Engineers Without Borders Australia does something most people don't think about when they hear "water charity" — they solve the difficult engineering problems that stop basic sanitation from working in the first place. Think: communities that flood every wet season. Floating villages. Areas with solid rock beneath the surface. Places where the standard toilet design simply doesn't work.
Who Are They?
Engineers Without Borders Australia is a humanitarian organisation using engineering to improve lives in disadvantaged communities across Cambodia, Timor-Leste, Vanuatu, and Australia. They work toward UN Sustainable Development Goal 6 — clean water and sanitation for all — with a focus on communities most left behind.
EWB's approach is community-led and capacity-building focused. They don't parachute in with a pre-designed solution. They work alongside local engineers, governments, and communities, training local practitioners so knowledge stays when the volunteers go home.
The Sanitation in Challenging Environments (SCE) Program
Here's the problem EWB addresses that most people don't know about: even when sanitation systems exist, they often don't work in "challenging environments" — areas that flood seasonally, have very high groundwater, very hard ground, or experience long droughts. Standard toilet designs fail in these conditions, leaving some of the most vulnerable communities without workable solutions.
EWB's Sanitation in Challenging Environments program, running in Cambodia since 2008, tackles this directly. They develop and test toilet designs that work in these conditions — raised platforms for flood-prone areas, systems for floating villages, designs that cope with hard-pan soils. It's genuinely innovative engineering in service of a very basic human need.
The Work on the Ground
EWB's in-country staff, Field Professional volunteers, and local partners work directly with communities to design, build, and commission WASH systems. One volunteer described the experience: working alongside an incredible team of Cambodian engineers going into communities and designing and building toilets for individual families to use right now.
This community-embedded approach means solutions are practical, maintained, and owned by the people using them — not dependent on ongoing outside support.
University Challenge & Professional Programs
EWB also runs a university challenge program engaging engineering students across Australia and New Zealand to develop community-centred design solutions, and immersive programs that let professionals work directly in partner communities.
Why This Matters
Poor sanitation isn't just uncomfortable — it's deadly. Diseases spread when faecal waste isn't properly managed. Children, especially girls, drop out of school when there are no proper toilets. Communities can't thrive when members are chronically ill from preventable waterborne diseases. EWB's engineering focus addresses the root infrastructure problems that other interventions can't easily reach.
💧 A Note on Gratitude: About 3.6 billion people — almost half the world — don't have access to safe sanitation. The work EWB does is about giving everyone the basic dignity we take for granted.
How to Get Involved
EWB Australia welcomes volunteers, donors, and corporate partners. Engineers, non-engineers, and students are all welcome — the programs need people with all kinds of skills. Visit ewb.org.au to learn more about volunteering and donating.
