8.2.1.1. — Scope

(1) This Subsection applies to the design of sewage systems.

Text · e-Laws consolidated snapshot

8.2.1.2. — Site Evaluation

(1) A site evaluation shall be conducted on every site where a new or replacement sewage system is to be installed.

(2) The percolation time shall be determined by either percolation tests or by classifying the soil according to the Unified Soil Classification System as described in Supplementary Standard SB-5.

(3) Where the percolation time is determined by a percolation test, there shall be a minimum of 3 locations selected, suitably spaced to accurately evaluate the leaching bed area, with the highest percolation time of the tests being used

Editor's note

This map follows the as-filed text of O. Reg. 350/06 for Article 8.2.1.2. of Division B, in which Sentence (3) ('... with the highest percolation time of the tests being used') ends without a sentence-ending period. The e-Laws consolidation editorially adds a terminal period, with no amending regulation making the change. This map preserves the as-filed wording.

8.2.1.3. — Sewage System Design Flows

(1) For residential occupancies, the total daily design sanitary sewage flow shall be at least the value in Column 2 as determined from Table 8.2.1.3.A.

(2) For all other occupancies, the total daily design sanitary sewage flow shall be at least the value in Column 2 as determined from Table 8.2.1.3.B.

(3) Where a building contains more than one establishment, the total daily design sanitary sewage flow shall be the sum of the total daily design sanitary sewage flow for each establishment.

(4) Where an occupancy is not listed in Table 8.2.1.3.B., the highest of metered flow data from at least 3 similar establishments shall be acceptable for determining total daily design sanitary sewage flow.

Editor's note

In the notes to Table-8.2.1.3.A., Table-8.2.1.3.B., a separating space follows the footnote reference numbers; the e-Laws consolidation omits it. The footnote text is identical.

Notes to Table 8.2.1.3.B.:

(1)The occupant load shall be calculated using Subsection 3.1.17.

(2)Flea markets open more than 3 days per week shall be assessed using the volumes stated under the heading “Stores”.

(3)Where multiple calculations of sanitary sewage volume is permitted the calculation resulting in the highest flow shall be used in determining the design daily sanitary sewage flow.

(4)The number of fuel outlets is considered the maximum number of gas nozzles that could be in use at the same time.

8.2.1.4. — Clearances

(1) Unless it can be shown to be unnecessary, where the percolation time is 10 minutes or greater, the location of all components within a sewage system shall be in conformance with the clearances listed in Articles 8.2.1.5. or 8.2.1.6.v1

(2) Unless it can be shown to be unnecessary, where the percolation time is less than 10 minutes, the clearances listed in Articles 8.2.1.5. and 8.2.1.6.v1 for wells, lakes, ponds, reservoirs, rivers, springs or streams shall be increased to compensate for the lower percolation time.

(3) No building shall be constructed closer to any part of a sewage system than the clearances listed in Articles 8.2.1.5. or 8.2.1.6.v1

(4) If more than one sewage system is located on a lot or parcel of land, there shall be no overlap of any part of the systems.

Editor's note

This map follows the as-filed text of O. Reg. 350/06 for Article 8.2.1.4. of Division B, in which Sentences (1) and (3) refer to the clearances listed in 'Articles 8.2.1.5. or 8.2.1.6.' using the plural 'Articles', because the reference is to two articles. The e-Laws consolidation editorially renders both references in the singular as 'Article 8.2.1.5. or 8.2.1.6.', with no amending regulation making the change. This map preserves the as-filed wording.

8.2.1.5. — Clearance Distances for Class 1, 2 and 3 Sewage Systems

(1) Except as provided in Sentences 8.2.1.4.(1) and (2), no Class 1, 2, or 3 sewage system shall have a horizontal distance of less than that permitted by Table 8.2.1.5.

Editor's note

This map follows the as-filed text of O. Reg. 350/06 for Article 8.2.1.5. of Division B, in which Sentence (1) reads 'no Class 1, 2, or 3 sewage system' with a serial comma before 'or'. The e-Laws consolidation editorially drops the serial comma, rendering 'Class 1, 2 or 3', with no amending regulation making the change. This map preserves the as-filed wording.
