... %./ <br /> Caution must be given to the buoyancy potential of the tanks, due to the potentially high groundwater <br /> table. If free groundwater, or the capillary fringe is encountered during tank emplacement, Chesney <br /> Consulting must be contacted to assess the situation. A six-inch bedding layer of sand(does not <br /> have to be washed) must be placed on the floor of each of the four septic tank excavations. <br /> The second maintenance issue will be the washing off the BioTube filters periodically,preferably at <br /> tank pump-out. A water line with a hose bibb should be installed at each lift station location for <br /> filter maintenance. <br /> Two clean-outs must be installed on the six-inch ABS influent line from the new Office Building to <br /> the fust septic tank. One clean-out must be near the Office Building and the other clean-out near the <br /> fust septic tank, wherever convenient. <br /> Clean-outs must also be installed at the distal ends of each lateral through what is referred to as <br /> "tum-ups"as noted on the plan schematics. By using a long"bottle-brush"arrangement,the <br /> interiors of the laterals can be cleaned of scum and slime build-up. <br /> Water softeners should not be installed because the sodium from water softeners will bind the clay <br /> fraction of the soil and impede permeability. Although this phenomenon is debated in the scientific <br /> literature, it is our opinion that it is a distinct possibility and should be avoided since it could lead to <br /> a decrease in disposal area longevity. <br /> After the new well for the project is drilled, it must be tested under Item 3c. of the Conditions of <br /> Approval. If the well water is high in any of the tested constituents, filtration such as reverse <br /> osmosis filters must be installed. <br /> The building designer/engineer/architect, the plumber, the landscaper, and the wastewater disposal <br /> system installer must all coordinate so that proper grades are established and maintained. In <br /> addition, effluent lines should not cross fresh water or electrical lines. If crossing cannot be avoided, <br /> the wastewater lines should cross under fresh water lines. <br /> Sprinkler irrigation over both disposal areas must be carefully considered so as to not inundate the <br /> filter beds. During the spring and summer months, irrigation should be done intermittently during <br /> the day and/or evening hours. For example, the sprinklers could run for five minutes, six times per <br /> day. Irrigation during the wintertime should be suspended. Run time and number of daily irrigations <br /> should be determined by the landscape contractor. <br /> Another source of nitrate loading can be from the lawn or other landscape type plants that may be <br /> planted over the filter bed area. It is recommended not to use any nitrogen fertilizer in this area. If it <br /> is deemed necessary to use them, "slow release"nitrogen fertilizers should be used on the lawns <br /> and/or landscaping to reduce nitrate loading from the disposal area. <br /> Accurate"as-builts"of the septic system to be installed in the future must be supplied to the <br /> Environmental Health Department. All applicable"distance"and"setback"requirements must be <br /> strictly followed. <br /> 23 <br /> Chesney Consulting <br />
