Maintenance of borewell used for rainwater harvesting purposes in a house in Bhopal, MP - Can bleaching powder be used to clean and de-worm?

I recently read in a local newspaper that before the onset of the monsoon it is advisable that a kilogram of bleaching powder is added to the borewell which is used for Rain Water Harvesting purposes. The role of tbe bleaching powder is to act as "a cleaning and de-wroming agent". 

Is this recommended by the experts on this forum? Is there a set of rules or a fixed routine for performing maintenance for a borewell.
