Water and sanitation

Clean water is vital to basic survival and effective sanitation is essential to maintaining health and hygiene.  Often neither is available to poor, marginalised, or displaced communities.

While working with development projects in India, I have been involved with many initiatives where water and sanitation were a very necessary component.  In this section I would like to share my experience of the long-term impact of some of these interventions, as I have followed their progress in the Tibetan settlement of Doeguling in Karnataka, south India. 

• Windpumps for raising water
• Water storage containers - ferrocement
• Twin-pit pour-flush composting toilets
• Natural De-centralised waste water systems (DEWATS)

In particular I would like to draw attention to the considerable contribution to water and sanitation systems technology made by:

• The Auroville Building Centre of the Centre for Scientific Research, Auroville, Tamil Nadu, India. 
• Aureka, a unit of Auroville. 
• The Housing and Urban Development Corporation (HUDCO), New Delhi, India.
• Sulabh International, New Delhi, India.
