Agricultural and Biosystems Engineering
Do not generate more wastewater than the average daily flow (gallons per day) for which the on-site system was designed. Install a water meter to measure the volume of water being used by the household (or other facility) to determine the flow released into the on-site treatment system. If the system has a pump/lift station delivering septic tank effluent to the soil treatment unit, install an electrical event counter on each lift station. Install a water meter to measure water usage. The event counter will tally the number of pump operation cycles, which, if multiplied by the gallons pumped per cycle, will determine the amount of effluent delivered to the soil treatment unit.
