(b)  “privy” means a toilet with no water-flushing system, built outside an isolated dwelling;
(c)  “compost toilet” means a toilet operating without water and without effluent, in which fecal matter is transformed into compost;
(c.1)  “leaching field” means a work intended to distribute the effluent of a standard sand-filter bed, advanced secondary treatment system or tertiary treatment system to complete purification by seepage through the disposal site;

(d)  “settling tank” means a receptacle in which the effluent from an aeration tank is clarified;
(e)  “clarified water” means the effluent from a septic tank or an aerated waste treatment plant;
(f)  “grey water” means kitchen, bathroom, laundry water and water coming from any appliance other than a toilet;
(g)  “waste water” means toilet effluents combined with grey water;
(h)  “soil absorption system” means a work intended to spread over the effluent of a primary or secondary treatment system to complete purification by seepage through the disposal site;
(i)  “soil absorption field” means a soil absorption system composed of absorption trenches;
(j)  “seepage bed” means a soil absorption system built without trenches in a single excavation and constituted of a seepage bed;

(k)  (paragraph revoked);
(l)  “standard sand-filter bed” means a work built into impermeable or low permeability soil with borrowed sand;
(m)  “above-ground sand-filter bed” means a soil absorption system built above high permeability, permeable or low permeability soil with borrowed sand;
(n)  “holding tank” means a watertight tank intended for storing sewage from a chemical or low-flush toilet or grey water before haulage;
(o)  “septic tank” means a primary treatment system composed of a tank intended for receiving waste water or grey water;

(u)  “isolated dwelling” means a single or multi-family dwelling containing 6 bedrooms or fewer which is not connected to a sewer system authorized under section 32 of the Act; any other building discharging waste water only and whose total daily flow is no more than 3,240 litres is considered to be an isolated dwelling;
(u.1)  “impermeable soil” means soil whose percolation time is equal to or greater than 45 minutes per centimetre or whose coefficient of permeability is equal to or less than 6x10-5 cm/s or which, according to the relationship of soil type to permeability established in accordance with Schedule 1, is in the impermeable zone;
(u.2)  “low permeability soil” means soil whose percolation time is equal to or greater than 25 minutes and less than 45 minutes per centimetre or whose coefficient of permeability is greater than 6x10-5 cm/s and equal to or less than 2x10-4 cm/s or which, according to the relationship of soil type to permeability established in accordance with Schedule 1, is in the low permeability zone;
(u.3)  “permeable soil” means soil whose percolation time is equal to or greater than 4 minutes and less than 25 minutes per centimetre or whose coefficient of permeability is greater than 2x10-4 cm/s and equal to or less than 4x10-3 cm/s or which, according to the relationship of soil type to permeability established in accordance with Schedule 1, is in the permeable zone;
(u.4)  “high permeability soil” means soil whose percolation time is less than 4 minutes per centimetre or whose coefficient of permeability is greater than 4x10-3 cm/s or which, according to the relationship of soil type to permeability established in accordance with Schedule 1, is in the high permeability zone;
(v)  (paragraph revoked);
(w)  “available area” means an area of land without trees, shrubs or structures which is used for purposes other than the circulation or parking of motor vehicles;
(x)  “disposal site” means the part of natural land intended to receive a system for the discharge, collection or disposal of waste water, grey water or toilet effluents;
(y)  “low-flush toilet” means a toilet in which the quantity of evacuated water is less than 1.5 litres per flush;
(z)  “chemical toilet” means a toilet in which fecal matter is treated with chemicals, recirculated and periodically evacuated;
(z.1)  “CFU” means colony forming units.
