5 Applicant Name: WORKSHEET Installation of a Sewage System Consult Code and/or Backgrounder Document for more complete details. SECTION 3: SEWAGE SYSTEM INFORMATION Step 1: On page 2 of the Permit Application, System Information, circle which type of system (Class) you plan to install then determine the Flow Rate (Q). Step 2: Determine the Flow Rate (Q) Use steps below for Residential Occupancies only. For all other Occupancies see Tables A. & B. of the Building Code. The Total Daily Design Sewage Flow Rate (Q) is obtained by first establishing a base flow rate (BFR) based on bedrooms, up to five and then adding additional flow for: (a) bedrooms over five; or (b) living area over 200 square metres; or (c) fixture units of plumbing over 20 fixtures. Residential Occupancy Litres per day (L/d) DWELLINGS a) 1 bedroom dwelling 750 b) 2 bedroom dwelling 1100 c) 3 bedroom dwelling 1600 d) 4 bedroom dwelling 2000 e) 5 bedroom dwelling 2500 f) Additional flow for i) each bedroom over 5, or 500 ii) a) each 10 m 2 (or part of it) over 200 m 2 up to 400 m 2, 100 b) each 10 m 2 (or part of it) over 400 m 2 up to 600 m 2, and 75 c) each 10 m 2 (or part of it) over 600 m 2, or 50 iii) each fixture unit over 20 fixture units 50 Transfer all information from the Worksheets to the permit in the appropriate sections.

Minimum Tank Volume for Non-Residential Occupancies: 3 times Q = litres. Proposed Tank Volume: litres. Note: minimum allowable tank volume is 3,600 L TRENCH LENGTH PROPOSED The formula for calculating the length of pipe (L) is L=QxT D /200. L= metres. Proposed Length: L =. Note: Minimum length is 40 metres. Complete where patented product is proposed: Name and model of product:. (Attach BMEC authorization) Length of trench based on BMEC authorization = metres. FILTER BED EFFECTIVE SIZE, FILTER BED EXTENDED AREA, MANTLE AREA Effective area = Q/75 = m 2 where Q is 3000 litres or less. Effective area = Q/50 = m 2 where Q is over 3000 litres. Min. Extended Filter Sand Area (A) A = Q x T N / 850 = m 2 Mantle area = Q / LRM = m 2.

7 CLASS 5 SYSTEMS HOLDING TANK PROPOSED VOLUME Minimum volume of holding tank is 7 times Q. Proposed Tank Volume litres. Note: Minimum allowable tank volume is 9,000 litres. TERTIARY SYSTEM DESIGN Attach to permit application Step 3: Dwelling Information - required. Step 4: Soils Information: How to Determine Soils to be Used The Northwestern Health Unit requires documentation on the soils that are to be used by a certified soil technician to determine the T time for conventional type fields or suitability as filter bed sand for filter bed systems. A Laboratory report must be attached to Sewage Permit Application. Guide for Estimating Percolation Rate of Native Soil Loading Rates for Fill-Based Trenches and Filter Beds ESTIMATED ASSIGNED SOIL TYPE T Time Min/cm Percolation Time (T N ) of Native Soil, min/cm Loading Rates LRM (L/m 2 ) /day Coarse gravel, no fines < T Gravel, some small rocks < T 35 8 Gravel sand mix, some fines < T 50 6 Sand, uniform, some fines T > 50 4 Sand/loam mix Loading Rate of Mantle (LRM) from above table: Clay Mixtures LRM = L/d /m 2 / day Clay > 50 The Design Soil (T D ), Mantle Soil (T M ) and the Native Material (T N ) information is entered on the Soils Information of the sewage permit. Step 5: Test Pit Soil Information Required: Except as otherwise directed by the Northwestern Health Unit, a minimum of two (2) test pits must be used. The soil profile from the test pits and any percolation results must be included as part of the plans submitted for approval. The soil profile must be to a depth that is at least 1.0 metre below the bottom of the proposed field bed or trench. TEST PIT 1 TEST PIT 2 Depth in metres Description of soil. List colour and type.
