V. INFLUENT COLLECTION AND MANAGEMENT The following information describes each wastewater source, collection and management prior to treatment and disposal by the Package Treatment Plant. Wastewater management for CGS can be considered a septic tank effluent pumping (STEP) system. All tank Cut Sheets and related information are found in Appendix I. • Each Hero Rental Lodge (25 Total)will connect to its own 1.5k gallon, monolithic/traffic- rated P&L Concrete, Inc. septic tank installed under a concrete slab. The slab will serve as a foundation for the Lodges and as septic tank anti-buoyancy. All influent piping will be alongside each slab for easy clean-out accessibility, as illustrated on the attached Design Plans and described in the Notes. The riser and lid for the front compartment of each tank will be outside of the slab footprint for easy accessibility by a pumper truck. Effluent from these septic tanks gravity flow to their respective Lift Stations. The riser and lid for the second compartment of each tank will come through the slab and will be under each Hero Lodge, but accessible through a two-ft crawl space. • Septic tank effluent from all 25 Hero Lodges will gravity flow into five separate, 1.5k gallon, monolithic/traffic-rated Jensen Infrastructure, Inc. Lift Stations. The Site Plans illustrate which Hero Lodges gravity into each specified Lift Station. Each Lift Station tank will have low-head duplex pump systems, with alarm/control panels. Lift Stations #1, #2, #3 and#4 will pump septic tank effluent (STEP)to the l0k gallon settling and flow equalization tank directly north of the filter bed,then effluent to gravity flow to PTP. • The Clubhouse will have a 1.0k gallon, monolithic/traffic-rated Jensen Infrastructure, Inc. grease interceptor tank and one 1.5k gallon, monolithic/traffic-rated Jensen Infrastructure, Inc. septic tank to serve the kitchen and Clubhouse Restrooms, respectively. Effluent from the 1.0k gallon grease interceptor tank will flow into the 1.5k gallon tank. Influent from the Caretaker's Apartment, which will be upstairs from the Clubhouse, will flow into the 1.5k gallon Jensen tank. Effluent from these two tanks will gravity flow to Lift Station#4. • The Restroom/Showers Building influent will flow to a septic tank on the east side of this building. • The Laundry/Housekeeping Building septic tank will be installed on the west side of the Building. Effluent from this tank will gravity under the ingress/egress road and flow into the liquid side of the Restroom Building septic tank. The combined effluent will then gravity flow to Lift Station#1. • The Garage Building will have a sink for hand washing with drain water gravity flowing to Lift Station#4. • The marina holding tank is discussed in Section VIII.
