To evaluate the functionality of Rope pump To determine the water quality of water pumped up by Rope
pumps especially regarding fecal contamination
To get an impression of the social and economic impact of Rope
pumps both for Communal supply as well as Self supply
To get information on bottle necks and interest by government
and NGOs to use this technology in their water programs

As the average borehole depth reduces the Coliform count
increases per water sample

Willingness to repair the Rope pump
Communal water points
Despite majority satisfied with the technology, only 11% of respondents
had already started repairing
44% of respondents were doing nothing about repairing the Rope
pump. Private water points
Respondents willing to repair despite having alternative sources
(piped water into dwelling)
2 respondents (28%) willing to repair but couldn’t get in touch with
technician
Socio-economic benefits
1.
Increase access to improved water & sanitation Moving from unprotected wells to protected water source
Used for irrigation Domestic animals
Installation costs lower as compared to other technologies Affordable maintenance costs Affordable spare parts Save money from excessive water bills
easy to maintain
Easy to operate
women fixing the pump
Children operate without hustle
Simple to maintain
Reliable source of water
Water every time all year. No disconnections & 87% of respondents access water at every time of the year as long as the
Rope pump is functional
NGO’s
investment cost is low. Local communities can afford
Greater proportion of rural population still use unprotected sources. Rope pumps can help cover gaps
categorized Rope pumps with shallow well (which the government can
not accept)
Govt policies doesn’t accept Rope pumps (shallow wells). Unless substantiated with water quality results, govt feels the technology
is prone to contamination.
Unable to serve larger communities The technology looks like a temporally solution No plans to promote but support organizations to supply in very needy
areas where
A need to Train users on O&M A self-supply approach regular or periodical monitoring of water points Involvement of government in rope pump technology as key player Dissemination of info in key conference in conjunction with other WASH
players
Need for improvement ( design & method of drilling) to address water
quality concerns
