2. Introduction
a large flow of water falling through a
small head, to lift a small flow of water
through a higher head.
The main virtue of the hydram is that its only moving parts
are two valves, and it is therefore mechanically very simple.
• A hydram is an automatic pumping
device which uses…

4. Potential applications
• Household water supply and sanitation (Can serve a single house
or a medium size community)
• Irrigation (small – medium scale) – more likely for cash crops
(vegetables, fruit trees, etc.)
•Supporting livelihoods (eg. Cattle rearing, fishponds, lemongrass
tea production, etc.)

5. CRT/N and Hydraulic Ram Pump
• CRT/N has Implemented 12 Hydrams
• 3 units in Ramechhap district with support from SARI/E, USAID
• 4 units in Dhading district with support from Renewable world
,UK
• 5 units in Far west ( Dadeldhura, Achham, Baitadi and Doti)

6. Impact of HYDRAM
On hygiene and Sanitation
 Project: Mahadevsthan Hydram project
 Implemented on Pipal Bhanjyang HSS
 584 students and 16 teachers are
benifited
 Female student presence rate
increased
 Health issues is solved
 School and its surrounding’s
environment is clean and healthy

7. Impact of HYDRAM
HHs level DWS
• Salyantar and Sunaula bazaar DWS
projects
• Lifted water to 150m of vertical
height and save the time of 60
HHs to fetch water
• 6 hrs a day per HHs has saved
• Reduced drudgery of housewife
and female children
• Children can go to school regularly
• Improve health and sanitation

8. Impact of HYDRAM
• Micro irrigation
• Project: Muralibhanjyang hydram
micro-irrigation project
• Facilitated wider range of
vegetable production increasing
household incomes
• Off season crop are promoted
• Reduced the conventional way of
cropping pattern

9. Learning
• The complex socio-cultural, geo-political and socio-economic
factors affecting water resources and sanitation management
in low-income and middle-income society
• Community contribution is key factor for sustainable project
run
• MUS project and endues diversified project last for long
period

10. Mountain, Irrigation, Water supply and Sanitation
– Isolated and scattered villages/households
• Water supply investments are high
• Access to energy is problematic
– availability,
– Reliability
• Thus electric pump are not a reliable option
– High inbound and outbound logistic
• Conventional fuels are expensive
• Erratic supply of inputs
• Spare parts based technology are problematic
– Economy is not monetized
• Ability to pay cash /Poor in terms of cash availability
• Cash flow is not stable and regular
– Problem in regular fee payment
