INSTALLATION GENERAL NOTES
1.DESIGN ASSUMES A MINIMUM DYNAMIC PRESSURE AVAILABLE FOR THE IRRIGATION
SYSTEM (PER ENGINEER ) OF 90 PSI, AT A MAXIMUM PEAK FLOW OF 80 GPM AT THE
EXISTING NON-POTABLE 6-INCH POINT-OF-CONNECTION (POC). VERIFY PRESSURE AND
FLOW ON SITE PRIOR TO CONSTRUCTION. CONTACT GENERAL CONTRACTOR OR OWNER'S
REPRESENTATIVE IMMEDIATELY IF FLOW OR PRESSURE ARE LOWER THAN LISTED ABOVE.
1.1.IRRIGATION TAP, METER, SERVICE LINES, AND BACKFLOW SHALL ALL BE THE SAME
SIZE, AS STATED ABOVE.
1.2.IRRIGATION IS CONNECTED DOWNSTREAM OF THE 6-INCH NON-POTABLE LINE AS
INDICATED. IRRIGATION IS DESIGNED TO UTILIZE ONLY 70 GPM FROM THE 2-INCH
METER, BY OTHERS.
1.2.1.AVAILABLE PUMP STATION PRESSURE OBTAINED IS 90 PSI AT ELEVATION 4890'.
2.ALL MAINLINES SHALL BE INSTALLED AT LEAST 5' FROM CENTER OF TREES, WHERE
POSSIBLE. DESIGN IS SHOWN FOR CLARITY, THUS MAINLINE ROUTING IN FIELD MAY LOOK
SLIGHTLY DIFFERENT THAN DEPICTED IN DRAWINGS.
3.CONTRACTOR SHALL CREATE A LAMINATED CONTROLLER CHART ADHERED TO THE
INSIDE OF THE CONTROLLER COVER OR A LAMINATED COLORED CONTROLLER MAP.
4.CONTRACTOR SHALL BECOME FAMILIAR WITH THE SPECIFICATIONS AND
INSTALLATION DETAILS FOR THIS AND RELATED WORK PRIOR TO CONSTRUCTION. FOR
CLARIFICATION, CONTACT IRRIGATION DESIGNER PRIOR TO CONSTRUCTION.
4.1.UPON FINAL ACCEPTANCE, CONTRACTOR SHALL TURN OVER REQUIRED
ADJUSTMENT KEYS INCLUDING BUT NOT LIMITED TO CONTROLLER ENCLOSURE AND
BACKFLOW ENCLOSURE KEY, LOCKING VALVE BOX KEYS, QUICK COUPLER KEYS, GATE
VALVE KEY, SPRINKLER HEAD AND NOZZLE ADJUSTMENT KEYS.
4.2. UPON FINAL ACCEPTANCE, CONTRACTOR SHALL TURN OVER SPARE PARTS
PERTAINING TO INSTALLED SYSTEM: BACKFLOW WINTERIZATION INSERT, TWO OF
EVERY HEAD AND NOZZLE (ROTOR NOZZLE TREE INCLUDED), ONE RCV DIAPHRAGM,
ETC.
5.COORDINATE UTILITY LOCATES OF UNDERGROUND UTILITIES PRIOR TO
CONSTRUCTION ("811-CALL BEFORE YOU DIG") .
6.IF DISCREPANCIES ARE NOTED IN THE FIELD BETWEEN SITE CONDITIONS AND
PROVIDED DESIGNS, CONTRACTOR SHALL NOTIFY OWNER'S REPRESENTATIVE OR
GENERAL CONTRACTOR IMMEDIATELY. DO NOT PROCEED WITH THE INSTALLATION OF
THE IRRIGATION SYSTEM IF SUCH DISCREPANCIES IN THE FIELD AFFECT THE PROVIDED
DESIGN, DETAILS, OR SPECIFICATIONS.
7.ALL IRRIGATION COMPONENTS (MAINLINE, WIRES, LATERAL LINES, ETC.) SHALL BE
INSTALLED IN LANDSCAPED AREAS WHENEVER POSSIBLE, EVEN THOUGH SAID IRRIGATION
COMPONENTS MAY BE SHOWN OUTSIDE PLANTING AREAS FOR CLARITY.
