6 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

7 Jar being made Info. and Pictures from:

8 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

9 Gutter Setup

10 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

11 Example of a Filter System

13 Our Final Solution  Galvanised steel guttering  ‘Jar’ storage tanks  Sand, Charcoal, Gravel filter  Hand pump

14 rainwater-harvesting-through-construction-water-jars Our Final Solution

15 Costing and Future Planning The initial cost of the materials needed to build the rain-harvesting mechanism for each house. Materials Cost Charcoal - Gravel - Sand - Hand pump (Suction Pump) £37 Jars £35 Galvanised steel ≈£40

16  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.
