This guide covers the basics of design, installation, and maintenance for Rain Bird’s XF Series Dripline.. Included are design steps, technical data, installation layouts and design details to assist in the design of the more common dripline applications..
A low volume irrigation system typically applies water slowly, at low pressure, at or near the root zones of plant material.. Whether referred to as Drip, Xerigation®, micro irrigation, or low volume, these systems feature emission devices that apply water in gallons per hour (GPH) or liters per hour (L/HR) as opposed to the gallons per minute (GPM) or liters per minute (L/MIN) of a conventional overhead spray irrigation system.. Low-volume irrigation can greatly reduce or eliminate water waste while promoting healthier plant growth because you can:
•Match the amount of water applied to the specific need of each plant
•More closely match the application rate to the soil’s infiltration rate
•Apply water directly to the root zone, reducing overspray and evaporation
Low-volume systems also reduce or eliminate runoff on walks and paved areas, and overspray onto windows, fences, pavement and walls.. The Rain Bird Xerigation® line of drip products offer a full range of water-saving choices for both turf and non-turf landscape applications, including control zone components, dripline, fittings, blank tubing, emission devices and tools..
Use of dripline is a preferred method in many low-volume irrigation applications.. Rain Bird’s XF Series Dripline has Rain Bird designed and manufactured emitters that provide pressure compensation for precise flow control throughout the zone..
XF Series Dripline is made with advanced polymers that provide kink-resistance and reduce coil memory for easier installation.. With emitter flow rates of 0..4 GPH, 0..6 GPH, and 0..9 GPH
(1..6 L/HR, 2..3 L/HR, and 3..4 L/HR) and emitter spacing of 12” and 18” (0..30 m and 0..45 m) the XF Series provides a full product line to meet the needs of any application..
The Rain Bird XF Series of dripline products consists of:
•XFD –for on-surface applications
•XFCV for on-surface, sloped applications
•XFS with Copper Shield™ Technology
–for subsurface applications
•XFS-CV with Heavy Duty Check Valve
–for on-surface, subsurface and sloped applications

LEED LIBRARY
DESIGN & TECHNICAL RESOURCES
WHAT IS LEED?
The Leadership in Energy and Environmental Design (LEED) Green Building Rating System™ is a point rating system devised by the United States Green Building Council (USGBC) to evaluate the environmental performance of a building over its life cycle and to encourage market transformation towards sustainable design.. LEED is the nationally recognized benchmark for the design, construction, and operation of high performance green buildings.. LEED provides building owners and operators with the tools they need to have an immediate and measurable impact on their buildings’ performance.. LEED promotes a whole-building approach to sustainability by recognizing performance in five key areas of human and environmental health: sustainable sites, water savings, energy efficiency, materials selection, and indoor environmental quality..
Detailed information on obtaining credits and the project certification process is available from the USGBC on their website: www..usgbc..org..
•WATER EFFICIENCY CREDIT 1.1
•WATER EFFICIENCY LANDSCAPING: Reduce by 50% 2 points
Intent
Limit or eliminate the use of potable water, or other natural surface water resources available on or near the project site, for landscape irrigation..
Requirements
Reduce potable water consumption for irrigation by 50% from a calculated mid-summer baseline case.. Reductions shall be attributed to any combination of the following items:
•Plant species factor
•Irrigation efficiency
•Use of captured rainwater
•Use of recycled wastewater
•Use of water treated and conveyed by a public agency for non-potable uses..
Rain Bird Notes
The designer on the LEED project will need to provide an irrigation plan and legend, as well as calculations, a description of the baseline, and cut sheets of the irrigation system demonstrating how water consumption is reduced by 50%..

