Is treatment of drilling water used in production process required?

It is not mandatory

not in case of municipal or well water, only you have to ensure once per year that the water is clean by external laboratory

 

Good evening,

 

I have a small problem: we are carrying out a danger analysis for a date factory and we use the drilling water as process water in this case is a treatment is mandatory for this type of water ( by chloration or UV) to guarantee the bacteriological quality of the water.

 

And in the case of use of treated public water (the microbiological quality has been proven satisfactory after analysis) water treatment (by chloration or UV) is it mandatory or not?

 

It depends initially on the physical/chemical/bacteriological analysis of the water supply on reception and at source.

However IMEX (not dates) chlorination is typically routinely applied at reception after filtration. Unless Regulatory unallowed.

either way, this doesn't cover what happens to water WITHIN your facility 

You still need to sample within the establishment for potability on a rotating schedule of locations

It is not mandatory

not in case of municipal or well water, only you have to ensure once per year that the water is clean by external laboratory

I have to prove the potability of water

and  the  well  water   is  not  potable
