WWTF Flow Study, November 2021
Compiled by Larry Chilton, ORC
This is the flow study as required by our permit. It consists of data from November 2020 through
October 2021.
Included in this report are the calculations for all the sewer accounts associated with the water district.
A description of the source of the influent is also included.
Included in this packet are copies of the NDMR's for the past 12 months. Also included are spreadsheets
showing each account's monthly total gallons and the monthly daily averages.
There is a spreadsheet showing the totaled daily averages from each account compared to our influent
meter numbers. There is a spreadsheet showing the Effluent meter calculations.
The flow is all domestic sewer consisting of; 3 Schools, 4 manufacturing facilities, 2 NCDOT rest stops,3
small offices, 2 Churches, 1 Retreat Center, 3 private residences, 2 Restaurants- 1 with a grocery store
attached. We have Inflow and Infiltration that is known to enter our system upstream of the headworks
of the treatment plant. We have been told that the old Luck's cannery buildings have roof and storm
drains tied to the main influent line to our WWTF. (The current WWTF was part of the bean cannery
when Luck's was still in operation).
This flow study has revealed that the Influent Meter at the WWTF is not accurate. This study revealed
over the past 12 months the meter is off by 2,871 gallons per day, to the negative. We are receiving
more gallons per day than the influent meter is showing. The Effluent meter spreadsheet shows the
actual throughput number to our sixteen zones which accounts for I&I and rainfall that falls directly into
the open top digester, c12 chamber, and storage lagoon.
I can find no documentation on file for the current influent meter which was apparently not kept by the
previous ORC. When I contacted a certification analyst about calibration and recertification, he stated
that the unit is outdated and would need to be replaced.

Renovations and upgrades at the WWTF are planned for the near future. The water district has been
awarded COVID-19 money from the Randolph County Commissioners for the purpose of replacing and
upgrading the current treatment facility. This funding will allow us to provide adequate wastewater
treatment and allow this area of our county to expand and grow with the expanded capacity to treat
more flow. An engineering firm has been hired by the water district and is currently in the design phase
of the upgrades. The discussed plans are to install a new package treatment plant, headworks, and a
new influent meter (I have specified a Totalizer style meter). We will have to redirect storm drains away
from the treatment system which is part of the new headworks design. Plans and specifications will be
submitted to the State for approval when the engineer completes his design.
We welcome any feedback and if you require further information, you can contact Larry Chilton (ORC)

* Gallons Irrigated Daily Average column is for figuring purposes only,
we DO NOT irrigate daily, during rain events, or when irrigating would
cause runoff. Irrigation only occurs on average 2-3 times per week
depending on the amount of precipitation received.
*This column gives a better idea of how rain events effect our
throughput at the facility. The open tops on the digester, c12 chamber,
and lagoon combined with I&I greatly adds to our GPD average.
