Introduction: Purifying Water During Natural Disasters
The design idea is to create an environmentally, socially, and financially sustainable solution to providing clean and drinkable water during a natural disaster. "El Huaico" is a solar evaporator currently designed to help the rural population affected by El Niño Phenomen 2017 in Peru.
It has the flexibility to be used with any container, is durable, easy-to-use and maintain. It consists of easy to assemble modules: plastic bottles, cardboard boxes, flexible tubes, strings, electric copper wires.
Its design allows solar evaporation of dirty/raw water and condensation of clean/distilled water, stored in plastic bottles filled with copper wires.
Its a simple process, the sun heat the water to the point where it evaporates then the water vapor is captured and cooled, allowing it to condense back to water. Copper generates free-radical ions which quickly kill microbial pathogens.
Conventional water-treatment methods such as chlorination, filtration and energy-intensive (UV, Reverse Osmosis) are impractical in rural areas, urban slums and natural disasters scenarios.
Huaico is a Peruvian term that refers to a massive flood caused by torrential rains during extreme weather events.
Step 1: Materials and Tools
- Real natural disaster scenario
- Limited sources of materials and tools
- No drinkable water
- Best source of fresh water is rain
- Rivers and lakes with very high turbidity levels
- Available sources of energy: sunlight, wind, human
- No telecommunications or very limited
- No transportation, most freeways and bridges destroyed or with severe damages
- Electric boiling: No electric power and electric grids destroyed or with severe damages
- Gas or Oil boiling: gas and oil unavailable
- Chlorine and pills: Very limited distributions and in most areas unavailable
Selected available materials and tools:
- 2 Plastic Water Bottles
- 1 Cardboard Box (Thermal Insulator)
- 1 Flexible Tube (~1 - 2 cm diameter)
- 1 Electric Copper Wire (~40cm long) (Antibacterial)
- 1 String
- Knife or Cutter
Step 2: Assembling
Easy and simple steps
Step 3: Testing: El Niño Phenomen 2017 in Peru
Huaico is used in a real natural disaster scenario!

Work in progress:
- Version 2.0
- Emergency Kit
Emergency caused by heavy rains, overflowing rivers, landslides and floods battering Peru has so far left 159,283 victims, National Emergency Operations Center's (COEN) latest report revealed on Friday 4/7/2017.
Likewise, natural disasters have affected close to one million people (973,977).
Damaged homes stand at 212,966.
Death toll remains at 106, according to COEN's document.
Step 4: Version 2.0
- New cardboard enclosure
- Flexible tube diameter 1cm to 2cm
- Inclination 45 degrees
- Optional: Reflective surface (Aluminium foil)
- Optional: Painting the bottle with black paint.
We have a be nice policy.
