Solar Box Oven
Cook with the power of the sun
With this oven you can cook without using electricity or burning fire wood.
Grey Water Sediment Filter
This grey water sediment filter removes dirt particles from grey water. You can use the clean water for your garden, cleaning, or flushing the toilet. If you further treat the filtered water with the SODIS filtering method, you might even cook or drink it (only if it’s free from chemicals, like laundry powder).

- Scissors
- A Koki or Pen
- Duct Tape
- Ruler
- Screw Driver
- Old T-Shirts
- 4 Buckets with Lids
- Cutter Knife
- Sand like river sand. Must not be clay or thick sand.

How you make it
Prepare the bucket No 2
Use the screw driver to make a few holes into the bottom of bucket No 2. The small holes will slow the flow of the water.
Cut a hole into the bottom and a bigger hole into the lid of bucket No 3
Cut a hole into the lid of bucket No 4
Cut up 3 old t-shirts
Collect and wash filter materials
Collect the filter materials. Wash them separately until the water comes out clean. The sand used needs to be similar to river sand (not clay or thick sand).
Prepare bucket No 3 with filter materials
Take bucket 3. Place the cut T-Shirt inside and add washed charcoal. Tie up the charcoal in the T-Shirt and turn upside down so that the knot is facing down. Repeat with sand and gravel. Around half of the bucket should be filled with charcoal and the other half equally with sand and gravel.
How to use it
Assemble the filtration system and filter your water
