minute with 30 feet of head to the drain field. The control panel selected should be capable of controlling both pumps with alarms. • Peat Filer—(2) Puraflo Peat Biofilter pods. Install according to manufacturer's detail. • Drain Field—Excavate the drain field trenches as depicted on Figure 2 when the soil is less than the plastic limit to prevent smearing and compacting. Installer is responsible for determining if the soil is below the plastic limit prior to excavation. Depth of excavation shall be to the elevations given on Figure 2, scarified and leveled. Place Quick4 High Capacity Infiltrator Gravelless Chambers in the trench bottom connected by gravity drop boxes. • Grading - Back fill with native soil, seed for cover, and mulch for erosion control ASAP after installation. Create positive drainage away from the septic tank and drain field, allow for soil settling. Do not allow channeled runoff over the drain field; create drainage swales along the outer edges of the drain field to prevent excess runoff on the drain field. G.
