(a) it shall meet the requirements of Appendix B, which is attached to and forms part of these regulations, or

(b) where the requirements of paragraph (a) cannot be met, consideration shall be given to alternate designs which will dispose of the liquid in the minimum size septic tank for a 3 bedroom, single family house, and which designs are in accordance with the requirement for alternate methods of disposal contained in the Regulations Governing Sewage Disposal and for which acceptable alternate designs and adequate area of appropriate soil is available for disposal, and the parcel shall be sized accordingly, except that where, in extraordinary and infrequent instances, the owner of the parcel does not wish to make the installation necessary for an acceptable alternate design in accordance with the foregoing, the subdivision may be approved, provided that the owner agrees in writing to registering a condition or covenant pursuant to section 219 of the Land Title Act in favour of the Crown at the time the subdivision is registered; such condition or covenant shall be satisfactory to the approving officer and shall restrict or prohibit the construction of buildings or structures on and (or) the use of any parcel until the necessary installations have been made, and

copies of the results of all tests shall contain the signature, occupation and permanent address of the person undertaking the tests and shall accompany the plans of the proposed subdivision when it is submitted to the authority having jurisdiction to receive subdivision applications.

Design of larger disposal system

6.05   Except where the Waste Management Act is applicable, where a parcel is less than 5 acres and is not served by a community sewer system and where the intended use has a greater design sewage flow per day than the minimum capacity septic tank for a 3 bedroom, single family house in accordance with the Regulations Governing Sewage Disposal, the design sewage flow of the intended use shall be used in accordance with the Regulations Governing Sewage Disposal to determine the area of soil required in section 6.04 (a) and all other requirements of section 6.04 shall be met.

Test results

6.06   Where any parcel in a proposed subdivision is less than 5 acres and is not served by a community sewer system, a copy of the plans and test results and measurements required in Appendix B as applicable to that parcel shall be submitted by the approving officer to the medical health officer or to the Regional Waste Manager, Ministry of Environment, as the case may be, for written reasons why he would or would not recommend approval of a subdivision based on the waste disposal capabilities of the soil on that parcel to meet with the requirements of these regulations or of the Waste Management Act, as the case may be.

Old subdivisions

6.07   Notwithstanding the requirements of sections 6.01, 6.02 and 6.03, existing parcels which are smaller than permitted in these regulations may be consolidated and resubdivided into new parcels, provided that

(a) all parts of all new parcels are contiguous;

(b) as many new parcels as the approving officer considers practicable shall meet the area requirements of these regulations;

(c) the degree of compliance with the area requirements of these regulations is not lessened on any new parcel;

Minimum frontage

6.08   (1) The minimum frontage of a parcel shall be 10% of the perimeter of that parcel, except where the minister, upon application by the owner, exempts him from this requirement.

(2) Application by an owner for exemption shall be in writing and shall state the ground on which the exemption is sought and shall be accompanied by 2 copies of a plan showing the proposed subdivision.

[am. B.C. Reg. 4/2010, s. 2.]

Panhandle lots

6.09   Without limiting the generalities of section 4.01 and notwithstanding the requirements of section 6.08, where a parcel is a panhandle lot capable of further subdivision, the approving officer shall be satisfied that the panhandle is adequate to provide a future highway.

Panhandle not part of minimum parcel area

6.10   Notwithstanding the requirements of sections 6.01 to 6.05, inclusive, where a parcel is a panhandle lot, the access strip or panhandle shall not be calculated as part of the minimum parcel area.

Where minimum does not apply

6.11   The requirements of sections 6.01, 6.02, 6.03 and 6.04 shall not apply

Less than 5 0
5 and more, but less than 10 500
10 and more, but less than 15 1 000
15 and more, but less than 20 1 500
20 and more, but less than 25 2 000
25 and more, but less than 30 2 500
When the percolation rate is 30 minutes or more, see section 6.04 (b) of the Subdivision Regulations.
Percolation tests shall be carried out in accordance with section 6 below.

2   Depending on the slope measured from the uppermost point on the parcel to the lowest point on the parcel, the results obtained in section 1 above shall be increased in accordance with the following:

Steepest slope (per cent)Minimum Area to be
Added to Parcel
(Sq. Ft.)
Less than 100
For each 5% or part thereof for 10% and over500

3   Regardless of the smallest parcel size permitted in accordance with sections 1 and 2 above, the parcel shall contain an area of soil suitable for sewage disposal not smaller than the following, as determined by the percolation rate:

Percolation rate (min./inch) Minimum Size of
Area of soil (Sq. Ft.)
Less than 5 1 000
5 and more, but less than 10 1 500
10 and more, but less than 15 2 000
15 and more, but less than 20 2 500
20 and more, but less than 25 3 000
25 and more, but less than 30 3 500

4   There shall be a minimum of 4 feet of natural porous topsoil above the groundwater table in the area of soil referred to in section 3 above, and a representative number of testholes shall be dug in that area to a minimum depth of 4 feet to demonstrate this.

5   The area of soil required for sewage disposal in section 3 above shall be capable of meeting the siting requirements for absorption fields in the Regulations Governing Sewage Disposal.

6   Percolation tests shall be undertaken, as follows:

(a) Percolation test holes shall be made at points and elevations selected as typical in the area of the proposed disposal field.

(b) One of these test holes shall be dug at each end of the area of the disposal field. Further holes may be required, depending on the nature of the ground and the results of the first test and the size of the proposed field.

(c) Test holes are usually drilled using an auger and to the depth of the proposed absorption trench. The standard depth is 24 inches, but the Public Health Inspector may approve or require holes varying from 18 to 32 inches in depth.

(d) The soil should be examined as it is removed from the test hole for some indication of its composition and likely percolation rate.

(e) To make the percolation test more accurate, any smeared soil should be removed from the walls of the test hole.

(f) If the soil contains considerable amounts of silt and (or) clay, the test hole should be presoaked before proceeding with the test. To do this, keep the hole as fully filled with water as possible for 4 hours. Proceed with the test immediately after presoaking.

(g) To undertake the test, fill the test hole with water. When the water level is 5 inches or less from the bottom of the hole, refill the hole to a depth of 24 inches or to the top. No recording of time need be done for these 2 fillings.

(h) When the water level after the second filling (step (g)) is 5 inches or less from the bottom of the hole, add enough water to bring the depth of water to 6 inches or more.

(i) Observe the water level until it drops to the 6 inch depth. At precisely 6 inches, commence timing. When the water level reaches precisely 5 inches depth, stop timing.

(j) The time in minutes for the water level to drop 1 inch is the percolation rate for that hole and is recorded in minutes per inch. The percolation rate of the absorption field is the average rate of all the percolation tests made for that field.

(k) Backfill the holes with the excavated soil and repeat the test in other locations. Record the results and submit to the local authorities.

(l) See section 4.07 of the Subdivision Regulations.

NOTE ON SECTION 6 — A percolation test is used to measure the permeability of the soil at the depth of the proposed drainage field. The percolation test will determine the rate, which is a measure of the time in minutes for the water level in a hole to drop 1 inch (from 6 inches from the bottom to 5 inches from the bottom of the hole) and is recorded in minutes per inch.
