Maintenance is limited, and consist mainly of repairing the rope or handle. Evaluations show that rope pumps on communal wells can be maintained by the users under certain conditions. One of the main conditions is a very high level of community coherence and responsibility. If the rope pump technology is introduced properly, like often is the case with the Zimbabwe Elephant Rope pump, up to 90% of rope pumps remain operational, even after many years.

Most common diesel and petrol pumps are suction pumps that can pump from shallow wells down to 7 m. deep. Pumping from deeper wells requires generator pump sets or long-shaft diesel pumps costing US$ 800 or more. Where there is electricity, submersible pumps can be used but many small farmers do not have electricity.
* Cost of introduction: between US$ 10,000-30,000 per project, including 20 pumps, engineering and hands-on training.
* Rural water programme: US$ 150,000-200,000 per project, including 1,000 pumps, start up of production facility and hands-on training.
