  2. Failures of water supply and sanitation systems - Wikipedia

    en.wikipedia.org/wiki/Failures_of_water_supply...

    RWSN (Rural Water Supply Network) estimated in 2010 that only two out of three handpumps are working at any time. [2] Figures collated by the RWSN in 2007 indicate an average rate of 36% non-functionality for hand pumps across 21 countries. This level of failure represents a total investment of between $1.2 and $1.5 billion in the last 20 years ...

  3. Water pumping - Wikipedia

    en.wikipedia.org/wiki/Water_pumping

    Gravity does all the work. In all other instances, pumps are necessary. In day-to-day situations, available water is often contaminated, unhealthy, or even naturally poisonous, so that it is necessary to pump potable water from lower levels to higher levels, where it can be of use. A fresh water source in a lower stream, river, pond, or lake is ...

    Derelict windmill connected to water pump with water storage tank in the foreground. Examining pump repair records and mean time between failures (MTBF) is of great importance to responsible and conscientious pump users. In view of that fact, the preface to the 2006 Pump User's Handbook alludes to "pump failure" statistics.

  5. Pumping station - Wikipedia

    en.wikipedia.org/wiki/Pumping_station

    Typically, water is channeled from a high-level reservoir to a low-level reservoir, through turbine generators that generate electricity. This is done when the station is required to generate power. During low-demand periods, such as overnight, the generators are reversed to become pumps that move the water back up to the top reservoir.

    As of 2017, the New Orleans pumping system - operated by the Sewerage and Water Board - can pump water out of the city at a rate of more than 45,000 cubic feet (1,300 m 3) per second. [1] [2] The capacity is also frequently described as 1 inch (2.5 cm) in the first hour of rainfall followed by 0.5 inches (1.3 cm) per hour afterward. [2]

  7. Hand pump - Wikipedia

    en.wikipedia.org/wiki/Hand_pump

    In parts of Britain and Ireland, it was often called the parish pump. Though such community pumps are no longer common, people still used the expression parish pump to describe a place or forum where matters of local interest are discussed. [3] Because water from pitcher pumps is drawn directly from the soil, it is more prone to contamination.

  8. Water hammer - Wikipedia

    en.wikipedia.org/wiki/Water_hammer

    The water hammer principle can be used to create a simple water pump called a hydraulic ram. Leaks can sometimes be detected using water hammer. Enclosed air pockets can be detected in pipelines. The water hammer from a liquid jet created by a collapsing microcavity is studied for potential applications noninvasive transdermal drug delivery. [33]

  9. Water tower - Wikipedia

    en.wikipedia.org/wiki/Water_tower

    Alternatives to water towers are simple pumps mounted on top of the water pipes to increase the water pressure. [39] This new approach is more straightforward, but also more subject to potential public health risks; if the pumps fail, then loss of water pressure may result in entry of contaminants into the water system.
