The four product lines are currently being tested on three tees each. SDI requires placing drip lines four to six inches beneath the surface to supply water directly to the root zone through emitters, ideally spaced 12 inches apart. The flow rate is between a half-gallon and two gallons per hour and most emitters are pressure-compensating.

Do golf courses have irrigation?
Many golf courses also have landscape systems for irrigation of areas around the clubhouse, pool, tennis courts, and entrance areas. These systems may or may not be on the same water source as the golf course. Many times, the landscape irrigation may be on a potable source and the golf course irrigation system on a different type of water supply.
What percentage of water do golf courses use?
Many golf courses use a combination of sources, hence the total percentage in the list is over 100%. For example, although water may not be pumped directly from a well into the irrigation system due to the large flow required by the irrigation system, the well is instead used to fill an irrigation pond.
What is the pressure of irrigation on a golf course?
Golf course irrigation sprinklers operate at high pressures–65 to 100 psi at the base of the sprinkler, requiring 110 psi plus at the water supply. The pressure may be created by a pump in the water source or boosted if a pressurized potable or effluent source is being used.
How do golf courses irrigate their ponds?
The pond will then have a large pump station to provide the larger flow required to irrigate the golf course in an appropriate time period. An increasing number of golf courses utilize effluent/recycled water to irrigate their turf, if it is available to their facility.

Do golf courses have irrigation?
In fact, almost all greens and tees are irrigated or have an irrigation system installed. Great golf courses will even have the fairway and rough areas irrigated, too. Here, you’ll find a practical guide to an average golf course irrigation system, including the types of irrigation, what makes up an irrigation system, and much, much more.
Is Irrigation Important?
Irrigation systems are essential for golf courses, mainly because proper water mechanics will ensure that the grass stays healthy.
Where To Irrigate
Golf clubs must establish quality requirements for their courses. This requires club managers to work with players to create a dynamic course. Course designers use different types of grass across the 18 holes. The overarching goal for the designers is to have the highest quality grass on the greens.
When To Irrigate
In general, determining when to irrigate the golf course is done by observing several things in the field. For example, groundskeepers watch for when drought spots emerge. Additionally, they monitor the root zone to see if the grass dries out. Course managers prevent dry spots through timely and sufficient irrigation.
How Much To Irrigate
Advanced computer simulation models are used to determine the ideal amount of irrigation. Computer simulation models describe all relevant processes that occur in the soil-water-grass system. The models also calculate whether there is still enough moisture present in the soil profile to ensure the quality of the grass.
What Statistics We Need
To be able to advise where, when, and how much irrigation a golf course needs requires a few factors.
How does precision irrigation help golf?
With precision irrigation, you’re not only conserving water , but you’re also ensuring that fewer fertilizers and chemicals are being washed away on a daily basis. This helps the overall health of the turfgrass and optimizes the effects of the applications while at the same time reducing their overall use of fertilizers, because more chemicals and fertilizers are not being washed away and wasted due to overwatering.
How much does an irrigation system cost?
Today’s irrigation systems can range from $750,000 to $3 million-plus for 18 holes and, in extreme cases, exceed $5 million. That kind of money will get you a lot of new bunkers and then some.
How much does it cost to replace golf course bunker sand?
Comparatively speaking, golf course improvements can range in price. New bunker sand and drainage $150,000 to $350,000; and rebuilding greens $250,000 to 500,000 on average. What do all of these have in common? Unlike the irrigation system, they are all highly visible and can be immediately appreciated by a member or daily-fee customer. The reward for hitting that clean shot out of a new bunker sand or sinking a 10-foot putt on new greens is immediate. Everyone benefits. When was the last time you saw a golfer jump up and down with joy because you have new sprinklers around your greens? It doesn’t happen. No, irrigation system upgrades and replacements are a different animal and should be approached as such.
How does precision irrigation help superintendents?
With a central control system capable of precision irrigation, superintendents can control their costs for water, utilities and labor. They can also control irrigation by setting runtime minutes or application inches and let the system help calculate the other variables. These new systems can see exactly how much water will be applied and how long each area will need to be watered. By gathering essential information about how and when to irrigate the fields precisely, superintendents not only save money but also help the environment. This brings us to our next point.
How important is integrity of conductors and splices?
Whether you have a satellite system or a two-wire system, the integrity of the conductors and splices is also very important to reliable operation. Understanding the material of the insulators and integrity of the splices can determine life expectancy. And I can't overemphasize the importance of documenting repairs – even wire repairs due to high-energy events like lightning or tree roots compromising a wire splice. Is the system properly grounded? I can’t tell you how many times I have come across earth grounds that failed years ago or are insufficient for the components they are meant to protect. Is there a central control computer, if so, what features does it have? What features is it lacking?
Is precision irrigation good for golf courses?
When it comes to the proper care of golf courses, effective and precise irrigation is often overlooked. But it shouldn’t be. Precision irrigation can be a complete game-changer when it comes to not only the look and feel of the golf course, but also the impact it can have on golf course managers and superintendents’ bottom line for operating costs. The future can be uncertain, and times can be rough, which is why it’s critical to think of ways to save money. Adopting a precision irrigation practice, can save money for golf course managers and superintendents in the long run. Because of all this, it’s safe to say that the practice of precision irrigation is the next big thing to hit the golf industry.
Do golf courses need irrigation?
