Note: To calculate the volume of a square or rectangular lagoon of a size not listed above, the following formula may be used based on an inside berm slope of 3 horizontal to 1 vertical.
V = Volume in litres	H = Depth of liquid (maximum of 1.5 metres)	A = Area of bottom of lagoon in square metres	B = Area at mid-depth in square metres	C = Area at the high water level in square metres (maximum 1.5 metre depth)

A.6. Percolation Test Procedure

A.6.

• (1) A percolation test shall be carried out such that
  • (a) a minimum of two (2) percolation tests shall be conducted at test locations within the proposed effluent disposal area that are
    • (i) widely spaced, and
    • (ii) representative of typical soil conditions,
  • (b) a round hole shall be excavated and prepared to a depth of 900 mm (36 in.), and
    • (i) the surface of the wall of the hole shall be carefully picked off so no glazing or packing on the wall surface can affect the percolation of the water through the soil to water interface,

  • (c) the finished diameter of the test hole shall be 200 mm (8 in.),
  • (d) an initial soaking period of not less than 15 hours and not more than 30 hours is provided in which a minimum depth of 450 mm (18 in.) of water is admitted to the hole slowly and carefully, so as not to disturb the soil,
  • (e) after the initial soaking period of not less than 15 hours and not more than 30 hours, a minimum depth of 450 mm (18 in.) of water is maintained in the test hole for a minimum of 4 hours before starting measurement of the percolation rate,
  • (f) the water level in the hole is adjusted to 450 mm (18 in.),
  • (g) immediately after adjustment, the water is measured from a fixed reference point at 30 minute intervals,
  • (h) after each measurement, the water level is readjusted to 450 mm (18 in.),
  • (i) except as provided in Sentence A.6.(2), the test is continued until two successive water level drops do not vary by more than 3.2 mm (1/8 in.), and
    • i. a minimum of three measurements are made,
    • (ii) the last water level drop is used for measurement and the rate of drop of the water in the test hole is determined and recorded in minutes per 25 mm (per 1 in.) of water level drop,
    • (iii) the percolation rate is considered as provided in Sentence A.6.(3).
• (2) In soils in which the first 150 mm (6 in.) of water added after the 4 hour soaking period seeps away in less than 30 minutes
  • (a) the water level measurements shall be made at 10 minute intervals for a period of one hour,
  • (b) the last water level drop shall be used to calculate the percolation rate, and
  • (c) the percolation rate shall be considered as provided in Sentence A.6.(3).
• (3) The percolation rate shall be considered to be a rate not faster than the slowest percolation rate of the percolation test holes.

Note: The percolation tests form only part of an acceptable site evaluation. Additional evaluation of the soil type, Sodium Adsorption Ratio (S.A.R.), depth to impervious layer or water table, terrain, and other factors, must also be conducted.
