2. Electric pump systems - Problem
• Rural water supply systems are relatively easy to construct, but more difficult to manage effectively.
• Systems which include electrical pumping are particularly vulnerable to failure and long periods of down-time.
• Pumped systems are increasing in number as most springs and surface water sources have now been developed.

Learned
• Understanding how many systems, functionality
and failure modes important
• Accepting the need for more human resources
and budgeting realistically
• Advocating for the long term benefits of
investment in O&M
• Evidence based decisions key
