INSTALLATION
Recommended Site Layout
It is always preferable to draw feed water from a
Borehole or Beach Well. Drawing
water directly from the open ocean creates additional maintenance requirements, as
pipes, pumps and the filtration system are exposed to sea life. All of this is avoided by
using the local geology as a barrier to sea life. The feed water from a Borehole or
Beach Well will typically run quite clear after the system has been running for a few
days.
Feed water is moved and pressurized by either a
Jet Pump or a Well Pump depend-
ing on site specific conditions. If the system cannot be installed close to the feed water
source, the Jet Pumps provided with the system can be relocated closer to the water
source. Jet Pumps are more efficient when placed close to the feed water source and
will self-prime up to 10ft. (3m). The pipe runs for each of the two systems should be at
least 1-1/2” up to 50 ft. (15m) and be increased to 2” (or more) f it needs to be longer.
Please consult our application engineers to select the correct pump and pipe diame-
ters for your installation.
If the feed water has high turbidity (cloudy water) a
Settling Tank may be a good addi-
tion to the installation. A Settling tank is also useful if the feed water intake varies due
to tides or other site specific constraints.
The input and output connections to the
Container are outlined on the next page.
The Product Water Tank should ideally be sized to so there is enough storage to sup-
ply water for at least 24 hours to allow for service and maintenance. Water going to
the product tank will be chlorinated by the chlorine injection system in the Container.
The
Potable Water Delivery System (by others) needs to provide pressurized water
20-50 psi (1.5 to 3.5 bar) to the Fresh Water Flush Connection on the container.
