Subject: Sewer Permit Submittal for Grayson Park Phase 3A
Gravity Sewer System to Serve 140 Lots
Modification to (W00029667)
Brunswick County, North Carolina
Dear Mr. Lewis:
Cape Fear Engineering, Inc. (CFE) is requesting a modification to the wastewater collection system for
Grayson Park. This request is for the Phase 3A of the development which proposes 140 lots to be served via
gravity sewer main. The permit will be modified accordingly for the future phases of development.
Flow from this project will go to downstream sewers permitted under WQ0029667 and will eventually
discharge to the Belville Wastewater Treatment Facility (NC0075540). The flow allocation for the currently
proposed Phase 3A is 29,400 gpd. A FTSE form will not be required as the February 12, 2018 permit
modification applied the approved flow reduction to the existing permit and flow is available (see attached
spreadsheet).
For your review we have provided the following:
• Fast Track Sewer System Extension Application (FTA 06-21)
• Existing Sewer Pennit (WQ0029667)
• Grayson Park Flow Allocation Tracking Table
• Engineering Narrative
• Construction Plans
I trust that the information provided is sufficient for your approval of this modification request and execution
of the permit application. Please let us know when the signed application is ready to be picked LIP. If you have
any questions or need any additional information, please contact me directly.
Sincerely,
Mason Manhertz, P.E.

GENERAL:
Grayson Park is a community located along Maco Road (NC Hwy 87) approximately 1.3
miles northwest of the intersection of Maco Road and NC Hwy 17 in the Town of
Leland, Brunswick County North Carolina.
This submittal includes improvements to serve 22 single family residential lots and 118
multifamily units in Phase 3A of the development.
Wastewater flows from proposed Phase 3A will be conveyed through a new gravity
sewer system. Flow will go to a downstream sewer system (Existing Phase 2A) permitted
under WQ0029667. Ultimately wastewater flows will discharge to the Belville WWTP
(NC0075540).
The proposed gravity sewer will consist of approximately 3,850 LF of 8-inch SDR-35
PVC pipe and approximately 45 LF of 8-inch ductile iron pipe.
A pump station is planned for future sections of Grayson Park Phase 3. The receiving
force main from the pump station will tie into SSMH #9. As such, approximately 85 LF
of the proposed force main will be installed during construction of Phase 3A.
WASTEWATER PROJECTION:
A flow reduction was approved for the Grayson Park Development under permit
WQ0029667 on February 12, 2018. The addition of Phase 3A will be a permit
modification and will apply the flow reduction of 210 GPD/unit. Thus, the projected
ultimate average flow from the 140 proposed service connections is anticipated to be
29,400 GPD. The sewer permit includes enough available flow for Phase 3A, therefore, a
FTSE form is not required.
SYSTEM DESIGN:
Gravity System:
The gravity sewer system for the project has been sized in accordance with the
requirements set forth in "NCDENR Minimum Design Criteria for the permitting of
Gravity Sewers".
TREATMENT FACILITY:
The proposed wastewater flow of 29,400 GPD for Phase 3A of the Grayson Park
development is covered under existing permit WQ0029667. Therefore, no additional flow
is being requested from the Belville Wastewater Treatment Facility.

OPERATION AND MAINTENANCE:
Brunswick Regional Water and Sewer (H2GO) will be responsible for the operation and
maintenance of the sanitary sewer system.
