In cases where the supply takes place from a non-drinking source, it is first of all necessary to have the water analysed (it is recommended to analyse it over time because the quality can change, and even a lot, at a seasonal level or following heavy rains), in order to know its characteristics and identify its criticalities. Generally, it is not necessary to analyse all the parameters required by the legislation (Legislative Decree 2 February 2001, no. 31 “Implementation of Directive 98/83 / EC relating to the quality of water intended for human consumption”) but it will be sufficient to check its microbiological quality, as well as some metals and other substances that can be potentially present in groundwater.
When you are not connected to the aqueduct network, the procedure to follow to make well water drinkable is, in summary, as follows:
Establishing with the help of the laboratory technician the parameters that need to be analysed.
Identifying the most suitable treatment by contacting companies in the sector with proven experience.
Obtaining from your health authority the confirmation of quality for human consumption following inspections and analytical checks.
Performing the regular maintenance of the plants (replacement of filter, sanitisation, etc.) as defined by the plant manufacturer and establishing a self-control plan to ensure water safety.
