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?