SECTION 1:
Introduction
Dripline irrigation can greatly reduce or eliminate water waste while promoting healthier plant growth for the following reasons:
•Match the water application to the specific needs of each plant
•More precisely match the application rate to the soil’s infiltration rate
•Apply water directly to the root zone to reduce overspray and evaporation
•A properly designed and installed dripline irrigation system can be over 90% efficient
There are many advantages of dripline irrigation that can provide solutions for difficult-to-irrigate landscape areas including:
•Narrow turf areas
•Curved narrow landscape areas
•Sloped areas
•Subsurface turf irrigation applications
•Parking lot islands
•Steep sloped areas
Other benefits of on-surface or subsurface Drip Irrigation:
•Eliminate runoff on walks and paved areas
•Prevent overspray onto windows, walls and fences
•Increase watering uniformity
•Reduce susceptibility to vandalism
•Promote healthy plant growth

PREPERATION FOR DESIGN
Dripline system design follows many of the same rules as spray and rotor design.. Similar design factors must be considered, such as point of connection, static and operating pressures, flow rates, and plant material..
A dripline system when properly designed and installed will deliver full irrigation coverage to the planted area.. A dripline system is normally divided into zones.. A typical zone contains a water source, a control zone (valve, filter, and pressure regulator), and the dripline with connection fittings..
During the preparation for design you will gather essential information to design the dripline system:
•Obtain or draw a scaled plan of the site to be irrigated
•Identify all of the slopes on the plan
•Determine the types of plants to be irrigated (groundcover, shrubs, turfgrass, and trees)
•Identify the type of soil (Clay, Loam, Sand)
•Identify the type of water from the water source (potable, non-potable, well, surface water, etc)
•Identify static and operating pressures, and volume available from the water source
•Select appropriate system components for installation

The objective of a well-designed dripline system is to create an even wetting pattern of water in the soil throughout the planting zone. There are four factors to consider for planting areas to create an even wetting pattern:
•Soil type (Clay, Loam, Sand)
•Emitter flow rate: 0..4 GPH, 0..6 GPH or 0..9 GPH (1..6 L/HR, 2..3 L/HR or 3..4 L/HR)
•Emitter spacing: 12” or 18” (0..30 m or 0..45 m)
•Lateral spacing (distance between the dripline rows)
SOIL TYPE TEST
1.Remove 1 to 2 cups of soil from the zone to be irrigated..
2.Place into a glass jar, like a mason jar..
3.Fill the jar half way with water.. Shake and let sit for
2 hours so the particles can settle.. The heavier sand particles will settle to the bottom, then silt, then clay on top..
4.Measure the combined height of all three layers of the soil then the height of each layer; divide the height of each layer by the total height to figure out the percentage of each soil in the jar..
5.Apply these figures to the “Soil Classification” chart..
In the example, now you know the landscape soil is silt loam..

SECTION 3:
Determine Dripline Specifications
SECTION 3: DETERMINE DRIPLINE SPECIFICATIONS
CHOOSE THE EMITTER FLOW RATE, SPACING BETWEEN EMITTERS, AND SPACING BETWEEN ROWS
To determine the specification for the emitter flow rate and emitter spacing for the XF Series Dripline, follow the column under the proper soil type for your application to find the emitter flow and emitter spacing..
Table 2 gives recommended emitter flow rates and spacing for three basic soil types.. If the soil type is not known, or if there is a good chance that there will be many different types of soil at the site, use the shortest distance between emitters and rows from the table to be sure that the root zone is well irrigated.. If there is heavy loam or clay subsoil, these soil types will reduce the downward flow of water in the soil and allow for wider lateral spacing between rows..

Note: These are general guidelines, field conditions may require modification to emitter flow rate, emitter spacing and lateral spacing. XF Series Dripline is to be installed at a depth of 4”-6” (10.2-15.24 cm) in subsurface and groundcover applications. Use only XFS or XFS-CV dripline in subsurface applications. XF Series Dripline may also be installed on-surface under mulch in shrub and groundcover applications.
If you are not quite sure of the soil type, here is a test you can use by squeezing the soil in your hand:
Clay - When dry it forms hard clumps.. When damp it is flexible and can be molded into shapes..
Loam - A moderate sand or dirt and very little clay.. When dry it breaks easily.. When wet it forms a lump..
Sand - Soil particles are loose, sandy grains.. When dry it will fall apart when you open your hand.. When damp it will form a lump but it will crumble easily when touched..

