WaterAid Ghana’s Rope Pump
Activities
Presented by: Jesse Coffie Danku
Head of Programmes
Introduction
• WaterAid’s vision is of a world where everyone has access to safe
water, sanitation and hygiene services
• WaterAid’s mission is to transform the lives of poor people without
water and sanitation by working with and influencing others to deliver
these services equitably and sustainably
• WaterAid, as an implementation strategy, uses model projects to
influence big sector players, e.g the rope pump
• Value based methodologies are used to model projects
•
•
relative advantage model project will produce in sector
Create stairway of innovation
• Rope Pump technology is one such model project
• It is a low cost, simple and easy to maintain handpump that can be
made with locally available materials.
• The technology is useful in domestic and community domestic water
supply as well as in the field of small scale agriculture.
• Operates effectively on hand dug wells and tube wells to a maximum
depth of 30m

Processes (Steps)
• Determine the value curve
• Compare relative value model will add to sector with value
existing system(s) are providing
• Generate key elements of models by considering ff questions
• What factors should be raised beyond sector standard
• What factors should be created that the sector has never
offered
• What factors should be reduced well below the sector
standards
• What factor should be eliminated that the sector has taken
for granted
• This has to be done in a brainstorming session
• Once the key elements of value have been generated a
comparison can be done by rating each of the elements.

The Journey so far
• Determined key elements of
rope pump
• Developed concept paper on
rope pump promotion
• Organised sector
brainstorming
• National taskforce formed to
follow up on technology
• On-going implementation of
technology in three northern
regions
• Documentation
