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…

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.)

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)

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

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

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

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

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
