OUTLINES OF THE PRESENTATION• Introduction• Challenges of Re-construction in Working Districts• Data for the Vulnerable Ranking• Methods• Results and Discussion• Conclusions
General:• More than 8000 people were died and more than 22,000 people were injured• More than 600,000 houses were destroyed and more than 300,000 houses were
damaged • 14 districts were severally affected earthquake• Disconnected from basic services: Safe Drinking Water and Sanitation
Impact of Earthquake on the Drinking Water and Sanitation:• Water schemes: Total 11,288 (Complete destroyed 1,570 & Partial destroyed 3,663)• Nearly 2.2 million Household latrines were totally destroyed• Lack of water and destroyed latrines: Affected to hygiene practices• Affected on water availability: Reduced water yield, Lost of sources, Contamination due
to damaged of infrastructure and landslides
INTRODUCTION
CHALLENGES IN WORKING DISTRICTSChallenges of Reconstruction and Study Area (Working Districts):
• Prioritization of working area and Village Development Committees (VDCs)
• Prioritization of vulnerable communities
4 Working Districts:• Dhading: 47 VDCs• Gorkha: 62 VDCs• Nuwakot: 62 VDCs• Rasuwa: 18 VDCs
DATA FOR THE VULNERABLE RANKING
Three Major Community Level Parameters and Indicators:
1) Number of households without safe drinking water after the earthquakes
2) Number of households without improved sanitation after the earthquakes
3) Disadvantage Group (DAG) Ranking of the VDCs

• The technique was based on the damage of Water and Sanitation infrastructures, people excess to basic services, and socio-economic status within the VDCs and Districts
• Small exercise, but very useful technique to make the important decision to categorize vulnerable communities
• The technique was found socially and scientifically justifiable among the stakeholders and donor
• Considering community level parameter and indicators in the technique is a strength of decision making to select the working VDCs
• The technique was applied to reach out the re-construction activities to the relatively higher vulnerable communities/VDCs
