PROJECT PROPOSAL Introduction Floods are a common occurrence in most parts of India, especially in the monsoon months of June, July and August. Multiple studies show that the deforestation in the Brahmaputra watershed has caused an increase in the damage that floods cause every year. While the Brahmaputra flows in multiple states, Arunachal Pradesh and Assam suffer the worst floods, almost every year. Floods and similar natural disasters are violent in nature and often leave a wake of destruction in their aftermath. This makes recovery a long and tedious process. The obvious solution would be to move away from such floodprone areas and find livelihood elsewhere. But what about people who do not have a choice? Is there a way to ease their damage and repercussions of floods, and help people gain a semblance of normalcy faster, after the damage is done. Taking the context of Lakhimpur district, in Assam, this project will revolve around creating solutions to help the people living in flood affected areas. Background Research and Significance Usually triggered by heavy rainfall, and worsened by the regular deforestation along the Brahmaputra basin, Assam is regularly affected by floods. According to a report released by the Assam State Disaster Management Authority (ASDMA) during the floods in 2016, Lakhimpur district in Assam was the worst flood hit district, with around 21,200 people affected. The same flood report released on 28 July 2016 states: · Districts affected in Assam: 22 · People affected: 17.94 lakh · Total Crop area affected: 2,13,251.52 hectares · Most affected districts: Morigaon, Jorhat, Dhubri, Barpeta, Lakhimpur, Golaghat, Sonitpur, Goalpara, Bongaigaon, Dhemaji and Darrang · No. of Relief Camps opened: 517 · Relief Distribution Centres: 186 – sheltering 2,29,544 inmates

Secondary research infograph
During floods, the government undertakes measures such as setting up relief camps, providing temporary shelter, distribution of clean food and drinking water, distribution of relief kits, and so on. The government also takes up projects such as construction of embankments and flood walls, anti-erosion and town protection works, flood forecasting and warning, and so on. But oftentimes, measures such the building of these embankments provides little to no relief. Further measures must be undertaken by the government to mitigate the damage caused by floods. For the project primary research was conducted in flood affected villages located in North Lakhimpur district in Assam. Primary research was mainly conducted through the following methods: Priority Cards: Using vector image representation of the main resources lost/ needed during floods (like food, water, communication, shelter, etc.,), we asked people to pick and prioritise based on their needs and availability of resources to them. Picture Cards: Using pictures of previous year’s flood in the same area, the villagers were asked to describe them in order to jumpstart storytelling and create in us a better understanding of the user and build empathy. Interviews: Through informal conversations the villagers seemed to open up about not only their problems, but the village, their culture, their connect to the land, and so on. Participatory Mapping: By asking the villagers to map their area, we gained a better understanding of not only the village but also the population of the village and surrounding areas, how trade occurs, where the business hubs are, what places are the worst affected by floods and so on. From the primary research done in Lakhimpur, it is apparent that while perennial/ annual floods are common, the people living there are used to the flooding and take precautions to save their houses and belongings during the flood. Most houses are built on stilts, with existing mechanisms to make a second floor within the house itself in case water enters the house as well. Existing solutions include rescue shelters installed by SELCO, which are powered by solar panels. While some residents do use the shelter during floods, they only provide so much relief. Some houses have sturdy boats to help move around when the water levels rise, while others resort to rafts made from locally available material like bamboo and banana stem.
In villages where the water currents are mellow, bamboo bridges are installed to move from one house to the other. When the floods hit, NGOs do provide the villagers with torches and inflatable boats, but by the time the next round of floods come (which is the next year), the survival kit is either lost or rendered useless. Other solutions designed by the villagers themselves, include a portable stove that makes cooking inside the house easier, and is also simultaneously used for drying clothes during floods, using polythene bags to save important documents, and so on. Despite these solutions, villagers still face difficulty and hardship during floods. What is essential is design interventions to pre-existing situation, so that the villagers there can easily use/ adapt to the solution in order to provide some relief from the flood. Key Findings While the primary research provided us with a rich resource of information, some of the key findings are listed below, · The rescue shelters built by SELCO has a capacity for over a 100 people while the village population is 480. · People prefer to move into houses which are not flooded by water or build a second floor within their house rather than leave their homes. · While people are aware of when the flood will hit, there is no proper arrangement made for storage of food and provision for clean drinking water. People make do and for the few days the flood strikes until relief from the government and NGO arrives. · Relief is usually provided after the flood and not during. · Water inside the stilt houses stays for a few days while the water level in the village areas can take anywhere between 3-5 months to clear. During this time, schools remain shut, and normal life as is comes to a standstill. · Non-existence of a waste disposal system contributes to further contamination of water during floods. · No hospitals or clinics are present near the villages. Locals depend on traditional forms of medicine like locally grown medicinal herbs. · During the floods, food, potable water, energy, hygiene and sanitation are major areas where people face problems especially because diseases like malaria, typhoid, dysentery become common, and clinics and medicines are not readily available.

