Mr. Vinson,
Timmons Group is pleased to submit the following Reclaimed Water Systems — Distribution Lines Application on
behalf of The Town of Holly Springs. This application is being submitted to request the addition of the Goodwin (Yield
North) Infrastructure Phase I and II reclaimed waterline infrastructure located in the proposed development off Woods
Creek Road that connects to the Town of Holly Springs' existing reclaimed water system.
This project consists of the following components: 2,581 feet of six-inch (6") Purple PVC pipe, 60 feet of six-inch (6")
Ductile Iron pipe, 2,737 feet of twelve -inch (12") Purple PVC pipe, and 60 feet of twelve -inch (12") Ductile Iron pipe.
This reclaimed water system is designed to serve the build -out of the Yield North development. The proposed 12"
alignment along Woods Creek Road will begin just beyond the Friendship Road — Woods Creek Road intersection
with a temporary blow off assembly and extend to tie into an existing reclaimed waterline further along Woods Creek
Road owned by the Town of Holly Springs.
This project requires authorization under a 404 Nationwide permit. The permits have been approved and include The
Woods Creek Road Widening project with the NCDWR Project No. 20221757 v.2 and Certification No. 6329 as well

BackLyround
As requested by the Town of Holly Springs (Town), DMP has evaluated the feasibility of adding the proposed
Godwin (Yield North) to the Reclaimed Water System. The proposed project is in the north limits of the
Reclaimed Service Area and is along Woods Creek Road, slightly west of the Carolina Springs PUD.
Model Setun
DMP performed the evaluations utilizing the Town's reclaimed water system model in WaterCAD. The
following setup was used for the modeling:
• Reclaimed Model Setup
— Tank Water Elev: 578' (normal low, down 7 ft)
— WRF Pumps off
— SFR Lots at Typical Demand (1.83 gpm/SFR due to average lot size being approximately 15,000 SF)
(assumes 70% of SFR's are connected).
— Sequiris: 550 gpm (includes 400 gpm cooling and 150 gpm irrigation)
— WRF: 360 gpm (NPW uses + 200 gpm for RCW bulk filling)
— Twelve Oaks Pond: 500 gpm
— Ingenco: 53 gpm
— Burt Tract: Full build out active and in service (412 gpm)
— Hensley Tract: Full build out active and in service (214 gpm)
— Twelve Oaks Phase 09: Full build out active and in service (Stephenson) (150 gpm)
— Addison Subdivision: Full build out active and in service (Formerly Harris) (72 gpm)
— New Hill Road Subdivision (52 GPM)
— Carolina Springs PUD Phase 1—Areas 1-5 (296 GPM)
— Carolina Springs PUD Phase 2 —Areas 6-8 (225 GPM)
— Model Calculations: All modeling calculations were performed as a Steady State Model. Modeling
as a Steady State Model provides for worst case demand condition, meaning that all demands in
the model are active as part of the Scenario calculation.
• Godwin (Yield North)
Based on CAD drawings and PDF's provided to DMP by the Town of Holly Springs, the Godwin
Development includes multiple sites for a business/industrial park. .
The information provided to DMP was brought into the model as a backdrop. The reclaimed water line
extensions and system nodes, with corresponding elevations, were then added to the model. Nodes
within the project are estimated to be at an approximate elevation of 290 to 320 ft based on the
information provided.

At this time the extensions of the Reclaimed Water System within the development were analyzed to
provide irrigation demand to the proposed development.
Modeline Results:
Godwin was modeled as with 6" RCWL piping with new taps on the proposed 12" RCWL along Woods Creek
Road, which will be extended as part of this project. The third area is extending lines in the previously
approved Phase 1 area. The model also assumed that the developments proposed and approved prior, as
outlined under Reclaimed Model Setup, are active and in service.
Based on the above described model setup, one scenario was modeled and is described with results
summarized as follows:
Scenario 1: Base Svstem [CS PUD Ph 2, all areas)
This Scenario assumes full build out all Sub -phases in Phase 1 and all areas for Phase 2.
— Existing 6" RCWL from New Hill Road to Ivy Arbor Way
— New 12" RCWL installed from Ivy Arbor Way to Ingenco
— Existing 12" RCWL to Twelve Oaks Phase 9 (Stephenson)
— New 12" RCWL to serve Godwin
— Results: Pressures are above 45 psi, which is the target system requirement minimum pressure.
Feasible - Does meet the Project Objectives
Summary
For Godwin (Yield North), the model was setup as described above.
One scenario was modeled and pressures within the Development are satisfactory and meet the
requirements of the Town's RCW System. These results indicate that the proposed project meets the
objectives of the system.
One system component that should be monitored as part of the build -out for Godwin (Yield North) is the
impact on the previously approved Twelve Oaks Phase 09. This system was designed to be installed with
master meters, which require a 70 psi minimum, based on design information supplied to DMP at the time
of review for Twelve Oaks Phase 09. With significant demands being placed on the system adjacent to and
north of these master meters could potentially have impact on the operation of this system.

