Terraclear - Clean water access for families in Laos

  • 3. Good Health
  • 6. Clean Water
  • 13. Climate Action

In Laos, over 80% of households must boil their water to make it safe to drink. Despite many taking this boiling precaution, preventable illness from drinking contaminated water is still a leading cause of death for children under five. But with a water filter at home, families can produce their own safe water every day.

The filters do more than just fend off thirst and illness. Without the need for boiling water, families are able to buy or collect less wood and fossil fuels, reducing smoke in the kitchen, and protecting Laos’ beautiful forests from further deforestation.

TerraClear is breaking down the barriers that make clean water access a challenge for rural communities. Creative strategies and community focused education and promotion are allowing TerraClear to change lives a few liters at a time. TerraClear is providing access to safe drinking water through the manufacture and distribution of more than 33,000 ceramic filters reaching an estimated 150,000 people in over 500 villages in Laos.

Project impacts and benefits

  • 15,000 tonnes of CO2e saved annually by the project
  • 20-30 litres of clean water - the average daily household consumption fully met by each filter
  • 32,000 households benefiting from filter use

For every 1000 carbon credits purchased:

  • $15,800 value of avoided forest degradation*
  • 12 hectares of avoided forest degradation*
  • 25 cases of Acute Lower Respiratory Infection (ALRI) treatment avoided*
