Question: No outlet filters are shown for the septic tanks. What system sizing flow rate is for bath house #1 and bath house #2, so we can properly size the outlet filters? Response: Attention is called to FDOH Rule 64E-6.008(2), F.A.C., which says in part, Outlet filters shall be installed within or following the last septic tank or septic tank compartment before distribution to the drainfield.

6 Additional Information: 34. The following information is provided to clarify installation requirements for tanks shown on the construction drawings: a. On sheets C 201 and C 204, the TOP EL. data given in the TANK SCHEDULE tables are for the design top of hatch elevations, which should match finish grade above each tank. b. Risers must be provided for all new tanks as needed to connect top of tank to hatches set at finish grade, including new tanks that may be needed for Bid Alternates 2 or 3, as applicable. c. As stated by the Park Manager during the pre-bid meeting, all of the septic tank locations at the campground are expected to be subject to occasional vehicular traffic associated with maintenance. The lids for tanks T-1 and T-2 should therefore be 8 thick, not 5 as previously shown on the plan details. d. With 8-inch lids, key design elevations for the affected tanks are modified as follows: T-1 top of hatch el. (flush w/grade) = ft. T-1 top-of-lid el. = ft. T-1 rim el. = ft. T-1 inlet invert el. = ft. T-1 outlet invert el. = ft. T-2 top of hatch el. (flush w/grade) = ft. T-2 top-of-lid el. = ft. T-2 rim el. = ft. T-2 inlet invert el. = ft. T-2 outlet invert (LPFM*) as needed to pass through riser at desired elevation. e. Pump tank T-6 is not expected to be subject to vehicular traffic. Key design elevations will be as follows: T-6 top of hatch el. (flush w/grade) = ft. T-6 top-of-lid el. = ft. T-6 rim el. = ft. T-6 inlet invert el. = ft. T-6 outlet invert (LPFM) as needed to pass through riser at desired elevation. * LPFM = low pressure force main In all other respects, the contract documents of which this is an Addendum, and attachments relative thereto, shall remain in full force and effect.
