Protocol for the punctual chlorination of a hand dug well, either:

  • at installation, as a routine procedure for its first use,
  • for disinfection when bacteriological* analysis show a contamination - we call it ''shock chlorination'' when the treatment required curing and cleaning the wall of the well.

the manual explains how to calculate the dosage according to the depht of the well.
