IRRIGATION
SYSTEMS (coming soon!)
Tired
of dragging hoses? Then you need an automatic irrigation system
from Emerald City.
Sprinkler heads and piping are installed underground and connected
directly to your water meter. When it is time to water, the
nozzles automatically pop up and water the area and retract
when they are done.
Automatic irrigation saves money and water at the same time.
The system meters the water out exactly. Each head is calibrated
to release a certain amount of water (from 1.5 to 2 gal per
minute). With our sophisticated RainBird controllers, we can
put down exactly the amount of water required in each area
of the landscape. And we can do it on any schedule that meets
local requirements: odd even days, or specific days of the
week. We even have sensors that automatically turn the system
off in the event of sufficient rain!
Don't leave your hose running all night. Chose a water-wise
irrigation system from Emerald City and save.
Design: When you call for a consultation with our irrigation
designer, he will come to your home and create a landscape
plan. The head placement is set for overlapping coverage in
the turf areas while also providing adequate coverage for
the beds. Each circle represents a RainBird R-50 closed-case
rotor-driven head. They are equipped with a RainCurtain nozzle
for even distribution through its 25? radius arc. The square
symbols represent a RainBird 1806 fountain-type head equipped
with a square-pattern nozzle. The controller is the RainBird
ESP series and one of the most reliable and easy to use in
the industry. In fact it comes with lighting protection and
a 3-year warranty (as does our entire system). Finally, we
provide a MiniClik rain sensor that will override system operation
in case of rain that not only reduces cost, it saves your
reputation as not wasting water.
Irrigation Evaluation: We will evaluate your watering
needs to determine just the right type of system for you.
In some jurisdictions, you have the choice of determining
whether or not you can install a second ?irrigation? meter.
The advantage to the irrigation meter is that water usage
on that meter is not assessed a sewage processing charge.
To receive this savings, however, you will have to pay extra
for the installation of the meter. In some cases it is definitely
worth it; in some cases it is not. Emerald City can assist
you in this decision by running an analysis of your expected
water usage to determine the payback period for the second
meter.
In some jurisdictions, an irrigation meter is required. In
these areas, Emerald City will concentrate on reducing your
irrigation system operating cost. First we?ll determine your
soil type and calculate the in infiltration rate, or the rate
at which the ground will absorb water. We will then calculate
the optimum system run time to ensure that there is no wastage
through water run-off. In some cases, this will require the
system cycle twice in a day to ensure that there is sufficient
ground water for the plants. The result will be a run schedule
that optimizes getting sufficient water to the plants without
any waste.
The plan will be presented to you as an email attachment for
your initial review. When you receive the plan, consider if
there are any landscape changes (new beds, driveway pads,
fencing, retaining walls, patios or decks) and inform your
designer about these changes you are planning as these will
change the head locations. Expect to receive your complete
proposal in the mail within a week of your email plan.
Installation: Your system will be installed using our
?invisible installation? technique. The heads are located
on the property according to the plan. The sod is cut by hand
and each section is laid to the side. The trenches are then
excavated by hand and the dirt placed on tarps for complete
soil recovery and to protect the lawn. Once all the rigid
PVC piping* is installed, the dirt and sod are replaced exactly
where they came from and soaked back to grade. Unlike mechanically-trenched
methods that leave obvious trenches or seeded-in repairs,
the result is your lawn is returned to its original condition.
The plumbing contractor connects the backflow preventer and
certifies that it is performing within specifications. The
inspections division is notified to conduct the plumbing inspection.
The remainder of the system is installed by the irrigation
technicians, including the electronic valves, the sprinkler
heads, the electronic cable, controller and rain sensor switch.
As the lines are installed, the dirt and the sod are replaced
in the trench and watered in. The spray pattern for the sprinkler
heads is adjusted and the controller is programmed. By the
end of the third day, the system is installed and the installation
cuts are virtually invisible. The owner is instructed on the
operation of the system, delivered the backflow instructions,
As-built diagram, system warranty and final bill.
Maintenance: Once your system is installed, we provide
ongoing support through our IrriGuard plan. With this we take
care of all your system maintenance for five years including
winterization, system start-up and check-out in the spring,
and backflow preventer maintenance and recertification. Consider
this scenario?
It's November and you're on a trip. You glance at the weather
report and a cold front with freezing temperatures is heading
for home. Then you think, "Oh no, the irrigation system
is still on..."
That repair bill will run you around $300. But with IrriGuard,
you no longer have to worry. At the threat of freezing temperatures,
our irrigation technicians will automatically winterize your
system: we'll shut-off the water source and drain down the
lines. And we guarantee your backflow won't be damaged, or
we'll replace it!
We'll startup your system again in the Spring and make sure
the controller, every head and every valve are set and functioning
properly. And we'll conduct the mandated backflow preventer
maintenance and recertification.
