Stage 5: Scaling
Ethiopian government policy promotes R & W pumps. Donors support R & W pumps, including for WASH. ILSSI cost-benefit on scaling suggests R & W can improve yield and income, but do not reduce labor required significantly; impact is constrained.

Water Management, Agriculture, Climate Change and Resilience and NutritionSEE LESS
Limited ability to improve income, nutrition, resilience in rainfed areas. Need to introduce dry season and supplemental irrigation. Technology needed for water lifting and improved water resources management while reducing labor requirements.
Low cost, shallow groundwater lifting technology that moderately reduces time required for abstraction of water for irrigation and domestic needs, such as WASH.
Farmers at the household level
The modern Rope and washer pump is a highly efficient and low-cost pump, it can be produced with local materials and can be truly operated and maintained at a village level. The basic design has a wheel with a continuous loop of rope with pistons that fit with a small clearance in the pump pipe. The low end of this pipe is at the bottom of the well. By turning the wheel, the rope passes up through the PVC pump pipe and pushes the water up. At the top end of the pump pipe, the diameter increases and the water comes out via a Tee piece. They can pump water from up to 25 meters underground.
Moderate improvement over buckets and watering cans for irrigation of small plots and high value horticulture crops. Cost effective, can be produced and repaired locally (with training) for maintenance.
Planned Goals and Milestones
No scaling anticipated; most farmers do not prefer the R & W pump over other mechanized options.
The Team Behind the Innovation
ILSSI collaborates with international CGIAR Centers, including IWMI, ILRI and IFPRI, as well as national partner universities and agriculture research institutes, which include linkages with extension and farmers. We also have a network of private sector technology suppliers. This integrated partnerships allows us to access expertise from all regions of the world, across numerous disciplines - and supports innovative methods and field work.
