The toilet is a compact, waterless toilet built around sealable containers that enable easy and hygienic removal of the waste. The feces are captured in a 20 l container, the urine is either stored in a bottle or piped into a small soak-pit. Feces are covered with dry material (in Haiti, a mixture of crushed peanut shells and sugar-cane bagasse) after each use. The whole unit is self-contained for easy movement or transport, and for stability on the often uneven floors of homes in informal settlements. The toilet is designed to cater to the aspirations of the customers, which is for a modern, hygienic, and pleasant experience. The toilets were designed in conjunction with an innovative service where full containers are sealed, removed, and replaced with clean ones by uniformed, professional staff. The waste containers are transported to a waste-processing site for conversion into safe, valuable fertilizer. The combination of the toilet with low monthly subscriptions for waste collection provides flexibility that is critical for many residents of urban slums. This was a collaborative effort between re.source (www.resourcesanitation.com) and SOIL (www.oursoil.org).
Target areas are regions that have little or no piped water or sewer infrastructure, and limited roads. In these conditions, approaches focused on public toilets and private pit latrines are unlikely to deliver complete, lasting, or effective sanitation. Residents in dense urban settlements need compact, low-cost toilets that provide flexibility, mobility, and low investment risk while facilitating easy, sanitary emptying. These communities are often informal settlements, where residents are often evicted on short notice. The portable household toilet has no big up-front purchase cost and is portable so it can move with the customers, or the service provider can recover it. The toilet is also useful in emergency and refugee situations.
Each household pays a monthly subscription fee of 5 USD, which includes financing the purchase of the toilet itself, and the waste collection service. This subscription fee is on par with the amount of money households in the community typically spend on cell phone communications.
