2. Eco-toilets from Sweden since 1991. Wostman
Makes flush toilets possible everywhere!
Extremely energy efficient
• The engine is only used for a few seconds
when flushing. Energy costs could therefore
be around 1$ per year!
• Consuming about the same amount of energy
per year as an electric/combustion/
incineration toilet makes on a single toilet visit!
Reliability
• EcoVac® is specially designed to hold highest
operational reliability. No valves or cutting
pumps to pass through the waste.
• The pipes are empty which minimizes the risk
of freezing.
• The toilet can be flushed even in case of
power failure (if installed with regular WC drop
ratio).
Saves more than 90% water!
• Thanks to air instead of water in the pipes
EcoVac saves huge amounts of water.
• Extremely low-flush with 0.6 Liter!
• Compared with regular toilets you can save
about 90% of water. Compared with the so
called ”low-flush” toilets, you save about 80%.
Empty the septic tank once a year!
• EcoVac makes it possible with about 3000 toilet
visits on a 3000 Liter tank.
• One toilet visit fills about 1 Liter in total (count
with 0,6 liter water + 0,4 liter waste).
Works with many kinds of tanks and
collection barrels.
• Works with most types of septic tanks or bio-
units.
• Can also be installed on your old tank! Check
out the rules that apply in your municipality.

EcoVac® uses a unique ”soft vacuum” to flush the toilet. Think of it as a mix of a regular WC and an
airplane toilet. The vacuum motor is activated for just a couple of seconds while flushing and removing
the waste all the way to the tank in a few seconds. There is only water inside the toilet and not in the pipes
like with regular toilets.
