Community level lift motorized pumps


Mostly a sealed electric motor attached to a centrifugal or progressive cavity pump, submerged into the water body. Also possible with a motor installed at the surface. It is self-priming, if not run dry. Mainly used with electricity (from mains), solar power or a generator. Can lift water from deep boreholes (< 6000m).


A submersible pump might cost USD 2000-7000. In addition, installation costs for solar panels or connection costs to the electrical power system may apply. Running costs mainly dependent on power source. Solar systems occasionally have high component replacement costs.


Both installation and maintenance require professional technical skills. Proper training for operation is required. Organization is required for fee collection to cover considerable operational and repair costs. Management can be either responsibility of local committee, municipality or a private operator.


Large volumes of water can be pumped, might result in depletion of the aquifer. Can also negatively impact yield of surrounding wells. Possibility to pump from large depths makes it suitable for arid and drought-prone areas. Little risk of water contamination.


High-tech option requiring limited maintenance. Requires water level monitoring to prevent pump from running dry. Occasional tasks: checking valve and cables, replacing fuse, pipes and pump stages. Engine requires conventional maintenance. The driver belt needs regular replacement. Storage is mostly recommended to ease management of operation (buffer for high peaks and periods of non-pumping).


Acceptance level is generally high, thanks to the good operational reliability. The relatively high fees may pose a problem for users. In case of regular power cuts, user disappointment is to be expected. An awareness raising campaign is not necessary.
