MAH02621.MP4
Vacum sucking a pit latrine
the honey-sucker can reach 250 feet
It has eliminated manual scavenging
There are 300 of them in Bangalore City
The trucks are indigenously designed
Nutrient value is recovered
A protocol for use is necessary
As is an institutional and legal framework which includes this service
Over 100,000 houses are estimated to be currently served
Eco-san at play
Farmers have understood the nutrient value
..and are even composting it and re-selling it
Completely in the informal private sector
But how to avoid soil and groundwater pollution ?
Nutrient analysis in progress
Great N:P:K VALUE WITH MICRO-NUTRIENTS
More science is required
Concrete rings being made to line pits of the latrine
This too is in the informal sector
Else sewage ends up in rivers
Polluting water
Foam rivers …
The honey-sucker solution ?
