Operation and Maintenance
Water Resources Management. Failure of a pipe or valve in a water distribution system causes service disruption and other inconveniences to the customers at or downstream of the failure location. To minimize the impact of such a pipe or valve failure, it is crucial to identify those pipes or valves whose failure will have the most severe consequences in degrading the performance of the system relative to that of other pipes or valves. In this paper, we develop two failure analysis methodologies, Pipe-by-Pipe and Valve-by-Valve, to prioritize the importance of pipes and valves in a water distribution system. The relative importance of individual pipes and valves is evaluated according to the number of customers who are forced out of service as a consequence of a pipe or valve failure.

Generally, water and sanitation projects experience their most serious problems with operation and maintenance and with cost recovery aspects. Therefore, it is imperative to plan for operation and maintenance, with a planned withdrawal of external support as local ownership builds. This document is intended for managers and planners who are concerned with the challenging problem of how to implement effective operation and maintenance in water and sanitation projects. Operation and maintenance is a crucial element of sustainability, and a frequent cause of failure of water supply and sanitation service facilities in the past. Many failures are not technical ones. They may result from poor planning, inadequate cost recovery, or the outreach inadequacies of centralised agencies DFID Operation and maintenance has been neglected in the past, or been discussed and introduced only after a project was completed.
