Options: Tank Construction Bamboo Tank -sustainable: recycle
bamboo baskets skill for the villagers -varying capacities -bamboo
plantation far from village -relatively expensive -bamboo is slow
to mature Jars -sustainable: skill for villagers local / readily
available materials -form of income -reusable moulds -varying
capacity/heights -heavy / hard to move -danger of stale water

Options: Guttering Materials Galvanised Steel -long life
-corrosion can be overcome -recyclable / reusable -more
distributors / manufacturers -heavier -relatively expensive -water
that runs down steel guttering is cleaner PVC - cheap -lightweight
-less weather resistance -very difficult to recycle, it is a
thermoset polymer -harder to attach -much shorter life span Wood
-has a short lifespan -not a very clean form of guttering

Options: Filter Materials Pebbles -cleaner water -not
sufficient on its own Gravel -prevents clogging of pipes with
larger obstructions -not sufficient on its own Sand -pre filter for
particulates -not sufficient on its own Charcoal -absorbs
agro-chemical contaminants -need a large amount per person / litre
(4.5kg per person per year) - readily available in villages These
will be combined to make the filter as it will be very cheap

Convenience Safe water with adequate sanitation. The
possibility of maintenance by village workers Have scheduled
maintenance instead of breakdown maintenance. Ensure this
development boosts their livelihood by creating commerce, industry
and developments for everyone in Devikulam. Reference Community
