If needed, percolation tests must be conducted within the boundary of the proposed absorption system. The percolation test must be completed by a qualified site evaluator approved by the reviewing …

The test is continued until two successive water level drops do not vary by more than 1/8 inch. At least three measurements are made. After each measurement, the water level is readjusted to the 6 inch …

Percolation Test Procedure This Appendix is to be used to establish clear direction and methodology for percolation testing in Lassen County.

Begin the test for each test hole at five (5) minutes intervals. Fill or adjust the depth of the water level in each test hole to approximately 6” above the gravel. Record the time the water is poured into the test …

Determine the percolation rate twenty-four (24) hours after water is first added to the hole. This procedure is to insure that the soil is given ample opportunity to swell and to approach the condition …

The San Joaquin County Environmental Health Department (EHD) has adopted the following procedure in order to evaluate and process percolation results uniformly, effectively and quickly.

A home percolation test is a simple way to measure how quickly your soil drains and to determine how much area you need to infiltrate the greywater. Professional percolation tests, required for septic …

To determine the percolation rate for the site, add the individual percolation rates for the last test and divide by the number of test holes. Although only three test holes are required, the person …

If after filling the hole twice with 12” of water, all 12” of water seeps away in less than 10 minutes, no further presoaking is needed and you can proceed with the percolation test immediately.

A percolation test consists of digging one or more holes in the soil to be tested, filling the holes with water up to a specific level, and then timing the drop of the water level as the water percolates into …
