Hi Etienne,
It is not very easy to know the quantity of water in the well, the Chlorine/Hypochlorite-based treatable contaminants and the amount of disinfectant (Chlorine, Sodium Hypochlorite, etc) required for efficient and safe treatment.
I therefore suggest 2 ways; (1). Extracting the water and treating it (prior to bacteriological and physicochemical analysis of the raw water to know the contaminants and if Chlorine is the appropriate disinfectant). (2). Installing the appropriate disinfectant dispenser near the wells, so that those who fetch and use the well water will take an appropriate quantity of disinfectant into their water containers before fetching the raw well water so it mixes well to disinfect the unsafe well water before they use it ( this may need simple monitoring and teaching).
You can fill the disinfectant dispenser or treat the extracted raw water with our SaferEx - Multi-action Water Purifier that disinfects, coagulates and sediments heavy metals and particles, among other things in a single application and unit process, (https://thewaternetwork.com/_/saferex-multi-action-water-purifier-a-solution-to-water-challenges/blog-Jl6/saferex-multi-action-water-purifier-a-solution-to-water-challenges-4sjP18jNM71wltS8grBy-Q)
