Wastewater Irrigation System
Durham County
Dear Mr. Kershner,
Staff of the NC Division of Water Resources (DWR), Water Quality Regional Operations Section
inspected the subject wastewater irrigation system on May 15, 2019. I wish to thank Curtis Tyree and Brian
Murphy for their help during the inspection. The purpose of the visit was to conduct a compliance
inspection of the system.
Curtis Tyree is the ORC and Vinny Shea is the Backup. Brian Murphy will also be backup when
gets his certification.
On the day of the inspection, the freeboard was at 29 ft in the facultative lagoon and 2.8 ft in the
storage lagoon. There is a fence with signs around the facility and the berms were mowed. The aerator is
currently not working. Sludge levels were reportedly Iast checked in 2012. The facultative lagoon had 8"
of solids and the storage lagoon had 1" of solids.
The chlorinator was in good condition. Staff report that maintaining 2 ppm of chlorine is easy with
the system in place. The chlorine contact chamber is also in good condition. The pump and controls were
in working condition.
Sprayheads still clog with frog bones from frogs in the chlorinator. Plans are still in the works to
create a screen to exclude them. The system generally pumps 150-200 gpm.
The Iift station pumps and controls at the park ranger's house and other sites were tested and found
to be in working order. The septic tank at the ranger's house was Iast pumped fall of 2013. Septic tank
solids are checked twice a year.
Lift station pump run times are checked daily. Little work has been needed on the lift stations other
than clearing check valves.
The facility is applying between 2 and 10" of water to the sprayfields of the 31" permitted
maximum. Fields are sometimes irrigated for 6 hours or more, but runoff reportedly does not occur. New
seals have been installed in some of the drainfield piping and more seals are on order.

A soil sample was collected in 2018. No lime was recommended. Pump calibrations are done by
drawdown tests. The flow meter was calibrated by Altantic Environmental in January 2019.
Records have been submitted complete and on time. Facility records were in good order.
On the day of the inspection, the facility appeared to be operating in compliance with permit
conditions.
