Michael,
The response was in draft form and I did not hit send. Thank you
for the reminder.
The NOV-202o-DV-0297 referenced SSO 202001430 that
occurred on Thursday, May 21, 2020, on Lincoln Street in West
Badin was a result of inflow and infiltration inundating the West
Badin Sewer Collection System after prolonged rains creating a
severe natural condition. Rains started on May 19, 202o, and lasted
throughout the week. Rain accumulation in Stanly as May 21,
2020, was over 4.5 inches and an addtional 3 inches of rain came
after May 21, 2020, creating excess I and I entering into the sewer
collection system. Much of the Badin's Sewer Collection System has
been rehab for many years but there still remains a substantial
amount of VCP pipe in the West Badin section of the sewer
collection system. Stanly County Utilities is currently working with
The Wooten Company to make a CDBG Grant application to find
and fix the problems in the sewer collection system for I and I
abatement. The process involves community participation in
completing income surveys and a public hearing is scheduled for
the November 16, 2020, Stanly Board of Commissioners
Meeting. We will be seeking a resolution to seek the CDGB grant
funding to find and fix sources of I and I, specifically in the West
1

Badin section of our sewer collection system. We are very
optimistic it will be approved.
The NOV-202o-DV-0297 referenced SSO 202001431 that
occurred on Thursday, May 21, 2020, at the Deese Street Lift
Station in the Town of Richfield was a result of inflow and
infiltration inundating the Richfield Sewer Collection System after
prolonged rains creating a severe natural condition. The Town of
Richfield Sewer Collection System was acquired by Stanly County
Utilities in October 202o because the Town of Richfield no longer
had the financial capability to operate the system. Stanly County
assumed all remaining debt and assumed billing operations. The
sewer collection system is a gray water system with over 26o septic
tanks that discharged into a series of 3-inch, 4-inch and 6-inch
gravity collection lines that flow to eight effluent pump stations
with the Deese Street Pump Station, a larger duplex non -clog
submersible pump station, being the collector station for the entire
system. Stanly County Utilities is aware of the inflow and
infiltration issues with this collection system and have applied for
an NCDEQ-DWI grant/loan to find and fix sources of inflow and
infiltration within the system. Much of the I and I, we believe is
coming from the individual septic tanks that are drinking
groundwater when the soil becomes saturated in high water table
periods bought about by prolonged or repeated rain events. The
Wooten Company applied for an NCDEQ-DWI grant/loan
application on September 30, 2020, and we await their decision on
approval. If we do not receive approval, we will look for other
sources of internal funding to upgrade the collection system.
Thanks,
Duane

Event Summary
✓ Over the past 48-72 hours, 2 to 5 inches of rain has fallen across central NC.
✓ An additional 1 to 2 inches of rain, with locally higher amounts is possible through the evening and early
overnight hours, which will result in a continued threat of Flash Flooding. Of most concerning will be
this afternoon and evening when expected thunderstorm development will have the potential to produce
high rainfall rates of 1 inch per hour as they move across already saturated soils.
✓ Resultant runoff could lead to minor flooding of area rivers and creeks into the weekend, especially
along the Haw, Deep River, Yadkin and Cape Fear river basins.
✓ There is also a chance for a few strong to severe storms across southern portions of Central NC this
afternoon. Damaging thunderstorm wind gusts will be the primary threat.
