How does the technology work? Is it a centralized or decentralized solution? Would the system still be connected to existing the wastewater treatment system?

Safe disposal of human excrement

INTRO
In this module, students will research three options for sanitation that allows for safe disposal of human excrement, but do not rely on water-based flushing. These may be systems that are decentralized or connected to centralized treatment.

ACTIVITY
Put together a document that summarizes the finding of your research by addressing the following questions for each of the three alternatives you identify:
• How does the technology work? Is it a centralized or decentralized solution? Would the system still be connected to existing the wastewater treatment system?
• If available, what would the approximate cost be of installing this type of system?
• Has the technology been successfully deployed? Can you find case studies or examples of the system operating under realistic conditions?
• Is the technology suited to large-scale implementation? (for example on a dense college campus or large buildings)
• What are the major benefits of this technology from a resource management perspective? Are there any useful byproducts from this particular strategy?
• Does it have drawbacks that might be concerning?
• What challenges might you anticipate with deploying an alternative like this?What might the various stakeholders in the use of water-based flush toilets and wastewater treatment think about this option?
