DocuSign Envelope ID:81E05E8E-EED7-43D3-8B8A-08110E72140A <br /> The alarm circuit shall be supplied ahead of the pump circuit overload device(on a separate <br /> circuit). The alarm shall be provided with a test button-which activates both the light and horn. In <br /> the event of a high-water condition, activation of a"silence" switch will bypass the horn and <br /> leave the visual alarm on. Any recurrence of the high-water condition will automatically <br /> reactivate the horn and light. Alarm panels that are mounted indoors may be used in addition to, <br /> but not instead of the exterior alarm panel. <br /> PUMP CONTROLS (FLOATS)Electrical control floats or similar devices designed for detecting <br /> effluent levels shall be provided to activate and deactivate the pump. The pump-off elevation <br /> shall be set to keep the pump submerged at all times. A separate float to activate the high-water <br /> alarm shall be set to activate within 6 inches of the pump-on elevation. Underwriter's Laboratory <br /> or an equivalent third party electrical shall list the level sensing devices testing and listing agency. <br /> The floats shall be supported utilizing durable, corrosion resistant material, and shall be <br /> adjustable,removable,and replaceable without requiring dewatering, entrance into the tank,or <br /> pump removal. An acceptable method would be to provide a PVC vertical weighted pipe with <br /> the float cables secured at the proper elevation using"all stainless steel"clamps at the float <br /> pivot points. Care must be taken to ensure that the sharp edge of the clamp does not bear on the <br /> wire insulation. Plastic tie-wraps alone, or strapping floats to the discharge pipe are not <br /> acceptable. <br /> CONDUCTORS (WIRES) shall be conveyed to the disconnect enclosure through waterproof, <br /> gasproof, and corrosion-resistant conduits. Wire grips, duct seal, or other suitable material shall <br /> be used to seal around wire and wire conduit openings. There shall be no splices within the pump <br /> tank or tank access riser. <br /> When necessary or specified,the tanks and control panel shall be protected from vehicular traffic <br /> by constructing guardrail or bollards. <br /> GENERAL DRAINFIELD REQUIREMENTS AND BEST CONSTRUCTION <br /> PRACTICES <br /> 1. Any clearing or preparation of the nitrification field shall be done without removal, <br /> disturbance, or compaction of soil. The contractor shall establish and stake the contour lines of <br /> the drainfield area before the installation and before the preconstruction conference,when <br /> required. Tree or sediment protective fencing shall be installed around septic area to <br /> eliminate construction traffic and soil compaction on septic area. <br /> 2. The drainfield lines shall be installed shallow, and on contour. Drainfield trenches shall be <br /> installed level and shall follow the ground contours. An engineer's level or laser shall be used in <br /> staking and constructing the lines. Trench depth shall not exceed the maximum specified on the <br /> Construction Authorization,unless otherwise specified, (i.e.ultra-shallow systems). Trench <br /> installation specifications from product manufacturers shall be followed. <br /> 3. No construction or backfilling shall be done when soil conditions are wet enough to cause a <br /> smearing or compaction of the soil in the drainfield or repair area. <br /> 4. The pipe between the septic tank and drainfield, or between the septic tank and pump tank <br /> shall be a minimum of 3" schedule 40 PVC or equivalent,with a minimum fall of 1/8"per foot. <br /> All joints from the septic tank to the drainfield shall be watertight. The pipe shall be on a firm, <br /> Project# 320059 <br />
