BWK pond build

[BruceP]

Anne... having it slightly recessed will make the flow smoother once the poly is sprayed. Otherwise you would have the slight lip of the bd. Better transition this way.

[Norm Walsh]

You make a good point Bruce.

When the Polyurea is sprayed around the BD pipe, a stainless steel clamp is used to secure the Polyurea to the pipe, then another layer is sprayed over that in order to make the seal. If there were no recess you would end up with a large lip in front of the drain.

When finished the transition from pond floor to BD will be smooth

Ahhhh...I didn't know about the hose clamp, makes perfect sense now.

So you are not using a 'typical' sump type BD, just a 4''(?) pipe??

Correct, just the 4" pipe with a aereted concrete lid

I've got the identical plan... can't wait to see how yours comes out! Do
you have any specific plans or pics of the lid? I was envisioning doing mine
in a sort of exposed aggregate with diffuser on top...

Here's a picture of the BD cover, this one is made by Sac. Koi for their Advantage System. It's about 15" in dia. with a 9" air diffusser

The pond floor got poured today, it's hard to see in the pictures but there is about 6" of fall from the outside to the BD

Interesting dome..I thought you said it was concrete...looks to be plastic, maybe you fill the underside with concrete?
Is the small pipe on the perimeter the air inlet?

[jackrent]

more photos !! that is really cool my next house is going to be post and beam with a 1000 gallons reef tank and a HUGE koi pond !

[Norm Walsh]

The lid is concrete Steve at Sac. Koi did a nice job with his mold, and correct the air inlet is on the perimeter

Man this is one awsome pond, please keep the pictures coming. When I grow up I want a pond just like that. Only problem is my wife says Ill never grow up

Growing old is mandatory.......Growing up is optional

Things have been moving slowly, but we're making progress. Had to wait on some of the exterior light componants along with the engineering on the window glass.

Pic 1: Some of the lights and return lines.

Pic 2: This light will point up into the sheer decent waterfall.

Pic 3: One of the two skimmers that are installed, I plumbed the overflow
lines into the sides of the skimmers.

Pic 4: TRP from Kent Wallace(Living Water Solutions) installed. BTW the
skimmers were supplied by Kent as well.

Pic 5: One of the four embedments that will be in the pond walls. These will
have steel beams attached to them to suport the concrete deck that
will surround the pond.

Pic 6: Shows the recess in the concrete around the BD and the airline, after
the Polyurea is clamped to the pipe, the recess will be filled with
material.

What is the outlet/inlet pipe opening under the skimmer? Will that be plugged?

That opening is plugged off, you would most likely use it if you were building a pool. Kent has modified the skimmers to have a 3" drainline.

[Norm Walsh]

Pic 1: Gives a wider view of the interior, the hole in the plywood will also be
the approx. location of the window.


Pic 2: Because the pond is mostly above ground we had to make sure there
were no leaks in the pipe joints that will be encased in the concrete so
every thing is getting pressure tested with air.

No earthquakes!
Man oh man, this is an impressive looking construction project.
Hey Danzcool....when this is done wanna take me for a spin in your GT to Santa Rosa?

.....Someday I'll learn to put the captions under the pictures

In order to have text between the pics, I think you have to upload the photos somewhere else on the web then paste the links for the pics into your text body here, rather than using the attachment function here.

Incredible build!!

Lee K. shows how to do it in this thread... but go to post #22. That's when
they added the "attach" option... works great!

That's gonna be one incredible pond!!

Thanks for the help Anne & Steve
