The WASH+E program includes 10 household subsystems that extend the utility of an off-grid basic dwelling in the developing world.
These household systems are easily enacted with nominal cost. Two of the WASH+E systems use solar energy passively for water heating and actively for basic power needs. The ten systems that are currently being enacted, tested and perfected in several countries include:
- Water Harvesting
- GSAP Microflush Toilet
- Potable Water Purification
- Solar DHW (for preheat cooking)
- Male Urinal
- Shower
- Greywater processing
- Edible Garden
- Lighting & Charging
- Solar Cooker

Why WASH+E?
“There is an imperative today to foster sustainable development. This vision must aim to end poverty, promote prosperity and people’s well-being while protecting the environment. The MDG want to have these in place globally by 2030.” – UN Millenium Development Goals
WASH+E includes several sustainable household systems that support achievement of this goal.
Where is WASH+E Being Implemented?
WASH+E systems are currently being used and monitored/tested in Haiti, Kenya and Ghana.

What is the SDG6?

“Water scarcity affects more than 40 percent of people around the world, an alarming figure that is projected to increase with the rise of global temperatures as a result of climate change. Although 2.1 billion people have gained access to improved water sanitation since 1990, dwindling supplies of safe drinking water is a major problem impacting every continent.
In 2011, 41 countries experienced water stress – 10 of which are close to depleting their supply of renewable freshwater and must now rely on alternative sources. Increasing drought and desertification is already worsening these trends. By 2050, it is projected that at least one in four people will be affected by recurring water shortages.
Ensuring universal access to safe and affordable drinking water for all by 2030 requires we invest in adequate infrastructure, provide sanitation facilities, and encourage hygiene at every level. Protecting and restoring water-related ecosystems such as forests, mountains, wetlands and rivers is essential if we are to mitigate water scarcity. More international cooperation is also needed to encourage water efficiency and support treatment technologies in developing countries.” (read more at the UNDP site).
