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

Section 4.1 Disposition versions

2020-12-03

4.1. Content of the permit application: For the purposes of section 4, an application for a permit to install a system for the discharge, collection or disposal of domestic waste water, grey water or toilet effluents from a building or site referred to in section 2 must include

(1)  the name and contact information of the person referred to in section 4;

(2)  the cadastral designation of the lot on which the project is to be carried out or, if there is no cadastral designation, the most precise identification of the site where the project is to be carried out;

(3)  the number of bedrooms in the isolated dwelling or, in other cases, the total daily flow of discharged domestic waste water;

(4)  a characterization study of the site and natural land containing the following elements:

(a)  the topography of the site;

(b)  the grade of the disposal site;

(c)  the level of soil permeability at the disposal site, the methodology used to determine the soil permeability and the results obtained, unless a watertight system is being replaced by another watertight system or the project provides for another discharge to the environment because the conditions at the site do not allow for the siting of a soil absorption system or a leaching field;

(d)  the level of bedrock, underground water or any layer of permeable soil, low permeability soil or impermeable soil, as applicable, below the surface of the disposal site. For the replacement of a watertight system by another watertight system or a project providing for another discharge to the environment because the conditions at the site do not allow for the siting of a soil absorption system or a leaching field, only the level of bedrock and underground water is required; and

(e)  an indication of any element likely to influence the siting or construction of a disposal system;

(5)  a site plan to scale showing

(a)  the elements identified in the reference point column in sections 7.1 and 7.2 on the lot on which a system for the discharge, collection or disposal of domestic waste water, grey water or toilet effluents is proposed and on the contiguous lots;

(b)  the siting proposed for the system parts;

(c)  the installation depth of each system component; and

(d)  the installation depth of the soil absorption system, the standard sand-filter bed, the absorption field or the leaching field in relation to the level of bedrock, underground water or any layer of impermeable soil or low permeability soil below the surface of the disposal site;

(6)  a copy of the agreement referred to in the first paragraph of section 3.03 if the application pertains to a system serving a group of buildings that involve different owners; and

(7)  proof of the registration of the agreement referred to in subparagraph 6 in the land register.

In the case of a project providing for another discharge to the environment, the information and plan must describe the receiving area and,

(1)  in the case of discharge to a watercourse, specify the watercourse flow rate and the effluent dilution rate in the watercourse in low-water periods, the hydrographic network to which the watercourse belongs, as well as the location of the discharge site and the effluent sampling site. The flow rate and the effluent dilution rate are not required for a tertiary treatment system with disinfection or a tertiary treatment system with phosphorous removal and disinfection; and

(2)  in the case of discharge to a rainwater management system, show the water pathway up to the discharge site, and the location of the effluent sampling site.

This section applies to all permit applications, pursuant to section 4, for the construction of an additional bedroom in an isolated dwelling, a change in the use of a building or site or an increase in the operating or utilization capacity of a building or site referred to in section 2 where the construction, change or increase serves to increase the total daily flow of domestic waste water beyond the capacity of the system for the discharge, collection or disposal of domestic waste water, grey water or toilet effluents.

This section also applies to all permit applications, pursuant to section 4, for the reconstruction, renovation, modification or moving of any part of a system.

Subparagraph 4 of the first paragraph does not apply to installations covered by Divisions XII, XIII and XIV or to a watertight treatment system to which this Regulation applies that is connected to a municipal wastewater treatment works.

4.1. Content of the permit application: For the purposes of section 4, every application for a permit to install a waste water discharge, collection or disposal system for a building or site referred to in section 2 must include

(1)  the name and address of the person referred to in section 4;

(2)  the cadastral designation of the lot on which the project is to be carried out or, where there is no cadastral designation, the most precise identification of the location where the project is to be carried out;

(3)  the number of bedrooms in the isolated dwelling or, in other cases, the total daily flow of discharged water;

(4)  a characterization study of the site and natural land conducted by a person who is a member of the appropriate professional order, containing the following elements:

(a)  the topography of the site;

(b)  the disposal site grade;

(c)  the soil permeability at the disposal site, specifying the methodology used to determine soil permeability;

(d)  the level of bedrock, underground water or any layer of permeable soil, low permeability soil or impermeable soil, as the case may be, below the surface of the disposal site; and

(e)  mention of any element that may influence the siting or construction of a disposal system; and

(5)  a site plan to scale showing

(a)  the elements identified in the Reference point column of sections 7.1 and 7.2 on the lot on which a waste water discharge, collection or disposal system is proposed and on the contiguous lots;

(b)  the siting proposed for the parts of the waste water discharge, collection or disposal system;

(c)  the installation depth of each component of the disposal system; and

(d)  the installation depth of the soil absorption system, the standard sand-filter bed, the absorption field or the leaching field in relation to the level of bedrock, underground water or any layer of impermeable soil or low permeability soil below the surface of the disposal site;

(6)  a copy of the agreement provided for in the first paragraph of section 3.03 where the application pertains to a system serving a group of buildings that involve different owners;

(7)  proof of the registration of the agreement referred to in subparagraph 6 in the land register.

In the case of a project providing for other discharge into the environment, the information and plan must describe the receiving area and,

(1)  in the case of discharge into a watercourse, specify the water flow and the effluent dilution rate in the watercourse in low-water periods, the hydrographic network to which the watercourse belongs, the location of the discharge site and the effluent sampling site; or

(2)  in the case of discharge into a ditch, the plan must show the hydrographic network to which the ditch belongs and the location of the discharge site and the effluent sampling site.

If the system is to serve a building or site other than an isolated dwelling or a hunting or fishing camp, the information and documents referred to in this section must be signed by an engineer who is a member of the Ordre des ingénieurs du Québec. The information and documents must be filed with certification by the engineer that the system complies with this Regulation and is capable of disposing of the waste water having regard to the specific characteristics of the waste water.

Subparagraph 4 of the first paragraph does not apply to the installations to which Divisions XII, XIII and XIV apply, or to a watertight disposal system referred to in this Regulation connected to municipal waste water treatment works.
