Ecosan toilets

I have already procured a pair of ecopans of different design from Biome Solutions in Bangalore. This design has influenced my current thinking which I will implement in the second toilet that is being planned. What difference does this design make? It is similar to the earlier one except that it has only one drop hole, a urine pan and a wash-up pan inline with the other two. ecosquat.jpg

I plan to dig a hole in the ground and place a used chemical barrel of about 60 litres in the hole. These barrels are readily available, once used. Pick ones that have carrying handles and a tight lid. Around the barrel with a low wall of about a foot in height built forming a square of about 4’x4′. Resting on this wall is a hinged waterproof ply board. In it the shape of the ecopan is cut out and fastened. When the ply floor is down the drop hole is positioned exactly over the barrel opening. Urine and wash water lead-away pipelines are fitted and an odour vent installed if found necessary. Once the barrel is full, the ply-floor is lifted, and the barrel’s handles are used to hoist it out of the hole and an empty barrel is inserted. Necessary canopy is built over the system to keep away rain water.

The advantages of this arrangement over the previous are many:

  • Lower first cost
  • No raised platform, steps or grips required
  • User is less daunted since no climbing is necessary
  • Aged and disabled friendly
  • Wash-up pan is inline and requires a mere shuffle back to reach
  • Capacity is not determined by vault size but by frequency of barrel replacement
  • Composting is off-site
  • No manual scooping out

Work on this version will begin in a few weeks.

  1. If any of you are interested the ecopans and ecowashes seated and squatting that DV used here are from us at EcoSolutions. Have a look at the website to see various installations and ideas. well done DV, hope you are happily accumulating compost and merrily diverting urine. Best to you all, Paul Building ecological toilet systems in India since 1994

  2. I would love to see a diagram of your invented system DV. Although I can imagine the general design, it seems so much more efficient that I would like to completely understand. Perhaps if you were to draw it up, and submit it for production, you might have many people wanting one. Maybe the ecosan man would appreciate a better system and make one better. I am completely amazed that you had to search for the instructions. When you put your knowledge of this and your better system together, it seems he could use your advise considerably! Or, perhaps another manufacturer.
    Another thought: if a platform was positioned over the system of pans, with a wash sink next to a squatting seat, wouldn’t the whole experience be more beautiful?

  3. I had read about ecosan at different sites but nobody gets into the details of actually deploying one as you do. Keep up the good work! I look forward to these valuable insights as you progress…


  4. Hello Mr. Sridharan,

    You didn’t give any details about the Western-style pan. Did you try installing that too?
