CONCLUSIONS AND RECOMMENDATIONS The wastewater flow volumes determined from the onsite well meter readings for the years 2018, 2019 and 2020 have determined an ADF among the three years to be 8,069 gpd. This flow volume also incorporates landscape irrigation, which is an indeterminable volume of this total. Consequently, the flows are certainly less than 10,000 gallons per day and therefore the facility is not required to be under the auspices of the Regional Water Quality Control Board in Sacramento. Calculations for the reserve/replacement areas on Parcel 27 reveal there is sufficient area for replacement structures, primarily seepage pits, and still maintain a minimum of 20% of the dispersal field in leachlines. From the soil percolation tests, the leachlines manage a small percentage of the effluent flows, with the seepage pits managing most of the effluent volume. Consequently, it is recommended to install three additional 48" x 25 ft deep seepage pits to connect to the existing seepage pits that are located at the ends of each leachline. Two seepage pits are permitted at the terminal end of leachlines per Section 9.9.7 of the SJC OWTS Standards. As referenced, the soil permeability under Parcel 27 is slow, and surprisingly slow for a sandy loam soil structure from 15 ft to 25 ft. It was decided to conduct a falling head permeability test in the 25 ft boring to determine water volume absorption. At the end of four hrs, it was measured that 126.1 gallons of water was absorbed, extrapolated from the 4.5" diameter boring. Given the importance of head pressure on soil permeability and observing that 73.5 gallons theoretically absorbed into the soil in the first 60 minutes, this volume could be extrapolated over 24 hrs if flow volumes from the CMMHP kept the seepage pits full: 73.5 gals per hr x 24 hrs/d = 1,764 gpd. 1,764 gallons/seepage pit x 3 seepage pits at the end of each leachline = 5,292 gpd. The ADF was determined to be 8,069 gpd. Therefore, the other referenced existing seepage pits must manage the flow volumes and justifies the installation of three additional seepage pits. The increase in dissolved oxygen content within the Nottingham treated effluent has proved to be extremely beneficial by lowering the highlighted constituents of concern in Table 5. Soil permeability also appeared to increase when measuring water levels in the seepage pits before oxygenation and observing no standing water In the pits after oxygenation. Ef Chesney Consulting
