Q-2, r. 22 - Regulation respecting waste water disposal systems for isolated dwellings

Full text
1.4. Total daily flow: The total daily flow of waste water from a building or site other than an isolated dwelling referred to in section 2 corresponds to the sum of the flows produced by each service offered. The flows for each service are calculated by multiplying the unit flow provided for in Schedule 1.1, which varies according to the type of services offered, by the corresponding number of units, which is set by considering the maximum operating or utilization capacity of the building or site concerned.
In the case of a service not included in Schedule 1.1, the total daily flow must be established on the basis of the unit flow of a comparable service.
For the purposes of sections 1.3, 2, 15, 18, 22, 28, 33, 38, 44, 87.23 and 87.25, the total daily flow of waste water from a building or site other than an isolated dwelling referred to in section 2 takes into account the toilet effluents that could be discharged by the building or site even if the building or site is equipped with a privy or a compost toilet.
