Seeking for an idea we went intoIndia’s rural background and cameacross a fact that Pitcher Pots are ofimmense importance in numerous
elds!
• So implementing this thought wehave innovated a new techni"ue to
store drinking water in ruralareas#but this time on a larger scale!

• Pol'plastic tanks are made up ofpol'eth'lene#a ./ based food grade plastic !
0ater stored in such tanks for a longerduration cause water borne diseases due tothe harmful e1ect of petrochemicals presentin pol'eth'lene!
• 2ven when their serviceable life has endedthere is a hunk of plastic that takesgenerations to break down and release to3insas it does so!
• Installing pol'plastic tanks at house roofsacts as (ust water reservoir and then arisesthe need to cool it b' the use of water coolers
which re"uires additional mone' and space!

• It will be connected to the lterations'stem shown in above slide!
• Puried water will be stored in thesepots
• 7ur idea of storing water basicall'stands on the foundation of multiplepot s'stem!

temperature of water stored insideinner pot will lower down b' theprocess of evaporation through poresof inner pot!

This provides a coolingatmosphere around the inner potwhich keeps water inside it coolfor a longer duration!

• The outer pot installed keeps the holdthe sand and also provide an additionalla'er for cooling water!
• +urabilit' of pots ma'be a concern sofor that whole of the pot s'stem will be
surrounded b' a concrete wall and eachpot will be covered with the cotton lid!*nd with this our completel' insulatedwater cooling s'stem will be read' whichcan be used for drinking purpose with no

• This water can be used fordirect consumption b' the
villagers!• Clean and cool water will be
available easil' in the
vicinit' of their houses!• 2ven taste and essence of
water of pitcher pot is ver'
good due to moist cla'!• This reduces the threat of
water borne diseases in the
village!

Installing this t'pe of s'stem at asingle place in a village willcomparitivel' occup' lesser areathan setting up an individual tankin each house of the village!
This practice is immensel' coste1ective as pitcher pots are ver'cheap and even the materials used
for purication are easil' availableat low cost! It will provide emplo'ment to a
large mass of village as thisrocess will brin revolution for

The sand surrounding the inner potis kept moist b' watering it two
times a da'!
This provides a cool atmosphere atthe surface of the inner pot which
keeps the vegetables fresh for aduration of 9B da's!
