iron will suffice.

If for show, dark grey slate looks fantastic. Broken overlapping
sections with gaps turn the wall to magic when you place lighting
behind the wall. A large mirror on the opposing wall will double the
impact and provide depth to the room.

I sell industrial pumps, but for home or commercial use, I would buy a
Little Giant pump- they are cheap and readily available all over the
web.  A lot of people use them for pond pumps.  Just look for a small
submersible pump with a 110V cord.