8. AVOID CONFLICTS BETWEEN THE IRRIGATION SYSTEM, PLANTING MATERIALS, AND
ARCHITECTURAL FEATURES WHENEVER POSSIBLE. COORDINATE POTENTIAL RELOCATION
OF BOULDERS AND TREES IN TURF AREAS WITH LANDSCAPE ARCHITECT PRIOR TO
SPRINKLER LAYOUT. IF LANDSCAPE MATERIAL CANNOT BE RELOCATED,ADDITIONAL
SPRINKLERS MAY BE REQUIRED.
8.1.WHERE POSSIBLE, MAINTAIN 3'-5' DISTANCE FROM CENTER OF TREE TO MAINLINE
AND WIRES. VALVE BOXES SHALL BE AT LEAST 3' FROM TREE CENTER. MAINLINE
ROUTING AND VALVE LOCATIONS ARE SHOWN FOR CLARITY AND MAY BE SHOWN
WITHIN THE 3'-5' RANGE NOTED ABOVE.
9.NON-POTABLE WATER IS BEING UTILIZED ON THIS SITE. INSTALL ALL MAINLINE PIPE
WITH CHRISTY ID WARNING TAPE READING "NON-POTABLE WATER, DO NOT DRINK".
INSTALL AT LEAST 6" ABOVE MAINLINE PIPE.
9.1.SCRUBBER VALVES SHALL BE INSTALLED PER DETAILS.
9.2.PURPLE HANDLES ON ALL VALVES SHALL BE INSTALLED PER DETAILS.
9.3.NON-POTABLE WARNING SIGNS SHALL BE POSTED ON SITE HEAR GATHERING
PLACES. INSTALL PER COLORADO HEALTH CODES.
9.4.BACKFLOW PREVENTOR IS NOT NECESSARY.
10. CROSS FITTINGS ARE NOT ALLOWED, ONLY STANDARD TEES AND ELBOWS.
11.CONTRACTOR SHALL INSTALL NOZZLES PER PLAN, UNLESS IRRIGATED AREA
CHANGED IN SIZE OR PLANT MATERIAL TYPE CHANGES. IF NOZZLE CHANGES ARE
REQUIRED AND ARE SIGNIFICANT IN SIZE, CONTRACTOR SHALL CONTACT IRRIGATION
DESIGNER FOR APPROVAL.
12.CONTRACTOR SHALL FIELD LOCATE ANY EXISTING SLEEVES ON SITE PRIOR TO
CONSTRUCTION WITH THE AID OF THE GENERAL CONTRACTOR. MISSING SLEEVES SHALL
BE REPORTED IMMEDIATELY. NEW SLEEVES SHOWN ON PLANS ARE REQUIRED FOR BOTH
PIPING AND ELECTRICAL WIRING AT EACH HARDSCAPE CROSSING. COORDINATE
INSTALLATION OF SLEEVING WITH OTHER TRADES. ANY PIPE OR WIRE WHICH PASSES
BENEATH EXISTING HARDSCAPE WHERE SLEEVING WAS NOT INSTALLED WILL REQUIRE
HORIZONTAL BORING BY THE IRRIGATION CONTRACTOR.
13.INSTALL ALL ELECTRICAL POWER TO THE IRRIGATION CONTROL SYSTEM IN
ACCORDANCE WITH THE NATIONAL ELECTRIC CODE AND ALL APPLICABLE LOCAL
ELECTRIC UTILITY CODES.
14.THE FOLLOWING SHOULD BE NOTED REGARDING PIPE SIZING: IF A SECTION OF
UNSIZED PIPE IS LOCATED BETWEEN THE IDENTICALLY SIZED SECTIONS, THE UNSIZED
PIPE IS THE SAME NOMINAL SIZE AS THE TWO SIZED SECTIONS. THE UNSIZED PIPE
SHOULD NOT BE CONFUSED WITH THE DEFAULT PIPE SIZE NOTED IN THE LEGEND.
