Svstem Specifications <br /> Existing tanks & pump to be inspected and re-used if OK <br /> There are 2 — 4" PVC, 1 — 4" D.T., & 1 - 10" PVC drain pipes that will <br /> need to be extended under new mound and day lighted beyond the down <br /> slope edge. The drain tile will need to be solid PVC all the way across <br /> the mound to prevent effluent from being transported out of the mound. <br /> Pump Tank: <br /> • Plumbing shall be run up into riser and back down with a 1/4" <br /> drain back hole. <br /> • Floats are to be installed on a float tree, separate from the <br /> piping connected to the pump. <br /> • A 2.5" Electrical conduit is to be used. <br /> • The 2" force main sha11 be sleeved with 4" sch 40 and sealed <br /> with 4x2 Fernco, from the pump tank to original soil. <br /> A "Zabel" PDS-PF-1.5/2.0 Pressure Filter or a "Sim-tech" Pressure <br /> Filter is to be installed in the supply line in the pump chamber, and to be <br /> easily accessible from the ground surface for cleaning. (The pump alarm <br /> will sound when this filter clogs) <br /> If a "Pressure Filter" is not best suited an "Effluent Filter" may be <br /> insta.11ed on the outlet of the second tank. This will require a filter alarm <br /> or an annual cleaning program. <br /> Plastic bolt down manhole covers are to be used and left at grade level <br /> for maint�nance access. <br /> Blowout valves are to be installed on the end of all pressurized laterals. <br /> These will need to be in a protective housing and accessible from <br /> surface grade. <br />
