Innovation is alive and kicking in sanitation

June 8, 2013

It is not only Bill and Melinda who are funding innovation in the toilet business :).

When millions of people all across India start to build toilets in rural areas and in small towns they do not have a sewerage system to connect to. They usually build a single pit lined with concrete rings and connect the toilet to it. In India the toilets too are pour flush toilets and not the dry toilets prevalent across much of Africa.

Eventually these pits do fill up, depending on many factors such as the depth of the toilet pit , the number of users, their diet , the soils ability to infiltrate water etc etc.

Eventually they will fill up

Jugaad to the rescue – These tablets if placed in a full pit will ‘burn’ it and reduce the filling making it possible to use the pit for more time

Image

These are called ‘pit medicine’ in Kannada and are available across many small towns. Each set costs Rs 50 ( 1 US $) and is a single time use.

Taa-daah …Honey-sucker to the rescue. Will empty the pit toilet in minutes.

Now imagine a set of tablets which can also sterilize the pit content and kill all pathogens . The pit sludge can then be easily removed using the ‘Honey-sucker ‘ and spread out on the fields in the rural areas and in the small towns to act as fertilizer for the crops.

..and oh by the way , one of the fastest growing business around small towns and villages is in these pre-cast concrete ring making. All you need is an empty site , a steel mould for pouring the concrete , some cement and GI wires /streel rods and you are in business. As there is a huge government push for sanitation demand is picking up in villages for these rings for the toilet pit

The concrete ring makers

                            All over South India , in small towns and large villages, concrete    rings for pit toilets are being made

This is what we will be working at in the near future.
