The conditions observed during this site evaluation indicate that the area around the evaluated test holes is not capable of supporting a standard system due to depth to rapidly draining material.

Peak sewage flow into the system is limited to a maximum of 450 gallons per day, with an average sewage flow of not more than 225 gallons per day. Premature failure of the treatment system may occur if either of these flow quantities is exceeded.