14.1.MAINLINE PIPE SIZES MAY VARY THROUGHOUT PROJECT. EACH MAINLINE LEG
IS SIZED TO ACCOMMODATE LARGEST VALVE ON THAT LEG. STATED SIZE IN LEGEND
MAY NOT BE THE LARGEST SIZE ON PLANS.
15.TWO-WIRE CONTROL CABLE DOES NOT REQUIRE ADDITIONAL SPARE WIRES TO BE
ROUTED WITH MAINLINE.
15.1.TWO-WIRE CONTROL SURGE ARRESTORS SHALL BE INSTALLED PER
MANUFACTURER'S RECOMMENDATIONS. ARRESTORS ARE NOT DEPICTED ON PLANS
16.TREES IN TURF ARE NOT IRRIGATED BY DRIP SYSTEM. DRIP LATERAL ROUTED NEAR
TREES IN TURF ARE NOT TO RECEIVE DRIP IRRIGATION. TREES IN NATIVE SEEDED AREAS
ARE IRRIGATED ON DRIP SYSTEM.
17.VALVES FOR NATIVE SEEDED AREAS SHALL BE ON A SEPARATE PROGRAM.
18.NATIVE SEEDED AREAS ARE TO BE IRRIGATED WITH A BELOW GRADE SYSTEM BUT
UTILIZED FOR ESTABLISHMENT OF SEED. SYSTEM IS NOT INTENDED TO OPERATE BEYOND
ESTABLISHMENT.
19.NO IRRIGATION EQUIPMENT, INCLUDING BUT NOT LIMITED TO, MAINLINE, VALVES,
AND SPRINKLERS, SHALL BE INSTALLED WITHIN 3' OF NEW BUILDING FOUNDATION.
20.CONTRACTOR SHALL PROVIDE SMART CONTROLLER CHART, PER LOCAL WATER
DISTRICT OR MUNICIPALITY, INSIDE CONTROLLER DOOR.

CODE DESCRIPTION
THE IRRIGATION SYSTEM POINT-OF-CONNECTION (POC) SHALL BE
DOWNSTREAM OF THE NON-POTABLE IRRIGATION WATER TAP
AND METER AT THE APPROXIMATE LOCATION SHOWN (REFER TO
CIVIL PLANS FOR EXACT LOCATION). INSTALL ISOLATION GATE
VALVE, QUICK COUPLER, MASTER VALVE ASSEMBLY, AND FLOW
SENSOR AS INDICATED OUTSIDE OF EASEMENTS. VERIFY EXACT

FOR MAINTENANCE, AND SCREENED FROM VIEW BEHIND PLANT
MATERIAL WHERE APPLICABLE. FINAL LOCATION TO BE
APPROVED BY OWNER`S REPRESENTATIVE. CONTROLLER TO BE
INSTALLED PER NATIONAL ELECTRIC CODE.
IRRIGATION SHOWN IN HARDSCAPE FOR CLARITY ONLY. ALL
IRRIGATION SHALL BE INSTALLED IN LANDSCAPED AREA. ANY
IRRIGATION TO BE INSTALLED UNDER HARDSCAPE SHALL BE
SLEEVED.

These are to be driven into the ground in a vertical position or an oblique angle not to exceed 45 degrees at
a location 10 feet from the electronic equipment, the ground plate, or the wires and cables connected to said
equipment, as shown in the irrigation details. The rod is to be stamped with the UL logo. A 6 AWG solid

equipment ground lug as shown in the detail of page 1. The ground plate is to be installed to a minimum
depth of 30”, or below the frost line if it is lower than 30”, at a location 8 feet from the electronic equipment
and underground wires and cables.
Two (2) 50-pound bags of PowerSet [Paige Electric part number 1820058] earth contact material
must be spread so that it surrounds the copper plate evenly along its length within a 6” wide trench.
Salts, fertilizers, bentonite clay, cement, coke, carbon, and other chemicals are not to be used to
improve soil conductivity because these materials are corrosive and will cause the copper electrodes
to erode and become less effective with time.
