Gulbarga visit

On 8th August 2013 Shelter Associates sent a team to Gulbarga in Karnataka to review a sanitation project currently underway by the Green Sanitation Foundation (GSF).  The GSF toilet system in Gulbarga uses enzymes and nutrients to accelerate the natural process of bacterial decomposition to reduces human excrement and urine into low grade water that can be output into the ground soil or into surface water drainage systems.

This project is of interest to Shelter Associates due to the potential of its application in situations where drainage connections are not available, such as peri-urban environments (Sangli & Miraj) and slums and informal settlements in urban areas which are not connected to the municipal drainage system (Cham Cham Nagar in Pune).

Ultimately the Shelter Associates team could not determine if the technology was working as the project had only been running for 2 months and it takes at least 3 months for the faeces and urine to be decomposed to water, disinfected, and emitted from the 300 litre tank beneath the toilet.
