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 appurtances 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 Ioading rate for irrigation
permits. A soil evaluation has been completed for Green Oaks Parkway median and
initial lots of the Twelve Oaks Subdivision which specified a maximum rate of 0.5
in/hr. This only applies to this small area. Any design outside of this area will need
to complete an independent soil evaluation.
All reclaimed water irrigation systems are required to secure permits from the Code
Enforcement Department and the Department of Engineering 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/dccorative 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.
FINAL 2015 11-15 Supp 12016
Supp # 2 Aug. 2017

B. DESIGNS
Sprinklers chosen and located to maintain the following setbacks from the irrigation
area to the following features:
a. 25 feet from surface waters (perennial and intermittent streams, wetlands) not
classified as tidal salt waters or high quality water (SA).
b. 100 feet from surface waters (perennial and intermittent streams, wetlands
classified as tidal salt waters or high quality water (SA).
c. 100 feet from any water supply well (not including monitoring wells).
d. Sprinklers located on a steep slope have check valves installed on all the heads on
that irrigation zone.
e. No mainlines or valves shall be allowed within the utility/devil strip. Laterals will
be allowed and shall be placed within I ft of sidewalk.
f. 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.
g. 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.
h. 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 Director of Engineering.
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.
C. STREET CROSSING
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 BIBS
Hose bibs are not permitted for the reclaimed water system. Rain sensors must be
installed to reduce the likelihood of overwatering.
