One in five children in Cambodia die due to water borne diseases. We're building a tribe of passionate individuals who are ready to step up and help. Join us in bringing clean water to rural Cambodia.

Our Next Trip: 19 to 22 December 2018


The Experience



Start by launching a personal fundraising campaign to raise money for life saving water filters. When you raise at least USD 300 you will immediately qualify for our upcoming group volunteer trip to Cambodia.

Travel with us to Siem Reap for an unforgettable experience. Get your hands dirty building and installing BioSand water filters. You will also get to meet and interact with the rural families your efforts are helping.




Over 100 #MADVolunteers have already supported more than 1000 families in rural Cambodia gain access to clean drinking water.


Mothers, daughters, 70 year olds, 10 year olds, corporate high-flyers, freelancers, students and home makers. #MADVolunteers come from all walks of life but are unified by their commitment to make a difference in the world.

Thanks for organizing such a great volunteer trip. Definitely very memorable and I look forward to joining you on the next one!

Raising funds for the filters was easy (Malaysians are a generous lot!) and the trip to Siem Reap to construct and install them was amazing!

Being on the ground opened me up to the realities of poverty which I would have never truly understood otherwise. Great trip organized by MAD!

The Impact

dirty water, clean water

The Problem

Cambodia is one of Southeast Asia's poorest countries where over 50% of rural Cambodians do not have access to safe drinking water or adequate sanitation. Children are especially vulnerable to water borne diseases because their bodies are too weak to fight off diarrhea, dysentery and other illnesses. 

MAD Filter

The Solution

A BioSand Filter (BSF) is a household level water filter that uses age old sand filtration technology to clean surface level water (pond / river water). Each filter is capable of removing up to 98.5% of bacteria and 90-95% of iron  from the water. Each filter provides safe and clean water for the needs of one family and can last for 15 years.

We have been working with local nonprofit Water For Cambodia (WFC) since 2013. To date, WFC has installed over 20,000 biosand water filters across rural Cambodia which has helped over 120,000 people gain access to clean drinking water. Their method and dedication to sustainable impact have positioned them as a globally recognised leader in BioSand water filter installations.
