PUMP DOSING CALCULATIONS:
1. DETERMINE VOLUME OF EFFLUENT TO BE PUMPED TO LEACHING
FIELD:
DAILY FLOW = 330 GALLONS
NUMBER OF DOSES PER DAY = 10 DOSES
NUMBER OF GALLONS = 330/10 = 33 GPD
DRAIN BACK VOLUME:
2" FORCE MAIN & 2" MANIFOLD = 0.2 GALLONS
PUMPING VOLUME = DOSING VOLUME + DRAIN BACK VOLUME
PUMPING VOLUME = 33 GALLONS + 0.2 GALLONS = 33.2 GALLONS '
2. DfSCHARGE RATE:
22 TOTAL PERFORATIONS (INCLUDING VENTS) x 1.17 GPM / PERF.
� 2.5' HEAD = 25.7 GPM
3. TOTAL DYNAMIC HEAD: 9.1 FT.
4. PUMP MUST BE CAPABLE OF PUMPING AT LEAST 25.7 GPM
