Design Specifications

The Ecodry urine diverting dry toilet is made of porcelain. It is 450 mm high, 395 mm wide and 580 mm deep. There is a premounted watertrap in the urinehole and a 75 mm long and 19 mm in diameter premounted urine hose. The waterpipe is stainless with a flexible R15 and 8 AA batteries are included and premounted to run the fan. The toilet seat is made from plastic. The complementary Ecodry Box has a capacity of 100 liters. A barrel of 80 liters normally lasts about 3 months for a family of 4. Emptying of the ecodry box hence has to be done 1-4 times per year. A big garbage bag is suitable to place in the box. The urine can be mixed with water (25% urine and 75% water) and applied to plants as a fertilizer. The feces are stored for about 3 months during which they are dried and when emptied the contents of the Ecodry box of 100 liters weighs 10-20 kg. The contents can then be moved to a composting unit for composting. The toilet is installed over a container and the urine hose is connected to a container for the urine. A 200 mm pipe connects the toilet with the feces container. A fan reduces odour and makes the waste dry faster so that pathogens are reduced. If desired, water can be connected to the toilet so that a small flush can be made in the bowl. If not, a small cup of water can be applied now-and-then to reduce the risk of urine odour and crystallization of urine in the urine hose.
