Monitoring Drain fields

The Turf-Tec Infiltration Rings can be used to install drain fields. The double ring is much more

accurate then just using a single ring or an excavated cavity to test for infiltration. However please

check with your local ordinances to see if an ASTM Infiltration test is required, if one is, you may

need to use the Turf-Tec 12 and 24 Inch Infiltration Rings.

Environmental testing

The Turf-Tec Infiltration Rings can be used to perform various types of environmental tests. It can

be used for testing fuel tank containment areas and spill clean up times. The Turf-Tec Infiltration

Rings can also be used for measuring urban runoff. It has also been successfully used for storm

water soil evaluations, forestry soil assessments and for groundwater recharge areas.

Monitoring test pits

When monitoring test pits, be sure you use the saturated method of testing and repeat the tests in

several areas. In addition, if testing in the bottom of test pits be sure the soil has not been

disturbed by the digging equipment. This is usually accomplished by excavating to within 2 to 4

inches of your desired testing depth by machine and then removing the last portion by hand

digging by with a flat shovel before taking your readings. This will insure you are taking readings

on undisturbed soils. If the soil is disturbed, you can re-tamp the area and confirm consistency in

compaction with a Penetrometer before testing infiltration.

Particular Specifications - Reason for the double ring

The Turf-Tec Infiltration Rings is equipped with a double ring. During use, both rings are filled up

with water but only the inner ring is measured. The reason for this is that you may notice that

during operation, one ring may infiltrate much faster than the other ring one because there will be

lateral movement of water around the cutter blade. This action will also create a seal for the

inner ring and give a much more accurate indication of the actual rate of infiltration.

Accuracy of testing the soil on the area in question

This tool is designed to test soil infiltration right on the area that is in question. It differs from lab

results because it is representative of all the conditions that naturally occur on that area. The Turf-

Tec Infiltration Rings accounts for the vegetative cover, soil organic matter content, soil physical

properties, compaction, soil texture and other factors. The variables all come into consideration

when using this tool to determine infiltration.

Checking infiltration at lower depths in the soil profile

If the Infiltration rate needs to be determined at lower levels in the soil profile, a post hole digger

can be used to remove the turf, thatch and mat. The Turf-Tec Infiltration Rings can then be

lowered into the hole and the rate of infiltration can be determined at that level. Maximum depth of

the Turf-Tec Infiltration Rings is approximately two feet. If readings are needed at lower levels a

backhoe can be used for excavation.