CENTER FEED LAYOUT
Where layout flexibility exists, it is recommended that Center Feed layouts be used.. This allows for the most even flow of water through the zone.. Center Feed layouts also potentially allow you to increase the size of the zone by providing lateral runs on both sides of the supply header.. Center Feed layouts are an excellent option for median strips, road sides, and other homogenous planting zones..

OTHER COMMON GRID LAYOUTS
BRANCHING OUT OR JOINING LAYOUTS
When branching out from a supply header with XF Series dripline, maximum lateral run length should be considered.. Add up all the “branched out” dripline and check it against the maximum lateral run lengths listed in Tables 6, 7, 8, or 9.. This will vary depending on the type of tubing being used..
When joining lateral rows from a supply header, check only the longest lateral against the maximum lateral run length listed in Tables 6, 7, 8, or 9..

DESIGN CONSIDERATIONS
•Header should be spaced 2” - 4” (5cm-10..2 cm) from hardscape or other planting areas
•Headers may be QF Header, PVC, blank poly tubing or dripline
•Lateral spacing is a design consideration and can be calculated as shown on page 19 in “How to Calculate Equal Lateral (Row) Spacing”
•The lateral run length should not exceed the maximum lateral run length shown in Tables 6, 7, 8, or 9
•When using “Center Feed Layout” the run length should be measured from the supply header to the flush header and should not exceed the maximum run length shown
•When using “Loop Layout”, because water is split into two separate paths that meet in the middle, the total continuous loop length of dripline should not exceed twice the maximum lateral length
•In subsurface applications an air vacuum relief valve should be installed at the highest point in the system to avoid back siphoning debris into the emitter
•Flush valves should be installed at the low point in the flush header or at the mid point of the loop layout

SLOPES
• The design of the dripline system should account for slopes on the site since runoff may occur at low points
• Slopes less than 3% do not require special design considerations
• Slopes greater than 3% should increase the dripline spacing by 25% in the bottom 1/3 of the zone
• Dripline should run perpendiculur (across) the slope when possible

HOW TO CALCULATE EQUAL LATERAL ROW SPACING WHEN MAKING CUSTOM PVC HEADERS
Loam soil is assumed for the example below with a recommended lateral row spacing of 16”-22” as shown in Table 2 on Page 13.. To calculate the specific lateral row spacing within this range, you need to know the width of the zone being irrigated and then use the calculation as show in Example 1..
Example 1: How to Calculate Equal Lateral (Row) Spacing
•Application width = 8’ (2..4 m)
•Convert into inches: 8’ x 12” = 96”
or (Convert into centimeters: 2..43 m x 100 = 243 cm)
•It is recommended to space dripline 2” (5 cm) from hardscapes and 4” (10..2 cm) from separate planting zones
In this example there are hardscapes on each side of the planting zone.. Remove the hardscape spacing on each side from the total width:
96” - (2x2”) = 92” (243 cm - (2x5 cm) = 233 cm)
•For loam soil, the range of lateral row spacing is 16”-22” (40..6 cm - 55..9 cm).. Choosing 18”, calculate the number of spaces between rows: 92” ÷ 18” = 5..1 (233 cm ÷ 0..45 m = 5..1).. Round to get whole spaces.. Round up if the decimal is 0..5 or higher, round down if it is less than 0..5.. In this case you should round down to 5 whole spaces between rows..
•Calculate the equal lateral row spacing: 92” ÷ 5 = 18..4” (233 cm ÷ 5 = 45 cm)
•Calculate the number of dripline rows by adding 1 to the number of spaces between rows: 5 + 1 = 6 dripline rows
