<br />d I5. Mechanical Components: <br />Mechanical components shall be installed in a properly vented location and all <br />® vents, air takes, and air hoses shall be protected from damage or blockage due <br />to snow, ice, water vapor accumulation, flooding, foaming or surcharging. <br />® 16. Distribution Box: <br /> A distribution box shall be used in absorption fields with three (3) Lateral lines <br />~ or more, and shall be of sufficient size to accommodate the necessary number <br />® of field lateral lines and shall be constructed with the inlet invert at least one <br /> (1) inch above the level of the outlet invert. The outlet inverts shall be three <br />~ (3) to six (6) inches above the floor of the distribution box. The box shall be <br /> constructed of Portland Type IIsulfate-resistant cement or other material <br />~. approved by the local health department. Prior to final inspection the <br />~ distribution box shall be leveled to verify evert distribution of tlx' efrluent. In <br />~ absorption fields that are twelve (12) feet wide and only two (2) distribution <br /> lines, a tee may be used in place of the distribution box. <br />~ 17. Sewage Pumping System Where Applicable: <br />r _ <br />p. a Non-clog pump opening shall have at least two (2) inch diameter <br /> solids handling capacity where raw sewage is pumped or at least '/z <br /> inch diameter solids handling capacity if previously settled effiuent is <br />~ pumped. <br /> b. Automatic liquid level controls shall be provided to start and shut off <br /> pumps at a frequency required by the design. <br /> c. Pressure pipe shall be of sufficient strength to accommodate pump <br /> discharge pressure and the pipe shall be sized to maintain a velocity of <br /> two (2) or more feet per second. <br />r d. Automatic air release valves shall be installed at high points in the <br /> pressure line where necessary to prevent air locking. <br /> <br /> <br />~ e. A storage basin preceding the pump shall be provided to allow pump <br /> cycling commensurate with the pump design capacity. The second <br />~ compartment of the septic tank shall not be used as a pumping <br />~ chamber unless it can be shown that the minimum 30-hour detention <br />® time w~71 not be decreased and the pump is screened or provided with <br /> an approved filtering device to assure that only liquid effiuent will be <br />~, discharged. <br /> <br />~^. f. The discharge line from the pumping chamber shall be protected from <br />V freezing by burying the pipe below frost level or sloping the pipe to <br /> allow it to be self draining. <br />~ <br />~ i 18.
