Toilet-Waterless Toilet-Composting Toilet

Eco
friendly

A sanitation system that does
not require any water to function. Not only does it save on water use, but
it is entirely isolated from the surrounding environment and cannot contaminate
underground water resources.

How can sanitation work
without water ?

The system utilises a natural biological process
to break down human waste into a dehydrated odourless compost-like material.

How does it work ?

We receive many questions
about the toilets, of which " How does
it work " is the most frequently asked

Toilet hut ( optional )

When a toilet is to be installed outside
a home, we can supply a toilet hut that has been designed especially
for the ECOSAN toilet system.

The toilet can however be installed using
any toilet hut structure.

The following is a brief description
of the ECOSAN toilet concept as well as it's main features.

The human excrement falls down
a vertical chute (2) and into one end of a specially designed helical
screw conveyor (3). Every time the toilet lid (1) is lifted, a mechanism
rotates the conveyor. With each rotation the human excrement slowly
moves along, taking approximately twenty five days before falling
into a reusable collection bag (4). It takes six months for the bag
to fill with dry and odourless waste. Through the uniquely designed
ventilation pipe (5), adequate airflow is provided for the dehydration
/ evaporation, deodorising process. Human excrement consists of roughly
95% moisture. As the solids dry in the conveyer the urine and moisture
is vented into the atmosphere. The solid waste then dries into a compost-like
material, roughly 5 - 10% of it's original mass. The dry waste is
manageable and can be processed in the following ways. Use it in the
making of compost Dispose of it by using municipal waste services
Use it as a source of fuel Large objects like beverage cans, disposable
nappies or other objects accidentally dropped down the chute will
not block the system, It is however not advisable to do this

No plumbing required

No drains

No pipes Waterfree

Low odour levels

Chemical free

Relatively light and easy to
install

Mining and other high volume usage
units. As a variation on the home model designed for normal use, a
special modification was made to accomodate installations where there
is a high frequency of use of toilets. This model uses a drum instead
of a bag for waste collection. The unit is therefore not a completely
dry system and also means that the drum needs to be emptied on a regular
basis. This unit is ideally suited for places where the installation
of sewerage pipes are difficult, for instance underground mines or
very busy public places.
