Septic Pump / Dose Tank Volume
Net dose per cycle, pumped volume per cycle and per day, and the dose-to-void ratio for a timed-dose pressure-distribution field. Per the USEPA Onsite Wastewater Treatment Systems Manual; the dose count and float settings on the permit drawing govern.
Formula and source
Net dose = daily flow / doses per day; pumped per cycle = net dose + drainback; pumped per day = pumped per cycle x doses; dose-to-void ratio = net dose / drainback (target >= 5).
