Simple Technology of Shallow Wells
Provision of clean and safe water to all people is a major preoccupation of governments of developing countries. Owing to limited resources some countries have opted for the simple technology of shallow wells particularly for rural water supply schemes. One such country is Tanzania where shallow wells have now been in use for over 10 years.
It is shown from Tanzania's experience that shallow wells are much cheaper to construct than any of the alternative systems. Two types of shallow well are in use, namely the hand-dug and the handdrilled well with the latter preferred in high yielding aquifers. The characteristic problem of a shallow well is its relatively limited yield. Hand pumps fitted on some of the wells pose serious problems at times due to frequent breakdowns.
Results of some of the shallow well programmes have shown that investigations prior to sinking of a well are important. The villagers should be fully involved in the shallow well programmes. Countries should share their knowledge of shallow well technology. Indeed shallow wells will become increasingly important in developing countries especially during the test period of the International Water and Sanitation Decade.
