Tests and controls

Metropolitana Milanese is in charge for the quality of the delivered drinking water and it operates in compliance with the provisions set forth by the Italian Legislative Decree No. 31/01 of 2003. In its test laboratory Metropolitana Milanese analyses some 180,000 parameters a year. It reports the quarterly test results to its clients on their bills and it also publishes them on the website. Ongoing control of the water quality, mainly flowing out of the stations and the implementation of internal procedures make it possible to do whatever is necessary to guarantee that the set parameter values are met by a wide margin.
