We all know how difficult it is to justify a renovated
irrigation system, much less a new one! With different
types of equipment, being manufactured today, any AD
can achieve healthy, safe, aesthetically pleasing turf
while saving water and MONEY!
This is the perfect time to attend an educational turfgrass
and irrigation-related conference, which typically take
place from October to March in every state. The Irrigation
Association (www.irrigation.org) has an excellent educational
program/ conference offered in November. Not only will
various irrigation courses be taught, but the expo is
a showplace for all new and innovative types of equipment.
Listed below are a few updated and efficient water-saving
products and special features to look for:
•
Pressure regulating valves and sprinklers. Reduce high
pressures and eliminate misting from the sprinklers.
Pressure is the number one biggest variable in an irrigation
system.
•
Adjustable arc sprinklers. Eliminate overspray on hardscapes
and areas where irrigation is not needed.
•
Drain check valves in sprinklers. Stops low-head drainage
after sprinkler system has shut off. This is due to elevation
change in the sprinkler pipes.
•
Rubber covers and higher pop-ups on sprinklers. Safety
first! Small exposed covers that are made out of durable
rubber offer maximum protection during play on a field.
With more and more water restrictions taking place, turf
grasses are being mowed at a taller height. It is very
important to make sure the sprinkler pops up high enough
to shoot over the grass blades and there is no deflection.
•
Battery operated controllers. When there is no electricity
available, but water is near, irrigation systems can
now be used with a simple, easy to operate battery-operated
controller.
•
Rain and other weather shut-off devices. When it is raining,
the irrigation system should not be operating and these
devices automatically shutoff the controller when the
weather dictates it to.
•
Remote controls for your automatic timer. Check irrigation
heads and complete system with the ease of a remote control.
This makes a job easy for one person instead of two!
Other system considerations could be:
•
What type of pipe is currently installed? If it is old,
possibly galvanized, the interior of the pipe has probably
corroded and needs to be replaced.
•
What is the main water source? Are there alternatives
such as recycled, gray, new city tap and/ or a well with
a pump?
•
Is there enough pressure to run larger turf sprinklers?
If not, check with a local irrigation distributor and
they can help determine what size pump you might need.
•
Is there a current as-built design of the existing field?
If not, think about hiring a professional contractor
or designer to help create a plan that shows where everything
is located. If you are looking at a new system, make
sure this is one requirement that is not overlooked by
the contractor.
•
With new systems, determine what areas on your fields
are priorities for irrigation. Make sure the sprinklers
are designed and installed within these specific areas,
separately from the other locations. Then, if there are
any water shortages, the critical areas can still be
watered (middle of football field, etc).
•
If you are unsure if your existing system is operating
efficiently, check with local distributors for professional
references of contractors who can conduct a water audit
and show you hard data regarding uniformity and efficiency.
As we all know, water is our most valuable resource,
and needs to be managed properly in order to enhance
risk minimization and aesthetics. Take advantage of this
season to become more educated on basic hydraulics, system
components, installation techniques and overall irrigation
maintenance techniques.
