Subject: Sewer Flow Reduction Approval
ONWASA- WQCS00275
Onslow County
Dear Mr. Lohr:
On September 23, 2024, the Division of Water Resources (Division) received a request to
transfer the ownership of the January 11, 2023, approval for an adjusted daily sewage flow
rate (flow reduction) that would apply to the sewer collection system permitted under
WQCS00275, which was originally issued to Pluris, LLC and will have tributary flow to the
ONWASA treatment system permitted under WQ0005849. A daily design sewer flowrate of
80 gallons per day per bedroom per residential unit was originally utilized. Both permits
WQCS00275 and WQ0005849 have been transferred to ONWASA from Pluris, LLC, per the
Division's ownership change process.
In accordance with 15A NCAC 02T .0114(f) (1&2), the Division has evaluated the request
and based on the data submitted, the Division hereby approves for use by ONWASA an
adjusted daily sewage flow rate with the following conditions:
The flow reduction is applicable to the portion of residential single-family dwelling
units located in the WQCS00275 sewer service area that were not connected and
tributary to the ONWASA collection and wastewater treatment system, prior to
January 11, 2023.
The minimum design sewer flow for future one (1) bedroom dwelling unit shall be
75 gallons per day and for two (2) bedroom dwelling unit connections shall be 130
gallons per day.
Each additional bedroom above two -bedroom units shall increase by 65 gallons per
day per bedroom.
