Finalists Conclave, AEGIS 2022. Script of the presentation - https://www.scribd.com/document/688949067/SCRIPT-for-NIRMAL-JAL-Preventing-Water-borne-diseases-in-India TEAM MEMBERS Shavika Kapoor (2020 batch) Shreenidhi Panigrahi (2020 batch) Charitha Vasireddy (2020 batch) Swetha Rani Savala (2017 batch) Gandhi medical College, Hyderabad. Public health ideas for addressing water borne diseases due to contamination and lack of hygiene practices. We came up with these ideas to increase supply of safe drinking water, increase awareness among the masses about hygeinic practices, coordinate with government sectors and integration into the existing healthcare system. #Ideathon #healthcare #public health #solution #spm #community health #socialandpreventivemedicine

3. WATER WATER EVERYWHERE…

5. AND NOT A DROP TO DRINK…

7. PROBLEMS WITH ACCESS PROBLEMS WITH SAFETY OF DRINKING
WATER
Groundwater depletion -
exhaustion of a primary
drinking water resource.
Caste-based discrimination
These groups have to resort to
contaminated water for their needs.
Contamination of water due to
open defecation, chemical
wastes, organic wastes,
cultural practices, lack of
proper hand hygiene etc.
Lack of awareness
about available
purification
techniques.
Some settlements are very far from the
drinking water resources.

8. WARKA TOWERS
• An alternative source of potable
water in communities with low
access to drinking water.
• Condenses water vapor, dew, and fog
present in the atmosphere into water
which can be stored, filtered, and
distributed.
• Can also be used to collect rainwater.
• Does NOT require any electricity.
• Reduces stress on groundwater.
• Built from sustainable, locally
available materials (bamboo, wood,
dry straw etc.) and easy to maintain.
developed by Atruio Vittori and Andreas Volger

9. SCOPE FOR INDIA
• Most conducive conditions for maximum output
are relative humidity (50-70%) and temperature
20-40⁰ C.
• Based on prevailing conditions, up to 100 L of
drinking water per day can be obtained from one
tower.
Areas where maximum
output can be
obtained

10. MAKING RAINWATER POTABLE
Cost-effective model for harvesting Community-collection model of harvesting

11. VARDAN WATER PURIFIERS
Vardan water Purifier by Sustainable Livelihood Initiative India (SLII) is an extremely affordable and sustainable solution
to the global problem of water purification.

12. EARTHEN POT PURIFIERS
Earthen pots filled with naturally purifying elements such as sand and gravel could be used as an eco friendly and cost
effective method of water purification.
‘JAL-PARI’YOJNA- Cottage industries employing underprivileged women to make earthen pot purifiers could be
initiated. These purifiers can later on be supplied to every household in a rural community on a non-profit basis.
Similarly, workshops can be conducted in schools to teach children how to make such filters at home.

13. COTTON SARI FILTERS
• Works at INDIVIDUAL level ; targets populations whose main source is surface water.
• Water is filtered through a 4-layered cotton-sari cloth; observed reduction in coliform
• count and 48% reduction in incidence of cholera
• Easy to use
• No extensive training
• Easily put into effect
• No additional cost
• Accepted readily at end user level
• No water wastage
• No electricity {Sustainable}
• The model can be enhanced by combining filtration with sterilisation
• Water can be passed through glass pipes; set-up is exposed to the sunlight; the action of UV
rays and heat will sterilise the water.
• Done at POU (point of use)
• When boiling can get too costly/not possible
• High compliance (follow-up revealed ⅓
continuing}
•Useful in flooded areas or other disasters

14. THE DRINKABLE BOOK
• The drinkable book consists of folia water filters that are papers
made up of cellulose nanofibers impregnated with silver or copper
nanoparticles (with antimicrobial properties)
• Contaminants removed: Bacteria, Viruses, Protozoa, Dirt, Worms,
etc.
• A single filter provides 20 L of safe, germ free water.
• Target population: working class consumers, rural population
• In Bangladesh, water could be purified at the cost of 20 Taka (INR
15.91) per 20 litres.
developed by Theresa Dankovich

15. MILLE FEUILLE- “A THOUSAND LEAVES”
• Its a non-woven hot pressed filter paper made from 100%
native nanocellulose fibres of Cladophora
• Among the limited viral filters present, this appears to be
highly effective and affordable
• Capable of removing the worst case model viruses {non
enveloped parvoviruses}
• Longer lasting, Easy to carry
• Made of cellulose from cladophora - hence vastly
abundant, non-toxic, non-chemical and inexpensive
developed by Uppsala University, Sweden

16. BOILING
• BOILING water remains the
• Safest
• Oldest
• More accessible
• Most efficient method of purifying water.
• Campaigns such as ‘Jal Ubaalo, Swasth Sambhalo’ can be introduced to
promote this.
• Boil water advisories - given out in cases of emergencies
• Most harmful organisms can’t survive at water’s boiling point of 212F
• Retainment of essential minerals
• Adding salt is advisable - natural disinfectant; directly kills certain bacteria by
osmosis

17. WATER DECONTAMINANTS
Decontaminating agents like naturally available Tulsi leaf extract, Moringa seeds, mucilage from prickly pear cactus
and brushite-calcite can be used to purify water. The treatment is simple, cost effective, eco-friendly, accessible for all.
It can be practised with little effort at rural community households.
TULSI- antimicrobial and defluoridating agent
MORINGA SEEDS- removes particulate matter including clay and silt particles, organic and inorganic matter.
PRICKLY PEAR CACTUS- antibacterial and removes arsenic
BRUSHITE-CALCITE- defluoridating agent

18. BIOREMEDIATION
• An emerging technology that makes use of culturing
microorganisms manually at the resource to break down
organic and chemical wastes in polluted water.
• Can be used in large-scale operations like decontamination
of rivers, lakes, groundwater and soil.

19. HAND HYGIENE
SOCIAL PROJECTS TO PROMOTE
HAND-HYGIENE
SOAP SACHETS CAN BE PROVIDED
WITH PM POSHAN SCHEME
HANDS-FREE WATER
DISPENSERS
USING SOAP CHALK STICKS AND TIPPY-TAP
WATER DISPENSERS IN SCHOOLS

23. CONCLUSION
Access to safe drinking water is the
birthright of all humankind.
Improved drinking water supply would
contribute to country’s prosperity in
various aspects.
“Thousands have lived without love, not
one without water.” — W. H. Auden
Hope millions of kids like Arjun face no
dearth of secure water in the near future!