Abstract When floods strike, the first things to disappear are basic necessities like shelter, electricity, food, and clean water. This not only leads to loss of life, but also extreme suffering for those alive. Contamination of water can lead to transmission of diseases like cholera, dysentery, and typhoid, and is said to cause over half a million deaths annually, worldwide (World Health Organisation, 2018). Yet this is largely preventable. The paradox of floods is that there is water everywhere but not a drop to drink. Design Brief Done in collaboration with SELCO, this project will deal with solutions relating to potable water in the context of floods, using renewable energy and frugal resources. To design a solution for potable (drinking) water accessibility for marginalised communities in flood affected areas. Direction and Approach · Use natural methods and materials (Preferably locally available materials) to obtain clean water. · Try and make it easily accessible especially during floods. · Try and see if the flood water itself can be cleaned to provide clean drinking water. · See if existing RO water purifiers can be powered using solar energy as decentralised systems powered by renewable energy makes things more accessible, especially during times of floods, when grid power is shut down. · Inspirations can be drawn from existing solutions for flood relief or from seemingly unconnected products from different worlds.
Objectives · · ·
To come up with a flood resilient product/system intervention for flood affected communities. To make sure that the solution is easy to use and maintain by the user themselves. To include renewable energy and frugal resources in the aforementioned solution.
Expected Results A product/ system intervention for flood affected communities relating to potable water that can be used during floods as well as otherwise. Research and Design Methods · Secondary research about flood, existing solution, materials, methods, and so on. · Primary research: Interviews Picture card interviews (priority mapping and storytelling) Participatory mapping · Brainstorming methods: Affinity maps, mind maps, lotus blossom method, body storming, mind maps, low-fidelity prototyping, and so on. Timeline and Resource Line Post Seminar 1 · ·
Talk to experts on natural water filtration and water filtration systems. Talk to people who have done relevant projects on water cleanliness
· Ideate and iterate through rapid sketching and making low fidelity prototypes. Conduct simultaneous user testing for these prototypes. Post Seminar 2 · Incorporate User feedback into prototypes. · Refinement and further exploration of material, form, function and aesthetic. Use local/ easily available material for exploration. · Create systems for said product and represent through mock-ups and prototypes. · Further user testing and feedback. · Final prototype making after incorporating feedback.

PRIMARY RESEARCH
The communities we visited mainly included the Patnas commmunity near Bordubi Malual, the Mising Tribe: Alichiga villiage and near Majuli island.
The people of these tribes were welcoming and friendly and although they couldnt speak hindi, they put in a lot of effort in order to understand us and interact with us.
While there were a few children who could speak hindi, we had guides from IGSSS who translated Assamese to English for us. The four main reaearch methods we used were:

Interviews
Possessions of the tribes we visited. While they didnt own a lot of things, their most important possession was their land, and solar panels if the house had one. Almost all houses had a handloom, and most of them had boats stored beneath their houses.
Houses of the tribes we visited. The older houses were made entirely of bamboo while the newer ones used a mixture of concrete beams and bamboo. None of the houses had toilets inside them. Most of the cattle lives beneath the house.
A lot of the houses had GI roofs while some had put thatch on top of the GI roof.

KEY FINDINGS
During the floods, food, potable water, energy, hygiene and sanitation are major areas where people face problems especially because diseases like malaria, typhoid, diarrhoea are rampant, and clinics and medicines are not readily available.
KEY FINDINGS
Non- existence of a waste disposal system contributes to contamination of water during floods.
No hospitals or clinics are present near the villages. Locals depend on traditional forms of medicines like herbs which are grown locally.

