1 Green Recovery And Reconstruction: Training Toolkit For Humanitarian Aid Water and Sanitation Session 2: Environmentally Sustainable Water and Sanitation Technologies

2 2 What’s different between standard watsan and post-disaster watsan? Flooding Indonesia December 2006 Photo Emily Rand

3 3 Key Points Good WatSan = Good Environmental Management Principle: WatSan projects “do no harm” to the environment Goal: Sustainable watsan projects after disasters have humanitarian and environmentally positive outcomes

4 4 What are the criteria for successful watsan projects?  Another way of saying it: What are the conditions that need to be in place for watsan projects to succeed?  List them on a flip chart  E.g.,  Community participation in decision making  Works with cultural norms and practices  Affordable  Appropriate soil and climate conditions  Adequate training in use and maintenance of the system  Others?

5 5 In this session we will discuss….  Key post-disaster watsan technologies  Technologies that are chosen for their sustainability  Disaster or emergency situations when this technology is uniquely applicable  When it is best not applied

6 6 Basic Principle: Don’t Eat Poop Mod 7 Ses 2 Our job is to insert a barrier
