Abstract
  • 2.6 billion people lack access to adequate sanitation which contributes to preventable diseases. The purpose of this thesis is to explore the feasibility of and develop specifications and design criteria for a packaging sanitation solution for peri-urban areas. Safe containment of excreta requires the packaging meet a storage period (4 weeks), a storage capacity (tertiary packaging storing 105 bags of individual defecations), gas permeations, odor control, and pathogen containment that were based on expected use and published research. Data from focus groups in Peru regarding preferences and willingness-to-pay (WTP) for sanitation indicated a WTP of $2.16 per month for a pit latrine but $5.42 for a flushing toilet. The proposed specifications are a primary bag that holds the excreta, a secondary bag that lines a tertiary unit, and a tertiary unit that provides the support structure for the user and storage for the used bags until final treatment and disposal.
