About Urine Diverting Toilets

Urine Divertings WCs with unique features!

Using a urine-diverting WC makes it more efficient to flush as little water as possible. On average, a person visits 6 toilet visits per day. Since 5 out of 6 toilet visits contain only urine the small rinse in the urine bowl is used 5 of 6 times. The average water being consumed per flush will then be well below 1 liter in an EcoFlush, which then is 80-90% less water than all the usual toilets on the market! EcoFlush flush and built-in water trap are completely unique. For even less flushing, EcoVac Sorting Vacuum WC, or EcoDry Recreation Room.

Uniqe built-in water trap!

Now it's even easier to install and use our UDTs. The water lock is located underneath the urine bowl and makes it possible for a quick and safe installation, and no other need for a water trap for the urine piping. It is also extremely easy to rinse the urine drain with water by lifting the cover and rinsing with a hose.
