Water Treatment Regulations

Reference Standards

Relevant regulations, in the context of water treatment and purification plants, for the agribusiness and industrial sectors, are as follows:

  • Wastewater. Legislative Decree 152/2006 (Annex 5), in particular:
    • Tab. 1, Emission limits for municipal wastewater plants;
    • Tab. 2, Emission limits for municipal wastewater plants discharging into sensitive areas;
    • Tab. 3, Emission limits to surface water and sewage, for industrial wastewater;
    • Tab. 3/A, emission limits for specific production cycles;
    • Tab. 4, Emission limits for urban and industrial wastewater discharging to land.
  • Wastewater reuse Dm 185/2003;
  • Water for human (and animal) consumption Legislative Decree 31/2001
    Implementation of Directive 98/83/EC on the quality of water intended for human consumption.
  • Water treatment systems air conditioning hot water production sanitary and solar thermal UNI 8065:1989 to UNI 8065:2019.

*Water for animal consumption

Regarding the quality of water for animal consumption, there is no specific reference legislation.

This represents a serious limitation related to the “quality” of life and “animal welfare,” which it should be remembered is enshrined in law. It is one of the priorities of the European Community, the achievement of “Human Food Security” through animal welfare.

EC Regulation. 178/2002 establishes the general principles and requirements of food law, for food safety and establishes procedures in the field of food safety. Water is defined as a food and as such must therefore comply with the directive a 98/83/EC (Decree 31/2001) of water for human consumption.

Scientific studies released by the world’s leading research centers have shown that “drinking” water if not of good quality can lead to:

Reduced production performance;

Reduced growth;


Uncoordinated movements, tremors, etc;

Altered quality of products and derivatives (meat/milk);

Nonnegligible damage to equipment and facilities;
