(1)  waste water, grey water and toilet effluents must be carried towards a primary treatment system, a secondary treatment system, an aerated installation, an advanced secondary treatment system or a tertiary treatment system that complies with Division V, V.2, XV.2 or XV.3, as the case may be;
(2)  the effluent of the primary treatment system must be carried towards a soil absorption system, a secondary treatment system, a standard sand-filter bed, an advanced secondary treatment system or a tertiary treatment system that complies with Divisions V.2 to X or with Divisions XV.2 and XV.3 or municipal waste water treatment works, as the case may be;
(3)  the effluent of a secondary treatment system or an aerated installation must be carried towards a soil absorption system, a standard sand-filter bed, an advanced secondary treatment system or a tertiary treatment system that complies with Divisions VI to X or with Divisions XV.2 and XV.3, as the case may be; where the secondary treatment system is watertight, it may also be carried towards municipal waste water works;
(4)  the effluent of a standard sand-filter bed or an advanced secondary treatment system must be carried towards a tertiary treatment system or a leaching field that complies with Division XV.3 or XV.4, as the case may be; in the case of the advanced secondary treatment system, it may also, where the system is watertight, be carried towards municipal waste water works;
(5)  the effluent of a tertiary treatment system must be carried towards a leaching field that complies with Division XV.4.
Notwithstanding subparagraphs 4 and 5 of the first paragraph, where the installation conditions provided for in Division XV.4 do not allow for the installation of a leaching field, the effluent of the systems referred to in those subparagraphs may be discharged into a lake, swamp, pond, watercourse or ditch in the cases provided for in Division XV.5.
