Grassroots is implementing an individual and effective approach using technology
designed by geohydrologist Dr Tim Rees. Dr Tim Rees, a British geohydrologist living
in India since the 1960s, pioneered an appropriate technology design in the form
of an Infiltration Well, which serves as a Protected Intake Structure for drinking
Tim’s innovation is an infiltration well that collects water from subterranean water
capillaries, which are located deeper than the traditonal naulas. The Kumaon Artisans
Guild are able to construct the well by hand without the need for heavy machinery.
This makes installation possible and more affordable in the most remote of villages.
Most importantly, These community drinking water systems are operated and maintained
by the people themselves.
Over the past decade, more than 55,000 people from 370 communities in far flung watersheds
have gained access to enhanced quantities of safe drinking water through adoption
of this intermediate technology application.
Grassroots and the communities we work with are extremely grateful to Dr. Tim Rees
for his contribution.
Over the past decade 2000 families across 200 villages in six districts of Uttarakhand
and Himachal Pradesh have invested up to 60% of the cost which amounts to around
Rs. 8,000 per unit. Demand for these grants far exceeds our available funds. Pleaseclick here to donate to the Sanitation Grant Fund.
A twin pit water seal sanitary facilities is promoted, where relevant using rainwater
harvested in underground tanks. Over a period of two years the waste in the pit
becomes composted and is easily emptied out to be used as fertilizer, as the pits
are covered with removable slabs.
Grassroots’s Blue Schools initiative combines the installation of rainwater harvest
systems and sanitation units in rural schools with an environmental education program
in the classroom. In collaboration with the International Rainwater Harvesting
Alliance and Ministry of Water Resources, Govt of India, Blue Schools is helping
to drive awareness on climate change, ecology and resource management in over 30
schools in Himachal Pradesh.
A rain water harvesting unit works simply by collecting rain water pooling or running
off the roof of a house and channelling it into a tank, where it can be stored. Before
entering the tank, the water passes through a chamber where solids like leaves and
rocks are filtered out. The water can then be used for washing, irrigating fields,
and for cooking. The stored rainwater reduces the pressure on scarce spring water
used for drinking.
