All wells regardless of the use should be sterilized on completion to prevent or retard the growth of corrosion or incrustation fostering organisms. This should be done by introducing chlorine into the water in the well and immediate aquifer surrounding the well .The volume of water in the screen and casing should be estimated and sufficient chlorine added to yield for water with chlorination of 1000 ppm. The solution should be poured into the well and thoroughly mixed in the well by surging with pump. The solution should remain in the well for at leaset 6 hours during which it should be surged at about 2 h interval.
