The CPT (Comissão Pastoral da Terra de Caitité-- Church
Commission of Caitité) offers farm workers (with manual skills) courses in
The PVC used is rigid, welded together and has a diameter of
160 and 110 mm. This material is excellent to make hand pumps for the following
It is easy availability in the markets;
Easy modeling at a low temperature;
No need for sophisticated equipment;
Besides PVC tubes, one only needs wood, leather, screws and glue.
Since they have participated in these courses, farm workers
in some counties are now building these pumps for their own use or to sell.
The results of using the pumps are satisfactory. When used
on the ground, the pumps are capable of pumping 3,200 liters/hour. From a
height of about 8 m the pumping capacity drops to 1,500 liters/hour. The
maximum sucking limit is up to 6 meters, and we already succeeded in pumping
water for about 300 m. The PVC- hand pump is used to take water from cisterns
and holes and to pump water from wells into other containers to be used in the
house as well as for animals, or to water small garden areas. In our region100
pumps are currently in use. There use is limited due to the limited financial
resources of farm workers, after all a PVC pump costs between R$ 90 to R$ 100
(US$ 54 to 60).
