22.0.4. The person in charge of a municipal distribution system serving more than 500 persons and at least one residence with water that originates in whole or in part from surface water must keep a record containing observations about events likely to cause a water shortage, an obstruction or breakage of the withdrawal site or a failure in the screening system, the coagulation system, the sedimentation system, the filtration system, the disinfection system or the treatment system as a whole.

The observations referred to in the first paragraph include the following events:

(1)  natural or man-made events;

(2)  the proliferation of algae, cyanobacteria and aquatic plants;

(3)  suspected or measured increases in ammonia nitrogen.

The observations recorded must make it possible to locate the problem, to situate it in time and to assess its effect on the operation of the withdrawal site or treatment facility.

If the water of more than one surface water withdrawal site gets mixed in the treatment facility, a separate record must be kept for each withdrawal site.

The person in charge must sign the record when entering observations, preserve it for a minimum period of 15 years from the date of the last entry and keep it available to the Minister.
