An Analysis of Scale and Technology in Rope Pump Piston Manufacture and Supply in Sub Saharan Africa
1. An Analysis of Scale and Technology in Rope Pump Piston Manufacture and Supply in Sub-Saharan Africa Donald J. MacAllister, Cranfield University, UK Dr. Brian S. McIntosh, International WaterCentre, Australia Erik Harvey, WaterAid UK
10. Low density areas may require subsidyHarvey, P.A., & Reed, R. 2006 Sustainable supply chains for rural water supplies in Africa. Proceedings of the Institute of Civil Engineers, Eng. Sus.159(ES1), pg.3139 Scale and Technology in Rope Pump Piston Supply
11. Study objectives Quantify the number of rope-pumps installed, and characterise rope-pump and piston failure Assess manufacturing quantity (volume) required for, and costs incurred at break-even Assess the minimum pump densities required to achieve break-even To make recommendations regarding the creation of sustainable supply chains with existing pump densities Scale and Technology in Rope Pump Piston Supply
22. Supply implications 1 – pistons or pumps? b) 15 pumps within 40km a) 682 pumps within 40km Illustration of the SDB in rope-pump supply for Ghana. For sale of single pistons, For sale of multiple pistons with rope. Note pump locations do not indicate actual pump locations Scale and Technology in Rope Pump Piston Supply
