<p>A pressurized cannister or sealed vessel is filled with a disinfectant agent, for example chlorine. A discharge jet is either attached to the vessel or to a hose attached to the vessel, and the discharge jet delivers the disinfectant agent evenly throughout the entire body of water within the well casing. In the case of dug wells or shallow wells, the entire vessel is lowered down into the well, the vessel being connected to a pressurized water supply via a hose. With drilled wells or deep wells or deep wells, the disinfectant agent is delivered by means of a discharge jet at the end of a hose connected to the vessel. In this way, it is ensured that the disinfecting agent comes in contact with the entire contents of the well and guarantees that the disinfectant will be drawn into the water intake of the well and into the water supply pipes.</p> |
