➢ Secondary Treatment— Effluent Filter - Septage from the ciear zone of the septic tank flows through an Orenco biotube effluent filter placed inside of the septic tank, attached to the outlet of the tank. Suspended particles larger than I/8" are filter out by the biotube effluent filter. ➢ Final Treatment—Screened septage is discharged out of the lift tank through the biotube pump vault to drain field consisting of In�ltrator BioDiffusers. As the septage trickles through the soil below biochemical processes remove harmful viruses and bacteria. 6) Description of Treatment System - ' ➢ Septic Tank— Use a I 500 gallon Xerxes fiberglass septic tank. Inlet and outlet of the � tanks must have cast in place rubber fittings to create a watertight seal around the inlet , and outlet pipes. ➢ Risers— Use 24" diameter heavy corrugated pvc pipe. A watertight seal must be � created between top of tank and the each riser. Top of risers shall be 2-3" above finished grade. ➢ Riser Covers — Use 24" diameter fiberglass covers with gasket, Orenco model # FL24G (or equivalent). Do not bury riser covers. ➢ Effluent Filter— Use an Orenco biotube effluent filter, FT0444-36. ➢ High Level Alarm/Float - Use a SJE Rhombus Level Alert or equivalent liquid level alarm, and low water/redundant off alarm.
