7. (1) The following are prescribed as standards for the operation of a Class 1 sewage system: 1. Subject to paragraph 2, the sewage system shall receive or be used only for the disposal of human body waste. 2. If the sewage system has been specifically designed for the biological decomposition of non-waterborne biodegradable kitchen wastes or requires the addition of small quantities of plant matter to improve the decomposition of human body waste, it may receive such wastes in addition to human body waste. (2) A standard prescribed for a privy is that it be enclosed with a superstructure that, (a) shall be constructed of strong durable weatherproof materials; (b) has a solid floor supported by a sill constructed of treated timber, masonry or other material of at least equal strength and durability; (c) unless it is equipped solely as a urinal, is equipped with one or more seats each having a cover and being supported by an enclosed bench or riser which is lined with an impervious material on all interior vertical surfaces; (d) is equipped with a self-closing door; (e) has one or more openings for purposes of ventilation, all of which are screened; (f) has a ventilation duct that is screened at the top end and that extends from the under side of the bench or riser to a point above the roof of the superstructure; and (g) shall not have any openings for the reception of human body waste, other than urinals and those constructed in accordance with clause (c). (3) The following are prescribed as standards for the construction of an earth pit privy: 1. The bottom of the pit shall be at least 0.5 metres above the high ground water table. 2. The sides of the pit shall be reinforced so as to prevent the collapse thereof. 3. The pit shall be surrounded on all sides and on its bottom by not less than 0.6 metres of earth. 4. The surface of the ground in the area surrounding the pit shall be so graded that surface drainage in the area of the pit will be diverted away from the pit. 5. The earth around the base of the sides of the superstructure of the earth pit privy shall be raised or mounded to a height of at least 0.15 metres above ground level. (4) The following are prescribed as standards for the construction of a privy-vault or a pail privy: 1. The container or structure which is to be used for the holding or storage of sewage shall be watertight and made of a material which can be easily cleaned. 2. The earth around the base of the sides of the superstructure shall be raised or mounded to a height of at least 0.15 metres above ground level. 3. The surface of the ground in the area of the privy-vault or pail privy shall be so graded that surface drainage will be diverted away from the privy. (5) The following are prescribed as standards for the construction of a portable privy: 1. It shall have a watertight receptacle which shall be suitable for the holding and storage of any sewage deposited therein. 2. The receptacle for the holding and storage of sewage shall be designed and constructed in such a manner as to allow it to be easily cleaned and emptied. 3. It shall be constructed of such material and in such a manner that it can withstand the stresses to which it will be subjected during its transportation to and from sites where it is to be used and during loading and unloading from vehicles used for the transportation of the portable privy to and from sites where it is to be used.
