the gorkha megaquake water and santiation
TRANSCRIPT
• The innovative part is;
provision of safe drinking water with the safe toilet facility in the schools of earthquake affected districts using simple engineering solution…
• The volume of monthly rainfall excess generated from the roof catchment was estimated using following rational approach of estimation:
• V = (P x A x C)/ 1000• where;• V= Monthly volume of harvested rainfall in m3
• P = Monthly rainfall amount in mm at P ≥ 80% (mm)
• A= Roof area (m2) • C= Runoff coefficient
STORAGE TANKS
•FERROCEMENT TANKS
•Thin, light and easy to transport•Skilled manpower not required•High degree of impermeability and resistance of cracking•Economical
END USES..
Water from the Ferro cement tank
Drinking and cooking in the school andWater from the Ordinary tank
For sanitation purposes in the school
Sanitation
•Toilet that we are going to use is double pit VIP latrine with ventilation.
•Easy to construct.•Can be reused.•The pit and septic tank are separable.
IMPACTSUnusual and unsafe handling of water from the tank in school also can be the reason of platform for the communicable diseases.❖Some what it can be controlled by using
long necked utensils for pouring the water.❖Different trainings can be provided to the
school students for safe handling of water.
