The well shall be disinfected or sterilized as per IS code 2800:2019 or latest, after the development by pump and before the final test. 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. After expiration of contact time , the well should be pumped initially back into the well for abour 30 minute and late to waste until there is little of no odour or taste of chlorine in the discharged water . IT has been found that using hypochlorite is of 10% concentration, the requirement of hypochlorite is 10 litre for every cubic meter of water in the well to produce. |
