Access to quality, affordable latrines is crucial for disease prevention and sanitation in developing countries. Without them, community health and development suffer. Unfortunately, the most commonly used toilets globally—pit latrines—pose problems related to affordability, maintenance, and waste disposal. While the common pit latrine is a simple technology, it is not necessarily inexpensive. Pit latrines are often difficult to maintain over time because the pits fill with waste and the pit walls collapse, rendering the pit unusable.
Recognizing the need for sustainable, affordable latrines as a vital step in alleviating poverty, Design Outreach has assembled a team of experts in project management, engineering, human factors design, sanitation, soil mechanics, and polymer manufacturing. They are working together to determine how to create a pit liner and floor slab that are affordable for a single family, will keep pit walls from collapsing, and can be reused.
In 2021, the team completed critical initial research into the challenge of constructing pit latrines, studied and evaluated available solutions, and began developing new concepts now being tested. LifeLatrine™ is a sustainable, affordable solution to support improved sanitation and hygiene in developing countries.
