Limitations
4. Municipal Water Sources
Utility Water and Well
Water usually constrain
the flow available to a
Landscape Irrigation
System
5. Measuring Flow and Pressure
Example - Measuring
the flow and pressure
from a residential
hydrant
connection to hydrant
tee fitting
pressure gauge
ball valve
5 gallon bucket & stop
watch or municipal flow
meter
6. Proper Equipment: Rotating Sprinklers
A single sprinkler can
cover a large area, 20 to
60 foot radius
Needs a higher flow rate,
0.5 to 20 gpm
Needs higher pressure,
35 to 75 psi
Sprinklers are “constant
discharge” and do not
automatically provide
“matched precipitation”
when part-circles are
used
7. Sprayer Sprinklers
Wets a smaller area, 8 to
16 foot radius
Smaller water flow, 0.25
to 4 gpm
Less pressure required,
20 to 40 psi
Can wet rectangular
areas
Automatic “matched
precipitation when part-
circles sprinklers are
used
8. Bubblers
good applications in plant
beds
wets a small area
low pressure requirement,
15 to 30 psi
low flow rate, 8 gph to 2.5
gpm

Editor's Notes
Welcome
This session discusses some of the technical aspects of providing supplemental water to residential landscapes.
We are not going to get too technical, but rather introduce you to some of the concepts that are used to design a good irrigation system.
The true purpose of this session is to make you a savvy consumer of irrigation products and to get the most bang for your buck when you invest in irrigation. Some folks have natural technical skills and will be able to take this information and install an irrigation system in their landscape. For the rest of us in this class, this session will provide information that will be useful when making arrangements with an irrigation contractor to have a system installed.
So,
What is your water source? Do you live next to a river or a creek? Do you have a pond and is the pond big enough?
When the water supply is much bigger than the water demand, you have greater flexibility in the design of your system.
Or,
Are you going to use the same system that your drinking water comes from?
When using your drinking water supply, most likely your water supply will limit your irrigation system design
Measuring flow and pressure
The first piece of equipment needed is a pressure gauge. You will probably need a gauge that can read between zero psi and 100 psi. If you are out in rural part of the water utility, you may only have 50 or 60 psi.
The following example shows how to make these measurements from the outside hydrant. If you plan to connect your irrigation system to the mainline going to your house, and if you are not confident in your plumbing skills - now is the time to call a professional plumber or irrigation contractor.
Having said that, usable information can still be gained from making these measurements from the hydrant. These measurements will be conservative compared to the measurements made at the mainline. However, for a small-acreage system - they will be sufficient.
Downstream of the pressure gauge you need a valve to restrict the flow. A PVC ball valve is easy to use. You can purchase all the fitting from a hardware store. Remember that a garden hose fitting is not the same as a 3/4-inch pipe fitting. You can purchase a garden hose by 3/4-inch pipe adapter.
We could use sprinklers
Sprinklers can cover a large area with a single head. Generally speaking sprinklers have higher flow rates per head and require higher pressures in order to spray water over a larger area.
We could use sprayers
Sprayers wet a smaller area, have a smaller flow rate, and require less pressure.
Sprayers can wet round areas and rectangular areas.
Fundamentally there is not any difference between sprinklers and sprayers. It is generally accepted in the irrigation industry that:
sprinklers apply water in a narrow, rotating band of water
sprayers spray the whole area at the same time
We could use bubblers
Bubblers allow water to spill out of the top of the nozzle. This allows for water to be applied to a small area. This a good way to apply a large volume of water to a plant bed.
They do not require much pressure because the water is not sprayed far from the head. It might take several heads to cover a large plant bed.
