Thetest holes ,··��· must be in the area where the absorption field is to be constructed and shall be placed fifty feet (50') apart in a rectangular pattern with the six foot (6') test bore to be· located in the center of the rectangular patterned test ...... _j hole location . 16 .8.2 Dio or bore the holes wi th horizontal dimensions of from 4 to 12 inches and �ertical sides to the depth of the bottom of the proposed di stri but ion trench , or at 1 east 36 inches deep . Ho 1 es can be bored wi th a 4- inch diameter post-hole type auger. 16 .8.3 Roughen or scratch the bottom and sides of the holes to provide a· natural surface. Remove al l loose material from the hole. Place two (2) inches of coarse sand or fine gravel in the ho le to prevent bottom scouring. 16.8.4 Fill the ho le with clear water to a maximum depth of twelve inches (12"} over the gravel . By refi lling if necessary, or by supplying a surplus reservoir of water (automatic siphon) keep water in the hole for at least four hours , and preferab ly overnight . 16 .8.5 In sandy soi ls containing little or no clay, the above saturation procedure is not necessary and the test can be made after the water from one fi lling has seeped away. 16 .8.6 Percolation rate measurements should be made on the day followi ng the saturation process, except in sandy soi ls. 16 .8.7 If water remains in the test hole after overnight saturation , adjust the depth to 12 inches over the gravel. From a fixed reference ;oint, measure the drop in water level over a 30-minute period . 16.8.8 if no water remains in the ho le after overnight saturation , add clear water to a depth of about 12 inches over the gravel . From a fixed reference point, me·asure the height of the water surface at approximately 30 minu-::e intervals over a 4-hour period, refi lling the hole to a depth of 12 inches as ·necessary. The drop wh ich occurs during the final 30 minute period is used to calculate the percolation rate. 16 .8.9 In sandy soi ls, or other soils in wh ich the first 12 -inches of wat er seeps away in less than 30 minutes, after the overnight satur���on period, the time interval between measurements can be taken as 10 minutes and the test run over a period of one hour . The drop wh ich occurs in the final 10-minute period is used to calculate the percolation rate. 16.8.10 Percolation test shal l be made by a civil engineer regi stered wi :h the State of Mi ssouri 8oard of Registration. 16.8.11 Perco1ation test site plan. The registered enaineer shall submit a site plan with the percolation test results wh ich must indicate : a. Te st hole locations and elevations . -· b. Bench marx location and elevations .
