A safe, sustained sanitation service well suited to providing services in difficult contexts.

Container Based Sanitation (CBS) is a sustained sanitation service, featuring toilets with containers that are frequently sealed and collected, so that the waste can be safely treated, reused or disposed of.

The main defining feature is this frequent servicing, typically every two weeks to three times per week. In practice there are several technologies for containment, transport and treatment, and several derived products from the waste.

As CBS does not require digging, unlike sewers, pits or septic tanks, it has found a niche in many hard-to- reach or underserved contexts: densely populated informal settlements and refugee or transitional settlements, and areas with rocky ground, high groundwater, droughts, hills or frequent floods.
