Construction and Operation Standards
12. (1) The following are prescribed as standards for installation of a Class 6 sewage system: 1. No person shall locate or cause or permit the location of the proprietary aerobic sewage treatment plant closer to an item set out in Column 1 of Table 3 than the horizontal distance set out opposite thereto in Column 2. 2. A leaching bed constructed as part of the sewage system shall be located in accordance with paragraph 1 of subsection 10 (2). 3. The sewage system shall comply with paragraph 8 of subsection 10 (1). 4. The sewage system shall include an audible failure warning alarm located to warn occupants of the building served of a malfunction in the operation of the proprietary aerobic sewage treatment plant. (2) The following are prescribed as standards for the construction of a leaching bed that is used in connection with a Class 6 sewage system: 1. The leaching bed, if constructed by means of absorption trenches, shall have, in any case, at least thirty metres of distribution pipe but, i. if serving a private dwelling, it shall have distribution pipe of a total length not less than two-thirds of the length set out in the appropriate column of Table 5 showing the design percolation time for the soil in the leaching bed opposite the number of bedrooms set out in Column 1 of Table 5, or ii. if serving a structure other than a private dwelling, it shall have distribution pipe of a total length not less than the value determined by the formula: L = QT/300 where L is the total length of distribution pipe expressed in metres, Q is the total daily sewage flow in litres and T is the design percolation time in minutes. 2. Where the leaching bed is constructed by means of absorption trenches, it shall conform to subsection 10 (2) and paragraphs 3, 4, 5 and 6 of subsection 10 (3). 3. The leaching bed may be constructed as a filter bed where, i. except as provided in subparagraphs ii to v, it conforms to subsection 10 (4), ii. the daily sewage load to the leaching bed does not exceed 10,000 litres, iii. if the leaching bed is serving a private dwelling with the number of bedrooms set out in Column 1 of Table 6, the area of the filter medium in the leaching bed is not less than that set out opposite the appropriate number of bedrooms in the column for Class 6 sewage systems, iv. if the daily sewage flow does not exceed 6,000 litres, the area is such that the loading on the surface of the filter medium does not exceed 150 litres per square metre per day, and v. if the daily sewage flow exceeds 6,000 litres, the area is such that the loading on the surface of the filter medium does not exceed 100 litres per square metre per day and the leaching bed is comprised of more than one filter bed. (3) The manufacturer or distributor of a proprietary aerobic sewage treatment plant shall have, for each type and model of plant sold, printed literature that describes the plant in detail and provides complete instructions regarding the operation, servicing, and maintenance requirements of the plant and its related components necessary to ensure its continued proper operation in accordance with its design and specifications. (4) The following are prescribed as standards for the construction, operation and maintenance of a Class 6 sewage system: 1. The proprietary aerobic sewage treatment plant and its related components shall be operated, serviced and maintained in accordance with the instructions referred to in subsection (3). 2. Servicing and maintenance shall be undertaken regularly and with a frequency necessary to ensure the proper operation of the plant and its components in accordance with its designs and specifications. (5) The person who constructs a Class 6 sewage system shall ensure that a copy of the literature described in subsection (3) is made available to the owner of the property on which the system is to be installed for retention by that person. (6) No person shall operate a Class 6 sewage system that is not a Class A sewage system unless the servicing and maintenance of the proprietary aerobic sewage treatment plant and its related components are carried out by a person who, (a) possesses the instructions referred to in subsection (3); and (b) if in the business of servicing and repairing sewage systems, is authorized by licence to service and maintain that type of proprietary aerobic sewage treatment plant or possesses other evidence, acceptable to the Director, demonstrating the person’s qualifications for such work. (7) No person shall operate a Class 6 sewage system that is a Class A sewage system unless there is a written agreement for the servicing and maintenance of the proprietary aerobic sewage treatment plant and its related components between the owner or operator and a person described in clause (6) (b) or an employee of the owner who, (a) is approved by the manufacturer for the servicing and maintenance of the proprietary aerobic sewage treatment plant and its related components; and (b) is approved for that purpose in writing by the Director and carries out the servicing and maintenance as part of his or her duties.
