Step 3 -  Installing the pond.
This is the most time consuming step in the process. Start by digging a hole to the exact shape adding two inches to the depth to accommodate a layer of sand. Clear the hole of rocks and other debris, smooth the soil and level the top edges. Once the shell is in place, fill the pond slowly. Backfill with soil as the water level rises to ensure that the shell walls are adequately supported by soil. Trim away the surplus liner and bury the edge with excess soil , stones, bricks or other paving material. Fill with water and dechlorinate when using treated water.
