__NOTOC__
Because of their lightweight and low-cost design, PVC pumps are mainly suitable to be used by families or small groups of families. PVC pumps are not recommended for use by large groups of people, as this will lead to the need of frequent maintenance. An excellent overview of community hand pumps, which are suitable for larger groups, is available at the RWSN website<ref>[http://www.rwsn.ch/prarticle.2005-10-25.9856177177/prarticle.2005-10-26.2582788867/prarticle.2008-12-04.2105225472 Overview of community handpumps at the RWSN website]</ref>.
These pumps are very popular for domestic use, as shown by 20,000 water systems in Bolivia, which are made with locally available PVC tubing and valves made with marbles. PVC pumps are used in Malawi and Brazil and many other countries in combination with water storage tanks, for example in the kitchen. When used with a storage tank near the roof in a kitchen, running water becomes available in the kitchen, often considered a great luxury.
Because the water is pumped immediately to the storage tank without intermediate handling, the quality of the water remains good and the risk or recontamination is greatly reduced.
