DEPARTMENT RECOMMENDS USING A FLOW SPLITTER DOWNSTREAM OF THE SEPTIC TANK TO ENSURE A EQUAL DISTRIBUTION/ DATE: DATE: TABLE 3-8 FALLING HEAD PERCOLATION TEST PROGEDURE 3o Number and Location of Tests Commonly a minimum of three percolation tests are performed within the area proposed for an absorption system. They are spaced uniformly throughout the area. If soil conditions are highly variable, more tests may be required. Preparation of Test Hole The diameter of each test hole is 6 in., dug or bored to the proposed depths at the absorption systems or to the most limiting soil horizon. To expose a natural soil surface, the sides of the hole are scratched with a sharp pointed instrument and the loose material is removed from the bottom of the test hole. Two inches of 1/2 to 3/4 in. gravel are placed in the hole to protect the bottom from scouring action when the water is added. Soakin~ Period The hole is carefully filled with at least 12 in. of clear water. This depth of water should be maintained for at least 4 hr and preferably overnight if clay soils are present. A funnel wi th an attached hose or stmtlar device may be used to prevent water from washing down the sides of the hole. Automatic siphons or float valves may be employed to automatically maintain the water level during the soaking period. It is extremely important that the soil be allowed to soak for a sufficiently long period of time to allow the soil to swell if accurate results are to be obtained. In sandy soils with l~ttle or no clay, soaking is not necessary. If, after filling the hole twice with 12 in. of water, the water seeps completely away in less than ten minutes, the test can proceed immediately. Measurement of the Percolation Rate Except for sandy soils, percolation rate measurements are made 15 hr but no more than 30 hr after the soaking period began. Any soil that sloughed into the hole during the soaking period is removed and the water level is adjusted to 6 in. above the gravel (or 8 in. above the bottom of the hole). At no time during the test is the water level allowed to rise more than 6 in. above the gravel. Immediately after adjustment, the water level is measured from a fixed reference point to the nearest 1/16 in. at 30 min intervals. Theltest is continued until two successive water level drops do not vary by more than 1716 in. At least three measurements are made, After each measurement, the water level is readjusted tO the 6 in, level. The last water level drop is used to calculate the percolation rate. In sandy soils or soils in which the first 6 in. of water added after the soaking period seeps away in less than 30 min, water level measurements are made at 10 min intervals for a i hr period, The last water level dropiis used to calculate the percolation rate. Calculation of the Percolation Rate The percolation rate is calculated for each test hole by dtvtdlnq the time interval used between measurements by the magnitude of the last water level drop. TEts calculation results in a percolation rate in terms of mtn/tn. To de~ermine the percolation rate for the area, the rates obtained from leach hole are averaged. (If tests in the area vary by more than 20 min/tn., variations in soil type are indicated. Under these circumstances, percolation rates should not be averaged.) Example: If the last measured drop in water level after 30 min is 5/8 in., the percolation rate = (30 mtn)/(5/8 in.) = 48 mtn/tn. 41 MUNICIPALITY OF ANCHORAGE DEPARTMENT OF HEALTH AND HUMAN SERVICES On-site Services 825 L Street, Room 502 343-4744 Required Cleanouts & Monitoring Tubes Cleanou~s Monitoring Tube _Cleanouts Septic Tank Mon ito~r ing Tube Tom Fink, Mayor Municipality o{ Anchorage Department of Health and Human Services 825 "L" Street P.O. 8ox 196650 Anchorage, Alaska 99519-6650 ENGINEER BULLETIN 91-6 September ].2, 1991 To: Ail Engineers Performing Percolation Tests for the Design of On-site Wastewater Disposal Systems Subject: Depth of Percolation Tests Density and permeability for a given soil type typically fluctuate with depth. Specifically, density usually increases and permeability usually decreases. To account for this variability and to ensure that percolation test results are indicative of the overall absorption capacity of the accepting soil stratum, we request that all tests be performed at the approximate mid-point depth of the accepting soil stratum.