11.04 RECLAIMED WATER IRRIGATION SYSTEMS
A. GENERAL
All reclaimed water irrigation systems within public street right of way require an
encroachment agreement from the Town of Holly Springs or NCDOT prior to
installation. Plans designating the location, size, material, and depth shall be submitted
with the agreement application to the Engineering Department.
Pipe material for the irrigation mainline proposed to be used within the public right of
way shall be Schedule 40 PVC or greater. All pipe, fittings, and appurtenances shall
be purple (Pantone 522 or similar). A minimum depth of 2 feet of cover shall be
provided.
A soil evaluation is necessary in order to determine the loading rate for irrigation
permits. All development within the reclaim service area will need to complete an
independent soil evaluation prior to submitting a reclaim irrigation permit.
All reclaimed water irrigation systems are required to secure permits from the Code
Enforcement Department and the Utilities and Infrastructure Services prior to
installation and shall be inspected after installation. A separate meter is required for
irrigation systems.
For single family irrigation design, a CID, PE, or LA is required to develop the plan.
For non -single family irrigation system designs, a PE must develop the plan.
Impoundments for reclaimed water storage for large scale irrigation systems or
aesthetic/decorative water features shall be designed in accordance with 15A NCAC
02U — Reclaimed Water.
Service lines from mainline tap to the meter are installed and identified per the Town
of Holly Spring's Standard Details. There shall be no direct cross -connection between
potable and reclaimed water supplies.
2015 ED&CS 11-15 Supp #10 June 2024

B. DESIGNS
Sprinklers chosen and located to maintain the following setbacks from the irrigation
area to the following features:
1.) 25 feet from surface waters [perennial and intermittent streams, wetlands] not
classified as tidal salt waters or high -quality water (SA).
2.) 100 feet from surface waters [perennial and intermittent streams, wetlands]
classified as tidal salt waters or high -quality water (SA).
3.) 100 feet from any water supply well (not including monitoring wells).
4.) Sprinklers located on a steep slope have check valves installed on all the heads on
that irrigation zone.
5.) No mainlines or valves shall be allowed within the utility/devil strip. Laterals will
be allowed and shall be placed within 1 ft of sidewalk.
6.) The zoning of the irrigation system must allow that plants with different water
requirements (such as grass and shrubs) are on separate zones. In addition, the
irrigation design should consider the different microclimates found in most landscapes
(such as north facing grass areas vs. south facing grass areas) and separate those
microclimates into zones. These zoning practices may add slightly to the installation
cost of an irrigation system, but can have a dramatic effect on system efficiency.
7.Guidelines on pressure at the head/emitter: Spray Heads 20 to 35 psi; gear rotors 60
psi or less; impact rotors 60 psi or less; drip emitters 40 psi or less.
8.Large commercial systems which have the potential to place undue burdens (demand
or pressure requirements) on the Town of Holly Springs' public reclaimed distribution
system must include on -site storage and/or pumping facilities. This determination will
be made by the Executive Director of Utilities and Infrastructure Services. Design,
operation, and maintenance of such on -site facilities shall be the sole responsibility of
the applicant. These additional facilities must be designed in accordance with 15A
NCAC 02U — Reclaimed Water.
9.Rain sensors must be installed to reduce the likelihood of overwatering. Rain sensors
are required to remain in service at all times to prevent overwatering and/or ponding of
reclaimed water.
C. STREET CROSSING
2015 ED&CS 11-16 Supp #10 June 2024

All irrigation line street crossings shall be contained within a ductile iron or steel casing
pipe. The Town of Holly Springs may, in some instances, permit irrigation systems
installed in the medians of Town -maintained roadways. These systems must also have
french drains installed behind the curb and gutter and piped to a storm drainage
collection system. These systems shall be allowed only when some permanent
mechanism is established for the private perpetual maintenance of the system(s).
D. HOSE BIDS
Hose bibs are not permitted for the reclaimed water system.
E. RAIN SENSORS
Rain sensors must be installed to reduce the likelihood of overwatering. Rain sensor
must remain in operation to prevent ponding or runoff.

B. TESTING
1. Hvdrostatic Testing
2015 ED&CS 11-17 Supp #10 June 2024

a) All valves in the Town of Holly Springs reclaimed water system shall be
operated by the Town of Holly Springs. A section of reclaimed water main
which is to be hydrostatically tested shall be slowly filled with water at a rate
which will allow complete evacuation of air from the line. Hand pumps shall
not be used for the pressure testing of reclaimed water mains. Taps used for
testing purposes shall be removed after testing. The corporation stops shall be
removed and a threaded tapered plug shall be installed on the line.
When approved by the Town of Holly Springs, the Contractor may utilize
potable water or reclaimed water via an approved hydrant meter and RPZ
assembly for testing and disinfection of new reclaimed mains which are not
physically connected to a live reclaimed water supply. Once reclaimed water
has been introduced into the system no direct connection to potable water will
be allowed and an approved air gap assembly must be used.
b) Any measured leakage not within the allowable limits as specified in the
following table shall require repair of the reclaimed water main and additional
testing until the standards are met. For pipe sizes other than those shown, the
Contractor shall test within the allowable leakage amounts as specified by

opening the control valve and systematically manipulating blowoffs and
taps at the reclaimed water main extremities. All reclaimed water leaving
the system during this test must be disposed of through either an approved
use or sent to the sanitary sewer. The HTH solution must be pumped in at
a constant rate for each discharge rate so a uniform concentration will be
produced in reclaimed water mains.
iv. HTH solution shall remain in reclaimed water mains for no less than 24
hours or as directed by the Town of Holly Springs' Inspector.
v. Extreme care shall be exercised at all times to prevent the HTH solution
from entering existing reclaimed water mains.

a) Free residual chlorine after 24 hours shall be at least 10 ppm or the Town of
Holly Springs' Inspector will require that the lines be re -chlorinated.
b) Flushing of reclaimed water mains may proceed after 24 hours, provided the
free residual chlorine analysis is satisfactory. Reclaimed water leaving the
system because of line flushing must be returned to a sanitary sewer. Flushing
shall be continued until an orthotolidine check (or other method approved by
the Town of Holly Springs) shows that the reclaimed water mains contain only
the normal chlorine residual. Samples for bacteriological analysis shall be
collected by the Town of Holly Springs' Inspector 24 hours after flushing is
completed. The Contractor shall furnish the sample bottles, the testing agency
and such help as may be required to secure these samples. The Contractor shall
also submit the test results to the Town of Holly Springs' Development
Inspector.
