The system I designed in 1993 anticipated that the,flow to the drainfield would be approximately 100 gallons per day. Based on recent EPA Risk Management Research for On Site Waste Water Treatment and Disposal Systems (Copy of Table Enclosed) a waste water flaw of 15 gallons per day per employee would be the anticipated flow to the system. Based on a flow of 15 gallons per day per employee, the system should be able to process the waste from 6 employees with no problems. YouilLG- Pat McCullough, 1E President, ESA Inc.
