Comment from Cesar: Lots of interesting variations! What do you think will be determinant for the users? Simplicity? Maximum volume of water held? Maintenance? Reusability? Think hard about the questions you want to ask the Rohingya students.
Also you can ask their favourite fish. And what sort of environment is best for these fishes. In different cultures people like different food. Growing a type of food that is nutritious and popular would help a lot.

Each section of the refugee camp is managed by a different WASH group

1. very practical and detailed drawing 2. The scale of the design is feasible. But we can consider how to use locally available materials instead of shipping, so they can be replaced if damaged 3. Quite complicated 4. Like the idea of incorporating the system into existing structures, importance of teaching in order for it to be sustainable
5. Wondering about access to water? Scale limitations, can you really farm fish in the tanks? 6. Robbi was interested in the idea of using plastic bottles and stack them or lay them out to make a vegetable farm. These used bottles are a big resource to the area
Further research
Keep developing designs - 3 detailed sketches of your design and technology
Sketches with
- Materials
- Dimensions, scale
- Colors
Choose a design to prototype
Bamboo + Bucket have been chosen as the prototype design.
Prototype Material:
- Rope / String (Sardonna)
- PVC Pipe/Acrylic pipe (Sardonna)
- Plastic Cup (Jerry)
- Sponge (Jerry)
- Electric pump or with solar panel (Oscar)
- Styrofoam box or Bucket (Oscar)
- Discarded Tea Leaves (Sardonna)
Rapid Prototyping
Bamboo → PVC pipe [Prototype]
Prototype Making process:
Tying the PVC pipes for the structural framework
Cutting the foam
Constructing the Styrofoam fish tank
Drilling holes into the PVC pipe for the plastic bottle planters
PVC pipes structural framework
Setting up the slanted planters
Video Prototype Role-playing (1 minute)
Business Model
Instruments
Maintenance of the fish tank
Sponge/ filter cleaning - use paperclip as the tool to retrieve the filter sponge
-Catching the fish - fishnet / barehand
-Cleaning out the water from the fish tank
Planter
-Harvesting the plants - basket to collect the produce
-
Instructions
Feed the fish on a daily basis and harvest the plants every few days.
When harvesting the plants, snap off the outer leaves only. Collect the leaves in a basket.
Provide tank and water pipe maintanence:
- Unplug the sponge, scrape off the solid attached into the planters every few days
- When the water quality is below a certain level, take out the fish into an empty bucket, and change water
Prototype Amendment
Education Material Version 1
Updated Education Material
Final Prototype
Bamboo Prototype Making process:
Measuring and marking up the cut location
Slicing the bamboo into half with bandsaw
Step 1: Start at mid point of the rope
Step 4: Tighten and go under the bamboo
Step 7: Cross in front
Step 10: Tighten the connection
Cutting the bamboo with portable electric saw
Bamboo materials to be assembled
Step 2: Wrap around and tighten
Step 5: Forming a cross at the top bamboo
Step 8: Tie a knot to secure the bamboo
Continue the bamboo tying process
Slicing the bamboo into half with bandsaw
Tying the bamboo framework
Step 3: Wrap around the top bamboo
Step 6: Cross over at the top
Step 9: Tie another knot at the same location
Project Manage
To help you manage your project, I suggest using a simple project management system like a Kanban/Trello board. Don't forget to
- Be specific with the task. Link to the source
- Assign one person per task. Of course, you can collaborate, but one person is responsible for the completion of one task
- Deadline. So that your team can coordinate and nothing falls between the cracks.