SECONDARY RESEARCH ABOUT RAINWATER HARVESTING Research about rain water harvesting, the technical specifications as well as the DIY methods that peole has come up with. These gave me inspiration for some of my ideas.
PRIMARY RESEARCH ABOUT RAINWATER HARVESTING
Visit to Rain water harvesting stores in KR market to find out the kind of parts that are available and the value of the same.
FURTHUR IDEATION
Purpose: To harvest the rainwater through a network of pipes attached to the side of the house.the pipes distribute the weight evenlt amongst the pillars and use gravity to direct the flow of water into the house. A tap is available inside the house to access the harvested rainwater. Target User: Families in flood prone areas, where floods occur primarily because of rains. Houses that do not have/ cannot afford GI roofs. Subsidiary User: People looking for frugal ways to harvest rainwater. Situation of Use: When sources of clean drinking water are limited. Who Owns it? How?: Families own it individually, or together with other families. It is a one time investment, which can be paid through monthly EMIs.
FURTHUR IDEATION
Purpose: To harvest the rainwater through barrels attached to the side of the house. the barrels are half filled to make them floatable during the flood as well as reduce the tension on the cement beam. A hand-pump is used to access the water. Target User: Families in flood prone areas, where floods occur primarily because of rains. Houses that do not have/ cannot afford GI roofs. Subsidiary User: People looking for frugal ways to harvest rainwater. Situation of Use: When sources of clean drinking water are limited. Who Owns it? How?: Families own it individually, or together with other families. It is a one time investment, which can be paid through monthly EMIs.
FURTHUR IDEATION
Purpose: To harvest the rainwater through an elongated gutter pipe along the side of the roof. again gravity is used to direct the stored rainwater. Target User: Families in flood prone areas, where floods occur primarily because of rains. Houses that do not have/ cannot afford GI roofs. Subsidiary User: People looking for frugal ways to harvest rainwater. Situation of Use: When sources of clean drinking water are limited. Who Owns it? How?: Families own it individually, or together with other families. It is a one time investment, which can be paid through monthly EMIs.
REFLECTION Since I liked the idea of using gravity to direct the flow of the water, I decided to make technical drawings between 1 and 3 to be able to choose which idea to take forward better. for this I first started with a dimension drawing of the house.

SWOT ANALYSIS IDEA 1 STRENGTHS
WEAKNESS
Readily Available low cost material. Weight of the water is evenly distributed along the beams.
Cleaning and maintainence of PVC pipes needs to be taken care of. Danger of leaks.
OPPORTUNITIES
THREATS
Uses existing structure of the house. Is customisable for any amount of water needed to be stored provided the beams can hold up the weight.
Danger of overflowing of water. Water might need to be boiled.
TECHNICAL DRAWINGS IDEA 2
SWOT ANALYSIS IDEA 2 STRENGTHS
WEAKNESS
Weight of the water is evenly distributed along the beams.
Needs custom made troughs. Water is constantly exposed to air through gaps in the roof. No provision for first flush. Maintainence is an issue as it is not easily removable. Needs extra structures in place for extra support. Might not work on full bamboo houses.
OPPORTUNITIES
THREATS
Uses existing structure of the house. Is customisable for any amount of water needed to be stored provided the beams can hold up the weight.
Water will need to be filtered and boiled. Might become expensive. might become too heavy and lead to breakage as it rests on the wooden roof beam as well as the concrete beams.
REFLECTION Since using the PVC pipes was a lot more cost effective due to the easy availability of the material and a lot more forgiving on the existing structure of the house in terms of weight and pressure, i decided to go ahead with that idea.
PROTOTYPE MAKING PROCESS
I decided to make a 2ftx3ft scaled down model of the house to showcase my idea. While the model is not accurate in parts and size it does show the base idea well.
FINAL PROTOTYPE
CONCEPT NOTE When floods occur in Assam every year a common problem is obtaining clean water for drinking, cooking and sanitary purposes. This idea aims to solve that problem by harnessing rain water. Floods are a common occurrence in Assam mainly due to heavy rainfall they recieve during the months of June and July. Rain water is also one of the cleanest available sources of water. This idea showcases how the rainwater can be harnessed and stored alongside the house inside pvc pipes so that the cost of building a tank is reduced and the user does not have to spend electricity in bringing the water upto the house from the tank.
FINAL REFLECTION This project has been a great learning experience for me. I love travelling and interacting with new cultures and people, but it is often that we take for granted that we will find people who will speak a common language. Understanding the pain points of the people living in flood affected regions in Lakhimpur despite the language barrier was challenging but enlightening in the fact that it taught me about different tools you can use when spoken word is not an option. In this project I learnt that design isn’t always about coming up with something entirely new, it is about analysing and observing the situation so that the correct solution can be applied. I started out with trying to come up with a filtration system that would low cost and easily maintained. I then went into researching about solar powered RO filters. But after interacting with my professors, I was forced to relook at the information in front me. Looking at it in a new lens helped me realise that it is not a filtration system that is needed but in fact a system for them to store water. From here came question about source, space and infrastructure which finally led me to the design I ended up with. Along with this I also learnt a lot about using mapping techniques to analyse research and how to listen to the user and not enforce our preconceived notions onto them. Of course there will always be ways to improve not only my design, but myself and my methods further, but in these last four months there has definitely been a leap in my learning and polishing of my skills as a designer.
