The permit was for a 3 -bedroom system. In the design, the engineer (Tobben Spurkland, PE) listed the percolation rate for the test hole completed just prior to design as less than 6 min/in and noted that the application rate was 1.6 GPD/SF. However, he chose to design the system conservatively, applying an application rate of 1.0 GPD/SF for soils perking between 6-15 min/in. It appears that he did this because older test holes perked slower, although they were further from the trench. Please refer to the table below for a summary of the test holes on the lot. The resulting design was a shallow septic bed of dimensions 10' x 45' along with a 1600 -gallon Biocycle septic tank. Year Perk Rate Distance from trench 1985 33.3 min/in Approx 25' 1996 27 min/in > 30' 1999 <6 min/in (approx. 4.3 min/in) Adjacent It is understandable that the designer would want to use a somewhat weighted average of the two test holes that affect the trench for the design. Since the slower soils were much further away, an application rate of 1.4 could be considered reasonable. This allows for a bed size of 43' long for a 4 -bedroom system. Even so, the inspection report after installation actually lists the soil rating as 1.6 GPD/SF and the total absorption area as 450 SF, which allows for more than 600 gal/day (4 bedrooms). This may indicate that the soil composition was verified during installation. On April 24, 2023, we arrived on -property for a site visit to inspect this system. We found the monitoring tube to be completely dry. Given those calculations, along with the size of the Biocycle 1600 -gallon tank, we can say that this system was actually built with the capacity of for a 4 - bedroom home. We request that, based on those original permit numbers, this system be requalified as a 4 -bedroom system.

The submittal consist of three (3) drawings showing the present improvements on the lot and the adjoining properties, (sheet I/3), the proposed improvements of the lot, of which only the well and waste water system are subject to this permit application, (sheet 2/3), and a schematic of the waste water system, (sheet 3/3). Soil logs and percolation tests of applicable testholes are also enclosed. Leroy Reid did the original soil work in 1985. He found groundwater at 5 feet on July 19, which is probably a good indication of the high groundwater level. This company performed an additional percolation test on July 24, 1996. The percolation rate we observed agrees with the one reported by Mr. Reid. The groundwater levels were monitored during the fall of 1996. On October 18 the water was obsedved at 4 feet below ground level. A week later the water was at 4.75 feet below ground. The existing well on Lot 8 is artesian with overflow being discharge via a gardenhose in the proximity of the proposed beds. Surface water/shallow groundwater is present in the peat along the east portion of Lot 9. This water may be present because of the artesian well. The proposed well for Lot 9 must be adjacent to the existing well, so the proposed well may also be artesian, with the potential of causing overflow, either similar to the existing well, or ifa casing plug is installed, at the outside of the casing. Because of these concern, a BioCycle with the reduced absorption beds is preferable to a standard septic system. A standard septic system would require 1500 sq ft of absorption area, resulting in two beds extending across the total with of the lot. With a BioCycle two 10 foot wide beds each 37.5 feet long will be satisfactory for a three bedroom house. We propose to install a shallow bed system, consisting of two beds, each 10 feet x 37.5 feet. Due to the slope of the lot and the potential for high groundwater levels, we propose to excavate to the bottom of the peat/organic layer, replacing that material with Lake Otis gravel or sand. The two beds will be installed at different elevations, approximately a 4 feet difference, a crossover with a "bump" will be utilized to leave the bottom bed in reserve until the top bed fills up and overflow. This is a common and accepted practice. The proposed location of the well is adjacent to the existing well on Lot 8. The newly adopted well ordinance does not address the separation between wells, or location of wells with respect to lot lines. There is a small structure on Lot 10, a field inspection did not locate any wells or septic systems on this lot. The waste water system design is based on the following: Ground Water at 4 ft.

He found groundwater at 5 feet on July 19, which is probably a good indication of the high groundwater level. This company performed an additional percolation test on July 24, 1996. The percolation rate we observed agrees with the one reported by Mr. Reid. The existing well on Lot 8 is artesian with overflow being discharge via a garden_hose in the proximity of the proposed beds. Surface water/shallow groundwater is present in the peat along the east portion of Lot 9. This water may be present because of the artesian well. The proposed well for Lot 9 must be adjacent to the existing well, so the proposed well may also be artesian, with the potential of causing overflow, either similar to the existing well, or ifa casing plug is installed, at the outside of the casing. Because of these concern, a BioCycle with the reduced absorption beds is preferable to a standard septic system. A standard septic system would require 1500 sq ft of absorption area, resulting in two beds extending across the ~otal with of the lot. With a BioCycle two 10 foot wide beds each 37.5 feet long will be satisfactory for a three bedroom house. We propose to install a shallow bed system, consisting of two beds, each 10 feet x 37.5 feet. Due to the slope of the lot and the potential for high groundwater levels, we propose to excavate to the bottom of the peat/organic layer, replacing that material with Lake Otis gravel or sand. The two beds will be installed at different elevations, approximately a 4 feet difference, a crossover witl~a "bump" will be utilized to leave the bottom bed in reserve until the top bed fills up and overflow. This is a common and accepted practice. The proposed location of the well is adjacent to the existing well on Lot 8. The newly adopted well · ordinance does not address the separation between wells, or location of wells with respect to lot lines. There is a small structure on Lot 10, a field inspection did not locate any wells or septic systems on this lot. The waste water system design is based on the following: Ground Water at 5 ft. Use Standard Bed Soil Rating. 27 and 33 min/in = . 6 gal per sq.ft/day No. of Bedrooms 3 Required Area per Bedroom: 150/. 6 = 250 sq.ft.. Total area required: 3 x 250 = 750 sq ft Bed Width 10 ft Bed Length 75 ft Use two beds each 37.5 ft Total depth: 2 feet Remove organic material, replace with Lake Otis Gravel 6" sewer rock Silt Barrier 3 feet of cover BioCycle 6000 The installation of this septic system will not prevent wells from be installed on the adjacent lots. The proposed septic system will not change the general slope of the area. Ponding and/or concentration of surface runoff will not result from this installation.
