1. ENGINEER SHALL INSPECT WHEN THE REQUIRED EXCAVATION IS COMPLETE.
2. WALL LOCATION TO BE STAKED OUT PRIOR TO CONSTRUCTION.
3. ENGINEER SHALL INSPECT INSTALLATION OF VERSA-LOK WALLS AND IMPERVIOUS BARRIER.
PRIOR TO BACKFILL
4. ENGINEER SHALL INSPECT WHEN CLEAN FILL WITH A PERCOLATION RATE
OF LESS THAN TWO (2) MINUTES PER INCH HAS BEEN PROPERLY DEPOSITED.
5. ENGINEER SHALL INSPECT WHEN THE COMPONENTS OF THE SEPTIC SYSTEM
AND THE PUMP MECHANISMS HAVE BEEN INSTALLED, PRIOR TO BACKFILL.
6. ENGINEER TO INSPECT FINISH GRADE AROUND VERSA-LOK RETAINING WALL.
PRESSURE DOSE SPECIFICATIONS
PERFORATION SIZE: 1/4" DIAMETER
PERFORATION SPACING 5' O.C.
LATERAL DIAMETER 1.5"
MANIFOLD DIAMETER 2"
PERFORATIONS ON ADJACENT LATERALS
TO BE STAGGERED.
PUMP DOSING CALCULATIONS
1. DETERMINE VOLUME OF EFFLUENT TO BE
PUMPED TO WASTEFLOW DRIPLINES
DAILY FLOW = 550 GALLONS
NUMBER OF DOSES PER DAY = 6t
NUMBER OF GALLONS = 550/6 = 92 GALLONS
DRAIN BACK VOLUME
2" FORCE MAIN & 2" MANIFOLD = 1 GALLONS
PUMPING VOLUME = DOSING VOLUME + DRAIN BACK VOLUME
93 GALS. = 1 GALS. + 92 GALS.
2. DISCHARGE RATE
33 GPM ® 11 FT OF HEAD
