• Now install the barb fitting included with the kit into the
bulkhead fitting. A PVC slip fitting has also been included
in case you are using flexible PVC pipe. Use some of the
silicone sealant included in your kit to coat the threads of
the fitting, providing a watertight seal (Ex. 8).

• Now it's time to position the BioFalls in the desired
location.
• The BioFalls should be set at or slightly below the grade of
the yard. Simply remove a section of sod or a few inches
of soil in order to create a firm foundation for the BioFalls
to sit.
TIP: Keep the waterfall to the scale of the yard!
The goal should be to create the perception
that Mother Nature herself has constructed the
waterfall. Avoid creating a "volcanic look" by
trying to raise the BioFalls in a flat backyard.
• Be sure to compact the area beneath the BioFalls using
a hand tamper or some other heavy flat object that can
be pounded onto the soil. This will help prevent any future
settling.
• Use a 2' bubble level to make sure your BioFalls is properly
set into position. Your BioFalls should be level from side-
to-side and tilted forward 1/4 of a bubble on a 2' level.
This will make sure the water comes over the front of the
BioFalls and covers the entire spillway (Ex. 9).

• The filter is now ready
for the kink-free pipe and
hose clamp to be slipped
onto the barb fitting. Have
someone hold the BioFalls
in place in order to prevent
it from shifting. In some
instances the tubing/hose
may be tight and difficult to
Ex. 7
use with hose fitting barbs.
If this is the case, we recommend heating the hose with
the use of a hair dryer or simply dipping the hose for a few
seconds in very hot water. Lubrication can also be used;
we recommend silicone grease or vegetable oil. Once
installed, the hose clamp can be tightened to secure the
pipe on the fitting (Ex. 10).
• Double check to make sure the BioFalls is still level after
installing the plumbing.
STEP 5
EXCAVATING YOUR POND BASIN
• We suggest excavating the pond no more than 18-24"
Ex. 8
deep. This depth provides the proper water levels required
for aquatic plants and is deep enough to keep fish alive
during winter.
• The excavation should be
dug with a series of shelves.
The shelves will add stability
to the walls of the pond
and will also create planting
beds for different types of
aquatic plants.
• The first shelf should be
about 8-10" deep, or the
height of a standard shovel
blade (Ex. 11).
• Dig the second shelf
another 8-10" deeper
(Ex. 12).
• The third shelf (if desired)
will be excavated down
another 6" reaching a final
excavation of 24" (Ex. 13).
• All of the soil removed
from the excavation can
be spread and compacted
around the BioFalls,
creating a berm. The filter
should be completely
surrounded by soil by the
end of the project. Be sure
to verify that the BioFalls
remains level throughout
the process (Ex. 14).
