Q-2, r. 22 - Regulation respecting waste water disposal systems for isolated dwellings
Section 2
Disposition versions
2. Scope of application: This Regulation applies to the disposal of domestic waste water, grey water and toilet effluents from the following buildings and site if they are not connected to a sewer system authorized by the Minister under the Act, or the watertight treatment system of the buildings or site is connected to a municipal wastewater treatment works:
(a) an isolated dwelling;
(b) a building other than the building referred to in subparagraph a that discharges domestic waste water, grey water or toilet effluents exclusively, and the total daily flow does not exceed 3,240 litres;
(b.1) a building that does not discharge domestic waste water, grey water or toilet effluents exclusively, whose plumbing system allows waste water to be segregated such that only domestic waste water, grey water or toilet effluents are carried to a domestic waste water discharge, collection or disposal system, and the total daily flow of the domestic waste water does not exceed 3,240 litres; and
(c) camping and caravanning grounds where domestic waste water, grey water or toilet effluents are discharged, and the total daily flow does not exceed 3,240 litres.
It does not, however, apply to the disposal of non-domestic waste water from a building referred to in subparagraph b.1 of the first paragraph. That water must be carried to a discharge, collection or disposal system compliant with the Act or the Agricultural Operations Regulation (chapter Q-2, r. 26).
It also applies to the development and use of a privy and a compost toilet, and to the management of the compost from the compost toilet if such a toilet serves a building or site referred to in the first paragraph or serves a building or site that is not supplied with water, to the extent that the building or site would discharge a total daily flow of domestic waste water that would not exceed 3,240 litres per day if it were supplied with water.
More specifically, it applies to a system for the discharge, collection or disposal of domestic waste water, grey water and toilet effluents from a building or site referred to in the first paragraph for the purpose of its installation, during its installation, as part of its operation, its abandonment and in the cases referred to in the second paragraph of section 4.
Despite the foregoing, the standards relating to the installation of a system serving a building or site referred to in the first paragraph already built or developed do not apply if the domestic waste water, grey water and toilet effluents do not constitute a nuisance, a source of contamination of well or spring water used for drinking water supply or a source of contamination of surface water, except in the cases referred to in the second paragraph of section 4.
2. Application: This Regulation applies to the disposal of waste water, grey water and toilet effluents from the following buildings and site if they are not connected to a sewer system authorized by the Minister under the Act or if the watertight treatment system of the buildings or site is connected to municipal waste water treatment works referred to in section 1 of the Regulation respecting municipal wastewater treatment works (chapter Q-2, r. 34.1):
(a) an isolated dwelling;
(b) a building other than the building referred to in subparagraph a that discharges only waste water, grey water or toilet effluents whose total daily flow is not more than 3,240 litres;
(c) camping and caravanning grounds where waste water, grey water or toilet effluents are discharged and whose total daily flow is not more than 3,240 litres.
It also applies to the development and use of a privy and a compost toilet, and to the management of the compost from the compost toilet where such a toilet serves a building or site referred to in the first paragraph or serves a building or site that is not supplied with water, to the extent that the building or site would discharge a total daily flow of waste water of not more than 3,240 litres per day if it were supplied with water.
More specifically, it applies to the systems for the discharge, collection or disposal of waste water, grey water and toilet effluents from the buildings or the site referred to in the first paragraph for the purposes of their installation, during their installation, as part of their operation, their abandonment and in the cases referred to in the second paragraph of section 4.
The standards relating to the installation of a system serving a building or site referred to in the first paragraph already built or developed do not apply where the waste water, grey water and toilet effluents do not constitute a nuisance, a source of contamination of well or spring water used for drinking water supply or a source of contamination of surface water, except in the cases referred to in the second paragraph of section 4.
2. Application: This Regulation applies to the treatment and disposal of waste water, grey water and toilet effluents from any new isolated dwelling as well as in the cases mentioned in the second paragraph of section 4.
It also applies to waste water, grey water and toilet effluents from an existing isolated dwelling except in cases where such effluents do not constitute a nuisance, a source of contamination of well or spring water used for drinking water supply or a source of contamination of surface water.
This Regulation applies, with the necessary modifications, to camping and caravan grounds where waste water is discharged. For the purposes of this Regulation, those grounds are considered to be buildings other than isolated dwellings.
Section 13 applies to septic tanks and section 59 applies to any holding tank.
However, this Regulation does not apply to an isolated dwelling being part of a seasonal camp referred to in subparagraph b of the first paragraph of section 18 of the Act respecting hunting and fishing rights in the James Bay and New Québec territories (chapter D-13.1). Such isolated dwelling must nevertheless be equipped with a privy placed at least 10 m from the isolated dwelling and from any watercourse or body of water, in a place which is not higher than the isolated dwelling. The privy must be in conformity with the standards prescribed in sections 47 to 49 or in sections 73 and 74.
This Regulation does not apply to an isolated dwelling that is part of a temporary industrial camp covered by the Regulation respecting the application of section 32 of the Environment Quality Act (chapter Q-2, r. 2).
