Hand dug wells may need repairing, cleaning and disinfecting after inundation by flood water, inundation of seawater as in the case of a tsunami, materials entering as the result of mudslides or as a result of hurricanes, or simply after long periods of limited maintenance or neglect. If work has been undertaken on the well to try to increase its yield through, widening or lining the well, then cleaning and / or disinfection will also be appropriate. This Technical Brief identifies the process for repairing, cleaning and disinfecting hand dug wells and also discusses the OXFAM kits which can be used for these processes.
