..~Percolation Test:
l- Number and location of tests: Three or more tests shall be made in sep-
arate test holes spaced'uniformly over the proposed dra,infield site.
2- {Type of test hole: Dig or bore the holes with horizontal dimensions of
from 4 to 12 inches,,and vertical sides, to the depth of the proposed absorp-
tion trench. Holes may be bored with a 4-inch auger if desired,
3- Preparation of the test hole: Carefully scratch t'_ze bottom and sie of
the hole with a knife blade or sharp -pointed insL-r rier.t; in order to remove
any smeared soil surfaces and to provide a natural soil interface into which
water may percolate.. Remove all loose. material from the hole, Add 2 inches
of course washed sand or fine gravel to protect tie bottom f ^or. scouring and.
sediment.
-4- Saturation and swelling of the soil: Fill the hole with clear water to'
a minimum.depth of 12 inches over the gravel. Keep water in Elie hole, by
refilling if necessary,, for at least 4 hours and preferably .overnight. If
soil, other than loose sand had a dry appearance when hole was ni tia_1_ly
dug, soil must be allowed to -swell overnight after the soaking per_od to
permit it to approach the condition it w?11 be in when s;rstem is operating.
.:If soil was initially wet to saturation proceed as in Item 5 after the 4
.hours. of soaking.
Percolation rate measurement:
A. After saturating the soil and permitting it to swell;, adjust depth of
water in the test hole to 6 inches over the gravel. From a fixed'reference
point, measure the drop in water level over.a 30 minute priod; 'refilling
6 inches over the gravel if necessary. Th!:s drop in 30`mJ'nutes is used" to
calculate the percolation rate (time required in minutes for water to`fall
one inch).
SPECIAL NOTE: It may not be necessary to perform percolation tests on each
lot in the subdivision. See Subdivision Report,
Percolation Rate and Required Absorption Area. For Single Family Dwellings.
