- 2 to 2 1/2 feet deep. Not a vertical excavation and not shelved excavation either.
- liner installation (Obviously!)

- The hole was dug. The perimeter around the top of the pond was lined with left over pavers from the patio to elevate the edge of the pond just slightly.
-Savio waterfall filter used for both mechanical and biological
-Small Sequence pump
-Intake from the pump is 2" PVC stubbed into the center of the pond, on top of the liner, with 1/4" holes drilled all over the place.
-If you look closely in the center of the photo just to the right of where the suction pipe from the pump enters the pond you will see a small circle of foam/bubbles. That is the floating skimmer that is tee'ed off the suction line that crosses the bottom of the pond
-Some unknown brand (to me) UV is plumbed in between the pump and the Savio waterfall filter. His friend or neighbor that know Koi Pond Construction installed it for him after the landscaper was gone.
-Aerator is plumbed to the far right of the pond.
-The slope behind the property is watered heavily and constantly sends water underneath the pond. Under the white tupperware lid is an 8" pipe installed vertically as a vault. It is connected to a small gravel pit that leads to the underside of the pond. When the pipe fills with water a sump pump with an on/off float device actuates and sends the excess water to the drain system which exhausts to the gutters in front of the home.
-Crushed stone gravel was scattered through out the UPPER edges of the pond.
-The straggling white pipe at the top of the picture was a loose pipe that the homeowner was instructed to use if he ever wanted to change water. All he has to do is unplumb the pump, reprime it and pump water onto the property behind him that inturn would run under his pond and then be pumped to his gutter in the front of his house from the vault under the white tupperware.
