Safety

• Cover the pit with a grate — fall hazard
• Mark the site clearly
• Only use a food-safe jug for collection

How to put it together

1. 1

   Pick the site

   Choose a shaded hillside or cool hollow with humid nights and decent drainage. Avoid flood paths and septic areas.

2. 2

   Dig the pit

   Excavate a cone or bowl ~1–1.5 m deep and ~1–1.5 m wide at the top. Slope walls so stones can stack stably.

3. 3

   Lay gravel base

   Put a gravel layer at the bottom for drainage. Place the food-safe jug or collection vessel at the lowest point with a clean fill path.

4. 4

   Stack stone mass

   Fill with loose stone/rubble leaving air gaps. Cool stones are the condensation surface — do not pack airtight with mud.

5. 5

   Air path

   Leave a deliberate cool-air intake (gap or chimney pipe) so moist night air can flow through the stone mass.

6. 6

   Cover safely

   Add a strong mesh/grate cover that still allows airflow. Keep children and animals out.

7. 7

   Collect & observe

   Check the jug each morning in humid seasons. Yield varies strongly with humidity — log results for a week.

Tips

• Works best on humid nights, not dry desert afternoons
• Bigger cold stone mass → more condensation surface
• Keep organic dirt out of the jug path
