DHHS has a well log on file but the septic system is unpermitted. My client purchased this lot with the above mentioned on site services and he is proposing to improve the lot by building a three bedroom home. In the process he is attempting to conform to the DHHS on site services ordinances so that he may receive a land use permit for his proposed improvements. To verify the septic systems construction, the system was uncovered at two locations: at the septic tank and near the end of the leach field. The enclosed asbuilt illustrates the conditions I observed. The test pit near the end of the leach field was excavated to approximately 12 feet to verify separation to ground water and to perform a perc test at the depth of the existing system, approximately 6.0 feet. No ground water was encountered during excavation to a depth of 12 feet below. A monitoring tube installed and was checked on Oct. 2 and was dry. In summary, the septic system consists of a baffled 1000 gallon tank (recently pumped) and a deep trench leach field 90 feet in length underlain by 3.0 feet of sewer rock. A perc test was performed on the poorly graded gravel with silt, at approx. 5.5 feet resulting in a perc rate of 2.5 minutes per inch (or 1.2 gpd/sq, ft). With an application rate of 1.2 gpd/sq ft the proposed improvements will require approx. 375 square feet of absorption area. The existing system has 540 sq. feet of absorption area. I conducted a septic adequacy test and a 4 hour well flow test and the results are enclosed. In summary, the well produced 750 gallons within the 4 hour period. The leach field was dry prior to the test and absorbed 450 gallons with in 90 minutes with a total change in depth of 12 inches. Both leach field monitoring tubes were monitored to ensure equal trench distribution. If you have any questions, please do not hesitate to call. Thank you.
