10.2.5.6. A processing establishment or freshwater products cannery must have a drain network for the removal of rain water and waste water. Such network must be equipped with manholes, siphon trap pumps, protective grating and, where required by the operations, a solid matter interceptor.
Wash water pipes must be separate from the sanitary drain pipes for the washrooms, urinals and wash basins, so that such pipes do not interconnect inside the establishment or cannery.
If the drain network includes drain pipes, the inside diameter of such pipes must be at least 10 cm.
If the cooking tanks are connected to the drain network, the opening into such network must be equipped with a check-valve to prevent the reflux of waste water into the tanks.
The second and third paragraphs apply only in the case of a new establishment or cannery or, in respect of the second paragraph, in the case of an existing establishment or cannery that has been completely refloored or, in respect of the third paragraph, in the case of an existing room that has been completely refloored.
Where a new establishment or cannery is to be constructed, or where an existing establishment, cannery or room is to be completely refloored, the operator must so inform an inspector in writing not less than 30 days immediately prior to such construction or renewal.
