The Consallen deepwell pump shown here is one of a number installed in Haiti by a US Christian Charity as part of a community programme to improve the water quality available to villagers.

The pump is set on a borehole drilled about 35 metres deep, and serves a community and the church. The pump deliveres about 20 litres per minute, and roughly 5-6,000 litres a day.

The pump was installed in 2003, and is supplied with spares as required by mail order, and the average cost of the pumps in this group is GBP £7.70 a year for the last 6 years.
