				vertical sides and have a horizontal dimension of 4 to 12 inches. The bottom
				and sides of the hole must be carefully scratched with a sharp-pointed
				instrument to expose the natural soil interface. All loose material must be
				removed from the bottom of the hole which must then be covered with 2 inches of
				coarse sand or gravel when necessary to prevent scouring. Any soil which has
				sloughed into the hole before or during the percolation test must be
				removed.
3. The health authority
				may require an engineer to verify data relating to the depth of the high
				groundwater and bedrock, or areas subject or susceptible to flooding, the
				ground slope, and the results of percolation tests. Verification of maximum
				high groundwater includes, without limitation, a morphological study of soil
				conditions with particular reference to soil color and sequence of
				horizons.
4. If the natural soil
				condition has been altered by filling or other attempts to improve wet areas,
				the health authority may require the verification by the engineer to include
				observation of high groundwater levels under saturated soil
				conditions.
5. If the natural soil
				condition has been altered by filling or other attempts to improve the
				percolation rate of the soil, the health authority may require the verification
				by the engineer to include a determination of whether the fill material is
				suitable for an individual sewage disposal system.

Current through June 11, 2024
In conducting a percolation test, the following flow chart
				  must be used to determine which test procedure to follow:
1)
Fill the percolation hole with water to a
							 depth of at least 12 inches over the aggregate. Determine the time needed for
							 the water to seep away completely.
2)
Fill the percolation hole with water again
							 to a depth of at least 12 inches over the aggregate. Determine if the water
							 seeps away in 10 minutes or less.
3a)
If water is left in the percolation hole
							 after 10 minutes, proceed with the PRESOAKING PROCEDURE, followed by the SLOW
							 PERCOLATION TEST PROCEDURE.
3b)
If the water has completely seeped away
							 after 10 minutes, proceed with the FAST PERCOLATION TEST PROCEDURE.

Current through June 11, 2024
The following flow chart illustrates the fast percolation
				  test procedure:
1)
Fill the percolation hole with water to a
							 level that is no more than 6 inches over the aggregate.
2)
From a fixed reference point, determine,
							 at 10-minute intervals, how much the water drops over the next 60 minutes. If 6
							 inches of water seeps away in less than 10 minutes, a shorter interval between
							 measurements must be used.
3)
Refill the hole as necessary to prevent
							 all water from seeping away. The level of the water must never exceed 6 inches
							 in depth over the aggregate.
4)
The amount of the drop in the level of the
							 water recorded for the final 10-minute period must be used to determine the
							 percolation rate.
NOTE:
The minimum time
				  in which a fast percolation test may be completed is 1 hour. The level of the
				  water must never exceed 6 inches over the aggregate during a fast percolation
				  test.

Current through June 11, 2024
The following flow chart illustrates the presoaking procedure
				  for a slow percolation test:
1)
Fill the percolation hole with clear water
							 to a minimum depth of 12 inches over the aggregate.
2)
Maintain at least 12 inches of water over
							 the aggregate in the hole for 4 hours.
3)
Any water remaining in the hole at the end
							 of the 4-hour period must be allowed to seep away. Do not remove the
							 water.
4)
Let the hole sit for not less than 16
							 hours or more than 30 hours. Swelling of the soil will occur during this
							 period. The SLOW PERCOLATION TEST PROCEDURE must begin no sooner than 16 hours
							 and no later than 30 hours after the end of the 4-hour soaking period.

The following flow chart illustrates the slow percolation
				  test procedure:
1)
Fill the percolation hole with water to a
							 maximum depth of 6 inches over the aggregate.
2)
From a fixed reference point, measure the
							 drop in the level of the water at 30-minute intervals, for a total of 4 hours.
							 If the first 6 inches of water seeps away in less than 30 minutes, the interval
							 between measurements must be reduced to 10 minutes and the length of the test
							 must be reduced to 1 hour.
3)
Fill the hole to a maximum depth of 6
							 inches over the aggregate as often as necessary to prevent the hole from
							 becoming empty.
4)
The amount of the drop in the level of the
							 water during the last interval must be used to determine the percolation rate,
							 except that if two successive measurements do not vary more than 1/16 inch, the
							 test may be stopped and the percolation rate may be determined.

1. All forms used in placing concrete must be
				smooth, and sufficiently designed and braced to maintain their alignment under
				the pressure of the concrete during placing.
2. Precast sections must be set evenly in a
				full bed of sealant. Excessively mortared joints must be trimmed flush.
				Sealants used between the joints are at the manufacturer's discretion, unless
				otherwise specified by the health authority. If grout is used, it must consist
				of two parts sand to one part cement with sufficient water added to make the
				grout flow under its own weight. The grout must be poured into a water-soaked
				groove, and filled to the top of the groove in the previously set section. If
				mastic joint compound is used, it must be placed along the walls of the groove
				unless a double amount of mastic joint compound is to be used as a further
				precaution against leakage. If a double amount of mastic joint compound is
				used, the mastic sealant must be placed on the two shoulders of the groove. If
				polyurethane is used, it must be mixed as directed by the manufacturer of the
				polyurethane and placed in the groove. The next section must be placed while
				the foaming reaction for the previous section is still in process.
3. For the purpose of early reuse of forms,
				the concrete may be steam cured. Other curing by means of water spraying or a
				membrane curing compound may be used.
