AL's pool pond conversion

Post by AL on Mon Apr 25, 2011 12:47 am

I decided to convert my swimming pool to a koi pond a couple of years ago .

But due to illness only started construction in September last year, I will do this as a photo journal if ya have a question just ask.

Basic filtration drawing




Pond cleared of 4 000 kg of rock and boulder the biggest of which was about 3 foot x 2 foot




We removed the side fence for access from the lane way.



After day i digging we had removed about 18 cubic meters of soil.

Another shot of the hole from the top of the ramp for the machine.



Some very basic shoring was erected to hold back the soil before the plumbing was commenced.



I started with the bottom drain tunnel which extended underneath the pond by about 600mm or 2 foot



My worst nightmare climbing under the pond to clean the bottom to seal the bottom drains.



Bottom drain pre-plumbed I also cut the pipe to length so it could be pushed under the pond and into position.



Bottom drain holes ready for install at this point there was no turning back.



Bottom drain install with a little help for my favorite son



You can see the 2 BD pipes on the left with the BD air in the background I had back-filled the bd tunnel with stabilized sand and had also installed the Mid water pick up for the shower also.

Due to not having much room to fit everything I spent a little time creating some working drawings with lay out points so i could set up string lines to keep everything in the right place. This pic shows the sump which all the waste lines will run to the manifold you can see is for the static pre-filters for the settlement chambers.



This pic is of the layout for the drain for the settlement chamber.



After 3 days of digging like a mole i got all the plumbing pre-laid so we could compact and prepare for concrete.



Plastic membrane in with galv reinforcement ready for concrete.



After troweling it 5 times i have decided that doing concrete is better left to the pro's as i don`t like hand fulls of blisters.



Bricks in and ready for brick work the following weekend.



Outside brickwork finished ready for re-bar and the inside leaf the following day.



Vertical rebar in which was the tied horizontal also



Inside wall finished.

Mid water pick up in the foreground which is feeding my shower.

The FF on the shower are doing a good job i nearly have them right now they have taken a little tweaking.

The problem is with no BD circuit running i think i am getting a little more doc than i would be with it running and with the diffusers running at night i am getting bubbles on the surface in the morning. Twisted Evil

I am thinking of doing a low dose PP treatment to burn some exta off ?
