3. Prohibition: No person may discharge or allow the discharge into the environment of effluents from the toilet of an isolated dwelling or of waste water or grey water from an isolated dwelling.
The prohibition in the first paragraph is established within the meaning of the second paragraph of section 20 of the Act.
However, the first two paragraphs do not apply where such effluent is disposed of or discharged into the environment according to the provisions of Divisions III to XI, XV.2 to XV.5 or section 90.1, or where such effluent is purified in another disposal system authorized under section 32 of the Act.
In the case of an existing isolated dwelling or a fishing or hunting camp, waste water, grey water or toilet effluents may, in addition to the possibilities provided for in the third paragraph, be discharged into a system complying with any of Divisions XII, XIII and XIV.
An isolated dwelling rebuilt after a fire or another disaster is considered to be an existing dwelling if its reconstruction is allowed by municipal by-laws and the installation of the dwelling’s system for the discharge, collection or disposal of waste water, toilet effluents or grey water that was destroyed was not prohibited by an Act or a regulation in force at the time the system was installed. However, if a dwelling or another building covered by this paragraph must be connected to one of the installations that complies with Division XII, XIII or XIV, the dwelling may not contain more bedrooms than the dwelling that was destroyed and, in the case of another building, the total daily flow may not be increased.
No person may install waste water, grey water or toilet effluents discharge or disposal systems which are not in conformity with the standards prescribed in this Regulation, to serve an isolated dwelling, except in the case of a sewage system authorized under section 32 of the Act.
No person may build a new isolated dwelling or add a bedroom to an isolated dwelling if the isolated dwelling is not equipped with a system for the discharge, collection or disposal of waste water, toilet effluents or grey water in conformity with this Regulation.
