Although I live near an urban area, with city utilities available, as a social and
environmental statement I choose to live "off the grid" with solar
power and recycled waste. I process my blackwater with Sun-Mar's
Centrex 2000 NE composting toilet system. I started with another
manufacturer's product, but it failed within a few months. I have
enjoyed my Sun-Mar system for 5 years now. I appreciate its simplicity
and reliability. I am able to process waste from 3 low-flush toilets
that feed the biodrum which is located in a walk-in space under the
house. The staff at Sun-Mar has been extremely knowledgeable and
helpful. When small problems arise they offer expert advice at no
charge and supplies at a reasonable fee. In fact, I am so pleased with
Sun-Mar's products and service that when I built a guest cottage, I
installed a Sun-Mar Excel NE whose performance is flawless. Thank you
so much for your fine products, friendly service, and longstanding
dedication to living in harmony with Mother Earth.

Location: Installed in 10 houses in the Bahamas

I am an architect/developer on an island in the Far Bahamas.
We have built a small eco community – 10 houses 22 Sunmar
Centrex 2000 NE units.
In our community, most of the houses are within 50 feet of the
beach and the waters are always turquoise, composting toilets were
an obvious first element. Having had a practice in Sweden for 20
years, I was very familiar with the many versions of off the grid
toilets that exist in Scandanavia, from electric incinerator toilets,
numerous variations of composting toilets and even freezer toilets.
I was therefore very critical when it came to choosing a composting
system for our climate and building type in the Bahamas.
Our buildings are built on pilings from two to three feet over
ground level. The main reason that I initially chose Sunmar is because
the Centrex units were the lowest that I could find. This was important
because the floor height of the buildings was determined by the
The ladies were less interested in building floor heights. They
unanimously insisted on a low water flush toilet system. My Swedish
wife did not want to stare down a dark hole that she associated
with privies in Sweden. So we chose a rather exclusive solution
of a Centrex 1000 NE unit for each bathroom with a Sealand low flush
Over the 5 years of experience with these toilets, (ours are used
every day) I would like to say that there are certain inherent problems
with introducing too much water in a composting sytem. Cleaning
personnel have a tendency to want to wash down toilet bowls with
disinfectants and masses of water – inspite of instructions
to the contrary.
Too much water stops the composting process and one would expect
trouble from the smell from anaerobic decomposition.
I can’t figure out how Sunmar engineers have managed to create
a system that even in the worst flooded conditions DOES NOT SMELL.
I would like to add these conditions arise only due to improper
use of the system by overzealous cleaning personnel or guests who
are not attentive to the ECO in ecotourism.
And in the best of conditions, I never tire of showing off our
toilets, taking our many interested visitors directly to the “dirty”
end, opening up the composting drawer, grabbing a handful from the
drawer and thrusting a handful of composted material first under
my nose and then under theirs. They are always flabbergasted because
the resulting compost smells just like wood land loam.
I originally had some problems coming up with a proper mix for
filler. Lacking diggable soil, I was forced to import whatever materials
I would need. I first tried peat moss, much of which would fall
into the drain pan under the drum, thereby inhibiting proper drainage.
I now use a mixture of peat moss and kiln dried wood chips meant
for bedding in stables with great success.
